PISCES.

Onty one species of Fish, the widely distributed Tilapia nilotica, L., was known
from Rnwenzori, where specimens were found, between 5000 and 6000 feet, by
Mr. G. F. Scott Elliot. ‘The same fish was obtained to the S.E., at 3200 feet altitude,
by Mr. R. B. Woosnam, the leader of the present Expedition, Examples of two species
were obtained near Fort Portal, alt. 4500 feet, viz Clarias carsonii Blgr. and Barbus
portali Blgr., the latter being a new species which I have described and figured in the
‘Fishes of the Nile.” From Irumu, in the Congo Forest, alt. 3000 feet, we have
examples of five species: Alestes macrophthalmus Gthr., A. grandisquamis Blgr.,
A. imberi Peters, Barbus holotenia Blgr., and Barilius ubangensis Pellegr. A small
collection made in the Aruwimi River contains representatives of ten species :
Pellonula obtusirostris Blgr., Bryconethiops microstoma Gthr., Petersius woosnami Blgr.,
Micralestes acutidens Peters, Labeo parvus Blgr., Barilius ubangensis Pellegr.,
Chelethiops elongatus Blgr., Eutropius grenfelli Blgr., Synodontis greshoffi Schilth.,
and Mastacembelus congicus Bigr.

Pellonula obtusirostris and Petersius woosnami have been described and figured in
the first volume of the British Museum Catalogue of African Fresh-water Fishes.

Described from five specimens obtained near Fort Portal, 12 miles east of Ruwenzon,
at an altitude of 4500 feet, in a small stream, a tributary of the Mpanga, flowing into
Lake George.

Mr. Woosnam observes that this was a common fish in the eastern streams of

Ruwenzori, which it probably ascends from Lake George. It was not met with
above 5000 feet.

This is a little-known species. It was described by me (Ann. & Mag. N. H. (6)
xviii. 1896, p. 467) from specimens obtained in Lake Tanganyika by Mr. W. Nutt,
and the British Museum has since received specimens from various parts of British
Kast Africa. Specimens from Kilimanjaro have been referred by Tornier (Kriechth,
Deutsch-Ost-Afr. p. 92, 1897) to R. bravana Peters, which species I regard as
identical with 2. galamensis D. & B.

G. A. BOULENGER—REPTILIA. 241

The following description is taken from the Ruwenzori specimens :—

Vomerine teeth in two strong, slightly oblique series between the choane. Head as
long as broad, or a little longer than broad; snout rounded, scarcely projecting,
slightly longer than the diameter of the orbit ; canthus rostralis obtuse ; loreal region
very oblique and slightly concave; nostril equally distant from the eye and from the tip
of the snout, or a little nearer the former; interorbital space a little narrower than the
upper eyelid ; tympanum very distinct, two-thirds to three-fourths the diameter of the
eye. Fingers obtusely pointed, first and second equal; toes slender, obtusely pointed,
two-thirds webbed; subarticular tubercles small; a small elliptical inner metatarsal
tubercle, measuring one-third the length of the inner toe. ‘Tibia as long as or a little
longer than the fore limb, as long as the foot; tibio-tarsal articulation reaching the tip
of the snout or beyond. Skin smooth; a narrow but very prominent glandular dorso-
lateral fold from the upper eyelid to the sacral region. Greyish or olive-brown above,
with more or less distinct darker spots; a broad, light, dark-edged vertebral band some-
times present; a dark streak from the end of the snout, through the nostril, to the eye;
a dark temporal spot ; a light streak from below the eye to the angle of the mouth;
limbs with dark cross-bands ; lower parts white, throat with brownish marblings.

The largest specimen measures 64 mm. from snout to vent.

Rana nutti is very nearly related to R. angolensis Bocage.

Two female specimens, showing variations in the markings, are figured on

Plate VIII. figs. 1 & 2.

REPTILIA.

The species of Lizards obtained on Ruwenzori by Mr. Woosnam are Agama atricollis,
A. Smith, Lacerta jacksonii Blegr., Mabuia maculilabris Hallow., Mabuia striata Peters,
and the undescribed Lygosoma for which I proposed the name L. meleagris. This is
here redescribed and figured, and I have appended notes on the specimen of the little-
known Lacerta jacksoni.

Chameleons are represented by Chameleon senegalensis Daud. (/evigatus Gray) and
C. ellioti Gthr., obtained at the foot of the mountain (5000-6000 feet) by Mr. G. F.
Scott Elliot; C. johnstoni Blgr., and C. xenorhinus Blgr., two remarkable forms
discovered by Sir H. H. Johnston, and of which further examples were collected
during the Expedition; and a small species, C. rudis Blgr., of which a female had
been previously obtained by Sir H. H. Johnston, but which could not be properly
understood until the male was discovered by Mr. Woosnam and his party.

