 pout; yellowish -brown, with black spots on the back, along the dorsal fin ; 

 this fish is only rarely i ' long. That it is viviparous is already indicated 

 by the name; the young continue for four months in the body of the 

 mother, and are commonly born in December or January, although at 

 other times also females have sometimes been found with fully developed 

 young. Females have been observed with 300 young ; usually however there 

 are between 100 and 200. This species does not occur in the Mediterra- 

 nean, but in the North Sea from 50 to about 70° N.L. Some Ame- 

 rican species also of this genus are known, of which one attains the 

 remarkable length of 2'. Zoarces labrosus, Blennius labrosus Mitch., Cuv.
