THE FUR SEALS OF THE PRIBILOF ISLANDS. 



14. Pygosteus pungitius (Linun'iis). 



We obtained but oue siuall specimen of this fish, which was taken from the 

 throat of a specimen Osmerus dentex at Giautley Harbor. The dorsal and anal tin 

 rays are in greater numbers than is usual, being: D., IX, 11; A., I, 10. The ventral 

 spines are almost one-half length of head. 



Following are the dorsal and anal formulae of five specimens from Nushagak, 

 Alaska, collected by the Albatross:

In all, the ventral spines are slightly less than one-half of head. 

 15. Gasterosteus cataphractus (Pallas). 



We found this fish, abundant in the river at Grantley Harbor. They agree 

 perfectly with specimens from Kamchatka, the type locality. They also agree well 

 with Richardson's description and figure of Gasterosteus insculptus from Northum- 

 berland Sound. They are more robust than the southern form ; the caudal keel is 

 more strongly developed; the pectorals are a little longer and stronger; the spines 

 are heavier, the lateral plates reach farther down on the sides, and their posterior 

 edges are much rougher. 



This southern form is Gasterosteus serratus Ayers. (I'roc. Oal. Ac. Sci., 1855, 47.)

We have compared these specimens with specimens from the type locality of 

 Ammotlytes personatus, and we are unable to find any diflerence between them. The 

 specimens from Neah Bay near Cape Flattery show more rays in the dorsal and anal
