ing the frontonasal from the frontal which in the rest of the series 

 are broadly or narrowly in contact. The small amount of variation 

 exhibited by this species is surprising when one considers its near 

 relative varia is so unstable. 



The whole series is also uniform in displaying the characteristic 

 pair of longitudinal dorso-latcral light lines. One male (No 63360) 

 has the normally faint gray markings of the throat intensified into 

 rich black blotches coalescing on the sides of the jaw, another male 

 (No. 62874) has most of the underside uniformly plumbeous except 

 for the limbs and a light area connecting them. 



A female in the Museum of Comparative Zoology, collected by 

 Dr. G. M. Allen at Mombasa on June 24, 1909, holds nine very ad- 

 vanced young; this number is unusually large.

2 (U.S.N.M. 49082-3) Kenya Colony. (Heller) 1911. 



It is a matter of great regret that Heller did not furnish the precise 

 locality for these two beautifully preserved skinks; both appear to be 

 females; certainly the larger one, measuring 190 (86 + 104) mm., is, 

 for she holds well-developed ova in which are embryos. This indi- 

 vidual is by far the largest of the eight examples now known. 



These specimens furnish fresh evidence of the very variable nature 

 of the head shields in this species. In No. 49082 there are 2 supra- 

 nasals on the right and 3 on the left ; one very enlarged nuchal on the 

 left corresponding to 3 smaller ones on the right; the seventh upper 

 labial is twice as large as any of the others. In No. 49083 there is a 

 single pair of supranasals ; one very enlarged nuchal not quite central 

 and flanked on either side by four large scales bordering the parietals; 

 in this skink it is the sixth upper labial which is twice as large as 

 any of the others. In my points (see Loveridge, 1923) 1, 3, 4, 5, and 

 6 both are in agreement with my Kenya sldnk and with the type. 



The stomach of one of these specimens holds a large hard-shelled 

 curculionid beetle and two big black ants which look to me like 

 PaltotJiyreus species.
