adjoining ones. The seventh segment is very short, the eighth is 

 cornparatively elongate, curved, furnished with three stronger 

 spines at the dilation near the base and with a row of about 

 20 short and curved spines at the inner margin. The claw is 

 long and falciform ; exceedingly small auxiliary claws being im- 

 planted at the base of the claw. 



The single representative of this species must have been taken 

 at Station 147. December 30, 1873. Lat. 46° 16' S. ; Long 48° 

 27' E.; Depth 1600 fathoms; bottom temperature : 0°.8 ; bottom: 

 globigerina ooze. 



3. Colossen deis japonica , n. sp. 



(Fig. 11-13.) 



No species of Colossendeis has been observed hitherto in the 

 Northwestern part of the Pacific. Amongst Crustacea from the 

 Challenger Expedition Prof. G. O. Sars found a specimen of a 

 forra of this genus. It was dredged at Station 237, 17 January 

 1875 at a depth of 1875 fathoms : this happened at Lat. N. 34° 37' 

 and Long. E. 140° 32' not very far from the coast of Nipon, off 

 Cape King. 



It is a small individual, the body measuring 11.4 m.m. only. 

 The legs are rather long: 40.3 m.M., 3.5 tinies as long as the 

 body. In general it resembles C. minuta, Hoek. Yet it differs in 

 so many respects, that it would be hazardous to consider them as 

 identical. I propose to call this species C. japonica. 



The proboscis is cylindrical, slightly swollen in the middle, 

 one eighth Jonger than the length of the trunk with the abdomen. 

 The lateral processes are not widely separatecl from one another. 

 Palpus long and slender, exactly twice as long as the trunk: 

 once and three quarters the length of the proboscis. The third 

 joint by far the longest. The last three joints relatively long and 

 slender and furnished with short but strong hairs. 



The ovigerous legs are of the ordinary form. A considerable 

 part of that side of the surface of the four last joints which is
