lena bay, Lower California; all noticed by the writer; and three 
rays found south of San Francisco by Prof. Jordan. 
e Myxiné may possibly prove to be identical with one previ- 
ously described from the coast of. Chili (Bdellostoma polytrema), 
as it is said that the number of gill openings was not accurately 
counted in the Chilian type, but there is also a difference in the 
number of teeth. Of the three rays mentioned, one is a Dasy- 
batis, the second is a form connecting Dasybatis with Raia, while 
a third is a Raia. 
Altogether about forty species of marine fishes have been noted 
by Prof. Jordan and myself during the past eighteen months, and 
as the former is only at the commencement of his labors, and has 
only searched the coast from San Francisco southward, it is prob- 
able that he will find several more between the latter point and 
Puget sound. 
From the immense stretch of sea coast included in Alaska, a 
continental line of more than twice the length of that of the 
acific coast of the United States, we may expect many additional 
species when the United States Fish Commission gets fairly to 
work upon it. 
Glypiocephalus pacificus and Glyptocephalus sachirus —The reason 
that these two species escaped description so long is probably to 
be found in the fact, that those brought to the market are brought 
from. Point Reyes, about thirty miles north of San Francisco, : 
where there was no fishery until about three years ago. Neither 
of these species is at any time taken in abundance, and both are 
absent from the market, with rare exceptions, during the winter 
months, so that it is probable that at that season they resort to 
deeper water. 
Scorpis californiensts—This species, hitherto believed to be of 
rare occurrence, has been ascertained by Prof. Jordan to be the 
most common species in the Santa Barbara channel, constituting 
the bulk of the catch taken for the Los Angeles market. 
Torpedo californica—This species is, I believe, rare in collec- 
tions. The only example in our local museum is the small alco- 
holic specimen which probably formed the type of Ayres’ original 
description. It was therefore with some interest that I observed 
in our market a large individual, taken in Tomales bay.
