example from lona Id. (No. 21959 Ak. Nauk SSSR), which was described by P. Y 

 Schmidt (1929, p. 414) as Myoxocephalus tuberculatus but shows no difference 

 from the former form. Its fin formula D X 16, A 14, P 17. 



The nature of the head tubercles is varied but still must be considered the 

 important characteristic for M. verrucosus (Bean) It usually has two high 

 blunt tubercles behind the eye, in addition to 1-2 tubercles of smaller size. 

 The occipital tubercle varies m form, usually compressed and with an additional 

 tubercle in front with which it is sometimes fused to form a single compressed 

 hig^ tubercle . In some examples the tubercles are weaker . Our examples have 

 no cirri on head or tubercles . Occipital and mterorbital covered by tubercles 

 without pores. Scapular spine sharp; three preopercular spines, upper short 

 3/4 of eye (m M. ochotensis Schmidt equals the eye). Above lateral line are 

 round bony plates covered with small teeth. In examples of 140 mm. the plates 

 are already well developed. Adult examples have inner surfaces of pectoral 

 and ventral fins with bony tubercles . Color not always similar . In some males 

 it is very bright, consisting of 3-4 dark, wide bars. Sometimes a dark bar 

 on the nape across the occipital. Abdomen is light without spots. Fins light 

 with a dark irregular line . Ventrals are very light, sometimes with two dark 

 perpendicular lines . 



Numerous hauls in the north part of Bering and Chukchi Sea indicate 

 M. verrucosus is the most characteristic and common in comparison with members 

 of the genus Myoxocephalus . 



33 . Myoxocephalu s axillaris (Gill) 



In the catches of the KRASNOARMEIETZ (1933) there is a single large 

 example of this species from (Imatra) bay Gluboka on Koriak Land (depths 40 

 meters, rocky bottom. Temperature 0.4°). D X, 17 A 13 P 17. 



TL 190 mm. Tubercles behind eye and on occiput covered with thick skm and 

 have well developed cirri. Above lateral line are bony plates. Probably to 

 be identified with this species are a few young from Anadyr Gulf, that have well 

 developed cirri but undeveloped tubercles (however they have more rays in the 

 pectoral fin). M. axillaris is close to M. verrucosus and the young are 

 difficult to distinguish. 



34. Porocottus bradfordi albcimaculatus (Schmidt) 



Four examples do not differ from the original description were caught 

 by E. Kardakova (April 4 and May 20, 1931) on Medni Id. in tide pools.
