250 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 56. 



nearer gill-opening than snout tip, 3f to -ih in snout. Nictitating 

 membrane below eye forward. Mouth greatly arched, wider than 

 cleft. Upper labial fold little longer, about fourth of upper jaw. 

 Teeth alike, 24 or 23 below, 25 above, edges entire, bases wide. At 

 front of upper I or 2 erect teeth and 2 or 3 in front of lower. Inter- 

 orbital broadly convex, 2-J- to 2^ in head. Gill-oponings about wide 

 as eye. Scales with 3 ribs ending in as many points and median 

 lono^est. First doi-sal origin opposite end of inner pectoral angle, 

 extended end behind reaching opposite ventral origin. Second 

 dorsal base aV)out 1-i of anal base and one-third above end of anal 

 base. Second dorsal end behind l\ to If lengths from its base 

 behind to caudal pit above, which larger. Tail 3^ in entire length. 

 Pectoral, If to If in head; ventral, 3. Color in alcohol ash-gray 

 generally, below whitish. Iris pale. Fins all ash-gray; hind edges 

 of lower, including lower caudal lobe whitish, or at least paler. 

 Border of long caudal lobe narrowly brownish. Length 310 to 314 

 mm., two examples. 



^VUied with ScoUodon lalandi (MtiUer and Henle) from the tropical 

 Atlantic of Central and South America. Compared with an example 

 of the American species, 425 mm. long, fromi Colon, the lower caudal 

 lobe in blackisli marginally, front half of pectoral entirely blackish 

 and inner half only pale, and rictal grooves equal. Although Pietsch- 

 mann describes the rictal grooves they are not indicated in his lower 

 view of the head. 



TORPEDO NARKE (Risso). 



Disk partly circular, width greater than iengtli for space about 

 equal to space between front disk edge and spiracle. Snout short, 

 slightly concave medially. ^Mouth small, slightly crescentic, with 

 longitudinal fold at each angle. Teeth small, about 34 rows above 

 and below. Spiracle twice size of eye, with 7 weak papillae. Eye 

 small, 4 in interorbital. Second dorsal about seven-eighths of first, 

 latter with front half above ventral bases. Second dorsal base more 

 than interdoi-sai spaos. Tail short, slightly over one-thiril of total 

 length. Upper caudal lobe slightly longer. Color in alcohol russet- 

 brown above, with scattered variable small white spots or dots, none 

 larger than pupil. White below, outer pectoral and ventral portions 

 broadly brownish submarginally. Length, 387 mm. 



Compared with Italian examples the present one differs in colora- 

 tion, or the presence of the minute v/hitish spots and the absence of 

 the five large black ocelli. Compared witli Torpedo torpedo (Lin- 

 naeus) from Italy, the spiracle fringes are found well developed in the 

 latter, besides tlie presence of usually five to seven dark blue-black 

 ocelli.
