river must have been very much bigger/at soma d^ta\or(jtee &
it had altered its course. The preseri|^ctMPriVer-bea is y
well defined, but on either side for some di^ance up to a quarter^ /
of a mile there is heavy sand, as if deposited^W^^c^to^^l^’,,'
the water, and then there is a bank of about 6 feet Ub’Tothe
stone and shingle.
The present actual bed of the river winds about from side
to side of this greater valley. The same applies to the Turk-
well, only in a greater degree.
The next stage of the journey takes us to Kobua River at
Rudolph. The camping grounds are Skull Camp, Lodwar,
Kobua waterholes, and then on to Rudolph, about 61 miles.
The first two stages to Lodwar follow the Turkwell. Water
is obtained by digging in the river-bed if the river is not
running. Along the Turkwell there is a thick fringe of timber
and scrub, and the country is sandy. Away from the river
the country is all rough stony plain, covered with horrible
thorny bush.
There is a fine outcrop of hill at Lodwar, running north-west
and parallel to another river called the Kagwalla, this river
rising on the north side of the Murissica Mountains. The pro-
minent peak of this range is an important landmark and when
climbing it appears to be nothing but a heap of volcanic shingle.
From Meuressi to Lodwar the Turkwell runs practically north,
but at Lodwar it takes a bend round to east and follows this
general direction right on to Rudolph.
The Turkana in this district were aggressive and attacked
a small patrol of Askaris one night. They didn’t count on
the sentry being awake ! When he fired at them he killed
two with one shot. The skulls of these two Turkana adorn
the outskirts of the camp and give to it the name Skull Camp.
At Lodwar we leave the Turkwell and take to the desert
track which runs to Kobua waterholes. This is a long water-
less track and very hot, so we started at four in the afternoon
and travelled all night, reaching the waterholes next morning.

ON A COLLECTION OF BIRDS
The country is flat stony plain, covered with the eternal thorn
bush.
Just a few miles before the waterholes we entered a low
range of hills, running north and south, which extend from the
Turkwell on the south up to the Labur Mountains, a distance
of about 100 miles. Along the road they are about 8 miles
wide.
The general direction Lodwar to Kobua waterholes is
north-east. Kobua waterholes to Kobua River north-east by
east.
The next morning we marched into Kobua Camp, which
was at that time the headquarters of the Force. The scenery
round the shore is improved by the presence of stately Dom
palms, but farther back from the lake the same thick scrub
and thorn bush is in evidence.
The soil here is sandy and covered with large numbers of
shells, indicating that Rudolph must have covered this area
at some remote time.
The great attraction at Kobua Camp is naturally the lake.
We could not take our eyes off the beautiful expanse of blue
water, especially after the country we had come through ;
and the breeze — well, I can only leave the reader to imagine
it !
Upon our arrival we interrupted a battle royal between
a scorpion and a tarantula. We found all the European
officers, except those on patrol duty, standing open-mouthed
watching this. One stout civil official acted as bookmaker,
and bets on the issue were flying around.
I think the picture I have painted of Turkanaland is pretty
black, but to kill any doubts let me mention a few of the vermin.
Scorpions there are in thousands, some black, others brown,
of huge size, and these secrete themselves under boxes and
such like and woe betide the unfortunate individual who goes
to lift the box. Nearly all the officers were bitten at one time
or another.
The largest centipede I ever saw was here. Tarantulas
abound among the palms and hold their nightly ngomas.
The one redeeming feature of Turkanaland is Lake Rudolph.
It is not like other lakes in East Africa. Here are beautiful

sandy beaches, most perfect for bathing, despite the crocodiles.
Bird-life teems ; duck, pelicans, egret, and flamingo exist in
countless numbers. I once saw 40 acres covered by pelicans
as close as they could sit.
The reader will see from this introduction that the collection
of birds comes from a district practically unexplored, and only
just opened up by the military operations, and will realise
the difficulties which had to be contended with in getting
together such a remarkably interesting series.

It is evident, then, that the case is pretty well made out
for the Herbivora demanding a larger supply of sodium salts.
I gather that there are no ‘ salt-licks ’ in the country in which
the Lumbwa Cave is situated. Hence the avidity with which
the cattle consume the relatively sodium-rich material.
There is, however, one difficulty in this explanation. I
understand that animals become excited and anxious to get
to the cave a long way off. This is suggestive of an odour,
and sodium salts are, so far as I know, devoid of smell. Hence
the animal does not get excited about the sodium.
I do not think it likely that the material is consumed as
an antacid. Nor, as the animals are Herbivora, and pre-
sumably consume large quantities of cellulose, do I think
that the material is ingested as intestinal ballast for irritative
purposes. On the other hand, the suggestion that its con-
sumption has something to do with ‘ discouraging intestinal
parasites ’ is extremely interesting, and may be well worth
following up. We know practically nothing about the influence
of the environment on the growth of intestinal parasites of
any kind.

ON PHYTOPHAGOUS COLEOPTERA OF THE FAMILY
CHR YS OMELIDiE
By A. F. J. Gedye, F.E.S., Curator of the Nairobi
Museum
Introduction
The Phytophaga form an extensive group of beetles, in-
cluding something like 40,000 species ; this, however, must be
only a small portion of those existing on the globe.
The term Phytophaga is restricted by many taxonomists
to the Chrysomelidce, but in the opinion of the majority it is
impossible to satisfactorily separate the Longicornia from
the group. The Lariidce (Bruchidce) are also considered,
by some, to form a family of Phytophaga, but a study of the
nervous system shows it to be more concentrated and al-
together more highly specialised than that of the other families
of Phytophaga. From these considerations it is perhaps
advisable to place the Lariidce in the Bhynchophora, whose
internal morphology is apparently of a more recent and
advanced type.
As before stated, the two families of Longicornia cannot
be separated from the Chrysomelidce on any definite characters,
although an acquaintance with the general facies of the families
would, in most cases, prove sufficient for mere differentiation.
Jacoby (‘Fauna Brit. Ind.: Coleoptera,’ II, 1908, p. 3)
states that usually, in the Longicornia, ‘ the shape is very
elongate, the head projecting and prominent, the eyes oblique
and more or less divided, and the antennae peduncular, these
organs at the same time rigid and tapering at the apex. All
these structures are not as a rule found in the Chrysomelidce.’
We will therefore consider here the Phytophaga as con-
taining three families which may be distinguished, according
to Fowler,1 as follows : —
1 Fowler, Fauna Brit. Ind., Gen. Introd., p. 177.

ON PHYTOPHAGOUS COLEOPTEEA
I. Antennae short or moderate, not in-
serted on frontal prominences ;
tibial spurs usually absent .
Chrysomelid^l
II. Antennae usually long or very long,
frequently inserted on frontal
prominences ; tibial spurs distinct.
(a) Head in front oblique or
subvertical
Cerambycid^ej.
(b) Head in front vertical or
bent inwards below the
thorax
Lamiid.®.
It is proposed, in the present paper, to consider the Chryso-
melidce, with general remarks on their habits, structure, and
classification, and any notes, that are known or available to
the writer, with reference to their occurrence in East Africa
and Uganda.
Form variable ; head prominent or moderately, so, and
inserted in the pronotum as far as the eyes ; antennae
moderately long, variable in shape and insertion, usually
eleven- jointed and moniliform (shaped as if formed by beads) ;
pronotum with or without lateral margins ; elytra usually
covering abdomen, but sometimes leaving the pygidium
exposed, upper surface usually bare, often brightly coloured
and metallic ; legs variable, tarsi pseudotetramerous.
The Chrysomelidce form an enormous family of over 20,000
known species, and it is probable that, when the family has
been thoroughly worked in the tropics, the above number
will not form a fifth of the total existing species.
The beetles are, without exception, plant- feeders both in
the larval and perfect states. Many of the species are of
considerable economic importance as pests of cultivated trees
and shrubs. A notable instance is that of the Colorado
Potato Beetle ( Doryphora decemlineata) , which caused so much
destruction in North America some years ago.
Chrysomelidce can best be captured by beating trees and

bushes into a net or umbrella, and by sweeping grasses and
any kind of herbage ; damp vegetation near the banks of
streams being particularly productive.
Very little is known of the life history of the family ;
altogether about 100 species have been worked out, most
of these being European. The special modifications of
the different larvae and pupae will be alluded to under the
different families. The following table of larvae is that
given by Chapuis (‘ Genres des Coleopteres, Suites a Buffon,’
X, 1874, p. 15), with alterations by Sharp (‘ Cambridge
Nat. Hist.,’ Vol. VI, p. 279), and quoted by Fowler (op.
cit., p. 182).
I. Larvae with the body uncovered.
A. Larvae elongate, subcylin-
drical, whitish, living on or
in the stems of aquatic
plants under water ; pupae
also subaquatic, contained
in cocoons fixed to the
roots of the plants . . Donaciin-e.
B. Larvae mining, more or less
elongate, sublinear or nar-
rowed at each end, under-
going their metamorphoses
on the plants . . . HiSPiNiE and some
Halticin^j.
<7. Larvae short, oval, very con-
vex above, often more or
less brightly coloured, or
dark metallic, living ex-
posed on the plants and
undergoing their meta-
morphoses on the plants or
in the ground . . . Cyclica (most).
II. Larvae with the body protected by
excrement.
A. Larvae short, oval, very con-
vex above, dark coloured,

ON PHYTOPHAGOUS COLEOPTERA
without any special appar-
atus for carrying the excre-
mentitious matter, under-
going their metamorphoses
in the ground . . . Criocerin^e
(in part).
B. Larvae short, oval, somewhat
depressed, spiny, with the
excrement supported and
attached by a special appar-
atus, undergoing their meta-
morphoses on the leaves . Cassidinje.
III. Larvae elongate and whitish, with
the abdomen curved, inhabit-
ing portable tubes or cases
and undergoing their metamor-
phoses in these . . . Clythrin^ (and
most Camptosomes).
The classification of the perfect insects is but little advanced
in spite of the large number of forms which have been described.
The best arrangement, however, is perhaps that adopted by
Jacoby (op. cit., p. 3).
I. Mouth placed anteriorly.
A. Antennae widely separated at
base ; elytra of hard texture,
intermediate ventral segments
not medially constricted ;
pvgidium not exposed.
(a) Thorax without distinct
lateral margins, head
produced, eyes promi-
nent, prosternum exceed-
ingly narrow . . Eupodes.
( b ) Thorax with distinct lateral
margins (rarely without),
head not produced, eyes
not prominent, proster-
num broad . . Cyclica.

intermediate ventral segments
constricted; pygidium
usually exposed
Camptosomes.
B. Antennae not widely separated
at base, generally closely
approximate ; elytra more
or less soft in texture
Trichostomes.
II. Mouth not normal, small, hidden
or nearly so
Cryptostomes.
Although the distinguishing features in the above table
between the different groups may not in all cases appear
very clear, it may be remarked that a practical acquaintance
with a few selected types will, in nearly all cases, enable the
beginner to relegate his species to the different groups.
Unfortunately all the literature on East African Chryso -
melidce that has appeared is widely scattered in odd papers
in various publications. However, a fair number are described
by Kolbe in ‘ Deutsch-Ostafrika : Thierreich,’ by Jacoby
in the Proc. Zool. Soc., and by Weise in various German
publications.
I may add that I shall be delighted to give what help I can
to any members of the Society who feel inclined to take up
the study of this fascinating group of beetles.
This division of Chrysomelidce contains three sub- families :
Sagrince, Donaciince, and Criocerince. The Donaciince are
remarkable on account of living a semi- aquatic existence,
wholly aquatic in the case of the larvae. The sub- family,
however, is characteristic of the temperate zone, and I can
find no record of its occurrence in Eastern Africa.
The Sagrince and Criocerince are, however, represented
in our region, and may be roughly distinguished as follows : —
I. Size large ; posterior femora strongly
thickened ..... S ageing.
II. Size small ; posterior femora not
strongly thickened . . . Criocerin^.
Division I. Eupodes
8
ON PHYTOPHAGOUS COLEOPTEEA
The Sagrince are moderately large insects, often brightly
metallic, with strongly dilated posterior femora. It appears
that the use of the latter organs is not for saltatorial purposes,
as the insects are frequently found suspended from stems and
branches, head downwards, and supported by the hinder
femora. Species of Sagra are common on the west coast of
Africa, and I have taken a bright purple species in Natal,
but few seem to be recorded from our territory. A variety
of Sagra murrayi, Baly, is recorded by Kolbe 1 from Tan-
ganyika Territory, and from Ruwenzori by Gahan,2 and the
Nairobi Museum possesses a brown, slightly metallic species
from Ruiru.
The Criocerince, however, are largely represented in East
Africa and Uganda, most of the species belonging to the great
genus Lema, which contains over 800 species, occurring in
most parts of the world. They are small, brightly coloured
beetles, of hard integument, usually to be found in damp
places.
In the collection of Coleoptera in the Nairobi Museum there
are five or six unidentified species of Lema from various parts
of Kenya Colony ; there is also a specimen of Lema chalcojptera,
Lac, a small, brightly metallic aeneous species from Tanganyika
Territory.
Some of the larvae of the genus Crioceris have the power of
covering themselves entirely with excrement, which, however,
can be cast off at will. According to Sharp (‘ Cambridge Nat.
Hist.,’ Vol. YI, p. 281), some of the imagines have the power
of stridulating by means of two contiguous areas situated
on the last dorsal segment of the abdomen.
Division II. Camptosomes
This division is remarkable on account of the peculiar
structure of the abdomen, which appears to be connected
with the habit of forming a case to envelop the egg.
The division contains six sub- families — viz., Megascelince,
Megalopince, Clythrince, Cryptocephalince , Chlamyince, and
1 Deutsch-OstafriJca, IV, e Coleoptera,’ p. 325.
2 Trans. Zool. Soc Vol. XIX, pt. ii, p. 216.
OF THE FAMILY CHRYSOMELIDiE

