as long as the last (.075). The tips of the anal rays are free from the 

 membrane, some of them for a distance equal to one-half the diameter 

 of the orbit. 



The length of the middle caudal rays (.235) is contained 4^ times in 

 that of the body ; the length of the external rays, four times. 



The length of the longest pectoral ray (.395) is nearly twice that of 

 the fifth dorsal spine ; it extends to the vertical through the root of the 

 sixth anal ray. 



The distance of the ventral from the snout (.27) equals three times the 

 long diameter of the orbit. The length of the longest ventral ray (.49) 

 is nearly one-half that of the body ; it extends to the vertical through 

 the root of the seventh anal ray. The tips of the rays extend beyond 

 the membrane, in one case about a third the length of the fin. The 

 ventral s are furnished with stiff setae on their under surface, following 

 the course of the rays.

Color. — The ground color of the upi)er part of the body is a light 

 grayish brown, on which are four markings of a darker brown, of which 

 the first three are band-like and extend below the lateral line, while the 

 fourth is widest below and sends only a narrow point below the lateral 

 line. Between the third and fourth large body-markings there is a 

 small blotch of similar color beginning at the lateral line and extending 

 downward a distance equal to about |- the long diameter of the orbit. 

 At the base of the caudal is a band-like marking similar in color to the 

 body-markings, and the posterior half of the caudal bears two obscure 

 bands of brown ; between the brown markings there is an area of yel- 

 lowish white. The top of the head is sienna brown. The cheeks are 

 brown of a darker tint than the rest of the head. The lower parts of 

 the head are yellowish white, as are the bases of the pectoral and the 

 anterior part of the belly. The lower parts of the body are grayish 

 white, dotted here and there with spots of milky white. The largest of 

 these milky white spots are not more than \ as long as the orbit. The 

 belly has some similar spots, resembling in this respect the male of Coi- 

 tus scorjnus subspecies gronlandicus, but the spots are much smaller 

 than in that species. The spinous dorsal is mainly very dark brown 

 with two light areas in its anterior and posterior parts. The second, 

 third, and fourth body-markings are continued upon the soft dorsal; 

 that proceeding from the fourth body-marking, however, is continued 

 forward forming a margin for the upper posterior part of the soft dorsal. 

 The ground color of the pectorals is a grayish brown. On this ground 

 color the upper portion of the fin, on its anterior surface, has several 

 bands of milky white bordered with sienna brown; the lower part of 

 the anterior surface is mottled with nearly linear markings of sienna 

 brown bordered with milky white. The markings of the posterior sur- 

 face of the pectoral correspond in the main with those of the anterior 

 surface ; but the tips of the membrane between many of the rays are
