ear-opeiiinii;, passing through the axilhi, and stopping in the groin;

Kemarks. — I have given so detailed a color description for the reason 

 that specimens from such a small island mny not always be accessible 

 to my brother herpetologists. The description is the more to be relied 

 u])on as there are four specimens in the collection, all i^erfectly alike 

 and all characterized by the same distinctness and straightness of the 

 outlines of the lateral bands. 



These specimens are of the same size as those from xVldabra, along- 

 side of which they present a totally different aspect. One of the 

 Gloriosa specimens has only 20 scale rows (No. 20404), the others have 

 22, while in the three Aldabra specimens there are 24 scale rows. 

 There is, however, another structural difference which seems to me to 

 be of more importance, as I find the nuchal shields of all the four 

 Gloriosa specimens to be wider and with more arched outlines, against 

 the straighter outlines of the same shields in those from Aldabra. 



Dr. Boettger (Zool. Anz., 1881, p. '359) has described a specimen 

 from Nossi Be as variety A. cognatus. This specimen also has 22 

 scales round the body, but only three supralabials in front of the sub- 

 ocular; moreover, and I think this the chief difference from my ^. 

 fjloriosus, it is colored like ^1. j^fron?/, that is, without the lower two 

 bands so characteristic of the former. 



Judging from Dr. Peters's remarks (Reise Mossamb., Amph., p. 77), 

 the Ahlepharus occurring in the Comoro Islands is identical with our 

 Aldabra specimens. 



Looking at the map, it can not be denied that the Ahlepliari inhabit- 

 ing the four islands, or island groups, here mentioned have a rather 

 peculiar distribution, and it will at once be clear how necessary it is 

 to treat these closely allied forms carefully and in detail. 



Chamaeleo ropeii Boul. 



Four specimens (Xos. 10741-16742; 16745-1074()) were collected by 

 Dr. Abbott at the foot of Kilima-Njaro, and two by Mr. Chanler on the 

 Tana Biver (Nos. 20103, 20108).

]\rr. Chanler sends home two spei-imens from the Tana Kiver (XoSc

Cbam^leo tigris KriiL. 



Numerous specimens from the Seychelles by Dr. Abbott. Nos. 

 10715-10710 ; 20458. The exact locality of Nos. 20434-20439 is specified 

 as lie Mahe. 



Chamaeleo taitensis Stkind. 



Three sjieeimens collected by Dr. Abbott at the foot of Kilima-Xjaro