Sphaerocarince. We will here consider only the Clythrince and
Cryptocephalince, as they are best represented in our region.
They may be roughly distinguished as follows : —
I. Form more elongate, less convex ;
rarely metallic and iridescent ;
eyes inserted higher on head . Clythrin^j.
II. Form less elongate, more convex ;
often metallic and iridescent ;
eyes inserted lower on head . Cryptocephalinje.
The Clythrince are often moderately large insects decorated
with conspicuous spots and stripes on a lighter background,
and can be sometimes beaten from trees in the vicinity of
ants’ nests.
The beetles comprising the sub- family Cryptocephalince
are often of great beauty, and when seen in the net give
one the impression of ‘ living jewels.’ They are exceedingly
wary, and often the least sound will cause them to drop from
trees and bushes into the long grass, rendering further
search futile. Cryptocephaline larvae are, according to Weise,1
most remarkable ; they inhabit portable cases with the
abdomen curled against the sternum. They can only emerge
from the cylindrical case as far as the first abdominal segment,
and, in consequence, progress with a curious jerky motion.
A pretty little Cryptocephalus has recently been taken by the
Rev. K. St. Aubyn Rogers at Sagalla, and presented by him
to the Nairobi Museum.
Division III. Cyclica
To this division belong the mass of the Chrysomelidce ; the
species are most permanently brilliant in their colours, although
they are surpassed in life by some of the Cassidinoe. Three
sub- families are contained in this group — viz., Lamprosomince,
Eumolphince, and Chrysomelince.
Some of the Chrysomelince are serious pests of vegetation,
such as Doryphora ( Leptinotarsa ) decemlineata, before mentioned,
also the common ‘ Mustard Beetle ’ ( Phaedon cochlearice) ;
1 Weise, Naturg. Ins. Deutsch., VI, p. 139.
10
ON PHYTOPHAGOUS COLEOPTERA
the larvae are, however, in many cases kept down by parasitic
Hymenoptera of the family Braconidce.
The Lamyrosomince are not, I believe, represented in our
fauna. The Eumolphince and Chrysomelince may be separated
as follows : —
I. Form more elongate, less convex ;
pronotum narrower ; mandibles
vertical or sub- vertical . . EuMOLPHiNiE.
II. Form ovate, very convex ; pronotum
broader ; mandibles rarely vertical
or sub- vertical .... Chrysomblin^j.
The Eumol'phince constitute a large sub- family of very
brilliant species ; there is a large amount of individual variation
amongst its members, one species sometimes being represented
in blue, green, red, gold, and all the intermediate shades.
The sub- family is well represented in East Africa and Uganda,
although the family is very little worked, and there is no
doubt that a large number of new species will yet have to be
described. One of the most beautiful genera is Corynodes ;
they love damp places, and I recently took a fine species
by the side of a stream on the road between Kampala and
Entebbe. Some species affect trees in drier situations, and I
recently beat a large number of a pretty red and black species
from acacia trees at Thika, near Nairobi. When discovered
they are by no means agile, and affect death, although their
coloration is so conspicuous that any chance of escape is
slight.
The beetles comprising the sub- family Chrysomelince are
typical Chrysomelids, and very numerous in practically all
parts of the globe. In many cases different species are severely
attached to distinct plants, and to be found must be searched
for in their various habitats. I was once collecting at
Kimberley, South Africa, in a field in which there were perhaps
six species of plants in great abundance growing round a dried-
up ‘ vlei * ; five of these plants harboured, respectively, the
same number of Chrysomelince, and in no cases were they
found to be infringing on each other’s habitat.
The Chrysomeline larvae feed in most cases on the plant
OF THE FAMILY CHRYSOMELIDiE
11
which the adult frequents; they are very sluggish in their
movements, and are generally of a pale and insipid colour.
The genus Plagiodera appears to be moderately common
in our region. Several species are recorded by Gahan (op. cit.,
p. 217) from the western portion of Uganda; these are,
however, probably absent from Kenya Colony, as it is a well-
known fact that the fauna of Uganda bears a closer relation-
ship to that of West Africa than to the eastern portion of
the continent. The Nairobi Museum possesses examples of
Plagiodera egregia, Gerst., from Kilindi in Tanganyika Territory.
Ceralces is a rather inconspicuous genus of itinerant species
occurring throughout our region. The Museum possesses
specimens of Ceralces natalensis, Baly, from Dar-es- Salaam.
This species (as its name implies) was originally recorded from
Natal, and it will be found that there is a marked similarity
between the coastal faunae of the whole of the East African
coast.
Division IY. Trichostomes
The Trichostomes include a vast assemblage of smaller forms
comprised by two sub- families, the Galerucince and Halticince.
Although these two sub- families differ rather greatly in external
form, they have several characters in common.
I. Exo- skeleton softer; legs slender,
weaker, and feebler, and not
adapted for jumping . . . Galerucin^b.
II. Exo- skeleton harder ; legs shorter,
stouter, and adapted for jumping,
posterior femora visibly dilated . Halticin^.
The Galerucince are probably the most abundant group
of the Chrysomelidce, and generally form a feature of the
contents of the sweeping net. It may be well to remark here
that it is always advisable to examine the contents of one’s
net, if possible, in the shade, as the beetles do not then so
readily take to the wing or make use of their saltatorial powers ;
this applies not only to the Chrysomelidce, but to other families
of Coleoptera, particularly to the Malacoderms and arboreal
Heteromera.
12
ON PHYTOPHAGOUS COLEOPTERA
The Galerucince are well represented in East Africa and
Uganda, and much work remains to be done amongst the
group.
Among four species of Galerucince submitted to the British
Museum by Sir Harry Johnston, Gahan records two as new
to science (Johnston’s ‘ Uganda Protectorate,’ Yol. I, p. 464).
The sub- family is also of economic importance, and Idacantha
magna, Weise, is recorded by Dr. Aulmann 1 as a serious pest
of coffee in Tanganyika Territory. Out of fourteen Galerucince
captured by the Zoological Expedition to Ruwenzori, Dr. C. J.
Gahan describes no less than eight as new.2 This affords another
striking proof of how abundant Galerucince are, and of the
extreme probability that many new forms will yet be dis-
covered by means of careful collecting. Many Galerucine
Coleoptera are of dull and inconspicuous coloration. The
genera Oides and Cerochroa are notable in this respect, and
females may often be taken with their abdomens enormously
distended by eggs ; when in this condition they are very clumsy
in their movements, and make no effective effort to escape.
A very beautiful little Galerucine occurs around Nairobi which
might be almost considered the national beetle of Belgium.
The head and legs are a pale testaceous, while the elytra
consist of three transverse fasciae alternating in black, red,
and yellow. Agelastica is a genus of rather uninteresting
beetles of an obscure appearance; they are not uncommon
in East Africa in damp places. Monolejpta is a very large
genus of small, prettily variegated species occurring throughout
Africa ; M. leuce, Weise, and M. lineata, Karsch., are to be
taken with ease around Nairobi. Once while sweeping Com-
posite plants at Kampala, Uganda, I was astonished to note
that at every sweep myriads of small yellow beetles flew from
my net ; on examination they proved to be small Galerucince
of the genus Hyperacantha.
The Halticince are a most interesting sub- family of small
beetles gifted with extraordinary (for their size) powers of
leaping, of which they do not hesitate to make use. They are

exceedingly common in onr region, and may be taken at almost
every movement of the net.1 The ancient genus Haltica of
Linnaeus seems to have a worldwide distribution, and can
be taken in profusion by the sides of East African streams.
They are very variable, and are of some importance in the
study of variation. The Nairobi Museum possesses some
interesting series of Haltica oleracea , L. : a large number of
specimens from Ruiru are, without exception, of a mauve
colour ; specimens from the Karura Forest, Nairobi, are
totally greenish ; while I have taken specimens at the Nairobi
River of two aberrations — viz., a distinct cyaneous blue and of
a reddish purple. As an instance of the wide distribution of
this species I may mention that I have taken it commonly
in various localities in the south of England ; also in eight
widely separated localities in South Africa. A thorough study
of this remarkable little species would probably be of interest.
Many of the sub- family are of an obscure testaceous colour;
the Museum possesses specimens of AjpJithona marshalli, Jac.,
a minute yellow beetle, from ‘ German ’ East Africa. One or
two African genera are large and conspicuous, notably the
genus Podagrica, which contains rather large species of hard
and compact integument, usually variegated with black spots
or stripes on a yellow background. This genus is widely
distributed in Africa, and the Museum possesses specimens
from Sagalla, and I have taken the species commonly at
Isipingo in Natal.2 Regarding the economic side of the family,
the dreaded ‘ Turnip Flea ’ ( Phyllotreta ) belongs to this group,
and many others which have not received such euphonious
appellations as the former name.
Division Y. Cryptostomes
This division contains some very peculiar beetles, on account
of the extraordinary structure of the exo- skeleton. It is the
smallest division of the Chrysomelidce, and the two sub- families,

Halticince, however common, in any number. The Museum will also be
pleased to receive other Chrysomelidce.

the Hispince and the Cassidince, may be distinguished as
follows : —
I. Eorm oblong or elongate ; head not
covered by pronotum ; elytra
usually armed with spines, or the
dorsal surface is at least rugose . Hispin^i.
II. Form ovate or hemispherical ; head
always covered by pronotum ;
elytra not armed with spines,
elytral epipleurse strongly ex-
panded ..... Cassidince.
The Hispince are a small and remarkable sub- family ; the
greater portion of the species belong to the genus Hispa, the
members of which are armed with often long and curious
elytral spines. The antennae are inserted very closely to-
gether, and the tarsal claws are very short. Very little is
known of Hispine larvae or of the complete metamorphosis ;
Perris (Ann. Soc. Liege, X, 1855, p. 260) has worked out the
life- history of the single European species, Hispa testacea.
The larvae feed on the parenchyma of the leaves of Cistus
salvifolius, and they only rupture the epidermis of the leaves
when wishing to remove to a fresh habitat. The habits of
some of the large exotic species are probably very different,
and, unfortunately, nothing appears to be known as yet,
although the recently published volume of Maulik (‘ Fauna
Brit. Ind. : Cassidinae and Hispinae ’) may contain some
fresh data^ Species of Hispa occur freely near Nairobi, in the
Ngong Forest, and in other parts of East Africa and Uganda.
I have recently taken a beautiful blue metallic species, armed
with long black spines, from reeds at the base of the Chania
Falls, Thika. It is difficult to speculate as to the function
(if any) of the curious armament of the Hispince. Whether
it is formed for protection — for its structure would certainly
make it unpalatable, and probably intimidate its enemies —
or is the result of some cell stimulus as an example of over-
specialisation, is rather difficult to decide in the present state
of our knowledge.
The Cassidinae are an interesting sub- family of moderate
extent. They are usually shield- shaped or hemispherical,
OF THE FAMILY CHRYSOMELHXaE

