1 Cottunculus torvus is described in full by Goode, Bull. Mus. Comp. Zool., XIX, 212. 

 Mr. Goode counts D. VII, 14 ; A. 13.

 Sound. 



3 According to Liitken (Videusk. Meddels. naturh. Foren. Kj0b., 1876, 92), Coitus 

 hicornis Reiuhardt is identical with Icelus hamatus Kriiyer. It is thought by Liitken 

 that Coitus polaria Sabine is iirobably also the same lish, but if so, the description of 

 Sabine is very erroneous. Nos. 1053 and 1083 may therefore be erased, and the species 

 Icelus hamulus in the Sj'nopsis may stand as Icelus bicoinis. 



■* Icelinus, genus or subgenus nova for Artedius qaadriseriatua Lockington, character- 

 ized by the peculiar squamation, preopercular armature, and form of the body as 

 described in the Synopsis, p. 691. (Name a diminutive of Icelus.) 



^ Aktkdiellus Jordan. 



(Geuus nova; type Coitus uncinatus Reiuhardt.) 



This genus or subgenus differs from Icelus proper, apparently its nearest ally, in 

 having the skin naked and smooth. Centriderviichthys Richardson, an Asiatic genus 

 to which this and other American species have been sometimes referred, has the skin 

 prickly, and a large slit behind the fourth gill, the gill membranes being fully united 

 to the isthmus. (A diminutive of Artedius.)
