claw on the toes in the former and its presence in the latter. We have 
observed however that a minute claw is present in all species of 
P 'achy dactyl us at our disposal, the arrangement being precisely as in 
Elasrn odacty lus namaquensis , Sclat. (we have examined all the known 
species except P. fasciatus , P. amoenus , P. serval, and P. weberi). Mr. 
Boulenger ( vide Ann. S. A. Mus. Y, p. 456) has evidently observed the 
presence of claws on the toes in P achy dactyl as but endeavours to maintain 
the generic distinction of Elasmodactylus by contrasting the degree of 
dilatation of the digits: thus he writes “ digits strongly dilated” in 
Elasmodactylus , “digits more or less dilated” in P achy dacty las. We 
can only add that in our judgment P achy dacty lus bibroni and 
“ Elasmodactylus ” namaquensis are precisely alike in this respect. 
Text fig. 14. Toe of Pachy dacty lus bibroni var. laevigatus , from underside, with claw 
partially extended (diagrammatic) : enlarged. The claw seems to be retained in a minute 
circular muscular pad : a small scale above this pad and below the “nail-like” scale protects 
the pad from above. The claw can only be seen when the distal extremity of the toe is 
extended. 
We may mention that the claws are present only on the toes not on 
the fingers ( vide text fig. 14).

2 examples at Kraikluft, at an altitude of 5000 feet : 3100, length 
81 + 55 mm., tip of tail regenerated : 3101, length 75 + 82 mm. The skin 
of this Gecko is very loose, and is easily torn if the animal is roughly 
handled. Both specimens were taken in a deep ravine in crevices of rocks. 
In neither specimen does the first labial enter the nostril : the rostral 
is considerably broader than deep : the naso-rostrals are separated by a 
small scale : the tail is distinctly annulated, each annulus including seven 
rows of scales dorsally, the transverse row separating two adjacent annuli 
including five or six enlarged scales : the ventral scales of the tail are 
much larger than the dorsal ones. 
Type and co-type have been examined by us.