with greatly expanded elytral margins. While alive they
surpass any other Chrysomelidce in beauty and brilliance of
colouring ; it is deplorable, however, that after death these
colours quickly fade, leaving us with a drab, dull yellowT insect.
These colours would probably be retained if the elytra could
be kept moistened with glycerine or spirits of wine ; often an
old specimen can be rejuvenated for a time by soaking in water.
Cassidince, or ‘ Tortoise Beetles,’ are well represented in
East Africa, and although the species are not as fine as those
of South America, some very gorgeous forms occur. The
genus Aspidimorpha is perhaps the most extensive in this
country, and several species are recorded by L. Ganglbauer
(‘ Insekten aus Deutsch- Ostafrika Kol.,’ p. 25) from Tangan-
yika. The Nairobi Museum possesses one or two fine species
from Uganda, and Gahan (op. cit., pp. 224 and 464) records
further interesting forms from the same country.
The larvss and pupae of the Cassidince are some of the
most wonderful of Coleopterous forms. The larvae have the
peculiar habit of covering themselves with their excrement ;
this is not free as in the Criocerince, but held firmly by a
forked appendage arising from the posterior extremity of the
abdomen. The excrement can in some species be raised and
feebly waved with a vertical motion, perhaps with the intention
of frightening its enemies. While recently collecting on the
shores of Lake Victoria, at Kisumu, I came across a small
patch of arid ground on which were growing some small shrubs
with broad, thick, light- green leaves.1 On examining these
plants I noticed a species of Aspidimorpha (?) in all stages of its
development ; the most minute larvae seen were entirely of a
bright yellow colour, with a small portion of excrement on the
dorsal surface, which, as soon as I advanced my hand, the
insect waved slowly in a vertical plane. Further advanced
larvae had, naturally, a larger piece of excrement which
assumed a definite pattern, and the bright yellow of the body
had given place to a darker brown. The pupae were also
situated on the leaves, and bore no resemblance to an insect :
they appeared as merely dry spots of excrement, dark grey
in colour, only the whole formed into a fantastic pattern.
The imagines were also present ; they appeared very restless,

and took to the wing at the least opportunity. They were
bright little oblong-ovate insects, the elytra being decorated
with red spots surrounded by black rings.
Conclusion
This concludes a very brief survey of the Coleopterous family
Chrysomelidce. Our knowledge of the group is as yet so little
advanced that any further details with reference to distribu-
tion, etc., are impossible.
Perhaps it will not be correct to conclude this paper with-
out a few words upon the subjects of mimicry and ‘ warning
coloration,’ which seem to so agitate the scientific world at
the present time. It is a well-known fact that the Coccinellidce
or ‘ Ladybirds ’ are furnished with a very conspicuous scheme
of coloration — pro exemplo, bright elytra often adorned
with striking spots and stripes. It has, I believe, been proved
that the Coccinellidce are decidedly distasteful to birds or
other animals, in the same way that Acraeine butterflies are
ignored after a primary taste. In the case of the Coccinellidce
our knowledge is perhaps a little more definite : anyone who is
accustomed to handling the beetles knows that very often
the insect exudes a yellowish fluid from between the bases of
the pronotum and elytra. Exudations of this kind have been
definitely proved to be distasteful to other animals (notably in
the large Orthoptera and ‘ ground- beetles ’ ( Carabidce )).
Certain Chrysomelince of the genera Chrysomela, Doryphora,
and others are coloured in a very conspicuous manner, such as
spots and stripes in the same way as the Coccinellidce ; in
many cases Chrysomelince marked in this way can be separated
from the Coccinellidce only by a careful examination of the
legs and antennae. Therefore it is not difficult to imagine
that marauding enemies are also mistaken, and, in consequence,
the innocent Chrysomelince are left quietly alone, free from
the horrible prospect of sudden death ! Therefore, according
to Professor Poulton and other advocates of the theory, the
Chrysomelince mimic the Coccinellidce for the sake of preserva-
tion, and adopt the ‘ warning coloration ’ of the latter family.
We do not wish to discuss the validity or otherwise of this

interesting question, but will refer our readers to the writings
of Poulton, Marshall, Beddard, and particularly to Wallace’s
chapters in * Darwinism.’
I would like to mention one adverse but interesting fact
with reference to this theory, which is recorded by W. L.
McAtee in a paper written in 1912.1 A specimen of the
Chrysomeline, Diabrotica 12- punctata, a very conspicuous
beetle, black with yellow bands, was accepted by a Blue Jay
( Cyanocitta cristata), whereas a sombre-coloured Carabid,
Scarites suhterraneus, was rejected !
In extenuation of the inadequacy of the present paper
I would mention the very small amount of material that I
have been able to examine, and the paucity of the literature to
Vhich I have had access. However, I hope that the paper
will be of some small assistance to those who, stranded in the
‘ wilds ’ of Africa, may desire to take up the study of this
fascinating group of beetles.
Those who in studjdng Coleoptera find delight and solace
are well entitled to echo the words : —

Und wert, darauf vergniigt zu sein.’

NOTES ON CEETAIN COLOUR
NOTES ON CERTAIN COLOUR PATTERNS IN
LYCMtiUDM
By Y. G. L. Van Someren
There has always been a certain amount of speculation as
to the use or otherwise of certain colours and the distribution
of them in Lepidoptera, particularly in Rhopalocera.
So-called ‘ mimicry ’ has its staunch supporters, and there
appear to be considerable grounds for the various theories
put forward. Little, however, in comparison, has been written
regarding the peculiar shape of certain species of Rhopalocera,
and this is a subject worthy of attention.
Certain lepidopterists have drawn attention to the curious
shape of the anal angle in the wings of certain Lyccenidce,
and have put forward ingenious theories as to the uses of
such peculiar formation and appendages, combined with the
brilliant spots of colour usually associated with them. I pro-
pose in these notes to record my observations on this particular
subject.
One authority has advanced the theory that the brilliantly
coloured, rounded appendages, in conjunction with the so-
called tails, are in reality ‘ false heads,’ with the attendant
eyes and antennae, and, by virtue of their shape and colour,
are a means of protecting the life of the insect against such
natural enemies as lizards.
This theory is very pretty and attractive, but assumes a fairly
high special development on the part of the insect, and a low
intelligence on the part of the lizard. To my mind a com-
promise appears to offer the more reasonable explanation.
These appendages, coloured as they are, certainly are
to the human eye objects of attraction ; and, assuming that
they appeal to the lizard in the same way, may be termed
‘ spots or areas of primary attraction.’ I refer in the first
instance to the markings on the underside.
A glance at the accompanying plate will at once show that
all these insects have been attacked, in some cases more than
once, in the same area, namely, the rear.
We can explain this in three ways — first, by applying the
[ To face p. 18.
PATTERNS IN LYCiENIDiE
19
theory of the false head, and assuming that the lizard, keen on
capturing its prey, attacked the apparently most vital spot,
namely, the false head ; or, secondly, by the compromise theory
of areas of most attractability ; or, thirdly and most likely,
by ascribing to the lizard a certain and by no means unlikely
amount of intelligence, and saying that the lizard attacked the
insect in its ‘ blind ’ area, namely, the rear.
This last explanation appears simple and the most likely,
until we come to study the actual specimens attacked.
It was my good fortune in July 1920 to find a small flowering
shrub growing against a pergola constructed of rough branches,
the former being most attractive to the ‘ Blues ’ figured, and
the latter the home of numerous wall lizards.
My attention was first drawn to this bush by noting that
the butterflies were never still for any length of time, although
feeding and sunning themselves ; this behaviour being quite
unusual, in my experience, in the species under consideration.
This strange action led me to investigate the cause,
which proved to be the repeated attacks on the part of the
lizards.
Having heard of the theories mentioned at the beginning
of these notes, I determined to try to prove or disprove them
by personal observation. I accordingly spent several hours
at the bush, and paid particular attention to the position of
the attackers and the butterflies attacked. Every attack was
made from behind, and on no occasion was a butterfly taken
from any position other than the rear.
Now, studying the plate, it will be seen that all those in
column B have the excised portion in the same area, and
symmetrical in both wings, indicating that the wings were
closed, and further, in No. 1, that the attacker was below and
behind ; while in No. 7 a double attack has been made — the
first from directly behind, and the other from above and
behind.
In some cases both eye- spots have been removed, in others
only one.
In column C the excision has not been symmetrical in both
wings, indicating that the wings were not tightly closed but
slightly opened, and further, we can see the side of attack
20
COLOUR PATTERNS IN LYCiENIDiE
well exemplified : in Nos. 1 and 2 the attack has been made
from behind and on the right ; in Nos. 8, 4, and 5, from the
left and behind, each victim having suffered from more
than one attack.
In making the sudden dart, the lizard twisted his head
to one side. It was only when the grip included part of the
body that the catch was successful.
Another contributory factor determining the position and

Position of Attacker.

2. Attacker directly behind removes a portion of both eye-spots.

shape of the excised portion is the habit which some of these
species have of rolling the hind wings — that is, moving them
up and down in a vertical position when still closed. In the
specimens taken, the excised areas are the same shape but
not in the same position on both wings.
Although on several occasions the tip of the fore wing
was the nearest point to the lizard, no attempt was made to
secure the victim. This would, then, appear to argue against
haphazard attack, and lend support to the theory of selective
position ; and so we come again to the point from which we
started.
SOME NOTES ON THE WASANYE
21
I would now mention that on a few occasions one wing
only was attacked, and this at times when the butterfly had
its wings fairly widely open, thus hiding from view the eye-spots
on the underside, but incidentally laying open to view the
very much more vivid colouring on the upper side of the anal
angle, which was less like a ‘ head with eyes,’ lending support
to the theory of attraction by virtue of colour, not shape, or
to the simple explanation that attack from behind is safer
and more often successful.
Brilliant splashes of colour on insects and other creatures
have sometimes been interpreted as being of use as danger
signals or warnings, but such cannot be the casein this instance,
as no warning is apparently heeded by the lizards — rather the
contrary.
SOME NOTES ON THE WASANYE
By Arthur M. Champion
This hunting tribe cannot be said to inhabit any particular
area, but may be met with from Kipini to Gazi, from Takaungu
to Yoi. I recently had an opportunity of visiting a settlement
of these people some thirty miles west of Mangea Hill. The
place was called Mlango Moro, but there is, I am informed,
another settlement a day’s march farther west, called
Mtanyango. The tribe call themselves * Wat,’ but are spoken
of by the Wanyika as the Alangulo. The local Elder at
Mlango Moro is called Kalime Dida, but the settlement seem
to regard one Dede who lives at Warumbe Forfa (about an
hour and a half S.E. of Shakahola) as their chief.
I found two villages, one of which had seven circular huts,
and the total population of the settlement may have been
twenty-five all told. One hut was much bigger than any of
the others, being 15 feet in diameter, and, I should judge, 10 or
12 feet in height. It was finished off at the top very neatly
in the form of a little ornamental point. Others were very
roughly put together. I measured one of what I considered
average size : it measured 9 feet in diameter and 5 feet in

support. Saplings are put into the ground in a circle, and bent
inwards till they meet in the centre, where they are tied
together. Horizontal saplings are then bound on to these
from top to bottom. On top of this grass is thrown ; only
in the case of this one big hut have I ever seen any attempt
at thatching.
The shape of the hut is that of an inverted pudding basin.
The door is 2 feet wide and 2 feet 6 inches in height. It is

closed by a grass screen. In every hut I found the grass
which the occupant used as a bed on the left, and the fire on
the right. This settlement had some shambas, and some had
built small stoves in Giryama fashion, which were placed on
posts over the fire. The doors of the huts all faced roughly
east.
The inhabitants had, unfortunately, gone on a hunting
expedition to a place called Ariba Kitengo. Their grain was
all finished, and want of food had driven them in search also
of the berries of the Mnago tree.
This is a tree of medium size,
with small rich green leaves grow-
ing at the end of each twig in a
bunch. The fruit is yellow when
ripe, and contains a white juice.
Personally I found it very un-
palatable, but I am assured that
the Alangulo like the fruit so
much that they strip a tree at
once when found.
A bow was measured and found
to be 5 feet 6 inches in length, and
the accompanying arrows 2 feet
11 inches in length. They were
poisoned, and fitted with an iron
head of a type known amongst both Alangulo and Giryama
as 4 Tali/ The head and poison, which extended five inches
up the shaft, was wrapped up in a strip of thin hide. The
feathers used were very stiff, and were probably those of a
vulture. The feathered end of the shaft was dyed red.
The Tali head is very thick and strong, and is used for
shooting big game, including elephant.
The poison is a thick black substance of the consistency
of treacle, and made from a tree called Mutsungu by the
Giryama, and Hadda by the Alangulo.
The branches are cut into pieces about a foot in length, and
are afterwards again cut up into smaller pieces, bound together,
and boiled in water for a day. Some wood of the Madiga
tree is also added. A rat called Pinji is also put into the

