the dorsal shields of the neck and body are striated : those on the body 
are also strongly keeled, most pronouncedly so on the two mesial rows 
of scales, which moreover are broader than any of the other dorsal or 
lateral scales. The dorsal shields of the neck are not keeled : most of 
the lateral scales of the neck are striated, but several of those most 
anteriorly situated are entirely smooth or only feebly ribbed. All the 
lateral scales of the body are. striated and keeled. The caudal scales 
are strongly keeled throughout, and the dorsal and dorsolateral scales 
are also striated. The lateral fold is slightly curved in the neck 
region, but straight along the body. The general colour is olive with 
small darker spots on the upper surface of the head. Dark brown 
spots also occur on the posterior borders of the scales of the neck 
superiorly. The temple and side of the neck have dark brown vertical 
bars, which occur on the posterior borders of the scales and extend to 
the scales of the lateral row of the ventral region on each side. 
Subocular shield with dark spots, and dark markings also occur 
along the upper and lateral borders of the upper labials. Ventral 
surfaces Dale. 
Measurements of larger specimens:- — 
Length of head 11 mm. 
Breadth of same 6.2 mm. 
Length of hindlimb 5 mm. 
Distance from snout to vent ... 78.5 mm. 
The tail is reproduced at a point 97 mm. distant from the vent. A 
somewhat smaller specimen with original tail intact has the following 
proportions: — Distance from snout to vent 72 mm., length of tail 
237 mm. 
The two examples show the following differences in head scaling : 
The large specimen has the two frontoparietals meeting in the midline 
and forming a long suture, whereas in the other specimen the two 
frontoparietals are completely separated by a backward prolongation 
of the frontal meeting the interparietal. Description based on two 
specimens kindly lent to me by Mr. F. W. Fitzsimons, the Director of 
the Port Elizabeth Museum. The larger one came from Schoemachers 
Kop, near Port Elizabeth; the other is labelled as from Kroonstad 
(this locality record is, I think, doubtful). 
T etradactylus Fitzsimonsi is the most serpentiform species of the 
genus, and, indeed, of the family. It is closely related to T . africanus, 
Gray, but may be distinguished from that species by the complete 
absence of the forelimbs, at any rate as external structures. 
I may here remark that the description of T. africanus given in 
the British Museum catalogue of lizards, Vol. Ill, p. 125, is apparently 
incorrect in respect to the dorsal scaling, these cited as in 60 to 62 
transverse series: in the only specimen of this species which I have 
been able to examine (from Witzies Hoek, near Harrismith, coll. 
Natal Museum) the number of transverse series is the same as in 
Fitzsimonsi , and all the forms referable to the africanus group, 
including' breyeri Roux and Eastivoodae Hewitt and Methuen, seem to 
be characterized by a greater number of transverse series than occurs 
in Seps L. t etradactylus Lacep or Imevicauda sp. nov. The above- 
mentioned specimen of Africanus differs from Fitzsimonsi in possessing 
a broader interparietal scute and in the absence of dark spots on the 
head as well as in the limb character,
