of caudal fin on outlines of caudal peduncle, which are so conspicu- 

 ous in stomata and boTlmanni. In stomata there is a narrow rounded 

 cutaneous flap, with conspicuous white margin, on lower edge of 

 interopercle just behind mandibular articulation. This is present, 

 though smaller, in boTlmanni, and is barely perceptible in macrops. 



E. stomata was originally known from two specimens taken in deep 

 water off San Diego. It has since been dredged by the Albatross at 

 a number of stations between Point Conception and Ballenas Bay, 

 Lower California, these being the limits of the range so far as now 

 known. The depth at which it has been taken ranges from 21 to 74 

 fathoms. By the expedition of 1904 a single specimen was obtained 

 at station 4303, off San Diego, at a depth of 21 to 24 fathoms. 



A table of measurements of H. stomata, H. boTlmanni, and H. 

 macrops is appended for purposes of comparison.
