The zoological collection of the National Museum, Prague (NMP) contains spirit (juvenile) as well as dry (mostly adult) specimens of horseshoe crabs (Xiphosura). Living horseshoe crabs are of immunological importance due to clotting agents present in their hemolymph. Here we summarize basic data about the mechanism of the immune system of these marine animals and its use in practice–the Limulus Amebocyte Lysate test–including the laboratory assays and handling with the animals. In the NMP collection, 82 specimens (16 dry and 66 spirit) of all four currently recognised living species of horseshoe crabs are present. They were collected in Indonesia, USA and Vietnam in 1872–1998; Limulus polyphemus from the USA is the most numerous species in the NMP. The collection contains no type specimens but three historical mounted ontogenetic series are present. The largest part of the horseshoe crab collection is 55 spirit specimens from the collection of Václav Frič (1839–1916) whose preparations were intended mostly for educational purposes. © 2015, Arachnologische Mitteilungen.

Wolf spider females are characterised by carrying cocoons attached to their spinnerets. Emerged spiderlings are carried on the females' opisthosomas, with the exception of three Japanese lycosid species who carry spiderlings on empty cocoons. Here, the same behaviour is recorded in a European spider: the drumming wolf spider Hygrolycosa rubrofasciata. Spiderlings of this species do not try to climb on the female's opisthosoma, even when they are adopted by a female of a species with a normal pulli-carrying behaviour. This behaviour occurs in Trechaleidae and four unrelated species of Lycosidae inhabiting wet habitats and is therefore regarded as an adaptation to the unsuitable environment.

The arachnological collection of the National Museum, Prague contains material preserved in ethanol and a microscopic slide of recent sea spiders (Pycnogonida: Pantopoda). The collection is small, containing only twelve specimens. A revision of all of them revealed the presence of nine species from five families: Anoplodactylus lentus Wilson, 1878, Boreonymphon abyssorum (Norman, 1873), Callipallene sp., Endeis spinosa (Montagu, 1808), Nymphon grossipes (Fabricius, 1780), Nymphon hirtipes Bell, 1853, Nymphon stroemi KrØyer, 1844, Nymphon tenellum (Sars, 1888) and Pycnogonum litorale (Ström, 1762). The material preserved in ethanol was collected in the North Atlantic Ocean and adjacent seas, the pycnogonid mounted on the slide was collected in Mediterranean. Four of the sea spiders came from the Sars collection (Bergen, Norway) and four specimens came from the V. Fric collection (Prague, Czech Republic). From these two sources, six specimens were mounted for exhibition and educational purposes. Although the collection contains no types, it introduces an interesting group of marine animals. © 2016, Arachnologische Gesellschaft e.V. All rights reserved.

The centipede collection in the National Museum in Prague contains type material of 16 taxa (14 species and two subspecies), of which 15 were described by Luděk J. Dobroruka and one by Karl W. Verhoeff: Allothereua wilsonae Dobroruka, 1979; Chinobius alenae Dobroruka, 1980; Lithobius corrigendus Dobroruka, 1988; L. creticus Dobroruka, 1977; L. erythrocephalus mohelensis Dobroruka, 1959; L. evae Dobroruka, 1958; L. magurensis Dobroruka, 1971; L. purkynei Dobroruka, 1957; L. tatricus Dobroruka, 1958; L. tatricus monounguis Dobroruka, 1958; Monotarsobius homolaci Dobroruka, 1971; M. krali Dobroruka, 1979; Pachymerium dilottiae Dobroruka, 1976; P. hanzaki Dobroruka, 1976; Scolopendra aztecorum Verhoeff, 1934 and Strigamia olympica Dobroruka, 1977. Of these 16 taxa, five were described from the Czech Republic, three from Slovakia and eight from other countries (Greece, Iraq, Kyrgyzstan, Mexico, Nepal, Russia and Uzbekistan). The eight taxa described from the Czech and Slovak Republics are now considered as junior synonyms but the eight taxa described from the other countries are still valid. © Petr Dolejš.

Hypselistes paludicola Tullgren, 1955 was mentioned only a few times in the literature since its description. After examination of the holotype, it can be concluded that Hypselistes paludicola Tullgren, 1955 is identical with Trichopternoides thorelli (Westring, 1861) syn. nov. © 2015, Arachnologische Gesellschaft e.V.
