B. Back covered by transverse roivs of contiguous or over -lapping scales ; 

 sides by small tubercular or granular scales ; sides of the neck with a fold of 

 loose skin, which, as well as the parts surrounding it, is covered with granular 

 scales. Hemicordvlus. 



H. Capensis. Scales of the back quadrangular and carinated ; the num- 

 ber of transverse rows considerable, but from their being indistinct on the 

 back of the neck, where the granular scales abound, it is not possible to 

 reckon them with any certainty. About the middle of each side, a longitu- 

 dinal row of large scales amongst the granular ones. Scales of tail with 

 moderate spines. Belly with 8 longitudinal rows of square plates. Femo- 

 ral pores, 18. Colour above, dirty black, beneath, livid blue black. Length 

 1\ inches. 



This is the only species I have yet seen, which well belongs 

 to this section ; and the only specimen of the species which 

 I have had an opportunity of examining, is contained in the 

 Museum of the Army Medical Department, whither it was 

 sent, from the Cape of Good Hope, by Assistant Surgeon 

 Forde, of the 72nd Regiment. By its peculiar scales, it is at 

 once to be distinguished from the species of the foregoing sec- 

 tion. The mixed character of the scales on the sides, points 

 out its close connection with the species of the next section. 



C. Scales of the back and sides disposed in transverse rows, somewhat cir- 

 cular inform, and those of each row more or less separated by the intervention 

 of small granular scales. Neck with two folds of loose skin, and by the 

 mode in which they are disposed generally give rise to triangular depressions 

 behind the ears. Femoral pores in two rows, most distinct in the male. — 



PsE UDOCORDYLUS. 



s P. montanus. Scales forming the transverse rows small, somewhat ovate 

 and faintly carinated ; those on the sides largest ; scales of tail with mode- 

 rate sized spines. Colour above, brown or blackish brown, and transversely 

 divided at nearly equal distances by 7 or 8 interrupted yellowish bands ; be- 

 low, yellow or orange, with tints of red ; legs variegated by transverse yel- 

 low bands ; tail irregularly marked, black and yellow. Femoral pores 8 in 

 the last, and 4 or 5 in the first row. Length, from 10 to 13 inches. 



vS' V.fasciatus. Scales forming the transverse rows rather closely set, some- 

 what circular, and with elevated discs. Anterior margin of ear concealed 

 by three projecting horny scales, the lowest being largest. Colour above, 

 brown-black, variegated by 7 or 8 transverse rows of dirty white spots, 2 of 

 which rows cross the back of the neck ; beneath, light livid brown. Seven 

 femoral pores in the last row, and 4 or 5 in the first. Length, from 8 to 10 

 inches. 



s P. melanotus. Scales circular and small along the middle of the back, on 

 the sides larger and somewhat ovate, each with a faint carina, ending in a 

 rudimentary spine. Colour above, black, sides and belly orange yellow, 

 tinted with vermilion red. On each side of the neck two large black spots. 

 Ten femoral pores in the last row, and 8 in the first. Length, from 12 to 

 14 inches. The female has the back freely variegated with short yellowish 

 stripes. 



P. Algoensis. Scales forming the transverse rows, sub-ovate, each with 

 an elevated disc, and a faint carina ; those towards the dorsal line smallest. 

 Colour above, reddish brown, crossed by some imperfect yellow bands in the 

 male, and by 6 or 7 rows of yellow spots in the female ; sides and belly o- 

 range yellow, tinted with vermilion red ; two large black spots on each side
