[bean-weed] collection OF FISHES 73 



AsTROLYTES FENESTRALis (Jordan and Gilbert) 



One specimen, 11-6 cm. long, British Columbia. 

 One specimen, 8 cm. long, Straits of Georgia, B.C., 1910, W. 

 Spreadborough. 



Pterygiocottus, new genus, Bean and Weed. 



Large cardiform teeth present in jaws, on vomer and on pala- 

 tines. Top of head as far down as suborbital stay covered with small 

 nonimbricated, ctenoid scales. Scales on back and sides arranged as 

 in Artedius and Axyrias, meeting behind dorsal fin. Scales on lateral 

 line ctenoid but almost entirely concealed. One or two cirri on nearly 

 every scale. A few scattered cirri on head. 



Gill openings very wide, the membranes united and free from 

 the isthmus. Mouth very large. A very large plumose tentacle on 

 the front of each orbit, and a similar smaller one behind each eye. 

 The smaller cirrus is about as in Archistes, from which this form 

 differs in the large preorbital cirrus and in the position of the vent. 



This genus appears to be most closely allied to Artedius, Axyrias 

 and Orthonopias if these are separable, differing mainly in the immense 

 cirri and in the teeth. 



Pterygiocottus from the Greek wood meaning a flap, Cottus (the 

 Sculpin). 



Type of the genus Pterygiocottus macouni.
