behind base of pectoral with its base being nearer latter than ventral, 

 inner margin of pectoral ^ of its outer and fin reaching below end of 

 base of dorsal, anal below last f of second dorsal, and caudal 3f in 

 total. His figure of a skin, 6 feet long, differs in some minor details 

 from my example, which however may be due to age. 



('Oduf, tooth, 'fiCTTTif, scale; hence Odontaspis, an old generic name 

 applied to the sand sharks, and here used with reference to the super- 

 ficial resemblance of this species.) 



Eulamia longimanus (Poey). 



Head about 6| ; depth 81; width of head If ; snout 2f in head ; width 

 of mouth 21; interorbital space ly\; height of first dorsal 2f ; of second 

 dorsal 7f ; least depth of caudal peduncle 4; lower caudal lobe 2|-; 

 pectoral 1-J-; ventral 2f ; upper caudal lobe 3f. Teeth all finely ser- 

 rated and upper but little notched on outer margins. Dorsal inserted 

 just after base of pectoral. Width of pectoral 2 in its length. Length 

 39 inches. Dried skin without data. 



Jaws of large example from West Palm Beach (G. B. Wood), Fla., in 

 1907. Another pair of jaws from the Gulf of Florida (Dr. G. Watson) 

 is probably this species. 



Eulamia menisorrah (MuUer and Henle). 



Head 6|-; depth 8|; width of head If in its length; snout 2|-; width of 

 mouth 2f ; tip of snout to mandible 3 ; interorbital space 2 ; height of 

 first dorsal 1^; pectoral 1; length of ventral to posterior tip ly^j least 

 depth of caudal peduncle 4f ; caudal 3 in rest of body. Teeth without 

 serrations, each with several small cusps. Length 25|- inches. Padang 

 (Harrison and Hiller), Sumatra. 



Also a very young example with same data. Edge of first dorsal 

 very narrowly margined with black, also ends of second dorsal and 

 caudal. 



Eulamia oxyrhynohus (MuUer and Henle). 



Head about 4f ; depth 11^; width of its head 2f in its length; snout 

 about 2Jq ; width of mouth 2|; interorbital space 3f ; front margin of 

 first dorsal 2|-; of second dorsal 4; of anal about 4; of lower caudal lobe 

 2y^-o ; pectoral If ; length of ventral 3f; least depth of caudal peduncle 3^ 

 in snout; eye 8; upper caudal lobe equals head; length 17| inches. 

 Dried skin without data, though probably from Surinam? (Hering?), 



It differs a little from Miiller and Henle's figure, most likely in respect 



to age, in having insertion of first dorsal a little more posterior or 



opposite posterior basal edge of pectoral, depressed pectoral not 



reaching beyond posterior basal margin of first dorsal, depressed first