mixture, as it is believed that the wounded animal will not
then be able to cross a path without falling dead.
Some black substance found in the liver of a crocodile is
finally added, as it is believed that by this means the wounded
animal will at once fall dead if he should stop to drink water
by the way.
A mysterious hidden force seems to be recognised, and is
called ‘ Wak,’ the same word being used by the Galla and the
Duruma. The word is not used by the Giryama, who use
‘ Mulungu ' ; Mulunguni denoting the heavens.
The pottery found was all in the Giryama style. A honey
barrel, which was beautifully fashioned, was found to be
without mark of ownership. A small wooden drum with
bottom and cover made of skin is a universal receptacle of the
Alangulo for all kinds of food, and is carried by means of a
strip of hide passing over the forehead. These are similar
in appearance to the Kithembi of the Akamba.
The crops in the neighbourhood looked at least as flourishing
as those of the Agiryama.
The Alangulo in the neighbourhood of Mlango Moro,
where I camped, seemed very shy, and those whom I met
invariably fled into the bush. It is hoped next time, through
the medium of some friendly Giryama, to establish better
relations, and obtain some more information about these
interesting people.
EEPOET ON THE BAJUN ISLANDS
By J. T. Juxon Barton
I. People
The Bajun (Ar. Ba-gun, a white tribe), Wa-Gunya (Ki-
Swahili, Ku-Gawanya, to divide), i.e., a fractious people, a
term of reproach applied by the Southern Wa- Swahili to the
Northern and by the Northern to the Southern, or Wa-Tikuu
(Ki- Swahili, contracted from nt'i kuu, the mainland), are said
to represent the oldest form of civilisation on the coast ; their
language, the most archaic form of Swahili.
REPORT ON THE BAJUN ISLANDS
25
They inhabit the islands on the east coast of Africa lying
between Lamu and Kismayu. These islands are divided into
two groups, the northern group being known as the Dundas
Islands.
It is submitted that the inhabitants of the northern
islands are of a different origin from those of the south.
Their origin has been variously stated as Phoenician,
Himyaritic, and Hamitic. The fact that coast dwellers of all
nations can hardly claim descent from one stock seems to have
been lost sight of, and an unreasonable antiquity argued from
the ruins on the islands and on the mainland opposite to the
islands.
Sir Harry H. Johnston, K.C.B., stated that at about the
same time as the Bantu race movement, some 3000 years ago,
the Arab-Sab&ans came voyaging down the east coast of
Africa, until they ultimately settled in the S of ala district
south of the Zambesi, leaving as witnesses of their venture
the Zimbabwe and other ruins. Phoenicians also explored
the east coast, founding stations as far south as Mozambique :
one expedition, in the employ of the Egyptian King Necho,
is said to have circumnavigated Africa about 600 b.c.
Later the pre- Islamic settlements of Arabs from Southern
Arabia were revived by militant traders and missionaries of
Islam establishing themselves at Mozambique, Kilwa, Zanzibar,
Mombasa, and various ports on the Somali coast.
A colony of Mohammedan Persians (Shirazi) joined them
in the tenth century at Lamu, and Persian as well as Arab
influence began to be apparent in the architecture on the
east coast.
Until the settlement of the coast towns by the Portuguese
in the sixteenth century, these Arab states were sparsely
colonised by Himyaritic or South Arabian Arabs from the
Hadramaut, Yemen, and Aden.
A development amongst the Arabs of Muscat drove the
Portuguese from that territory, and, following up their success
at home, these Arabs attacked them on the east coast of
Africa, the Muscat Arab becoming the predominant type.
In this connection may perhaps be mentioned the traditional
arrival of two hundred and fifty Portuguese at Tula Island,
26
REPOET ON THE BAJUN ISLANDS
with an equal number of women who were, so the tradition
runs, driven out of Arabia by the Arabs. A Portuguese grave
is to be seen to this day on Tula Island.
Though immaterial, the higher type of features so noticeable
amongst the population of Faza, Patte, and Siu in the Lamu
Archipelago, is stated by the Bajuns to indicate European
blood ; and in further support of this opinion, the Bajuns of
Tula amusingly instance the Faza custom of hanging washing
to dry on a line, and taking the clothing down with a tearing
motion, instead of laying on the beach with stones as weights,
and carefully folding in the native fashion.
A rough chronology of the coast would seem to be :
b.c. 600. Pharaoh Necho of Egypt sends a Phoenician
expedition, which is said to have circumnavigated
Africa in three years.
a.d. 720. First Islamic settlement.
1497. Vasco da Gama rounds the Cape and visits the towns
on the coast.
1584. Portugal is in possession and defeats Turkey, who
attempts to wrest from her the Zanzibar coast.
1698. By this date the rising of Arab power of ’Oman
has driven Portugal out of all her possessions
north of Mozambique.
1752. The Portuguese, having finally lost Mombasa in
1780, recognised the Muscat Imamate of the
coast.
1888. The Imperial British East Africa Company receive
a charter.
1894. The I.B.E.A. Company is withdrawn, the territory
becoming a protectorate.
The maps of Africa, according to Herodotus, 450 b.c., and
Eratosthenes, 200 b.c., do not extend south below what is
now Cape Guardafui.
‘ The Periplus of the Erythrean Sea,’ circa a.d. 80, is a
navigation guide of the east coast of Africa to about the
latitude of Zanzibar.
Ptolemy, in about a.d. 140, marks the coast of Jubaland
and Italian Somaliland as simply 4 Barbaria,’ the interior as
REPOET ON THE BAJUN ISLANDS
27
‘ Azania,’ Kismayu 4 Parvum Littus,’ Port Durnford or
thereabouts 4 Magnum Littus.’ A1 Idris, in 1154, follows
Ptolemy in 4 Barbaria,’ marking islands off the coast.
Martin Behaim, in 1492, leaves the coast a blank.
Diego Ribero of Seville, in 1529, showing Lamu, Patte, the
Bajun Islands, the mouth of Juba River almost accurately,
embellishes the coast and interior with drawings of elephants.
Pigafetta, in 1591, shows what may be the Tana River,
Barkao, the mouth of the Juba, and islands.
Jacob van Meurs, in 1668, shows a town at Kismayu called
‘Liongo,’ and marks the vicinity of the Juba River ‘ Barenboa,’
calling an island, with a town on the mainland opposite, 4 Tetile ’
(Tula).
H. Moll, in 1710, calls the coast of Jubaland ‘Barra Boa,’
and the interior ‘ Quilimia.’
Smith’s New Map of Africa, 1815, shows a town on the
Juba mouth and the country between the Juba and the Tana
as ‘ Galla.’
* Liongo ’ was a semi- mythical Swahili hero, vulnerable
only in his navel to a copper needle, the subject of many poems,
who lived in the neighbourhood of Lamu and who was buried
at Ozi. Lamu and Patte are, however, shown in Jacob van
Meurs’ map, while Liongo occupies the place of Kismayu.
‘ Barenboa,’ ‘ Barra Boa ’ : the Bajuns, the Gallas, and the
Somali use the word ‘ Barobaro ’ to denote an unmarried
youth of the warrior class. Possibly also the word may be
derived from 4 barra ’ (Ki-Swahili, Arabic, 4 the interior ’).
‘ Quilimia ’ (Ki-Swahili, Kilimia, 4 the Pleiades ’).
In attempting to deduce an origin of these people, the
Himyaritic element pervades the coast ; to a lesser, much
lesser, degree the Persian ; the Portuguese, with the early
crusading zeal of Roman Catholicism, are little likely to have
mixed their blood, on pain of purgatory.
The Persian element persists in a lesser degree, in that
this tenth-century settlement of Shirasi adventurers would
seem to have definitely limited itself to Lamu, where the
prevailing type to this day is in marked distinction from the
Bajuns, and it is to be remembered that until, and after, the
arrival of the English, internecine war was rife.

BEPORT ON THE BAJUN ISLANDS
There remains, then, what may perhaps be called the
Hamitic theory. This seems to have received little con-
sideration, despite the traditions of the Bajuns, and despite
the obviously Hamitic features of many of the islanders.
In brief, the Bajun tradition is that they came from the
north-east and occupied the present Garreh country, north
of Dolo ; were driven south-east by the Galla invasion ; settled
at Afmadu ; were driven by the Galla to the coast at Kismayu,
and thence to seek refuge in the islands.
They claim to have dug the so-called wells at Afmadu, and
to have possessed camels.
A further point in estimating their origin which does not
seem to have been mentioned is that the Bantu Nyika (Ki-
Swahili, 4 desert ’) tribes (Digo, Duruma, Rabai, Ribe, Kambe,
Jibana, Chonyi, Kauma, and Giryama) occupied the Shungwaya
or Burkao (Port Durnford) country, and were driven south
by the Gallas. These people now occupy the littoral from the
Tana River to the, until recently, Anglo-German boundary.
The Bantu dialect spoken is akin to Ki-ngozi or Ki-ngovi,
the old language upon which modern Ki-Swahili is based.
The Persian and Portuguese elements seem justly negli-
gible. There then remain the Southern Arabian, the Hamite,
and the Bantu as progenitors.
(1) The Arab. — The Arab, driven by trade, pestilence, or
famine, left his country and established stations along the
coast. Were pestilence the reason, the disease would have
followed ; were famine, he would not have chosen the arid
coral rag of the islands, open to the winds, with an inhospitable
mainland, to give him sustenance. The factor was probably
trade ; and gold mines were worked near the Zambesi early in
the history of man. Moreover, harbours near to food centres
were necessary, and he chose Lamu and Mombasa as his home.
(2) The Hamite. — The Bajun claims what almost may be
called ‘ Somali ' descent. He was driven from Garreh to
Afmadu, from Afmadu to Kismayu, and from Kismayu to the
islands by the Galla, and the Galla occupied Jubaland until
fifty years ago.
He states he dug the wells at Afmadu : these wells are
almost horizontal caves, not the work of Arab craftsmen.
REPORT ON THE BAJUN ISLANDS
29
He did not build with stone at Garreh, nor at Afmadu,
nor Kismayu ; but on the islands he built with stone in the
Saracenic style — -and work in stone is not learned in ten genera-
tions, and now the Arab element has disappeared he no longer
uses stone.
The ruins on the islands have been stated to be of great
age : all the evidence would seem to be to the contrary. The
style is Saracenic, which style gave to Europe the battle-
ments and portcullis of the medieval castle, and this style has
undergone few if any modifications since its inception. The
material used was coral rag and lime, and one has not to go
far afield to see the result of but a year’s neglect on such
buildings on less exposed sites.
The people of Burkao (Port Durnford) claim kinship with
the Rendile, and state that when accompanying the late Mr.
Reddie, then District Officer, Port Durnford, on his journey
to Rendile, they found lost relatives and brothers. The
Rendile are of ‘ Somali ’ origin.
Bwana Hamudi, late Headman at Port Durnford, was of
pure Garreh descent.
(3) The Bantu — The place of origin of the Nyika tribe is
the Jubaland littoral. Odd survivors owning stock as Somalis
are still to be found, and, still more curiously, Bajuns (Tula
Island) have spontaneously stated the former neighbourhood
of the Wa-Nyika.
The Wa-Nyika were possibly agriculturists in the fertile
watered valley between the Anole and Burkao creeks, now
the Herti-Magharbul grazing. They were obviously hunters,
nomads if necessary , undoubtedly subject to slave raids,
equally undoubtedly to Mohammedan concubinage ; and
harassed from the coast by slavers, from the interior by the
Galla, they sought refuge from their oppressors in compara-
tively recent times, and crossed the river Tana, as did the
Galla in their turn when harried by the Somali. If this is,
then, the parentage of the Bajun it is submitted that their
story should run as follows :
The great migration of Hamites, increasingly obvious in
the southern movement of the Somali tribes of the present
day, began in the mother country of middle Egypt and Arabia.
80
REPOET ON THE BAJUN ISLANDS
One branch, the Gallas, reaching Abyssinia, passing, driving
before it all weaker tribes, mingling with its captives, drove
the so-called Bajun (nomads also) from well to well until a
sure refuge was found on the islands. The coast and hinterland
was occupied by the Nyika tribes, and with these the islanders
mixed : the struggle with the Gallas still continued, the
islander and the Bantu being attacked as the former tried to
regain and the latter to retain his hold upon the mainland.
And so the struggle continued until and after the coming of
the Arab from the south. The Arab came as a trader in
ivory and slaves, and by barter with the Galla and the help
of the Bajun, secured both the ivory and the slaves.
Mixing with the Bajun and Bantu, he built houses and
mosques 1 where no real prosperity promised (for the supply of
ivory and humanity could not last, since both beast and man
run from fear), and where but the scantiest crops could be
grown, so that he brought grain from Lamu and the south in
dhows. He was at his greatest prosperity in the eighteenth
and early nineteenth century, when even the Galla, pressed by
famine, sold his children, and so until the middle nineteenth
century, when the Galla hunter disappeared into the dense
Tana bush before the Somali coming by sea and land.
With the advent of government, the abolition of slavery and
the preservation of ivory, the Arab returns south, leaving his
houses, his mosques, and a people of mixed Hamitic, Bantu,
and Arab blood using his buildings until the action of the
winds and sea crumbled them away, and returning to their
previous state of bare sustenance.
The Bajuns are light coloured, intelligent, and unwar-
like. They are Mohammedans of a devout type, in marked
contrast with the Pharisaical Somali. They are miserably
poor, extremely thrifty, but spend lavishly when in funds.
The average monthly earnings of the Bajun may perhaps
reach seven rupees.
They have some knowledge of agriculture, and, what is

