2 mm. The suckers are in two irregular rows and liave a 

 smooth horny ring. 



The tentacular arms are long (17 mm.) and stout, not 

 expanded distally to form a club. On the terminal 3'5 mm. 

 there are four rows of subequal suckers, which bear mostly a 

 few irregular blunt teeth on the upper half of their horny 

 ring. All along the ventral aspect of the stalk there are 

 2—3 rows of very small suckers. These are not too well 

 preserved, but ibey seem to have had minute cups and delicate 

 stalks. 



There are half a dozen chromatophores on the back of the 

 *' club " and one or two on the back of the stalk. The pen is 

 apparently very delicate, being clearly visible only at the 

 posterior end between the fins, where it forms a cone. It is 

 traceable up the mid-dorsal line as a transparent streak. 



A single specimen was taken on Aug. 31st, 1907, in 

 60° 3' N., 3° 53' W., in 505 m. It is, however, very probably 

 a surface form. 



Taonidium pfefferi is not unlike Taonidium suhtni (Lan- 

 kester), and, indeed, Dr. Hoyle, who examined the specimen, 

 put it down to that species. Dr. Pfeffer, however, was of 

 opinion that the specimen was specifically distinct, and 

 examination of the question has led me to share his opinion. 

 It differs from Taonidium siih mi in its broader shape, in the 

 order of the arms, structure of tentacle-stalk, arrangement of 

 chromatophores, and in the outline of the anterior mantle- 

 margin. In T. suhmi (Hoyle, Chall. Rep. xvi. (1886) 

 p. 192, pi. xxxii. figs. 5-11) the body is fusiform, with the 

 length more than three times the breadth ; the order of tiie 

 arms is 4, 3, 2, 1, there are no suckers on the stem of the 

 tentacles, the chromatophores are in about eight rows, and 

 the mantle-margin is straiglit. 



In some respects Taonidium pfefferi approaches close to 

 the genus Owenia, Pfeffer, with its single species Owenia 

 megalops (Proscii) ; but the two genera are probably hardly 

 distinct from one another. 



Tlie species is named in honour of Dr. Georg PfefFer, 

 Hamburg. 



Moschites cirrosa (Lamarck). 



Examination of specimens from Naples and from Plymouth 

 has convinced me of the identity of the common M. cirrosa 

 of our shores with the Mediterranean M. aldrooandi. Among 

 the specimens of Moschites collected by the ' Goldseeker ' 

 there are two distinct types — one tlie true aldrovandi form, 

 with its reddish colour and its arms all closely bound
