these characters it comes nearest S. Rivoliana or S.falcata Cuv. and 

 Val. ; diiFering, 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 

 tins ; S. Lalandi appearing from MM. Cuvier and Valenciennes' de- 

 scription not to disagree in this respect with S. Dumerilii, Cuv. and 

 Val. The individual described measured two feet and a half long.

This fish agrees with C hippuroides, 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 fe- 

 males, 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. hippuroides, Raf., is for the 

 present better referred to C hippurus, L. Suflicient ground appears 

 for the suspicion that the above differences maybe only sexual. But 

 were it otherwise, they would alone scarcely warrant its specific dis- 

 crimination. 



CORYPHiENA NORTONIANA. " Delfm." 



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 somewhat forwarder. In the 

 fin-formulae, 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. imperialism 

 Raf (See Cuv. and Val., Hist. 9, 286.) In this uncertainty as to
