2b. Dorsal beginning above the gill opening; body bicolor only to a 

 point slightly behind the anal origin; no white canthal line; a 

 white band across nuchal region and another band across the back 

 at the origin of the dorsal fin ; lower jaw unmarked (Galapagos). 

 G. bicollaris, new species.

 Plate 9 



Holotype. — AHF no. 11. 



Type locality. — Station 798-38, Cartago Bay, Albemarle Island, Ga- 

 lapagos, at surface under electric light, January 21, 1938. 



Paratypes. — Three specimens, 170-195 mm., Station 73-33, North 

 Beach, Albemarle Island, Galapagos, February 13, 1933. 



Measurements of holotype in mm. — Total length 160, head and trunk 

 54, tail 106, depth of body 7, head 19, eye 2.8, snout 4.5, interorbital (not 

 bony) 3, gape 6, length of gill opening 1.5, height of dorsal at a point 63 

 mm. from tip of tail 2.5, height of anal at same point 2. 



Description. — Body rounded in cross section anteriorly, growing 

 somewhat more compressed posteriorly. Depth 22.85 in total length, head 

 8.94, head and trunk 2.96. Tail 1.96 in head and trunk. Snout 4.22 in 

 head, interorbital 6.33. Skin naked and smooth. Snout covered with fine, 

 short, hairlike papillae, which are more scattered on lower jaw and 

 other parts of head and gular region. Snout flattened dorsally and broadly 

 rounded in dorsal aspect. Head only very faintly swollen in occipital re- 

 gion. Interorbital broad, two thirds the length of the snout. Gape 

 barely reaching vertical from posterior margin of eye. Anterior nostrils 

 tubular and directed downward, placed almost at tip of snout, the length 

 of the tubes less than one-third diameter of eye. Posterior nostrils open- 

 ing downward in the upper lip directly below anterior margin of eye; 

 they have slightly raised edge, which is developed into a distinct flap on 

 the outer side, this flap folding down and concealing the opening. A 

 groove immediately follows the nostril and runs forward and toward the 

 inside of the mouth between the nostril and a conspicuous pore just be- 

 hind it. Gill openings small, oblique (at an angle of 40° from horizontal), 

 placed laterally at the center of the body depth, more than half the di- 

 ameter of the eye in length. Surface of gular-branchial region with a few 

 longitudinal folds. Jugostegalia not evident but possibly present. Four 

 pores anteriorly on top of the snout, two on each side just above and
