and conspicuous, of many facets, round in outline, and r^d in 

 colour. 



The upper antennce are stout and rather sliort ; first joint of 

 the peduncle longer than the second, and second considerably 

 longer than the third, though they are all of nearly the same 

 breadth ; the margins are nearly or quite free from setaj : tiie 

 flagellum contains three or four joints ; the first joint is much 

 the largest, about as long as the third segment of the peduncle, 

 it is broad and bears on its margin about sixteen long non- 

 tapering seta?, rather longer than the joint from which they 

 spring ; they are arranged somewhat irregularly in pairs, each 

 pair springing from a small papilla ; a similar arrangement is 

 described by Scott in ? Cyproidia brevirostris^ and from the 

 figure given by Stabbing it is evident that it is also present 

 in C. damnoniensis ; it probably indicates that the first joint 

 of the flagellum, though apparently single, is really formed 

 by the coalescence of several separate joints, each with a pair 

 of " olfactory setse/' for that is what the long seta:; appear 

 from their structure to be. The second joint of the flagellum 

 is small and bears two long seta?, and is followed by a very 

 slender but longer terminal joint with one or two seta? at its 

 extremity; in the antenna on the other side of the specimen 

 examined the flagellum was composed of four joints, there 

 being two short joints before the slender terminal one. The 

 secondary appendage is small and one-jointed and partially 

 concealed by the broad first joint of the flagellum. 



Tiie loicer antennce are slightly longer than the upper and 

 much more slender; the "gland-cone" arising from the 

 second joint extends about halfway along the sliort third 

 joint of the peduncle ; fourth joint rather more than twice as 

 long as the third^ fifth rather shorter than the fourth, all 

 with margins free from setse ; the flagellum is about half as 

 long again as the fourth joint of the peduncle and is composed 

 of four joints, each much shorter and narrower than the pre- 

 ceding, and bearing at the terminal extremity two or three 

 fine seta?. 



The mouth-p)arls I have not been able to examine in much 

 detail, but they a])pear to closely resemble those of C. dam- 

 noniensis^ Stebbing. The mandibles have a fairly well- 

 developed molar ; the apex of the inner plates in the maxilli- 

 peds is transversely truncate, with its outer angle rounded off. 

 The Jirst gnathojjod is rather slender; carpus shorter than 

 propodos, bearing distally a projection which reaches about 

 one third the length of the propodos and bears on its under 

 surface about ten seta? ; propodos only very slightly ex- 

 panded, palm not well defined, but bearing six pairs of seta?
