Eulamia marianensis Fowler, Proc. 4th (1929) Pacific Sci. Congr., Java, p. 492, 



1930 (compiled). 

 Carcharinus latistomus Fang and Wang, Contr. Biol. Lab. Sci. Soc. China, Zool., 



vol. 8, p. 235, fig. 9, 1932 (type locality: Tsingtau). 



Depth 41/4 to 514 to siibcaudal origin; head 4 to 414, width 1% to 

 1%. Snout 2 to 21/3 in head, moderately obtuse; eye 914 to 111/4, 4% 

 to 61/2 in snout, 5 to 5% iii interorbital, orbital depth ll^ to 1% in 

 its length; dentary -width 2% to 3l^ in head, length II/4 to li/o in its 

 width, labial folds rudimentary or absent; teeth in 26 to 30 rows, 

 upper rather broadly triangl^lar with inner edges straight and outer 

 deeply notched, lower teeth narrower, more erect, with broad bases, 

 edges of all teeth variably finely serrated; nostrils about midway in 

 preoral length, width 2% to 41^ in internarial, front nasal valve 

 broadly obtuse with short point; interorbital 2 to 2% in head, broad, 

 convex. Gill openings equidistant, fifth shortest and fourth and fifth 

 above pectoral origin. 



Scales minute, quindentate and with 5 keels, finely velvety to touch. 



First dorsal origin opposite inner end of depressed pectoral angle, 

 front edge 1% to 1% in head ; second dorsal origin opposite first to 

 last third of anal origin, front edge 2% to 41/3 in head; anal origin 

 nearer ventral origin than subcaudal origin or midway, front edge 3 

 to 4 in head; subcaudal front edge 1% to 2, 1% to 2% in its own 

 length ; least depth of caudal peduncle 4 to 5 in head ; pectoral I14 to 

 14/^, width 11/4 to 14/^ in its length; ventral length 2l^ to 2% ; claspera 

 small, narrowly attenuated, pointed, not reaching hind ends of 

 ventrals. 



Body gray -brown above, whitish below. Fins more or less grayish 

 terminally. Sometimes subcaudal lobe with terminal blackish blotch. 



Madagascar, India, Singapore, East Indies, Philippines, Indo- 

 China, China, Melanesia, Hawaii. Known chiefly by the second dor- 

 sal smaller than the anal with its insertion further back and its broad 

 pectorals. Along side of head eyes in pale or whitish extending from 

 lower surfaces, also all around edge of snout. Its caudal is very long, 

 equals or exceeds interdorsal space or 214 in rest of body. 



The nominal Carcharinus latistoniMS Fang and Wang is largely in 

 agreement with the present species, having been based on a specimen 

 565 mm. in length. It seems to differ only in the shoi-ter and more 

 convexly rounded snout; also the broad mouth is shown a little 

 greater at the angles than the preoral length. The edges of the lower 

 teeth are not described. The profile figure shows the large first dorsal 

 advanced over the pectoral base, and the anal origin slightly before 

 that of the second dorsal, though both of these fins rather large or 

 about long as snout. Though the gill openings are said to be sub- 

 equal they are shown with the first longest and the others graduated 

 shorter to the last or most posterior.
