Snout rather prominent, smooth; rostral small; a large nasal on each side 
‘of rostral meeting behind that shield on the midcephalic line; a pair of 
large praefrontals separating the pair of frontals from the nasals; the 
contour scales extend to these shields, except for several slightly enlarged 
scales which might be considered occipitals. It is not impossible that some 
would consider the scutes here called frontals, as really parietals. Eye 
invisible in a medium-sized ocular; this is bounded anteriorly by the first 
labial (which extends upward to the praefrontal), inferiorly by the third 
labial, and posteriorly by the upper of the two first temporals. These 
two temporals are followed by three smaller ones. There are but three 
supralabials. The infralabials are also three, the second largest. A large 
median chin shield is in contact with the first and second lower labials; 
also a pair of large chin shields are in contact with the second and third 
lower labials and are separated from each other by five other shields 
posterior to the large median chin shield mentioned above. 
One hundred and ninety-one annuli on body; three complete caudal 
annuli anterior to the ring-groove, and ten posterior to it. An annulus 
about the middle of the body contains sixteen dorsal and twenty ventral 
segments, the ventral segments being much larger than the dorsal. The 
pectoral shields consist of about sixteen scutes, four rows of four scales 
each, the two median rows largest. All the scales somewhat irregular in 
shape and position and a few partially fused together. Preanal scales, two 
large in median position, flanked on each side by three smaller scales. 
Color yellowish, in spirits, somewhat darker above than below. 
Among a collection of reptiles made by Dr. Glover M. Allen in 
British East Africa appears a small series of specimens which appar- 
ently represent a new species closely related to Algiroides africanus 
Boulenger (P. Z. S. 1906, p. 570, fig. 96) from Entebbe, Uganda. 
This lizard may be called 
Algiroides alleni sp. nov. 
Type, an adult from near the “tree limit,’”’ northeast slope of Mt. Kenia, 
British East Africa, no. 9280, Mus. Comp. Zodlogy, taken Sept. 9, 1909, 
by Dr. G. M. Allen. There are four paratypes from the same locality. 
This species differs from A. africanus in having much larger, hence fewer, 
gular scales than shown in Boulenger’s figure; in having the collar of four
