On anew Typhlops from Tanganyika Territory. 685 
have a general arrangement resembling that of G. connor- 
filii ; the prebursal papille are small. ‘he equal and similar 
spicules measuring O°4 produce together a lyrate appearance 
at their points when seen from dorsum or venter. The length 
of the accessory piece is 0°055. 
The female has a length of 5°25 and a maximum breadth 
about the equator of 0°35. ‘The distances between the anterior 
end and the cervical papilla, nerve-ring, excretory pore, and 
cesophageal termination are respectively 0°45, 0°4, 0°425, and 
0-75. The vulva lies 2 from the tip of the caudal mucron. 
The intra-uterine ova measure 0065 to 0°07 by 0-04. 
LXXXVIIL—Description of a new Typhlops from 
Tanganyika Territory. By JOAN B. Procrer, F.Z.S. 
Typhlops excentricus, sp. u. 
Diagnosis.—Closely allied to T. mucroso, Ptrs., from which 
it may be distinguished by the shape of the rostral (which is 
truncated instead of rounded posteriorly), by the nasals (which 
meet each other behind the rostral), and by the comparative 
slenderness of its body (which is 44 times its diameter as 
against 35). It also differs from the typical mueroso in 
having the lower surfaces finely variegated, as in the form 
described as 7. humbo by Bocage. 
Description.—Head strongly depressed, ornamented above 
and beneath with minute excrescences disposed thickly at 
regular intervals. Snout with sharp cutting-edge, flat 
beneath and projecting to a distance equal to half length of 
head. 
Rostral small, not extending nearly to level of eyes; 
portion on upper surface of head squarish, portion beneath 
snout triangular, equilateral. Nostrils inferior ; nasals semi- 
divided, the cleft extending from first labial, meeting each 
other above by a short suture behind rostral ; preoculars 
about two-thirds breadth of oculars, pointed above and 
beneath ; eyes distinguishable, superior ; oculars separated 
from each other by three scales; mouth minute. 
Body with 30 scales round the middle, depressed *, its total 
length about 44 times its diameter. Tail broader than long, 
ending in a spine. 
* The sloughed skin shows that the depression of the body is to some 
extent natural, and not due to distortion on preservation.
