ADDENDA 7. CARCHARIID^ CARCHARIAS.

This species should probably be omitted from our lists, as there is uo 
good evidence that any of our sharks are identical with the x>lumheus or 
the milberti of the Mediterranean. Probably C. cceruleus was originally 
confounded with it. The Eulamia milberti of recent American writers 
is probably the following species, which may be substituted, as— 
27. C. coeruleus Dekay. 
This species differs from C. xjlatyodon chiefly in the following respects: 
Head longer, the snout much less obtuse, its length from mouth equal to 
breadth of mouth ; distance between nostrils ^ less than length of snout. 
Teeth and fins as in G. 2)latyodon. Pectorals rather small, not falcate, 
Ci in body; caudal 4, rather narrow. New England to Florida; not 
rare.

Acad. Nat. Sci. Phila. 1864, 262; probably not Carchariaa milherti M. & H.) 
27 (h). C. lamia Raf. 
To the description on page 23 add the following: 
Head broad, depressed; snout short and rounded, nostrils midway 
between its tip and the front of the mouth; breadth of mouth greater 
than preoral leogtli of snout. First dorsal very large, commencing 
close behind the base of the pectoral, its height a little greater than 
the length of its base, its anterior margin concex, its upper angle 
rounded, its posterior border nearly straight, its lower angle pointed, 
its height about equal to greatest depth of body; second dorsal much 
smaller than first; pectorals at least twice as long as broad; upper 
lobe of caudal one-fourth the total length, twice the inferior lobe. 
Grayish, fins rarely darker at tip. Coasts of Europe, etc. The claim 
of this species to a place in our fauna is extremely questionable.

The species described as E. lamia on page 60 is probably distinct 
from the European species, and has been described by us (Proc. IT. S. 
Nat. Mus. 1882) as Carcliarias lamiella. In this description, on page 
61, tenth line, for height read size. In the thirteenth line, read “in not 
having the first dorsal higher”, etc.
