least numerous, although one striking" species was secured, 

 which seems to belong to the family Asterinid;e. but cannot 

 be accommodated in any genus, the description of which is 

 accessible to the writer. The abactinal surface is co\ered 

 with small rectangular plates arranged in regular rows. 

 These plates bear spines closely resembling paxilke in their 

 arrangement. The papuhe. or dermal branchiae, are found 

 on the dorsal surface onh'. The most striking feature of this 

 species is the peculiar ornamentation effected b}' conspicuous, 

 irregularly disposed rounded prominences scattered over the 

 dorsal surface, and resembling huge warts. I have seen no 

 similar arrangement of tubercles elsewhere among the 

 Asteroidea. 



Among the thirt\'-ocld species of serpent-stars and basket- 

 fish dredged on the pentacrinus grounds, were manv forms of 

 unusual interest to the zoologist, a considerable proportion 

 being probablv new species. This portion of the collection 

 is particularly worthy of careful studv in the hands of a compe- 

 tent specialist. The writer can do nothing more than indi- 

 cate the general nature of the collection, mentioning a few of 

 the more notable and striking forms, such as catch the atten- 

 tion in a hurried examination of the material. 



The OphuridcK are represented by species of Ophiiira. 

 (JpJiionuisiiiiu. Ophiozoiuu Op/i/Oh'p/s. Opliioiuilfa. OpJiio- 

 piCpa/c. Ophiotlixrcus. OpJiiocaiitJia. OpJiioi^-IypJia. and Op/i/'o- 

 raiiiax. 



A very striking form allied to Op/iioJinisi/iiii has the entire 

 dorsal surface covered with rounded, greath' j:)rojecting nod- 

 ides like cobble-stones of se\'eral colors in strikin"' contrast. 

 Similar nodules cover the dorsal surface of the arms, from which 

 they pass on to the disk, forming tix'e large bulging ridges 

 which meet at the centre of the back. Alternating with these 

 ridges are the broad, granulated and widely separated radial 

 shields. Below are seen the roughly pentagonal mouth- 

 shields, with conspicuous side mouth-shields, both being set 

 back a considerable distance from the angles of the jaws. 

 Eaclt upper arm-plate alternates with a series of three promi-