81
more important, the will to work : they obtain small crops
from the most impossible soil.
They are courteous and obliging to strangers, and
exceedingly friendly to government.
They possess a certain amount of low cunning, which is
naturally more obvious in the markedly Hamitic type, but are
otherwise honest in their dealings. They borrow extensively
from Indian (Kismayu) traders, loans sometimes reaching
Rs. 4000, which is evidence of their integrity or of an ivory
trade, for they can give no security.
Their houses are built of wattle and daub, the palm for
the roof coming from Lamu. Shelves and crude ornamental
devices are sometimes contrived in the walls of the rooms.
The houses are well-built. Bajuns are unable to build in
stone, and probably they never knew the craft. The wells are
all of some age.
The upanga is carried by the man, and is often ornamented
with silver ; this sword is a cutlass, and different from the Arab
weapon.
Their dances are the usual advancing lines of men and
girls ; married women should not dance.
Two dances are performed exclusively by men, the one a
sword-dance, the dancers prancing around one another, cutting
at head and foot, a cloth being held in the free hand as a shield
with sometimes another cloth in the teeth ; the other is the
old English quarter- staff, save that damage is rarely done.
To this, drums and brass trays are beaten. The former is the
Hazua, the latte^ the Kirimbizi.
Women and girls have also dances, no man being present.
This is the Msondo, or school of love, presided over by a Somo,
an adept in the art of attraction, the pupil being called Mwari.
The original purpose of the Msondo was undoubtedly to
prepare girls for the housewife’s duties, the present practice
is best imagined. A polite custom of the islands dissuades a
man returning at night from landing and entering his house.
The women possess long hair which they wear in a coif,
the ears are pierced for Arab ear-rings, the lobes often distended
for the introduction of coloured paper rolls ; the use of
ornaments is lavish. Both sexes chew snuff mixed with
82
REPORT ON THE BAJUN ISLANDS
magadi (soda). Comely women are confined to their houses ;
this is by no means general, and the shapeless blue buibui is
not worn.
The threefold divorce is rarely used, the first formula being
regarded as sufficient.
Fish is the staple diet : there are, however, clans who eat
no fish. Most shell-fish, other than oysters, are prized ; both
men and women string cowries for the Indian market. Corn
is sold at 12 lb. (two pishis) for the rupee. Seaweed is eaten.
Buni (unhusked coffee) is as necessary a drug to the Bajun
as to the Somali and Galla.
A few goats and cattle are to be found on the islands.
Fishing dhows are made of Msindi wood, which has the
disadvantage of not rising to the surface after immersion, the
planks being bound with fibre rope and rendered seaworthy
with shark fat. Very few large dhows are to be seen, and these
represent bad debts of Indian merchants in Kismayu. The
coastal carrying trade will be in time entirely in Indian hands.
Small white pennons are flown on the bowsprit to propitiate
the elements. A person on his first voyage must tie some
article of clothing to the mast until the journey’s end, and
redeem it at a price.
The boating songs are exceedingly tuneful, and would be
worth collection.
The method of catching the turtle by the Koyama people
is worth recording. The taza, a slender sucking fish, about
two feet or so in length, is caught. When a shoal of turtles
(kasa) is seen, this fish is thrown into the water attached to
a line. The taza almost 4 hunts ’ his enormous victim, fastens
himself to the under portion of the throat, sucking its blood,
and the turtle is drawn towards the boat, from which the
fisherman dives to fasten an iron ring, with a rope attached,
to the turtle’s flapper. This mode of fishing would seem to be
unique.
The Bajun is a dying race : with some help and fosterage
from Government they might be saved : their economic value
is undoubtedly greater than that of the Somali, and their
loyalty is not in question.

II. The Islands
(1) Koyama Island. — This island is situated some 21 J miles
down the coast from Kismayu, its greatest length being 3J
miles, its breadth 2 miles.
There are two villages on the island, the village on the
shore being known as Koyama, the village on the hill a mile
or so away, Koyamani. The inhabitants of this island are
markedly Hamitic in features. They regard themselves as a
distinct tribe, and seem the most feeble and dispirited of the
islanders.
The island possesses about four mosques in varying states
of repair ; a venerable ruin gives the date a.h. 1224= a.d. 1808.
Tombs of a more intricate design than those of other islands
are to be seen on the foreshore. China plates are cemented
into the mosque walls around the Kibla.
A cloth slightly different from that of Benadir is still
made.
Coco-nuts, tobacco, and some grain is grown. The people
possess a few sheep and goats. The turtle is esteemed as a
delicacy and caught in a manner already described. The wells
are extremely brackish.
Some fifty years ago, when Jubaland was in the possession
of the Gallas (an old man states), two boats’ crews, fifteen souls
in all, from one of Her Majesty’s ships arrived, the vessel
having foundered. These survivors were fed by the inhabitants,
giving written bills in exchange for meat and grain : they
camped on the highest point and remained two months when
a ship was sighted which rescued them. Their debts were
paid in full, and the late Headman possessed a letter of
commendation from a shipwrecked officer.
On one occasion Somali traders from the Benadir had put
into Tula Island and captured four children : all the slavers
were killed, and the Bajuns returned by the English.
Bajun tradition states that the islands were populated by
a race crossing from the mainland at Koyama, each section
cutting its mark on a baobab tree opposite the island. These
marks are very like the cattle and other brands of known
Hamit es.
84
REPORT ON THE BAJUN ISLANDS
The life of the baobab may exceed a thousand years : the
tree in question is of great age.
(2) Ngumi Island. — -This island is close to Koyama, its
greatest length being 4| miles and breadth 1 mile. It is
uninhabited save by two or three fishermen. Water is obtained
from Koyama. The island possesses considerable ruins of a
walled-in village. It is of no interest save with reference to
the legend associated with the mosque.
The inhabitants traded in ivory and slaves with a white
race : the tusks were packed in the long matting-bags
used for grain. On one occasion a cargo was taken, but
the bags contained but one tusk each and were packed
with camel and other bones. The traders sailed, and
on their return bombarded the village, destroying all the
inhabitants.
One woman ran for sanctuary to the mosque, praying
that she might be saved from the raiders ; her answer was her
transformation into stone. The stone has now disappeared,
but is stated to have stood near the Kibla : it has been reported
as still existent, but its whereabouts kept secret. From
this legend Astarte worship has been argued, somewhat
unwarrantably.
Men desirous of children burn incense before the ruined
shrine.
The Bajuns are unwilling to clean the old stone wells in
that each well demands a life.
(8) Chovai Island. — Chovai is the correct Ki-Tikuu name
for this island, which is called Towala by the Arabs. The
island is the most populous of the Dundas group.
It possesses very few stone ruins. The existing mosques
have been repaired recently.
Some attempt at agriculture is made on the mainland.
Sheep and goats are grazed. The water is moderate.
The inhabitants seem the most wealthy of the islanders,
are markedly Hamitic, and are divided amongst themselves.
Chovai creek on the mainland is a harbour for native
craft ; the creek, penetrating some miles inland, is fringed with
mangroves.
Ivory is probably smuggled.
REPOET ON THE BAJUN ISLANDS
35
(4) Tula Island. — -This island is second in point of popu-
lation : it is 57 miles from Kismayu, is I J miles in breadth,
3J miles in length. The water is the sweetest on the islands.
There are two villages on this island, the one Tula, the
other a mile or so distant, M’doa.
Coco-nuts grow extremely well, and with some encourage-
ment would become profitable.
The island possesses a large tomb, said to be Portuguese,
made with a cement the secret of which has been lost. The
decorations are not Islamic.
Legend has it that five hundred Portuguese men and
women landed on the island, having been driven out of Arabia :
more probably they were expelled from Mombasa or Lamu
by the Arabs in the eighteenth century.
A house, the interior decorations of which are singularly
delicate, is shown as of great age. It was built with slave
labour by the great-aunt of a living inhabitant. This woman
was of the Defarad clan of the Tunni tribe and the Barawa
people of the Benadir coast. The Tunni and Rehawen fought
with the Somalis at Giumbo and were driven north.
The three stone mosques are in good repair : the interiors
are decorated with plates : in many cases the design of this
china is modern.
On the mainland a few hundred yards from the shore, at
Kituni, is the ruin of a considerable mosque, the interior of
which is decorated with the 114 Suras of the Koran carved
in the plaster.
On the right-hand bank, at the mouth of the Anole Creek,
are more ruins, likewise on the left-hand side at Kudai.
It is submitted that these mainland settlements were in
their conception custom-houses, and, as relations with the
Galla or Wa-Nyika were established, became villages. The
custom is well known ; the grain was placed some distance
away, the tusk was brought : if either the price or the article
did not suffice, the dissatisfied warned away the other by hostile
demonstration. Manifestly the islander could not barter in
safety on his island.
(5) Kudai Village. — This is a small settlement on the
mouth of the Anole Creek, inhabited by a few Bajuns, who eke
36 . REPORT ON THE BAJUN ISLANDS
out a wretched living by fishing and attempts to grow crops.
It is marked ‘ Kituni ’ on the latest maps.
(6) Anole Village. — This is a small village of natives of
various Bantu tribes who have moved from place to place
until they have reached the head of Anole Creek, some
twenty-five to thirty miles from the sea.
Their condition is miserable, and they are in constant
dread of raids by Rer Abdulla youths aspiring to the white
feather.
The soil round this village is suitable for shambas on an
extensive scale ; corn, sim-sim, manico ( muhogo ), and tobacco
are grown.
The neighbourhood is the Jilal grazing of the Herti and
Magharbul Somalis, with whom their relations are friendly.
The water, from shallow wells, is abundant, clear, and sweet.
This stretch of fertile country extends for a considerable
distance, as far as Busbushli on the Burkao Creek.
A road is said to have been cut by Mr. Haywood, District
Commissioner, from the head of Anole Creek to Kudai. It is
not visible, and the camel track followed through thick bush
is a nine to ten hours’ march. (European.)
(7) Tosha Village. — This is a small and insignificant
village some two miles from Kudai on the mainland. The
water is moderately good.
(8) Sheh Village. — -This village, some five miles south of
Tosha on the mainland, has been abandoned. No water is to
be found, and mosquitoes with sand-flies in the mangroves
render camping impossible.
(9) Port Durnford Village. — This is marked as Burkao on
maps ; it is called ‘ Birikavo ’ by the Bajuns.
Formerly a Government station was maintained, and a
considerable village was built, trade being with the Abdulla
and Magharbul Somalis. It has since been abandoned.
There are ruins of an old village at Port Durnford and of
a pier.
The water is impossible even for native consumption, and
for Europeans the rain-tanks must be supplemented with
water brought in dhows from Busbushli, some twenty miles
up the creek.
REPORT ON THE BAJUN ISLANDS
37
The harbour is suitable for large vessels ; boats drawing
four to five feet can enter the creek some nineteen miles, which
is navigable a further sixteen miles, as far as Wayore, by craft
drawing nine inches or so.
Busbushli, where a large supply of fresh water is to be
found, is the grazing of the Rer Abdulla section of the Ogaden
Somalis during the month of January.
The Mohamed Zubeir Ogadens claim a vague suzerainty
over this section.
Busbushli would seem a natural basis for operations
against the Rer Abdulla.
The Administration house at Port Durnford is a large and
commodious building, erected by the late Mr. Reddie, when
District Officer.
It is now sadly in need of repair in every particular. The
roof beams have fallen in some places, the windows and doors
are broken, the floor has cracked, the verandah is a mass of
rubble. The house has been in the occupation of a Police
Post.
The inhabitants of Port Durnford wish to move to Ras
Mnarani, some six hours distant down the coast, owing to the
suitability of that place for shambas, water and grazing, and
the impossibility of the water at Port Durnford.
(10) Ras Mnarani — This can scarcely be called a village
as yet. The inhabitants of Port Durnford, however, are
desirous of moving thither, where water, grazing and some
cultivation is possible.
Ras Mnarani is six hours’ march from Port Durnford.
III. The Coast
The coast-line of Jubaland from the river Juba to Ras
Kiambone is about 120 miles long, a practically continuous
line of sand-hills.
There are three tidal creeks — -Chovai, Anole, and Burkao.
The creeks are fringed with mangroves, mwea, mkandaa
and mutu trees, all of some commercial value : —
(1) Chovai Creek. — This creek lies opposite to Chovai
Island, and is suitable for coasting craft.
38
REPORT ON THE BAJUN ISLANDS
(2) Anole Creek. — This creek is suitable for boats drawing
three to four feet for about five miles. Canoes and small
fishing-boats can be punted or sailed for this distance, and
can proceed a further twenty to twenty-five miles in the dry
season.
The journey to Anole village at the head of the creek
should not be attempted by Europeans by land or water in
one day.
(3) Burkao Creek. — Port Durnford, a sub- port, is a sheltered
anchorage of about six fathoms. A steamboat has ascended
the creek for about twenty miles in the dry season to Bus-
bushli. Dhows drawing four to five feet can reach Busbushli
at any time, and canoes, Wayore, a further sixteen miles.
The rumours of tsetse-fly would seem to be an obstructive
Somali (Herti) myth.
This tribe grazes its cattle along the coast-line to Port
Durnford, and what is more, along the Chovai and Anole
creeks, the rank vegetation of which should harbour all manner
of insects.
IV. Communications
(1) By Sea. — Journeys by sea are naturally subject to
the N.E. and S.E. monsoons. The former blows roughly
from April to August, the latter from September to March.
During both monsoons the current is stronger near the land ;
despite this, the more speedy mode of travel against the
monsoon would seem to be poling along the shore. The time
taken between island and island is a matter of circumstance.
(2) By Land. — The owners of boats on each island take it
in turn to keep a ten days’ watch. A fire is lit on the mainland,
and travellers are ferried across to the island, where water can
be obtained.
Chovai Creek has no ferry.
Y. Trade, Products, etc.
The Bajuns would seem to do a great deal of the coastal
carrying trade. In reality this business is rapidly becoming
a purely Indian concern.
NOTES ON EAST AFRICAN MAMMALIA
Fishing is engaged in mainly as a means of livelihood.
Cowries and dried sharks’ flesh are bought by Kismayu
traders.
Pearling might become profitable, but the Bajuns do not
possess the power of deep diving.
Coarse ‘ carriage ’ sponges are to be found.
Ambergris and turtle shell are rarities.
The question of grain for food deserves special consideration.
The Juba river strip is in the hands of Arabs financed by
Indians : the Bajuns on the islands consequently starve.
I he coral rag of the islands is not fit for agriculture : an
attempt is made to grow crops on the mainland a few yards
from the shore : this is but little better.
The only arable land adjoining would seem to he the almost
well- watered valley or 4 tug ’ stretching from Mtoni at the
head of Anole Creek to Busbushli, twenty miles up the Birikou
Creek. The Chore or Joreh country is also watered.
Coco-nuts grow well on Tula Island, and would do well
at Kudai and Port Durnford.
Trees of commercial value are to be found at Chovai, Anole,
and Birikou creeks. These are 4 borities ’ ; 4 mweah/ small
borities used in the construction of native huts ; 4 mkandieh/
a wood used for burning lime ; 4 mutu,’ a tree used for making
native beds, chairs, etc., and burning lime.
Wild rubber is to be found in the vicinity of Port Durnford.

