not differ in any essential point of structure from the description given by 

 Griinther, who has evidently seen specimens from various parts of the Malay 

 Archipelago, from Ceylon, and also from Asam and Bengal, considering them 

 all to he identical. The same conclusion has been arrived at by Dum. and 

 Bibron in comparing Bengal and Javanese specimens. The Darjiling 

 specimen described by Anderson as N. Himalayanum must have had 

 accidentally a somewhat " flatter and more rounded" snout, as in four speci- 

 mens from the same locality the outline exactly agrees with that of Dum. 

 and Bibron's figure ; I also cannot trace any stronger webbing between the 

 fingers and toes, said to distinguish Himalayanum from platyurus. Darjil- 

 ing specimens agree admirably with Schneider's original figure, (in which 

 only the head at its base is shewn too broad) ; the proportion and form, of 

 the feet and their toes is exactly the same, the latter being contracted at 

 then bases, connected by a membrane* and provided with 5 — 7 transverse, 

 divided lamella. Schneider says there are 56 large subcaudals, and this is 

 exactly the number I count in a full-grown specimen, with the tail perfect, 

 and not reproduced. The femoral pores (16 — 20 on either side) are slightly 

 interrupted in the middle of the preanal region. The only difference consists 

 in the shortness of the first pair of chin-shields, but this cannot be more 

 than an individual distinction, if really correctly drawn. The glands which 

 are situated behind the ear, chiefly towards the lower surface of the head, 

 are quite as often absent as present. Out of four Darjiling specimens they 

 are very distinct in an old female, in one nearly full grown male they are 

 small, and in two somewhat younger specimens of opposite sexes they are not 

 at all developed. One of the principal distinctions of the specimen, named by 

 Dr. Anderson N. Himalayanum, might be sought in the presence of some 

 enlarged tubercles on the side of the body. A $ specimen from the Naga 

 hills (Asam) has no enlarged tubercles ; of the four Darjiling specimens 

 one full grown $ , and one half grown $ , each have a distinct row of slightly 

 enlarged tubercles at the side of the body, above the attachment of the 

 lateral dermal expansion. One nearly full grown $ has an enlarged tubercle 

 on one side and two on the other, just a little in front of the sacral 

 region ; the fourth specimen, a female, has the scales uniform granular. It 

 will be seen from these observations that no specific value can be attached 

 to the total absence, or occasional presence, of a few enlarged tubercles, as I 

 had already occasion to notice in different species of Hemidactylus. 



What is, however, very marked in all Asamese and Himalayan speci- 

 mens, as compared with the usual descriptions of platyurus, is the large 

 amount of dark coloration they possess. The general colour is olive, with 

 a slight bluish cinereous tinge ; the whole upper surface is densely variegated 



* Which is clearly shewn on the right hind foot between the 1st and 2nd and 2nd 

 and 3rd toes.
