86 Mr. Bennett on some Fishes from Jamaica. 



neither Brown's Lacerta, No. 7, nor his No. 8, as I conceive. Three 

 of its eggs, as I suppose them to be, are sent in the phial. 



17. In the phial are some specimens of a native Leech of this island, 

 clearly nondescript. Tliey are slightly shrunk from the action of the 

 spirit, but they never, I believe, grow larger than the present ones were 

 originally. I put into spirit some individuals bearing ova on their abdo- 

 men ; and some others in which, there having been no moisture, the 

 young were adhering to the belly, which they continued to do for some 

 days. This species appears to be destitute of teeth, since none have ever 

 incised my skin, in any trial I made with them. 



18. Three specimens of Brown's Cancer, No. 1, taken from some 

 Mangrove Oysters, There are besides, in the phial, some of our Wood- 

 Ants, and other things not worth particular mention. 



As I have proceeded with this letter (currente calamo) I have felt 

 almost vexed at the length to which it was extending ; and therefore I will 

 not now add to it, except to say that I have no hesitation in acceding to 

 the offer you have made to me of giving my paper on the Manta a place 

 in your Journal, but I wish to have a few alterations previously made, 

 and these I will send you very shortly. 



I have the honour to be. Sir, 



Your very obedient and humble Servant, 

 E. N. Bancroft.

The Shark, numbered 4, evidently belongs to the aberrant section 

 distinguished by M. Cuvier in his genus Scyllium, as having the anal 

 fin placed farther back than the second dorsal, the temporal orifices very 

 small, the fifth branchial opening frequently concealed in the fourth, and 

 the lobules of the nostrils generally so prolonged as to resemble beards. 

 All of these characters, except the latter, are possessed by the specimen 

 transmitted with Dr, Bancroft's communication. The length of it is 

 about one foot, and its colour (in spirit) is brownish above, and some- 

 what fawn-coloured beneath, marked on both surfaces, over the whole
