rounded ; they are arranged, as a ride, in 16 to 20 alternating, longitudinal, 

 but not very regular rows ; they are slightly larger and sharper in adult males 

 than in females. The enlarged scales on the middle of the belly somewhat 

 extend to the sides and are usually in 38 or 40 longitudinal series. The 

 femoral pores in the male are 10-14 on either side, very rarely united 

 in the preanal region ; as a rule, they are separated by 1 or 3 or 5 scales ; 

 if 3 intermediate scales are present, which is very often the case, they are 

 arranged in a triangle. 



The specimen recorded by Theobald in Cat. Rept. Asiat. Soc, p. 30, 

 under the name " S.fasciatus, Gray (?)" is H. maculatus ; the former having 

 been described from an unknown locality must, therefore, provisionally remain 

 under that doubtful head, and not be added to the Indian fauna. 



The foui* specimens in the Museum from Ceylon, recorded by Theobald 

 in Cat. Rept. Asiat. Soc. p. 30, No. 41, as H. maculatus, belong to the larger 

 form ; two of them have the body about 3-f- inches and in one the tail is 

 3f, giving a total measurement of nearly 7 inches. In structure of scales, 

 tubercles and shields, the specimens do not exhibit any important difference 

 from maculatus, as usually understood, though at the first sight they 

 appear quite distinct. The two other specimens equal in size typical 

 maculatus, but when closely compared with specimens of this species, 

 they evidently possess a certain aspect of immaturity and tenderness 

 of the skin, &c. ; their heads are proportionately larger, and the same 

 is the case with the trihedral tubercles, which are present in a slightly 

 smaller number (14-16 rows) ; their colour is almost uniform whitish. 

 In the two adults, the differences are still more marked, and the 

 brown niarbling has an inclination to form transversely arranged bands, 

 very similar to a specimen described by Gunther under the name of H. 

 SyTcesi* The number of femoral pores is 32-36, in a slightly interrupted 

 series. For this Ceylonese form, Kelaart proposed the name H. Pieresi 

 (Prod. Fauna? Ceyl. 1852, p. 159), and as far as can be seen from the 

 drawing of II. SyJcesi (in Gunther's Reptiles), the latter does not in any 

 way differ from the former, therefore, Kelaart's older name must take 

 priority. It also seems to me clear that Dum. and Bibron's largest specimen 

 of maculatus, of which they give measurements, is the Sykesi of Gunther ; 

 it is said to occur in the neighbourhood of Bombay, wherefrom Dum. and 

 Bibron received it. Dr. Gray is evidently the original observer of the two forms, 

 the small maculatus and the large Pieresi, as shewn by him in his ' Lizards' 

 p. 153, where he gives " H. SyJcesi, Gray, B. M." as the synonym of 

 maculatus ; and among the specimens of that species he quotes " a. In 

 spirits. Female ? India, Dukun. Presented by Col. Sykes." This is to all 

 appearance the only type of Giinther's species, bearing the name H. Sykesi.
