A letter from Mr. J. E. Gray, addressed to the Curator, was read. 
This letter refers to some species of Bats from Jamaica, which Dr. 
Richard Parnell had sent to Mr. Gray. Among these, Mr. Gray ob- 
serves, are some specimens of the genus Macrotis, a genus which he 
had recently established upon a Bat from Hayti, showing that this 
form is likewise extended to Jamaica. 
‘* The collection also contains a specimen of Arctibeus Jamaicensis, 
Leach, and some specimens of a new genus, which is very interest- 
ing, as being a Noctilionine Bat, with an apparent nose-leaf, bearing 
a much greater resemblance to the Leaf-nosed Bats (Phyllostomina) 
than even Mormoops, which, when he first described it, Dr, Leach re- 
ferred to that group. Indeed at first sight I was inclined to regard 
the new bat as belonging to the Leaf-nosed Bats; but on examination 
I found that the nostrils, instead of being placed on the leaf-like pro- 
cess, which is the character of that group, were on the under side of 
the nose- keel, and quite separate from it. 
“This genus may for this reason be called Phyllodia, and it is 
thus characterized :— 
‘‘Head moderate; nose rather produced, with a sharp-edged 
transverse keel, with the nostrils on the lower side of the keel, and 
an ovate, lanceolate, fleshy process on the middle of the upper surface; 
chin with a single, transverse, membranaceous fold, surrounding a 
triangular group of many small warts ; ears lateral ; tragus distinct ; 
wings long, rather narrow; thumb moderate, lower joint rather 
shortest ; wing from the upper part of the ankle; interfemoral mem- 
brane large, truncated ; heel-bone long, strong ; tail enclosed, half as 
long as the membrane, with the tip above it, and with a vessel from 
each side of its tip to the hinder margin of the membrane. 
«These characters show that this genus has much resemblance 
with Mormoops, and especially Chilonycteris, but it differs from the 
former in having no transverse membranaceous fold on the face, and 
from the latter, with which it agrees in having a membranaceous fold 
across the chin, in having a fleshy, erect, leaf-like expansion on the 
upper surface of the nose, which is wanting in that genus.” 
Mr. Gray proposes to name this species after Dr. R. Parnell, so 
well known for his works on the fishes and grasses of Scotland. 
Puyxiopia Parnettu. Phyll. auribus magnis, subacutis ; vellere 
cinerascenti-fusco, pilis ad apicem obscurioribus. 
The following note on the Spermatozoa of the Camel (Camelus 
Bactrianus, Linn.), by Mr. Gulliver, was then read :— 
“In my observations on the Semen and Seminal Tubes of Mam- 
malia and Birds, published in the Proceedings of the Society, July 26, 
1842, I have noticed the form of the spermatozoa of the Dromedary. 
As I am not aware that the seminal animalcules of the Camel and 
Dromedary have yet been described, I now exhibit drawings of them 
to the Society. 
«* Although the blood-corpuscles of the Camelide have the same 
form as the blood-corpuscles of oviparous vertebrate animals, it will be 
observed that the Camel, like the Dromedary, has spermatozoa of the
