by Steller to the speckled color of a frog. Western shore of Bering Sea 

 and Okhotsk Sea; not recorded from Alaska or the Aleutian Islands. 

 This description from 11 specimens from Petropaulski and Bering Island, 

 taken by the Albatross. This species is now recorded from Bering and 

 Medui islands, Petropaulski, and the mouth of the Amur River. It is 

 evidently abundant in western Bering Sea, but probably does not occur 

 among the Aleutian Islands or on the Alaskan coast. There seems to be 

 110 doubt that this species is correctly identified with Myoxocephalus 

 Htelleri, with which it agrees in fin rays and in the peculiar and charac- 

 teristic coloration. It agrees also with the description of Coitus decas- 

 trensiSj from which the figure, however, diverges in several important 

 details. It is highly improbable that Coitus mertensii and Cottus mar- 

 moratus can ever be satisfactorily identified, as we have only very brief 

 accounts of them, based on colored drawings. (Named for Georg Wilhelm 

 Steller.)

2356. MYOXOCEPHALUS MEDXIUS, B. A. Bean, new species. 



HeadSi; depth 4|; eye 4 in head. D. VIII, 17; A. 12; V. I, 3; P. 14; 

 C. 14. Profile of head and body gradually ascending from tip of snout to 

 sixth dorsal spine, thence tapering to caudal peduncle; ventral line almost 

 straight, slightly tapering to caudal peduncle ; longest dorsal spine almost 

 as long as longest ray, 3 in head including flap. Mouth moderate, max- 

 illary reaching about to vertical through middle of eye. Pectorals large, 

 reaching slightly beyond anal origin, the middle rays being as long as 

 the head ; ventrals moderately well developed, reaching anal ; anal origin 

 under third ray of dorsal, ending under fourteenth ray of that fin. Gill 

 membranes united, forming a fold across the isthmus. Preocular spines 

 moderate ; opercular spines but moderately developed ; 2 flattish tubular 



* Cottus marmoratus is thus described: 



"D. 8-14; A. 12; C. 14, etc. Une seconde espece, observee dans ces parages par les 

 naturalistes do lameine expedition, ne parait pas non plus se rapporter & aucune de celles 

 que nous avous decrites. Ce petit chaboisseau a deux fortes epines au-devant de I'o3il. 

 Deux autres pen alongees au bord du preopercule; une petite dirigee vers le bas an bord 

 horizontal du meme os, et une assez forte a Tangle de 1'opercule. Les rayons 6pineux de 

 la premiere dorsale sont assez robustes ; le ciuquieme est le plus long. Ce poisson a la 

 tete et le dos bruns, de grandes niarbrures brunes et blanches sur les cotes, et rougeatres 

 sur le ventre. La premiere dorsale est juune, avec une grande tache brune, qui part de la 

 pointe du quatrieme rayon et descend obliquement jusqu'au pied du septieme. La 

 seconde dorsale est rouge. La caudale jaune, marbree de roux. La pectorale brune a la 

 base et jaune ensuite. Le jauue est traverse par trois raies circulaires brunes pres de 

 1'extreraite des rayons. L'anale est blanchatre et tachetee de nombreux points rouges. 

 Nous ne connaissons aussi cette espece que par un dessin long de quatre pouces, com- 

 munique par M. de Mertens." (Valenciennes.)
