Chitonotus pugetensis (Steindachner) ' 



One male specimen, 87 mm. long, taken at low tide, at Ucluelet, 

 June, 1909. 



One female, 135 mm. long, in 30 fathoms, near Double Island, 

 Ucluelet, June, 1909. Young and Spread borough. 



The dorsal fin of this species is not correctly shown in the figure 

 published in Bulletin No. 47, U. S. Nat. Mus., pi. CCLXXXIII, 

 fig. 687, as the first three dorsal spines are much more distinctly 

 separated from the rest of the fin than there shown. We have exa- 

 mined the specimen from which this figure was made. 



The male of our Vancouver Island specimens is very dark and 

 has a large anal papilla. The first dorsal fin is high in front while in 

 the female it is low, reaching only to the base of the fifth spine. 



Artedius lateralis (Girard) 



Three specimens, 88, 114 and 117 mm., low tide, May and 

 July, 1919, Ucluelet, Young and Spreadborough. 



We are not at all sure that Axyrias, Artedius and Orthonopias 

 should be considered separate genera. The specimen numbered 366, 

 U. S. Nat. Mus., from which Girard's figure^ of Artedius lateralis was 

 presumably made is apparently either Axyrias harringtonii, Artedius 

 asperulus or Orthonopias triads. It has scales on top of the head, 

 the patches of scales meeting behind the dorsal and the preopercular 

 spine with the lower prong very narrowly bifurcate. As Starks has 

 shown^, the preopercular spine in Artedius and Axyrias differs funda- 

 mentally from that of Astrolytes in that when the latter has the spine 

 bifurcate, it is always the lower prong that is lost and there are still 

 two points directed upward, while in the former genera if there are 

 three prongs it is by splitting of the lower one, and we have two points 

 directed downward and backward. This point covers the description 

 of Orthonopias. Our specimens from Ucluelet have cirri on the head, 

 and a specimen, No. 24765, U.' S. Nat. Mus., collected by Dr. H. C. 

 Yarrow, at Santa Barbara, Cal., differs from Artedius lateralis in no 

 way except that it has scales on top of the head. 



One specimen, 8 cm. long, Comox, Vancouver Island, 1893, J. 

 Macoun. 



Six specimens, 5 -8-8 -3 cm. long, Skidegate Inlet, B.C., June, 

 1910, W. Spreadborough.
