308 Dr. J. E. Gray on the Giiemul 



counts seven sternal callosities ; but in the adult brought by 

 M. Leschenault there are only six. It is evident that he and 

 GeoiFroy had two different species. 



MM. Dum^ril and Bibron (Erpdt. G^n. vol. ii. p. 501) adopt 

 Cuvier's view, describing as the perfect specimen the one with 

 the quadrilateral posterior callosities, and figuring it at t. xxii. 

 f. 2a ; but the synonyma include both species. 



Dr. John Wagler, in his 'Nat. Syst. Amphib.' t.ii. f.22 & 23, 

 figures a half-grown sternum imder the names of " jTno/i?/^ 

 coromandelicusy Geoffroy, Tcstudo granosa^ Schoepf," a nearly 

 adult sternum of the Ceylon species with parallel posterior 

 callosities. 



There is in the British Museum a young specimen which 

 may be dififerent ; for instead of having the back marked with 

 various-shaped white spots or marblings, the back in spirits is 

 pale brown, with regular, round, dark brown spots, those of 

 the middle near the vertebral line being the largest, and those 

 on the front of the dorsal shield more or less conliuent, forming 

 three interrupted cross bands. 



It may be designated Emyda fuscomaculata. 



The inside of the hinder part of the shells has a group of 

 two or three concavities on each side of the part behind the 

 pelvis, producing a pair of more or less prominent convexities 

 outside. In one specimen [d) of E. ceylonensis there is a 

 prominence on the outside of the hinder part of the dorsal shell 

 over each concavity. 



The same is to be observed in the inside of the shell of Cy- 

 clanosteus senegalensis ; but there the cavity is single, more 

 circular, and deeper, so that the substance left is translucent. 



XXXIV. — Additional Notes on the Guemul. 

 By Dr. J. E. Geay, F.K.S. &c. 



From letters that I have received it appears that the Guemul 

 of Molina is still not understood. 



There are in the British Museum three distinct species of 

 deer to which this name has been applied ; and perhaps Molina's 

 account of it, which was only from reports of travellers, may 

 itself have referred to two or more species. 



Three species have been described ; and we have the skulls 

 of all the species, and specimens of two of the animals, in the 

 British Museum : — 



1. Furcifer anttsiensis (Cervus antisiensis of D'Orbigny's 

 'Voyage,' t. 20), from the Bolivian Alps.