By Arthur Loveridge
One day I tossed the still warm body of a newly-killed rat
to her to see what she would do. First seizing the tail in her
mouth she defied anyone to take it from her, then she subjected
it to a critical examination, opening the mouth and looking in-
side, licked the blood from its nose, examined its fur minutely
40
NOTES ON EAST AFRICAN MAMMALIA
and appeared to capture and eat some fleas which she found
there. After this she climbed to her box upon which she sat,
and placing the rat between her knees nursed it in a most
comical way. She clung to this rat for two days, defeating
every effort to deprive her of it ; by the end of this time all
the fur was off, the carcase was positively green and liquid,
and as she held it in her mouth the flies buzzed all about her.
On the third day she gnawed through the telephone wire
with which she was attached to her pole, and escaped. I
recaught her the same afternoon and fixed her with a light
chain ; after several attempts on this, she settled down and
became very docile and affectionate. Alas ! Two months
later she died. One morning there were signs that she had
had a bad attack of diarrhoea during the night ; in the morn-
ing she was lying on her side toying with bits of gravel. I
immediately let her loose and she took a little milk and sugar,
she then went to the wash-basin in which she stood her fore
paws and drank deeply. I lifted her on to the bed and she
bit me. I made her comfortable but she arose and went
to the other monkey, throwing herself down beside him in a
very exhausted manner. C. rufilatus showed its sympathy
by trying to clean Jenny’s fur.
At 7 a.m. she went towards the bush where my boy found
her about 9 a.m. and brought her back, whereupon she bit
him. One would have supposed by her appearance that she
was too sick to walk, but at 2 p.m. she went off again and hoping
she might find something in the way of medicine for her-
self I said she was to be left alone. At 4 p.m. she walked
into camp very slowly and on reaching the first hut she fell
down in the shade in the most abandoned manner. Salimu
brought her up and laid her on the bed looking most humanly
forlorn. Almost immediately, however, she sprang up, clam-
bered up a strand of wire with agility, hurried across the top
of the python’s cage, descended the wire netting on the further
side and ascended to her own box. All this was done with
such agility that I remarked to the boy that I feared she was
not so ill as she looked, but native-like was making the most
of it.
How grossly I had misjudged her was revealed next

morning, when her dead body was found in the mouth of
a drain or waterway which led from the python’s cage.
Whether she had gone there seeking water, or had crept in
with the idea of hiding away, it would be impossible to say.
Colobus abyssinicus caudatus, Thos. — A troop of the beau-
tiful White- tailed Guerezas were seen in the West Kenia
Forest, where they went springing and swinging through the
tree tops ; their arched tails with long hanging fur looked
very fine. Professor Gregory, in his work ‘ The Great Rift
Valley,’ says that far from making them conspicuous, as one
might suppose, the long hanging fur has the effect of making
them appear like one of the great tufts of lichen ( TJsnea )
with which the trees are draped. The only specimen the
writer has seen in captivity was captured in a village near
Kabete. When I saw it six weeks later the children who
had made a pet of it had made it so tame that it would feed
from the hand. This animal was very old ; young ones have
a little thumb which disappears with advancing years.
Papio ibeanus, Thos. — No baboons were ever collected. In
the Forest Reserve at Nairobi they were very plentiful. They
were very noisy animals, uttering a deep bass semi- bark
which has, I believe, been likened to ‘ chaoma.’ If one
remains quiet in the forest, they come within about fifty
yards and look down from amongst the foliage ; as soon as
one stirs, away they go crashing from tree to tree, setting
all the branches swaying. One morning my attention was
drawn to a party of them on the Limoru road, near 3rd
Avenue. Though it was only 8.30 a.m., there was a fair
amount of traffic passing along the road. These baboons
had come from the forest and were rooting about among
the hut3 of a temporary P.W.D. road-makers’ camp. The
natives were all away at work, the grass huts were deserted,
so the baboons had it all to themselves. One old fellow
seemed very busy stuffing handfuls of something into his
mouth. Keeping a galvanised- iron shed between us, I walked
quietly across to him so that he did not see me until I was
within twenty feet. He then looked up, gave a bark, and
cantered away like a great dog. He only retired a short
way, then swung himself up into a very small tree, where
42
NOTES ON EAST AFRICAN MAMMALIA
he joined two others that had escaped my notice. The rest
of the troop acted in a similar way instead of making off
into the forest.
When making camp one stormy evening in the Kedong
Valley we heard the familiar bark, and looking up saw one
great brute silhouetted against the sky ; he was sitting on a
large boulder on the very brink of a two- hundred-foot precipice.
At Longido West we were called upon to stand to arms
at 2 a.m. one morning (24/11/16), as shots had been heard
up the mountain. In the morning it transpired that a troop
of baboons, stealing down to the water to drink, had been
mistaken for German askaris by the Indian picket ; the latter
had fired upon the animals, killing two.
Trekking between Arusha and Moshi, in dry, rock- strewn
kopje country, several parties of baboons were seen over-
turning stones in search of insects which they like. At
Kongwa, parties of them raided the mealies in broad day-
light. Sentries posted in prominent places kept a good
look-out and gave warning of the approach of anyone with a
gun. It was intensely amusing (except to the owner of the
mealies, I suppose) to watch them making off when thus
disturbed. Big and little ones, with an armful of mealies
and a mealie or two in their mouths, would lope away on
three limbs, and in a few instances on two limbs, having the
arms occupied with the mealies.
At Dodoma they lived on the kopjes ; on the lower slopes
of the Uluguru they might be found any evening, generally
rooting about in the natives’ shamhas or among the open
bush in the ravines. The largest party ever seen was crossing
a plain at West Kenia ; there must have been nearly two
hundred of them, and many of the mothers were carrying
young ones on their backs.
Small Grey Lemur. — When at Msiha River (Shell Camp),
I heard that one of the men in the Calcutta Volunteers had
a tame lemur. I called to see it. The little creature was not
more than eighteen inches from tip of nose to end of tail.
This prisoner of war was chained to a sapling with a little
belt around its woolly w?aist. It had the distinction of living
on army rations, and one of its principal stunts was to get

