CLUPEID^E CLUPEA 29 



35-200-40. Over forty scales in a cross series below dorsal, caudal 

 fin largely scaly. 



Whether ventrals are present or not we have no means of knowing. 



Least depth of caudal peduncle about seven and a half times in the 

 length of the caudal region, about three times in its own length, and 

 about five times in length of the caudal lobe. The caudal fin of a second 

 specimen is preserved on the block containing PHOC^NA OCCIDUA. 



This large, shadlike fish belongs evidently to the family of CLU- 

 PEID^E. Its elongate body and long anal fin place it in the vicinity of 

 the genus ILISHA, from which it differs obviously in~ the insertion of the 

 dorsal fin notably in advance of the anal and apparently in the short- 

 ness of the anal fin -itself, but of that we are not sure, nor can we tell 

 how long is the dorsal fin itself. 



In ILISHA Gray the anal fin is inserted under about the tenth ray 

 of the dorsal, but the fin extends farther back, with forty-eight rays. 

 In the section PELLONA Cuvier & Valenciennes, the anal fin is shorter, of 

 about forty rays, and the anal is inserted farther back. 



From both groups, ILISHA and PELLONA, our fish is separated by the 

 minute scales, smaller than in any living form of herring or shad. There 

 is no evidence of scutes in front of the dorsal fin, and the species is 

 probably not one of the double-armored herrings. In case it should 

 prove to be such, it will be distinguished from COPEICHTHYS (DIPLO- 

 MYSTUS) of the Eocene by its very small scales. 



We give the genus the name of ALISEA, Alise being a Hindu name 

 of a related species, ILISHA MOTIUS.

Type No. XXXV, the well-preserved skeleton and impression of a 

 herring found in the diatomaceous deposits in Hews Park near El 

 Modena, by Mr. E. E. Hadley. The type specimen lacks the head and 

 most of the fins, the body and the caudal fin being well-preserved. The 

 number of vertebne indicated is 58, about 33 + 25 58, a very few 

 being lost with the head. Depth about 4^4 in length to base of caudal ; 

 length of caudal lobes more than half greatest depth. Ventral small, 

 eight-rayed, inserted behind middle of body, midway between opercle 

 and base of caudal, about under middle of dorsal, which is mostly oblit- 

 erated; dorsal higher than anal, of about equal length and number of 

 rays, anal very low, its base as long as the caudal lobe or the base of the 

 dorsal; seventeen rays are counted. Ribs moderate, slender, shorter 

 than in CLUPEA PALLASI, the living species. The neural processes are 

 much shorter than in the latter, barely two-thirds as high, and straight,