Of Snakes, Leptodira hotambeia Laur. and Elapechis guentheri Bocage were brought
home from the foot of Ruwenzori by Mr. G. F. Scott Elliot ; Chlorophis emini Gthr.

2. Lacerta JAcKsonI Bler.

Bouleng. Proc. Zool. Soc. 1899, p. 96, pl. x.

‘This species was described from a single male specimen procured at Ravine Station,
Mau Mountains, on the main route from Mombasa to Lake Victoria, at an altitude
of 7500 feet. Ji was presented to the British Museum by Mr. F. J. Jackson. A
second specimen, a female, was obtained by the Expedition, on the east side of
Ruwenzori, at a height of 8500 feet, on the trunk of a tree.

The head is smaller and shorter than in the type, and the body more elongate,
these differences being sexual. ‘The granules between the supraoculars and the super-
ciliaries are reduced to three on the right side and to two on the left ; the occipital is
much shorter and a little broader than the interparietal; on the left side the parietal
is in contact with the fourth supraocular and the upper postocular, on the right side
with the fourth supraocular only. ‘The dorsal scales are very faintly keeled ; 37 scales
across the middle of the body; 27 transverse series of ventral plates. The hind limb
barely reaches the axil. Femoral pores 18-19. The belly, in the spirit-specimen,
is pale blue.

Measurements :—

From end of snout to vent 71 mm.; head 17; width of head 11; fore limb 25;

hind limb 36.

Judging from the description, I am in doubt as to Tornier’s L. vawereselli (Zool. Anz.
1902, p. 701) being specifically distinguishable from L. jacksont. The temporal scales,
perfectly smooth in the Ruwenzori specimen, are feebly keeled in the type. The
statement “ Nur 8 Femoraiporen an jeder Seite” (p. 702) is contradicted further down

(p. 703), “ Femoralporen 16 an jeder Seite.”

Body much elongate ; limbs small, with four very short digits; the distance between
the end of the snout and the fore limb is contained twice and a half in the distance
between axilla and groin. Snout very short, obtuse; lower eyelid scaly; nostril
pierced between two nasals; no supranasal; fronto-nasal broader than long, broadly
in contact with the rostral and with the frontal; prefrontals minute ; frontal not much
larger than fronto-parietals, in contact with the first and second supraoculars ; four
supraoculars ; five supraciliaries ; fronto-parietals distinct, larger than the interparietal ;
parietals forming a suture behind the interparietal; a pair of nuchals; fourth upper
labial below the centre of the eye. Ear-opening minute, about as large as the nostril.
22 smooth scales round the middle of the body. Median preanals scarcely enlarged.
The length of the hind limb equals the distance between the anterior border of the eye
and the fore limb; second and third toes (normally third and fourth, the hallux being
absent) equal, with 12 lamelle inferiorly. Tail long and thick. Upper surface of
head and back blackish-brown, with small round white spots; sides of body, belly,
hind limbs, and base of tail uniform orange; a black streak on the temple and along
the side of the neck ; throat black ; greater part of tail brown above and white beneath,

[These Chameleons were numerous on the lower slopes of Ruwenzori from 5000 to
6000 ft., especially among the rough scrubby vegetation which springs up on the sites
of old cultivations. None was obtained or seen above 6000 ft.—k. B. W.]

8. CHAMALEON RUDIS Blgr. (Plate VIII. figs. 5, 5a, 6.)

Head short, the casque feebly raised posteriorly, with feeble, tubercular parietal
crest ; the distance between the commissure of the mouth and the extremity of the
casque equals the length of the mouth; no rostral appendages ; lateral crest merely
indicated ; no trace of occipital lobes; 10 scales across the interorbital space. Body
covered with large, very convex granules of irregular size, intermixed with still larger
ones, some of which are arranged in a dorso-lateral series; a dorsal crest of conical
tubercles, the largest of which alternate with one or two smaller ones; a series of long,
conical, spine-like tubercles forms an uninterrupted gular-ventral crest, the longest
tubercles, on the throat, measuring half the diameter of the orbit. No tarsal process.
Tail as long as or a little shorter than head and body, crested like the back. Male
dark olive-grey, female nearly black, with some of the larger tubercles on the body

G. A. BOULENGER—REPTILIA. 245

A single specimen, a gravid female, of this small Chameleon was presented by
Sir H. H. Johnston to the British Museum in 1901. I had referred it provisionally to
C. biteniatus Fisch., from which it differs in the coarser scaling and in the much
longer spine-like tubercles forming the gular-ventral crest, and it was briefly alluded
to by Mr. J. L. Monk (‘Zoologist,’ 1903, p. 324) as likely to prove a new species, a view
which is confirmed by the discovery of the male by the Ruwenzori Expedition, in the
Mubuku Valley, on the east side of the mountain, at an altitude of 10,000 feet.