43
inside empty two- lb. jam tins, which one would have thought
impossible. Once inside it would revolve slowly round and
round until the tin was as bright as the day it left the factory.
It would then bolt for its tree, and mounting to the topmost
branches sit down at leisure to lick the jam off its fur.
Galago hindei, Elliot. — The lemurs, known to the SwTahili
as komba, are to be heard crying in the trees at Frere Town,
Mombasa, almost nightly. Probably they live royally upon
the prolific mango crop. They are captured at times by the
natives in the following manner. Pombe (native beer) is
placed in the trees in the half of a coconut- shell ; the lemurs
are fond of this and drink until intoxicated. If the tree is
visited early the following morning, the creature is found in
a fuddled condition and falls an easy prey, for its judgment
in making the prodigious leaps by which it would normally
escape fails under these circumstances, and, the creature, if
it attempts to jump at all, falls to the ground. A single
specimen was obtained some seven miles from Frere Town,
where it was found sleeping in thick bush about fifteen feet
from the ground.
Galago panganiensis, Matsch. — For notes on this species,
both in the wild state and captivity, see Journal, No. 16.
Pteropodimj
Epomophorus crypturus, Peters. — This Fruit Bat was met
with at Lumbo, Mozambique, where five specimens were shot
one afternoon, hanging singly, not in colonies, in mango
trees. They wrere all females, each containing a single foetus.
Another shot at the end of September (80/9/18) had a much
more developed one. The largest of these bats was 5§ inches
in length, with a wing-spread of 2 feet less half an inch.
Female, 148, 0, 20, 25, 596.
Epomophorus minor, Dobs. — This species was plentiful at
Tabora, Morogoro, and Dar-es-Salaam. At the former place
they were found in a mango plantation ; at Morogoro hanging
in the palms which border the roads, and also in the acacia
trees ; at Dar-es-Salaam hundreds of them occupied an old
Arab building which was in ruins. It was a wonderful sight
44
NOTES ON EAST AFEICAN MAMMALIA
to see these bats hanging by their feet along the mid-ribs of
the coconut-palm fronds at Morogoro. In January thirty-
eight were counted on a single frond, twelve on another, and
many of the other trees were loaded in a similar way. Two
years later with two shots I procured twenty-one specimens.
In July these creatures seem to go elsewhere, and not one
was to be seen ; they had not been molested at all prior to
this.
These bats have little white shoulder-tufts when mature ;
by a curious in-turning of the skin they can conceal them from
view. The largest specimens taken were from Morogoro,
where two females had a body-length of 5J inches and a
wing-spread of 28 inches. Female, 140, 0, 16, 19, 584.
Epomojphorus wahlbergi, Sund. — Common at Nairobi and
Dar-es-Salaam. At the latter place great numbers of them
assembled in the mango trees, and their cries could be heard
in the palace grounds all night long. It was by far the largest
of the three species obtained, and also the handsomest, the
fur being less brown and more mustard-coloured : there was
considerable individual variation, however. The largest speci-
men was a male from Dar-es-Salaam, measuring 6f inches in
body and 24| inches in wing-spread. Male, 160, 0, 22, 25,
290-680. Like E. minor, many specimens were infected with
a small red acarine (?) parasite on the borders of the wing
membranes.
Emballonuridjg
Taphozous mauritianus, Geoff. — Found on the trunks of
mango trees at Morogoro and on the coconut palms at
Dar-es-Salaam. The first specimen was seen on 18/1/17,
whilst walking up the long road to Government House,
Morogoro. In the native town this road is bordered with
shady and generally very dusty mango trees, upon the bark
of one of which I noticed something white. Upon closer
inspection this proved to be a bat performing its toilet. The
colouring of the back fur was fox-grey. The underparts were
pure white, and the membranes of the wings so transparent
that it had the appearance of a small tern when on the wing
GOLLBOTED OR KEPT IN CAPTIVITY
45
in daylight — this illusion was no doubt largely due to the
manner of its flight.
A closer examination of the other trees proved the bat
to be quite common ; a pair would be generally found together
clinging upside down to the trunk. As soon as they realise
that they have been observed they scramble round the bole
of the tree with the agility of a gecko— they almost appear
to glide. It is due to their alertness in this respect that I
have not discovered them before, though frequently passing
along the same road. The only occasion on which they were
found in a different situation was when a single pair were
seen under the eaves on a rough-cast wall ; in this instance
they travelled along the wall and round the corner of the
house with the same quick movements as they display on
the tree trunks. The largest specimen was a female from
Morogoro, 3J inches in length, head and body only, and a
wing measurement of 16f inches. Female, 90, 23, 32, 22, 422.
Nycterid^j
Nycteris cethiojpica luteola, Thos. — A specimen of this bat
was smoked out of a drain running beneath a pathway at
Frere Town.
Nycteris revoili, Robin. — Met with at Morogoro and
Mpapua. In the former locality three specimens were
captured in an ant-bear hole after digging down for five feet
and along for perhaps six. This hole was out on the plain,
and the find was interesting as it showed where these creatures
put up during the day. The Mpapua specimen was found in
a dark room in a house where there were some hundreds of
bats.
There were patches of a red acarine (?) parasite behind
the ears of one of the Morogoro specimens and on the wing
of a female close to the body. In this specimen there were
two holes in the wing-membrane, close to the parasites,
which may have been caused by the host endeavouring with
its claws to allay irritation. The largest specimen was a
male measuring 2f inches in length and 14| inches across
the wings. Male, 70, 56, 12, 32, 175-376.
46
NOTES ON EAST AFRICAN MAMMALIA
Megadermidje
Lavia frons, Geoff. — At Morogoro and Dar-es-Salaam. In
the former locality they were found hanging in pairs, rarely
more, in bushes or thickets on the plain. When first seen
they appeared to be bright foxy-red in colour, but this impres-
sion is false, for it is only the huge ears and wings that are
of this hue ; the body is clothed with long, soft, blue-grey fur.
They are expert in flitting about in dense thickets, and will
not let one approach within ten feet of them. Towards
evening they appear to leave the thicket and hang from some
spray, exposing themselves to the last rays of the setting sun.
At Dar-es-Salaam they hang in the bushes along the sea shore.
A male shot at Morogoro on 19/5/17 had five globular
growths between skin and flesh on the breast and neck.
These were about an eighth of an inch in diameter and came
away readily, appearing to be a very thin-skinned sac con-
taining aqueous matter. The largest specimen taken was a
female, 2§ inches long and 17| inches across the outspread
wings. Female, 68, 0, 10, 45, 190-450.
RHINOLOPHID2E
Bhinolophus hildebrandti , Pet. — Taken at Mpapua and
Kongwa in buildings. The pair from the latter locality were
the larger, the female measured 2| inches in length and
16f inches across the wings. Female, 4, 42, 18, 29, 190-426.
Hipposiderid^j
Hipposiderus caffer, Sundev. — A female was taken at
Morogoro, 8/1/18. Length 2| inches, across wings 11 J inches.
Female, 54, 32, 7, 18, 131-292.
Hipposiderus ruber, Noack. — A couple of specimens of
this bat were found bottled in a German house at Morogoro.
Yespertilionid^j
Pipistrellus nanus, Pet. — Some of these small black
bats were brought me by a native collector. I think they
were found in banana palms. The bodies were no larger
COLLECTED OR KEPT IN CAPTIVITY
47
than that of a Death’s Head Hawk Moth. The largest
specimen was a female 1| inches long and 9| inches across
the wings. Female, 41, 41, 5, 11, 108-238.
Scotophilus nigrita dingani, A. Sm. — Only one specimen of
this yellowish bat was taken at Dar-es-Salaam, 11/18.
Scotophilus viridis , Peters. — A single specimen was taken
at Morogoro on 15/9/17.
Eptesicus rendalli, Thos. — This species was occasionally
seen flitting about in the gloaming at Lumbo. It was, how-
ever, far from common, and the only specimen obtained was
brought me on 27/9/18. This was a male 2 inches in length,
52, 32, 6, 10, 24.
Glauconycteris argentata, Dobs. — This West African bat is
considered somewhat rare, and was only met with at Morogoro,
where it was certainly very local. They appeared to be
confined to three roads — namely, Palm Street, Horne Street,
and Station Road. The first time they were seen (16/1/17)
I climbed upon a barrel and obtained five with one sweep of
a butterfly net. A few months later (6/4/18) I made a close
examination of the palm trees in the neighbourhood. On
two trees were single female bats, and on a third were sixteen
bats on a single palm frond : they cling to the ‘ leaves ’ near
the mid-rib in groups, only two to four on each leaf ; they do
not hang clear with heads down, but cling to the leaf with
their tails towards the mid-rib ; the head of the one nearest
the mid-rib rests upon the back of the next bat in front of
him. Generally they were assembled upon the lowest branches
at a height of 20-25 feet from the ground. By stopping a
cart loaded with sacks of mealie and climbing upon it, I was
able to come within reach of a group of eighteen, of which I
secured ten. The biggest number ever seen on one frond
was thirty-two (21/11/18).
The largest specimen was a female, 2J inches in length
and 12f inches across the wings. Female, 58, 0, 29, 17, 144-324.
Molossidje
Cheer ephon emini, De Wint. — A single specimen of this
bat was collected at Dar-es-Salaam on 7/11/19. There were
48
NOTES ON EAST AFRICAN MAMMALIA
large numbers of these bats in the roof of the Kaiserhof Hotel
and adjoining buildings. Length, 2§ inches; across wings,
12J inches. Male, 65, 46, 12, 17, 150-818.
Cheer ephon limbatus, Peters. — This specimen was very
abundant in the neighbourhood of Mombasa, being a perfect
pest in some of the houses at Frere Town, where they lived
beneath the roof. Considerable variation in colouring was to
be seen in the large series of skins collected. The parti-
coloured brown and white of breast is most common, but in
many specimens the white was almost absent, the darker
colour of the flanks impinging upon it. In the young the
darker colour was more of a blue-black than brown. In the
adults brown of the back fur is liberally sprinkled with white
hairs. The largest specimen was a female 2J inches long
and 11 J inches across the wings. Female, 58, 84, 5, 16, 188.
Soricidje
Crocidura fumosa johnstoni, Dollm. — This small shrew was
occasionally found when clearing away sisal fences at
Morogoro. This sisal harbours much dirt and many small
creatures. On one occasion a shrew, only 3 inches in length,
was put into a tin with a mouse ( Leggada bella , subsp.) and a
gecko (Hemidactylus brooki). On opening the tin a very
little while after it was found that the shrew had killed and
eaten the mouse except for the feet and a few fragments of
fur and skin; the tail of the gecko had also been devoured.
Male, 90, 57, 14, 10.
Crocidura hirta, Peters. — A single specimen was found
bottled in a German house at Morogoro ; after spending four
months at Lumbo a specimen was found dead upon the
railway line only a day or two before departure, so it can
hardly be reckoned as common there. Female, 92, 51, 12, 6.
Macroscelid^j
Bhynchocyon petersi, Boc. — At Makindu (Shell Camp),
20/7/16, I was brought a large and handsome Elephant Shrew,
shot in the bush near by. Female, 270, 213, 83, 32.
COLLECTED OR KEPT IN CAPTIVITY
49
Elejphantulus ocularis, sp. nov. Kersh. — This new species of
Elephant Shrew was common at Dodoma, though very-
difficult to obtain owing to its custom of bolting into the
densest thorn-thickets when approached. One of the largest
females measured 142, 120, 33, 24.
Petrodromus nigriseta, Neum. — Not very common in open
bush near Morogoro. A specimen was shot one morning
(12/6/17) on a path which was being crossed by a safari of
siafu. The stomach of the shrew was full of the ants. It
seemed a most extraordinary thing that so timid a creature
could capture and eat siafu. Largest specimen taken was a
female, 225, 170, 50, 36.
Petrodromus rovumce, Thos. — These shrews were heard on
several occasions, but not seen for two months after arrival
at Lumbo. Local natives were then consulted, and we learnt
that the creatures might be captured with comparative ease.
Bag- nets are made with fine sisal thread ; the closing thread
around the neck is attached to a twig fixed in the ground
alongside the path where the bag is set open. A drive is
then made by natives pushing their way through the under-
growth ; this is sufficient to scare the shrews along their runs.
The action of the shrews bolting into the bag closes the neck
of the bag so that the animal is netted uninjured and is picked
up immediately by the following native, who, liberating it
from the bag, transfers it to a sack. On arrival in camp
they were chloroformed.
On examining their stomachs only ants -were found ; but
at 7 p.m. one evening I saw a young one which had been
liberated in my boma pounce upon a large burrowing cricket,
with which it ran under the bed. Its actions were as rapid
as those of a cat under similar circumstances. Feeding them
in captivity was not a difficult matter, as the place swarmed
with ants : a piece of bad meat was put in the shrew’s cage ;
in a very short while a steady stream of ants was going to
and from this bait ; these were licked up by the shrew as
required. Both old and young drank diluted Ideal milk,
though one could see that they were unaccustomed to drinking
by the awkward biting way they went about it. Whilst
drinking the nose was held up at an obtuse angle. How the
E
50
NOTES ON EAST AFRICAN MAMMALIA
animals subsist, here without water is hard to say ; for a month
past there had been no rain, the days glaringly hot and the
nights close without a trace of dew except on two nights.
Only one young one is produced at birth, and this takes
place during the month of October. Two young males, born
on the seventeenth of the month, measured 3 inches in head
and body and 3J inches respectively ; a foetal female on the
same date measured 2-§ inches. A live young one brought to
me on the twenty-first was 3| inches, whilst another found
on the twenty- second was much the same — both of these
were running about actively and difficult to catch. The
largest male and female measured were : male, 190, 170, 48,
82 ; female, 195, 172, 48, 35. The average of twenty- two
specimens of both sexes was 180, 157, 49, 31.
The ears of every adult specimen were in a very bad
state owing to numbers of small grey ticks on the posterior
border. Some ears were ragged, presumably made so by the
scratchings of the animal in its attempts to rid itself of the
irritating parasites. Here the ticks confined themselves to
the ears, but at Morogoro the ticks on P. niqriseta were found
all over the body, being particularly plentiful on the under-
side of the tail. Round worms were found sparingly in the
stomachs of several.
Felid.®
Felis leo massaica, Neum. — A lion passed through the
outskirts of Nairobi on the night of 24/4/15 — its spoor on
the flower-beds in the Commissioner’s garden was shown me ;
at dawn it was seen near the Arboretum. Lions were very
abundant on the slopes of Mt. Siswa when we camped there
(20/7/15), and a fortnight previously a lioness had been
wounded almost on the very spot where our tent was pitched.
When on picket at Longido West (22/11/16, etc.) it was a
common occurrence to hear them roaring. When in open
bush country near Moshi (15/3/16) a sergeant rising one
morning saw a lion standing, looking at the bivouac, some
four hundred yards away. Other observers took it to be a
leopard, however.
COLLECTED OR KEPT IN CAPTIVITY
51
At Gulwe, near Mpapua, where large herds of cattle were
kept for military supply, they were a great nuisance. A
lioness shot herself in a gun- trap one night, some two hundred
yards from the open hut in which I slept. This was the
fifth lioness obtained in a fortnight (20/4/17). The natives
gathered round as it was being brought in, and one old crone
mumbled ‘ Lions are just like men, they send the lionesses
into the trap first and so they never get caught.’ There was
a general laugh at this, but another interpretation occurred
to me. The lionesses might be greedy in pushing forward,
and the lions politely standing aside reaped virtue’s own
reward.
Felis pardus suahelica, Neum. — At a military grass-cutting
camp at Ngong a trap was set for leopards. One was caught,
but during the night was attacked by two hyaenas, who bit
off its tail and snatched a mouthful of flesh from its haunch
(20/9/15). Leopards were very plentiful at Longido West in
January 1916. One afternoon a sergeant of the E.A.M.R.
discovered one lying under a bush in a donga some nine feet
below him. It made off immediately. Their coughing cry
was to be heard by the pickets almost nightly.
One morning at Morogoro the writer received a message
asking him to come and shoot a leopard which had been
trapped near the German Mission. On arrival, however, I
was told that the leopard had made off. At daybreak it
had dragged the heavy trap on to a large rock, where it lay
growling and worrying at the trap until 8.30 a.m., when it
got free ; it bounded off the rock to the ground some twenty
feet below and went off on three legs. The trap had plenty
of fur on the jaws and plainly bore the marks of teeth and
claws (19/10/17).
It was also at Morogoro in the bush, just before sunset,
whilst I was taking aim at a cuckoo, in line with the sights
but at a distance of sixty yards, a half- grown leopard or large
serval leapt down from a blasted tree on one of whose branches
it had apparently been lying. On running to the spot its
spoor was found, and about fifteen feet from the tree were
also verjr fresh tracks of a bush- buck which had been pawing
up the ground, presumably to get at some roots.
52
NOTES ON EAST AFRICAN MAMMALIA
Acinonyx jubatus, Schreb, — On 16/7/15 a cheetah was
put up at very close range near the opening gorge of the
Kedong Valley, Naivasha end. It had been lying in open
country with very little cover, but we did not see it until
almost upon it. A paragraph appeared in one of the local
papers about a pair of captive cheetah cubs — ‘ our repre-
sentative who called upon them found them to be charming
little fellows, allowing themselves to be handled freely,
sheathing their claws.’
HYmmvm
Hyaena, sp. — One of the compensations of picket-duty at
Longido West was to see the hyaenas at daybreak disputing
for, or gorging on, the offal which was left on the killing
ground for them to clean up. One of the creatures passed
within six feet of me on its way to supper one night. When
taking a message across country near Mkomasi I met a hyaena
at 8 o’clock in the afternoon, bright sunshine ; a scrap had
taken place just before lunch, and a body which I had passed
ten minutes before was probably the cause for this activity.
When staying at West Kenia my host cautioned me not
to put my boots outside the guest-hut at nights, as the hyaenas
would surely carry them off. He related how on one Christmas
Eve he heard a noise outside. On opening the door an
animal ran past ; turning back for gun and lantern, he after-
wards walked round the house, and in so doing came suddenly
upon a large hyaena eating the leg of an eland which it had
pilfered — it was then but thirty feet from the door. For
some seconds it seemed dazed at the light and merely crouched
over the meat, but recovering its senses bounded away, and
as it did so he shot it dead.
Canids
Jackals were often met with, but no specimens collected.
They appear to be very curious creatures. On one occasion,
having shot a bustard on West Kenia plains, I was kneeling
beside the bird, plugging nostrils and beak with wool. Some-
COLLECTED OR KEPT IN CAPTIVITY
53
thing caused me to look round, and there stood a jackal
scarce fifty yards away, regarding me intently. It cantered
away only when I stood up — this occurred about 10 a.m.
Another time at Lumbo, B.E.A., I had forced my way through
some thick bush and was silently watching some waterfowl
on the lagoon ; a slight noise behind me caused me to spring
round in time to see the disappearing flank and tail of a
jackal not ten feet from me.
Mustelid^j
Mellivora sagulata, Holl.— The only occasion on which a
live ratel, or honey badger, was seen was at Longido West
(22/2/16). About 2.30 a.m., whilst I was on picket on an
‘ ant-hill,’ a small animal which I mistook for a ‘ Scotch
Terrier ’ came trotting past. It was brilliant moonlight at
the time. Some hours later, when taking my second watch,
it returned and came sniffing up to within five feet of my
blankets and within ten feet of a sleeping man. At Dodoma
(4/12/18) two were caught in a trap set for leopards. I saw
the skins, which were drying.
VlVERRIDiE
Civettictis civetta orientalis, Matsch. — It is curious how a par-
ticular species may not be met with in a particular locality
for a long time, and then for a short period specimens crop
up continuously. I was in the Morogoro district for a year
before meeting with a civet, and then two specimens came
in on the same day, having been killed by motorists in different
districts. The male, which had been shot, measured 44§ inches
from nose to tail, and its stomach contained skins of mango
fruit (?), warningly coloured grasshoppers, many maggots,
and parasitic worms. The female kitten had been run over
by another car, and measured 31 \ inches.
One brilliant moonlight night at Morogoro (27/3/18) a
terrific caterwauling arose in the bush quite near camp. The
boys asserted that it was caused by civet cats (‘ Eungo ’) fighting.
I got very near to them, when the outcry ceased as suddenly
as it began, and I suppose they must have heard me. In a
54
NOTES ON EAST AFRICAN MAMMALIA
mangrove swamp near Frere Town, Mombasa (20/5/18), there
was a great outcry of natives and barking of dogs most
evidently hunting something. I arrived just after the kill,
for a civet cat had been hunted down and battered to death
with clubs and sticks. The boys said that it had been after
poultry, that the cackling of the fowls had started the dogs
barking, and I presume the barking of the dogs had set the
natives yelling. In November, 1918, I purchased two civet
kittens from a native at Morogoro ; they could just walk,
and rather reminded me of collie pups, their feet being huge
and out of proportion to their bodies. They would frequently
stumble in their walk ; when first received they hissed like
snakes when approached, and gave vent to startlingly sudden
spitting noises ; after a few weeks this was given up and they
became perfectly tame. I was too busy to look after them at
the time, and so passed them on to someone who wished to
take them home. Another man I knew had a civet kitten
of the same age as mine and at the same time ; judging by
the three records, therefore, the young are born at Morogoro
about the beginning of November.
Genetta, sp. — At Morogoro (10/12/17), on the slopes of the
Uluguru Mountains, are many fine deep dongas. In one of
these, nearly choked with euphorbias and other undergrowth,
my boy saw a gennet cat leave its earth. He was sent into
the donga to drive out anything that might be there. On
hearing his cry not to shoot I came down from the top end
and reached the spot where he was already clambering up
the almost vertical cliff-like bank. On reaching the hole,
and after a few minutes’ work of breaking away the entrance,
he drew forth a scratching, spitting kitten which he dropped
into his haversack ; a second was captured in like manner.
The earth, he said, was unlined but perfectly clean ; it
consisted of a circular chamber and two belt holes beneath
the roots of a tree that had long since disappeared. Whilst
he was climbing up through the undergrowth of the further
bank one of the kittens escaped from the haversack and got
away in the long grass : we could hear it crying — more like
a squeak than a mew — and heard the mother coming towards
it, but it w’as already too dark to see anything.

