into a point ; five-eighths the depth of the body beneath. The sides of the tail are suf- 

 ficiently distinctly keeled ; and there is no temporal band. In the first of these charac- 

 ters it comes nearest -S. Rivoliana or S. falcata, Cuv. and Val. ; differing, however, 

 from both, principally in the points in which they are said to agree with S. Dumerilii, 

 Cuv. and Val. With S. Lalandi, Cuv. and Val., it agrees in the two latter points 

 above mentioned ; but differs in the produced second dorsal and anal fins ; S. Lalandi 

 appearing from MM. Cuvier and Valenciennes' description not to disagree in this re- 

 spect with S. Dumerilii, Cuv. and Val. The individual described measured two feet 

 and a half long.

 following formula of the Lampris lauta, p. 183 of the Synopsis of Mad. Fish. (vol. ii.

 page, for " six vertebra more," read " two vertebree more."

This fish agrees with C, hippuro'ides, Raf., according to the brief account transcribed 

 by MM. Cuv. and Val., in having a row of larger dusky spots along the ridge of the 

 back on each side at the base of the dorsal fin, which is itself immaculate, whilst the 

 anal fin is also somewhat high and pointed in front. In these three points it is at 

 variance with MM. Cuvier and Valenciennes' elaborate description of their C. hippurus, 

 L. The individual described, however, by these consummate Ichthyologists was a male ; 

 whilst the only three which I have been able to examine closely, proved on dissection 

 to be females, though commonly supposed by the Maderan fisherman to be the male 

 of C. equisetis, L. Hence the Maderan fish, whether identical or not with the obscure 

 and doubtful C. hippuro'ides, Raf., is for the present better referred to C. hippurus, L. 

 Sufiicient ground appears for the suspicion that the above differences may be only 

 sexual. But were it otherwise, they would alone scarcely warrant its specific discrimi- 

 nation. 



CORYPH^NA NORTONIANA. " Delfim." 



This is a deeper fish than the preceding, in proportion to its length ; with the front 

 much steeper and bluffer ; indeed, nearly vertical ; the dorsal fin beginning also some- 

 what forvvarder. In the fin-formulfe, and number of the vertebrae (31), the two agree ; 

 and I have seen too few individuals at present to decide whether they really are distinct, 

 or only so in sex. But for its spotted body, I should be greatly tempted to refer it to 

 the imperfectly known C. imperiulis, Raf. (See Cuv. and Val., Hist. 9, 286.) In this 

 uncertainty as to both rank and synonyms, less ultimate confusion will result from a 

 distinct specific name, apphed provisionally, than from a doubtful reference. It is
