548 ON A NEW GOLDEN MOLE AXD YOUNG LIZARDS. 



" The following skull measurements (in millimetres) indicate 

 the slight dilferences in size : — 



Length. Breadth. Height. Dental Series. 



"Smith's type 33 20-5 15-5 13-5 



Dobson's specimen 34 22 17 13 



B.transvcmlensis 34-5 23-5 17-5 14-5 



" The teeth in the specimen of B. transvaalensis are in front 

 partly the milk and partly the permanent set. The 1st upper 

 premolar has no internal cusp. The molars are appreciably larger 

 than in B. villosus. In B. villosus the 2nd molar measures 2 mm. 

 in width ; in B. transvaalensis it measures 2*5 mm. ; and there 

 is an even greater difference in the size of the last molar. 



" The type has been deposited in the British Museum." 



Dr. Broom also exhibited an adult female of the large S. African 

 Lizard, Zonurus giganteits, with two newly-born young (PI. 

 LXXIV.), and three adult male specimens of the allied species 

 Pseiulocordylus tnicrole'p idotus. 



He gave the following particulars of Zomtrus giganteus : — 

 " The mother Avas given to me by Mr. F. W. Fitzsimons, F.Z.S., 

 of the Port Elizabeth Museum. On opening the box containing 

 the specimen on arriA^al in London it Avas found that two young 

 had been born on the voyage. The young differ in appearance 

 very considerably from the mother, being much more bi-ightly 

 coloured. Young specimens in the British Museum collection 

 are described by Mr. G. A. Boulenger as "light yellowish, 

 marbled and cross-barred with blackish brown ; the spines not at 

 all developed, and all the scales more strongly imbricate." 



'■ These young also show the marked imbrication of the scales 

 which is largely due to their having no supporting dermal ossi- 

 fication. This gives the tail especially a very different appearance 

 from that of the adult. The colour may be described as yellowish, 

 with, on the back, irregular cross-bands of black. The top of the 

 head is blackish, but in most of the antorbital region the yellowish 

 colour predominates. The scales round the eye are mostly bright 

 yellow, but there is a black spot on the upper eyelid and a less 

 distinct one on the lower. The 4th lower labial has a large black 

 mark, and a black mark extends above this on the upper jaw to 

 the eye. The scales above the tympanum are yellow. On the 

 back the light bands, especially towards the lower half, become 

 very distinctly reddish, and on the tail about half the scales are a 

 light brick-red. The legs are irregularly banded yellow and 

 black, and the front of the body is pale straw-coloured except the 

 neck, which has a number of large black spots. The young 

 measure about 5 inches in length. Mr. E. G. Boulenger assures 

 me that the young are feeding satisfactorily and look lively."
