66 ME. THOMAS SOOTT ON THE 



Several specimens of this Isopod were included in the Bruce 

 collection ; they occurred chiefly amongst dredged material from 

 West Bay, Cape Plora ; a few were also taken amongst sand 

 near East Glacier, in the vicinity of Cape Flora. Prof. Sars 

 discovered the species " many years ago, rather plentifully in the 

 Harbour of Vadso at a depth of 30 fathoms." One of the largest 

 of the specimens in the Bruce collection measured about 2"3 

 millimetres. Besides the other characters that distinguish this 

 species, the meral joints of the last three pereiopoda are furnished 

 with one (or two) minute but distinct spines near the end of the 

 inside margin (see fig. 6).

A specimen of this species was obtained in a gathering of 

 Crustacea from the vicinity of Cape Flora. The dactylus of the 

 chelse was not so distinctly serrate on the superior aspect as 

 Scottish examples. This Isopod " occuis alon;< the whole Norwe- 

 gian coast from Yadso to Christiania ;" I also have it from various 

 parts of the Scottish coast. 



Genus Pseudotanais, G. O. Sars, 1880. 



PSEITDOTANAIS EORCIPATFS (LUIjeborff). (PI. 3. figS. 8, 9.)

This species was represented in the collection by a single speci- 

 men dredged in Giinther Sound at a depth of ten fathoms on 

 September 9th, 1896. The form of the chelae (fig. 8) readily dis- 

 tinguishes this from other species of Pseudotanais. P. forcipatus 

 is also represented in the British fauna ; it was moderately fre- 

 quent in a gathering of small Crustacea collected ia the Moray 

 Firth in 1895. 



Genus Gnathia, Leach, 1814. 



Gnathia elongata {Kroyer).

 A single specimen of a female Gnatliia, appaiently belonging 

 to this species, was obtained in some dredged material collected in
