The only species of Acanthu7'us yet definitely known from the 

 American coasts are A. chirurgus^ A. tractus and A. cceruleus. 



19. Cottus bubalis L. 



This species has been ascribed to the fauna of Greenland, but, 

 according to Liitken, it has not yet been found in that region. 



20. Agonus cataphractus L. 



Erroneously ascribed to Greenland,^, decagonus Bloch having 

 been mistaken for it. 



21. Prionotus punctatus (Bloch). 



A common West Indian species, appearing in nearly all of our 

 catalogues as a fish of our South Atlantic Coast. But I have 

 seen no specimens from any point north of Cuba. It is probable 

 that the very different species, Prionotus scitulus Jor. and Gilb., 

 has been repeatedly recorded as P. punctatus. 



22. Anoplarchus alectrolophus (Pallas). 



Described from the Gulf of Penshin, and therefore not yet 

 definitely known from Alaska. 



2.3. Blennius fucorum Cuv. and Val. 



Specimens of a Blenny found in the fucus in the open sea, out- 

 side of NewYork harbor, were referred bj'^ De Kay to this species. 

 De Kay's description is taken from Cuvier and Valenciennes, and 

 no evidence of the correctness of this identification appears In 

 local lists, Isesthes punctatus Wood has appeared occasionally as 

 Blennius fucorum. 



24. Hippocampus hippocampus L. 



(H. Jieptagonus Raf . ; II. antiquorum Leach. ) 

 A sea- horse from St. George's Bank has been identified with 

 this European species by Mr. Goode. His description does not 

 agree well with my European specimens, and I think that his fish 

 must belong either to H. hudsonius or to some species as yet 

 undescribed.
