sides. The oblique portion of lateral line rests on about seven scales, 

 and the externally visible tubes of lateral line begin at this point. 

 Posterior portion of lateral line contained lA to If in dorsal portion. 

 Scales of lateral line: Forty-five in dorsal portion, seven in oblique 

 portion, and eighteen in posterior portion. 



A slight notch behind fourth dorsal spine, the second and third 

 spines slightly longer than those following, the first little longer than 

 the fourth, the longest spine about 2^ in head. First two anal rays 

 spinous, but weak and flexible. Last dorsal and anal rays not joined by 

 membrane to caudal peduncle, the depth of the latter equaling the 

 length of its free portion. Ventrals long and narrow, nearly reaching 

 vent in males, consisting of one spine and three simple rays. Pector- 

 als with some of the lower rays longest, l^iu head. 



All of pectoral rays simple, fourteen in number. 



D. XX VII, 12; A. U, 27. L. 5 inches. 



Caudal fin truncate. If to IJ in head. 



Color: Dusky olive above, with irregular narrow longitudinal streaks 

 of bright coral red, and seven round black blotches above middle of 

 sides. Reticulating red lines and spots on top and sides of head and 

 snout. JSranchiostegal membranes dusky in males. Two red streaks 

 on base of pectorals. Dorsals somewhat dusky, marked with lines of 

 red spots. Caudal with three rather faint cross-bars. Pectorals, ven- 

 trals, and anal largely black in males, pale in females. 



Three specimens from station 2945, in 30 fathoms. 



Plectobranchus gen. nov. {Blenniidcv). 



Teeth conic, on jaws, vomer, and palatines, some of them canine- like. 

 Body scaly; lateral line obsolete, its course indicated by a lighter 

 streak on middle of sides. Gill slits not continued far forwards, the 

 membranes broadly united, wholly free from isthmus. Dorsal of spines 

 only. Anal with two spines. Ventral with one spine and three well- 

 developed rays. Lower pectoral rays longest, as in LeptocUnus. 



Type, Plectobra ichus evides sp. nov. 



65. Plectobranchus evides sp. nov. 



Body very slender, the depth nearly constant throughout, about one- 

 eleventh of the length. Caudal peduncle without free portion, its 

 depth 2^ in that of body. 



Head rather long,'4| in length, extending well beyond origin of dorsal 

 fin. 



Upper jaw with a broad inner band of minute teeth in front and on 

 the sides, the outer series enlarged, two in the front of the jaw dis- 

 tinctly canine-like. Teeth in the lower jaw similar to the outer series 

 above, in a single series laterally, forming a patch in front of jaw, where 

 two of them are much enlarged canines, the largest teeth in the jaws. 

 Vomer and palatines with bands of small but very evident teeth.
