I have been unable to distinguish the cement glands on the femur as described 

 and figured by Professor O. II. Carpenter for other species. (4 and 5.) 



This genus, established by Mr. E. B. Wilson in 1878, has been more completely 

 It-fined in a-eordance with modern requirement** by Professor G. 0. Sars (25). It is 

 very closely allied to Coniylochele (G. O. Bars), but the special features which 

 distinguish it from that genus are (</) the crown of setae at the distal extremity of the 

 proboscis ; (h) the presence of spines on the l>ody and legs. 



Two species are now descried, one of which I regard for the present as identical 

 with those derived from the ' Valdivia ' and ' Francais ' Expeditions.

Specific characters : 



Body with long lateral processes not very widely separated, these armed doraally with a stout 

 par. A pair of similar spurs on the cephalon. 



Legs with longitudinal rows of setae set in small tubercular bases. Pro pod as well covered with 

 111 and a proximal group ventrally of half-a-dozen spines. 



Oviger ten-jointed. Denticulate spines with three strong teeth at the base. 



Body rather robust, with long lateral processes not very widely separated. The 

 length of these processes is increased by a very prominent spur which occurs dorsally 

 on each. 



A very conspicuous spur occurs on the antero-lateral border of the Cephalon. 

 This is rather long, with a definitely constricted neck, and widens considerably into two 

 lobes bearing the chclifori, and l>etwecn which the proboscis arises. 



The Ocular tubercle is short and stout, rounded alx>ve, and bears four well- 

 developed eyes. It lies between the first pair of lateral processes and the neck. 



The Abdomen is of normal proportions, gently tapering, and not articulated to the 

 trunk. It is directed upwards, but does not extend beyond the posterior lateral 

 processes, and TTTOTI a few minute setae. The segmentation is distinct 



The length of the body is Cmm., and its extreme width is barely 5mm. 



The Pkcboaeii it ventral in origin, rising apparently from a pocket between the 

 chelifori, directed obliquely downwards. It is a little longer than the cephalic segment 

 gently tapering to a blunt point, the small triangular mouth being surrounded by a 

 tuft of small bristles.
