2G073, 27100, and 27391. The European species, G. gcdeus, is said to have the middle 
teeth of the jaws not reduced in size, ihe median tooth in each jaw with hasal cusps; 
the second dorsal half smaller than the first; the fins plain, etc.) 
Pages 22, 23, 24, 00. The groups called Carcharimis and Eulamia 
.should rather be considered as subgeneric sections of a single genus, 
which may stand as — 
1§.— CAKCIIAKBAS Rafinesque. 
(Rafinesqne, ludice dTttiol. Sicil. 1810, 44: type Squalus glaucus L.) 
The species of Carcharias should stand as follows: 
25. C. ifSaHJCias (L.) Cuv. 
26. C. obscaaB’fiBS (Le Snenr) Miiller &. Heule. 
In this species the very long pectorals extend beyond the end of the 
dorsal, and their outer margin is four times as long as the inner.

Slaty-blue, white below; caudal blackish, other fins with dark tips. 
Body stout. Head very short, broad, depressed, and bluntly rounded. 
Mouth twice as broad as long, its breadth about half more than length 
of snout; inner lobe of nostril very blunt; nostril a little nearer eye 
than tip of snout; upper teeth very broad, triangular, erect, coarsely 
serrate, not notched; lower teeth narrower, more finely serrate. First 
dorsal beginning close behind pectoral, a little higher than long, not 
falcate, its base 2.J in interspace between dorsals; second dorsal very 
s«nall, its base 5 in interspace; caudal moderate, 2| iii body; anal a 
little longer than second dorsal, and jilaced a little farther back; pec- 
torals rather small, not falcate, G in total length, reaching a little past 
dorsal; width of pectoral nearly two-thirds its length. L. 10 to 15 feet. 
Cuba to Texas; abundant in the Gulf of Mexico; the specimen here 
described being from Galveston.

Bluish gray, whitish below. First dorsal rounded above, inserted 
immediately above the base of the pectoral ; second near the middle 
of the base of the anal; pectoral one-third longer than broad, its ex- 
ternal angle rounded. Mouth arched, its breadth equal to its distance 
from tip of snout; snout short, rounded, a little longer than in C. lamia; 
eyes small; upper teeth scarcely notched on tbe outer margin. {Doder-
