ansorgei from British East Africa, aiul P. pli. nt/iliaiiiis from Nyassaland— the 

 liarpe remains distally a low ridge which is nearly parallel to the edge of the 

 clasper and bears nnmerons teeth at and near the point of cnrvature. The ridge 

 is raised into a slight lobe before curving dorsad. It is very remarkable that 

 the individuals from the Congo to Kamernn contrast so strongly in the harpe 

 with those found farther north and agree with the eastern ones. 



The two forms of the dimorphic female of P. pliorcas have the same sexual 

 armatnre : see Nov. Zool. iii. p. 592 (1896).

NOTE ON UROPLATES FUIBBIATUS LICEENITJS 



SUBSPEC. NOV. 

 BY THE HON. W. ROTHSCHILD, Pn.D. 

 (Plates III., IV.) 

 N October 25th, 19U2, I received alive an extraordinary Gecko from 



Madagascar, which turned out to be a form of Uioplatesjimbiiatus. It lived 

 till Jnly 1903, and shed its skin several times. The very beautiful eye is shown 

 on the plates. The most remarkable observations we were able to make were 

 that it used the fringe ronnd the lower jaw, legs and tail, to cling to the glass 

 or branches in its cage in the same manner as all Geckos use the toe membranes. 

 The tail is also prehensile, and the animal can bang free suspended by the tail 

 by folding the sides of the tail round a branch. As the first specimen received 

 dilferetl markedly from the description in the " Gatalogue of Lizards in the British 

 Museum," which describes the colour as reddish brown, closely covered with black 

 spots, while this specimen is in addition, as the figure shows, variegated with large 

 lichen-like patclies of white, I propose to call this form Uroplates fimhriatus 

 liclieiiius. I must, hnwever, do this with a reservation, as I have received another 

 specimen in August 1903, which is intermediate between my U. /■ licheiiiiis and 

 true U. fmbriatus ; therefore, although I treat the white spotted form for the 

 present as a subspecies, it remains very uncertain, till we get properly dated and 

 localised material, whether it is really a snbsjiecies or only an aberration. 



1 append Mr. A. W. Head's note on the fundus ocnli, figured on Plate IV. 



"The fundus ocidi of the right eye is magnified Ibl diameters. The colour 

 of the retina is a bright urange-red, stippled all over witli a darker tint, giving it 

 a granular but very translncent appearance. Standing out at right angles to the 

 retina, and entirely covering the disc, is a well developed cone-shaped pecteu, bnt 

 without plications, of a dark chocolate-brown colour, its base spreading out, and 

 fringed all round with irregular tufts of lighter brown pigment, embedded in small 

 patches of light orange, which lias the appearance of the orange red of the fundus 

 having been brushed off. The process extends well towards the lens, and gradually 

 becomes darker and more sharply defined towards the ape.x, which is curved. I 

 have been unable to trace any opa([ue nerve fibres in this species."
