The height of the body is one ninth of the total length ; 
the length of the head is contained three times and two thirds 
in the total; the diameter of the eye is rather more than one 
seventh of the length of the head. ‘The opercle has a single 
point ; the opercles are scaly, and the preeoperculum is rounded. 
The lower jaw with a short fleshy appendage anteriorly. The 
pectorals are contained nearly ten times in the total length ; 
they are one third longer than the ventrals; the spine of the 
latter is nearly as long as the rays. The origin of the dorsal 
is on a level with the extremity of the pectorals, but somewhat 
behind the root of the ventrals, considerably in front of the 
middle of the length of the body. ‘The interspace between 
the dorsals is equal to one seventh of the total length. The 
maxillary reaches to the anterior margin of the eye.

XXX VI.—List and Revision of the Species of Anolidxs in the 
British-Museum Collection, with Descriptions of new Species. 
By A. W. E. O’Suaucunessy, Assistant in the Natural- 
History Department. 
SincE the date of the publication of Dr. Gray’s ‘Catalogue 
of Lizards in the British Museum’ large additions have been 
made to the collection of specimens of the group Anolis. 
Many of these additional specimens were examined by Mr. 
Cope some years since, and furnished him with the types of 
new species, which he described in the ‘ Proceedings’ of the 
Academy of Natural Sciences of Philadelphia. The following 
list is the result of a recent study of the entire series, and 
gives the names of all the species which appear to me to be 
represented in it. ;
