ventral surfaces, as well as the brachial spaces', are also closely 

 covered with tubercles similar in form to those of the interbrachial 

 ventral surfaces. Oral angles covered with close-set, sharp, conical 

 tubercles,, which become, towards the mouth, somewhat indistin- 

 guishable from the dental papillae. Dental papillae and teeth similar, 

 conical and very acute. No oral papillae. 



Arms rather slender, uniformly tapered, with alternating annuli 

 of two forms, one with two rows of granules entirely covered 

 over with very densely set minute hooks, the other with 

 two irregular rows of smooth, naked granules. Ventro-laterally 

 on either side of the arms, in line with the annuli formed by the 

 smooth granules, there is a series of large, round, naked plates,. 

 In the arm bases, the hook-covered annuli are usually broken at 

 the dorsal median line by conical granules terminating with one 

 or a few thorny points. Ventral surface of the arms with rather 

 well spaced tubercles, which are conical or terminate with one or 

 a few thorny points ; these tubercles become rounded "äiid smooth 

 distally. The first and second tentacle pores without arm äpineä, 

 the third with one or two spines, the fourth with two or three, 

 and the rest with three. The arm spines of the basal pores are 

 somewhat indistinguishable from the conical or thorned tubercles» 

 but the rest are peg-like, nearly as long as the corresponding arm 

 joints, and bear two or three denticles at the end. The oral 

 tentacle pores and the first and second tentacle pores open by 

 means of short tubes bearing a few spinules.
