Pachydactylus punctatus Peters.

So many species of the punctatus-ocellatus section of 

 Pachydactylus have been described within recent years 

 that it is highly desirable to have better knowledge of the 

 characters of punctatus itself. A series from Serowe 

 presents the following characters. 



Head rather depressed but not strongly so. Mr. Bou- 

 lenger,^ who identifies the Serowe species as punctatus, 

 places that species in the group characterised by " head very 

 convex." Snout rather long, about If as long as the eye, the 

 scales thereon several times as large as those on the back of 

 the head ; naso-rostrals in contact ; rostral 1 .^- to 2 times 

 broader than deep, not entering the nostril ; seven, rarely 

 eight, upper labials, and six, rarely seven, lower labials, the 

 first upper labial only very slightly separated from the nostril ; 

 ventral body-scales somewhat larger than the dorsal ; ear 

 opening rounded ; four subdigital lamellee ; brownish above, 

 with small dark spots and vermiculations. 



P. pardus Sternf.j" from Warmbad, G.S.W.A., is said to 

 agree with purcelli in respect to the rostral, which is twice 

 as broad as deep and bounds the nostril, but differs in the 

 rounded ear opening and the longer snout, which is 1^ times 

 the diameter of the eye; it differs from serval in the larger 

 eye and broader rostral; in serval this scute is a little broader 

 than deep and does not enter the nostril.
