THE FUE SEALS OF THE PRIBILOF ISLANDS. 



The fins may be uniformly black with a narrow white tip to the soft rays, or may 

 be more or less varigated with white. On the soft dorsal these marks are in the form 

 of white spots which may become confluent to form one or two streaks. In some 

 specimens the caudal membranes are white in their middle portion, the rays remaining 

 black. The under side of the head and maxillary membranes are sometimes marked 

 with large blackish spots with ill-defined edges. 



In addition to the minute pores which lie at intervals along the course of the 

 lateral line, the latter gives off pairs of lateral branches each of which opens in three 

 or more small pores. The sides of the head are also thickly studded with pores. 

 Owing to the thickened integument the pectorals and ventrals are more largely adnate 

 to the body than in other species. 



The fin rays are as follows in 10 specimens :
