CRUSTACEA MALACOSTRACA. 



teeth on the surface (fig. 1 1), and the surface between these rows is concave. First pleopods in the 

 female uniramous. The uropods have the outer margin of the exopod serrated almost to the base (fig. 1 1). 



The eggs are few and very large. 



Length of the largest specimen, an ovigerous female, 24 mm. 



Occurrence. The specimens seen have been taken by the "Ingolf". 



South-West of Iceland: St. 78: 6o° 37' N. L., 27 52' W. L., 799 tin., temp. 4-5°; 4 spec. 



Among the specimens two are ovigerous females; the third specimen is scarcely adult, and the 

 fourth only half-grown. The station is very interesting: the trawl came up filled with enormous 

 quantities of various sponges, and the number of species of Malacostraca (especially belonging to the 

 orders Tanaidacea, Isopoda and Amphipoda) is really astonishing, probably larger than in any other 

 single haul secured during any expedition.

Occurrence. This species has not been brought home by the "Ingolf", but it has been 

 taken a number of times by different zoologists especially of recent years.

 Distribution. The species has previously been taken at Reykjavik in 20 — 30 fm. (G. O. Sars), 

 the Shetland Isles in deep water (Norman), the Hebrides (Norman), from there southwards on the 

 coasts of Great Britain and Ireland (various authors); further, at Holland (Hoek), various places in the 

 North Sea (Metzger); Skager Rak, Kattegat, within the northern part of the Sound in depths from 

 6'/ 2 to 50 fm. (Meinert); also, Bohuslan (Goes), south and west coast of Norway to Lofoten (G. O. Sars), 

 western Finmark (Birula, Appellof), western part of the Murman south coast to the entrance to the 

 White Sea, 61—67 fm. (Birula) and 35 fm. (Doflein); lastly, in the western half of the White Sea 

 especially in Onega Bay in 4—9 fm. (Birula). — It is thus a markedly boreal species which lives in 

 depths from but a few fathoms down to almost 100 fm. 



Remarks. I agree with the view accepted by Norman, G. O. Sars and some other authors 

 that C. Allmani is an independent species. The largest specimen I have seen is 63 mm. long; it has 

 come either from Iceland or the Faeroes.
