4 AXEL OHLIN, ARCTIC CRUSTACEA. 



I liave marked with y>dct. Lönnberg». I take advantage of 

 this opportnnity of ofFering him my best thanks for tbe 

 kindness with which he placed at my disposal his notices 

 about the localities of the species determined by him. 



Here as in my preceding paper, I have also examined 

 a small collection of Decapoda collected by Mr. Th. Wulff, 

 M. A., on his trip to Spitzbergen with the Swedish-Russian 

 Expedition for measuring latitudes, in the summer of 1899. 



The collections of the Arctic Expeditions 1898 and 1899 

 belong to the »Riksmuseum», (State Museum) at Stockholm, 

 tbose of the Expedition 1900 to the University Museum at Up- 

 sala, and Mr. Wulff's collection to the University Museum of 

 Lund, which collections have been kindly placed at my disposal 

 by the resp. directors. Professors Hj. Theél, T. Tullberg, 

 and A. W. Quennerstedt. To Prof. A. G-. Nathorst, who 

 first asked me tho work up these collections, I also wish to 

 express here my great gratitude. 



Our knowledge of the carcinological fauna of East Green- 

 land and the seas East of Spitzbergen, round King Charles' Land, 

 has been considerably augmented by these expeditions. As 

 far as I know, the only papers treating of East Greenlandian 

 crustaceans are Buchholz' important memoir in »Zweite 

 Deutsche Nordpolarfahrt in den Jahren 1869 und 1870 etc.» 

 1874 and a short list of Hansen, viz. »Pycnogonider og Mala- 

 costrake Krebsdyr» in »Meddelelser om Grönland», Bd. XIX, 

 1895. 



The following Decapoda and Schisopoda are recorded by 

 those authors as occurring off that coast, viz. Selerocrangon 

 horeas (Phipps), Selerocrangon ferox (G. O. Särs), Necto- 

 crangon ^ar (Owen), Hippolyte turgida Kröyer, Hippolyte polaris 

 (Sabine), Hippolyte groenlandica (J. C. Fabricius),? Hippolyte 

 incerta Buchholz, Bytliocaris Panschii (Buchholz), Hymenodora 

 glacialis (Buchholz), Nyctiphanes norvegica (M. Särs), Bhoda 

 Baschii (M. Särs), and Mysis oculata (O. Fabricius). 



This list must now be increased by the following species, 

 viz. Sahinea septemcarinata (Sabine), Bythocaris siniplicir ostris 

 G. O. Särs, Bythocaris Fayeri (Heller), Hippolyte Gaimardi 

 H. Milne Edwards, Hippolyte spinns (Sowerby), BJioda iner- 

 mis (Kröyer), Boreomysis nobilis G. O. Särs, Pseudomma 

 roseum G. O. Särs, Pseudomma Théeli n. sp., Erythrops abys- 

 sortim G. O. Särs, Erythrops glacialis G. O. Särs, Parerythrops
