ADDENDA — 7. CARCHARIID^ CARCHARIAS. 873 



This species should probably be omitted from our lists, as there is no 

 good evidence that any of our sharks are identical with the pliimbeus or 

 the milberti of the Mediterranean. Probably C. cceruleiis was originally 

 confounded with it. The Eulamia milberti of recent American writers 

 is probably the following species, which may be substituted, as — 



27. C. cfleruleiis Dekay. 



This species differs from C. plafyodon 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 lengtli of snout. 

 Teeth and fins as in C. platyodon. Pectorals rather small, not falcate, 

 (\h in bodj-; caudal 4, rather narrow. New England to Florida; not 

 rare.

 Proc. U. S. Nat. Mns. 18^2: Lamna caudata Dek. 1. c. 354: Eulamia milberti Gill, Proc, 

 Acad. Nat. Sci. Phila. 1664, 262; probably not Carcharias milberti M. & H.) 



27 (b). C. laBBiia 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 

 tlian i)reural length 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 convex, its upper angle 

 rounded, its i)osterior 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 U. lamia on page GO is probably distinct 

 from the European species, and has been described by us (Proc. U. S. 

 Nat. Mus. 1S82) as Carcharias 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.
