the three primary spines of related species. A line of small spines 

 follows each rostral cartilage, a patch consisting of three or four 

 series near lateral margin of disk opposite the eye, and the usual 

 band of depressed spines inside the angle of the disk, somewhat irreg- 

 ularly arranged, but not more than two or three series wide. The 

 sides of the occiput, the interorbital space and the snout with patches 

 of very minute prickles, barely visible to the naked eye. Similar 

 minute prickles form a band around inferior margin of snout. The 

 snout is much narrower and sharper than in JR. montereyensis, the tip 

 protruding, the anterolateral margins distinctly concave, the ante- 

 rior margin, as a whole, strongly undulated. The spiracle is very 

 large, but little smaller than the eye. The mouth is strongly curved, 

 the symphyseal area produced and fitting into a strong notch of the 

 upper jaw. The teeth have strong central cusps much longer than 

 the diameter of the base, and are arranged in definite transverse 

 rows with wide interspaces. One can also detect series which 

 run lengthwise of the jaw, nearly parallel with its margin. The 

 tail is very long and slender and the dorsal fins are widely separated; 

 the interspace slightly exceeds the length of the base of either fin, 

 and bears on its median line seven or eight small spines. In addi- 

 tion to the color marks already given for R. equatorialis, should be 

 mentioned the conspicuous pair of lengthwise black streaks along 

 interorbital area, the irregular dark line below the eye and a dark 

 spot below the spiracle. B. equatorialis is not very closely related to 

 any other American species. 



CHLOPSIS GILBERTI Garman. 



This species has been known hitherto only from the type taken 

 by the Albatross in the vicinity of Panama. Four specimens are here 

 recorded from station 4325, near San Diego, depth 191 to 292 fathoms. 

 They answer Garman's description in all details, save the size of the 

 eye and the width of the interval between the gill slits. The diam- 

 eter of the eye is a little less than one-third the length of the snout, 

 and is one-tenth or one-eleventh the length of the head. The inter- 

 space between gills equals the length of the gill-slit instead of one- 

 half that length. But both of these characters are subject to con- 

 siderable variation, and both are affected by the state of preserva- 

 tion of the material. In each specimen, the dorsal begins almost 

 immediately above the gill-slits, and the belly is without dark streak. 



VENEFICA TENTACULATA Garman. 



A single specimen 247 mm. long from tip of tentacle to vent, from 

 station 4389, off San Diego, depth 639 to 671 fathoms. Agreeing 

 with Garman's figure and description in all respects, except the length 

 of the rostral tentacle, which is, in this specimen, one-half the length 

 of the rest of the snout. The origin of the anal is below the ninety- 

 eighth ray of the dorsal. The gape extends beyond the eye for less
