at Beacon Hill, near Victoria, by Mr. Norgate, in 1894, 

 and sent to me for examination by Mr. Fannin. This 

 agrees with the description of the original type, the slight 

 differences separating that from Nemichthys scolofiaceus 

 of the Atlantic being constant. A generic character of 

 Nemichthys not heretofore noticed is the division of the 

 dorsal rays into two sorts, near the middle of the body, 

 the anterior series being much longer than the others, 

 and all being undivided or spine -like. This character is 

 shown in the accompanying plates, taken from the Na- 

 naimo specimen. This character does not exist in the re- 

 lated genus Avocettina.

For purposes of comparison, I present a figure of Avo- 

 cettina gillii, from a specimen (No. 679, L. S. Jr. 

 Univ. ) taken by the Albatross at Station 2860. The genus 

 Avocettina differs from Labichthys and Nemichthys in the 

 backward position of the vent, and there is no division in 

 the dorsal rays like that seen in Nemichthys. 



THE TROUT OF LAKE CRESCENT, WASHINGTON. 



Some months since Rear Admiral L. A. Beardslee, 

 U. S. N., called my attention to the splendid trout found 

 in Lake Crescent, a mountain lake in the Olympic Range, 

 above Port Angeles, Washington. These trout, accord- 

 ing to his view, were of two species, one or both of them 

 new to science. These are locally known as the " Blue- 

 back " and the "Speckled" trout. 



Recently, through the kindness of Mr. M. J. Carrigan 

 of Port Angeles, and Mr. George E. Mitchell of Fair- 

 holme, one specimen of the speckled trout and two of the 

 blue -back have been sent to me for examination. I find
