parallel to the ventral outline. This causes anterior rows to converge 

 towards a point in the middle of the side. Dorsal and anal in alcohol,

narrowly margined with black. Head 5.0 in length to base of caudal 

 (205 mm. specimen) to 4.8 (130 mm. specimen). Depth 7.4 to 8.3; pec- 

 toral 10.8. Eye 4.4 to 4.0 in head; snout 4.4 to 4.5; maxillarv 2.1 ; pectoral 

 2.2; longest ventral filament 3.9 to 3.5, in the largest and smallest specimens, 

 respectively; interorbital in eye, 1.5; maxillary extends to posterior margin 

 of eye. 



Head somewhat smaller, pectoral slightly shorter, scales somewhat fewer 

 than described for Lepophidium proratus (Jordan & BoUman) of the Pacific. 



Three specimens, 205, 187 and 130 mm. to base of caudal. Taken by 

 the "Grampus" in 7 fathoms of water off Galveston. Tex., (Station 10478) 

 March 9, 1917, trawl. 



Ophidion holbrooki (Putnam). 



No spine at tip of snout or on opercle. Head scaleless. Scales on body 

 rudimentary, embedded, linear, placed approximately perpendicularly to 

 one another in groups, as in Anguilla, variable in length, maximum approxi- 

 mately half pupil. Air bladder slender, tapering backward as figured by 

 Putnam (Proc. Bost. Soc. Nat. Hist. 1874, 342). Gillrakers 4. Dorsal

and anal narrowly margined with black. Head 4.0 in length to base of 

 caudal (in 232 mm., 8 % in. specimen) to 4.6 (in 152mm., 6 3^ in. specimen). 

 Depth 5.2 to 6.8; pectoral 10.4 to 10.5; eye 5.2 to 4.0 in head; snout 4.3 to 

 4.0; maxillary 2.3 to 2.3; pectoral 2.6 to 2.3 in head; longest ventral filament, 

 2.2 to 1.8; interorbital in eye 1.4 to 1.6; in the largest and smallest speci- 

 mens, respectively. Maxillary extends approximately to posterior margin 

 of pupil. 



These measurements give smaller head and other proportional differences 

 from (6 inch) holbrooki, as described by Putnam. As there is considerable 

 age variation we do not feel justified in describing our material as new on 

 that basis. 



Three specimens 232, 182 and 152 mm. in length to base of caudal. 

 Taken by the "Grampus" in 10^ fathoms, 11 miles SSW from Heald 

 Lightship (Station 10479) March 16, 1917, trawl.
