South Orkneys, Brown's liny, Station 32<iA. November 1 ( .)0:!. .Many specimens 



of about 10 mm. in length. 

 South Orkneys, Scotia, Bay, Station 325 ; dredge, 9-10 fathoms. May 1903. 



One small specimen. 

 South Orkneys, Scotia May, Station 325; dredge, 4 fathoms, gravel bottom, 



clumps of weeds ; temperature 29' 1. L'rd December 1903. Two specimens. 



These specimens agree minutely \vitli the figures and description given by CHEVREUX, 

 and 1 have been able to compare them with co-types of his species which he has been 

 good enough to send me. 1 have also compared them with a specimen of Anani/.f 

 l'< nini'iitus Pfeft'er from South Georgia, kindly placed at my disposal by the authorities 

 of the Hamburg Museum, and I find it is quite the same as the South Orkneys 

 specimens and those from Port L'harcot sent to me by Monsieur E. CHKVREUX. Pfetfer's 

 description agrees well with U. dentimanus, but his figure shows the telson too broadly 

 rounded posteriorly and the cleft too shallow. The figure was, however, made without 

 dissecting the specimen. His name has priority by many years. M. CHEVKEUX states 

 that this species appears to closely resemble C. /'mnjin'ri Walker from South Victoria 

 Land. I have been able to examine co-types of this species from the British Museum, and 

 also specimens obtained by the Xniir<i</ Expedition, and find that, though there is consider- 

 able resemblance in general structure, C.fougneri differs considerably from C. (L'ntimanus 

 in the greater length of the antennae, and also in having the body much less compact, 

 and the first gnathopod more slender.

Station 411, Coats Land, lat. 74 L' S., long. 22 W. ; Kil fathoms. Many 

 specimens, the largest 22 mm. long. 



After much consideration, I have decided to record these specimens under the name 

 given above. I have been able to compare them with the type of Mr WALKER'S species 

 obtained by the Southern Cross Expedition, and the two agree so closely that they 

 must be considered specifically identical. The eyes are obsolete, the lateral lobes of the 

 head produced and acute or suhacute, the hind margin of the third pleon segment straight,