[A specimen (no. 24, 2nd Feb., 1906) was found at 10,000 ft., just where the bamboo
and tree-heath zones meet and intermingle, forming rather more open patchy country.
This specimen was much smaller than the C. ellioti met with lower down and of a dirty
grey-green colour. At this altitude (10,000 ft.) the vegetation was sometimes white
with frost in the early morning. During the time we were encamped there the native
porters (about 20 in number) were offered rewards for finding Chameleons, but they
never found but this one, which was sitting on a rotten stump of tree-heath. I fully
expected this alpine Chameleon to be of a different species to C. ellioti, which is met
with below 6000 ft., where the climate is hot and tropical—R. B. W.]

Those who regard C. elliott and C. hoehnelii as races or local varieties of C. biteniatus
would of course place C. rudis under the same species—and I should be the last to
blame them, having at one time held the same opinion.

9. CHAMALEON JOHNSTONI Bler.

[This Chameleon was obtained only in the Mubuku Valley, E. Ruwenzori, between
6000 and 7000 feet, and it did not appear to be very plentiful. It is found usually
among the lower bushes and shrubs just below the forest-line, or in the open spaces
where native clearings had been made just inside the forest.—R. B. W.]

10. CHAMHLEON XENORHINUS Bler.

[This Chameleon was obtained only in the Mubuku Valley, E. Ruwenzori, from
6000 to 7000 feet, and was found in much the same kind of situations as C. johnstoni,
but it appeared to be more partial to the larger trees and was found upon the trunks.
We noticed, too, that this Chameleon when first caught was always of a much darker
colour than (. johnstoni, almost black, and never became very much lighter. It is not
improbable that it lives in the large forest-trees, where its presence would be almost
impossible to detect.—R. B. W.]

13. ATHERIS woosNAMI Blgr. (Plate IX.)
Bouleng. Ann. & Mag. N. H. (7) xviii. 1906, p. 37.

In shape the head resembles that of Vipera berus, being more clongate than in the
other species of Atheris, truncate at the end, and provided with a sharp canthus
rostralis; the eye is rather small, its diameter about half the length of the snout in
the adult. The end of the snout below the canthus rostralis and between the nasal
and first labial shields is covered by four smooth shields: a rostral, which is twice and
a half to three times as broad as deep, and above it three shields in a row, the median
of which may be regarded as detached from a rostral such as exists in a typical Viper.
The scales on the snout and vertex may be smooth or more or less strongly keeled,
further back they are all strongly keeled ; there are 8 to 10 across the crown from eye
to eye and 12 to 15 round the eye, which is separated from the upper labials by one
or two series of scales; the upper labials number 10 on each side ; there are 3 or 4
pairs of small chin-shields, the anterior largest and in contact with 5 or 4 lower labials;
unlike those of the other Atheris, the gular scales are smooth or very faintly keeled.
The highest number of scales across the body varies between 25 and 30; all are
strongly keeled. Ventrals 151 in males, 158 to 162 in females; anal entire ; sub-
caudals 49 to 52 in males, 44 to 47 in females *.

In coloration as well as in form and scaling this Atheris departs less than its con-
eeners from the typical Viper pattern, the characteristic zigzag dorsal band and the
reversed initial (W) on the head being present in some specimens. The ground-colour
varies from olive-green to bright grass-green above, from yellowish to pale green
beneath ; the keels of most of the scales are black, and the upper head-scales are edged
with black ; there is usually a dorsal series of large black rhombs, which may be con-
fluent into a zigzag band, and a lateral series of smaller black spots; a A- or A-shaped
black marking on the top of the head, the apex between the eyes; a black streak on

* In the large series of Atheris chloroechis and A. sguamiger in the British Museum, which renders the
distinction of these two supposed species an almost impossible task, the variation in the number of ventrals
ranges between 145 and 165 for males, 152 and 176 for females, and that of subeaudals between 52 and 65 for
males, 46 and 59 for females.

each side of the head, from above the nostril to above the last labial shield ; the end
of the tail is black or blackish.

The largest specimen measures 630 mm., in which the tail enters for 85.

[Several specimens of this very distinct species were obtained in the Mubuku Valley,
E. Ruwenzori, between 6000 and 6500 fect altitude.

This fine Snake may sometimes be seen coiled up round the stem of elephant-grass
10 feet above the ground, One cf the specimens contains embryos.—L. B. W.]
