Two other specimens had respectively B. 94, A. 80, and D. 94, A. 82. 

 The length of the pectoral, as might be expected in so long and narrow 

 a fin, varies somewhat ; and the proportional length of the first five 

 rays is not constant. No. 4 was measured while perfectly fresh ; the 

 others after a few days' immersion in alcohol. In the fresh fish, the in- 

 terocular space is not raised above the eyes, and the upper boundary of 

 the orbit is hard to define ; but, in alcoholic specimens, the interocular 

 space stands out as a narrow ridge of bone. Like the preceding species, 

 G. zacMrus is of rare occurrence in the markets, and is not taken in the 

 Bay of San Francisco. 



During the six months previous to March none were taken ; but the 

 dealers assure me that it usually makes its appearance, in limited quan- 

 tities, ill the spring months. Most of the dealers, however, do not dis- 

 tinguish between this fish and the preceding one, and sell both as " Sole." 



One dealer, who evidently knew the fish, describing it by its long pec- 

 toral, assured me that its flavor was superior to that of any other of our 

 species ; I mention this because I had myself previously come to the 

 same conclusion. Its flesh is very firm and white, and its flavor ap- 

 proaches that of the true sole. No. 4 is the largest I have seen, and 

 from the answers I obtain to enquiries, I believe it is beyond the average 

 size. The long pectoral, bluff snout, and presence of teeth on the colored 

 side of the mouth at once distinguish this species from the preceding, 

 as well as from every other species. The nostrils in this and the pre-