55
For the first forty hours the remaining kitten hunger- struck,
and when one approached turned on its side and spat and clawed.
I must confess that I was somewhat afraid of it, its spitting was
so alarmingly sudden and explosive ; realising that if this con-
tinued we should never come to terms, I picked it up and
allowed it to bite, which I found was little more than a pinch,
as its teeth had only milk dentition. A little rubbing of its
ears and fore- paws eased its mind considerably, and it settled
down inside my shirt whilst I wrote up these notes — this had
its disadvantages, for, though beautiful and leopard- like in its
markings, it teemed with ticks and fleas. Introduced to the
baby lemur it nosed up in quite friendly fashion ; but the
lemur, though only half the size of the gennet, reared up on
its hind feet and then flopped on to the gennet’s nose. This
occurred each time they were brought together.
The kitten refused to touch meat, and milk it would only
take if sweetened with sugar to the consistency of treacle.
She drank water readily, though there was none anywhere in
the neighbourhood of the donga where she was found. She
was very fond of jam, and ate the contents of birds’ eggs.
On December 27 a native caught an adult gennet, which
was brought to me with a cord very tight round its neck
and caged in a piece of wire- netting. On opening this there
was a great exhibition of teeth and claws, accompanied by
spitting. Just as it was being introduced to its cage it clawed
the boy who was holding it ; he promptly dropped it with a
yell.
We surrounded the grass hut in which it had taken refuge,
and searched the grass walls carefully ; finally it was detected,
and one native called out triumphantly that he had secured
it in some towels. Once more, with greater caution, the
door of the cage was opened and the creature tossed in, towels
and all. Too dazed with such unusual treatment to move—
there lay my gennet kitten on its head. I picked it up and
comforted it, and the hunt for the old cat commenced once
more and ended in its capture.
The cage in which the cat is put is 12 feet long by 4 feet
wide and 5 feet high. The kitten has been put in with the
cat, but gets out every night through the large wire mesh
56
NOTES ON EAST AFRICAN MAMMALIA
and wanders about till daybreak. She resents being picked
up, but once settled on one’s lap she will sleep contentedly
enough.
She frequently comes into my bell-tent at night and
climbs up between the outer and inner canvas in search of
insects, which are attracted by the light. One night she ate
a large cricket which I had deviscerated and re- stuffed with
arsenic- saturated wool and carefully set ; this apparently
disagreed with her, and she vomited up the lot within a few
feet of the setting board. It is very pretty to watch her
pounce on a locust, which is a favourite article of diet with her.
On the night of February 12-18 there was a great deal
of caterwauling and fighting outside, and in the morning I
found the gennet kitten dead and draggled with mud : it
had apparently been killed by stray domestic cats. It
measured 19 inches from tip of nose to end of tail. The
old cat made a journey from Morogoro to Nairobi, living on
‘ bully ’ a good part of the way. In Nairobi it was given
to a lady, who had it for a year or more ; her little girl suc-
ceeded in taming it so that she might handle it ; the gennet
would not let anyone else come near it, however. Finally,
its cage door being left open, it escaped, probably to make
trouble for systematic mammallogists making subspecific
local races.
Nandinia binotata arborea, Heller. — A specimen of this
forest cat was shot by a sergeant of the E.A.M.R., in Meru
Forest, near Arusha, Tanganyika Territory (12/4/16).
Mungos mungo, Gmel. — The banded mungoose, until
recently better known as Crossarchus fasciatus, was common
at Lumbo, B.E.A., though not in such numbers as the sub-
species at Morogoro, G.E.A. The packs at Lumbo rarely
exceeded five or six individuals. One burrow was found at
the roots of a tree, another beneath a huge rock on the shore,
others again were living in the termite heaps. The cry is a
very bird- like note emitted when hunting; hunting consists
in turning over stones and scratching for insects in likely
spots. When captured by the scruff of the neck these animals
squeal deafeningly.
A female and young one which were brought to me alive

were in a very emaciated condition, being literally riddled
with what I took to be the larvae of the Tumbo Ely ( Cordy -
lobia). The maggots after evacuating for purposes of
pupation left great raw holes. The tail of the adult was
particularly infested.
The largest male and female taken measured 22j inches
and 23J inches respectively, from tip of snout to end of tail.
Male, 870, 210, 67, 28. Female, 860, 280, 70, 25.
Mungos mungo colonus, Heller. — Several specimens of this
race were taken at Morogoro, where it was particularly
plentiful. Four records were made of birth and age of young.
A female with very small foetus was found (11/11/17), a
single naked young one no larger than one’s thumb in a nest
(7/8/17), an unweaned kitten in the road (3/11/17), and two
kittens able to run about and feed themselves (3/3/18). The
notes at length are as follows : —
(7/8/17.) ‘ In clearing some land near here the boys found
the dead body of a female mungoose considerably decomposed ;
near by was a nest containing a young one about the size of
one’s thumb. I kept this alive for three days on diluted Ideal
milk, but though it drank eagerly it appeared to pass no ex-
creta, and the stomach increasing in size, it finally died. I
intended to preserve it but was frustrated from doing so by an
adult Mungoose, which, in its daily cruise about the camp in
search of tit- bits, was seen to carry it off.’
(3/2/17.) ‘ Eeturning home about 6 p.m. after a heavy
downpour of rain which had left the road in a semi-flooded
state, I noticed a dozen men watching what I took to be a
kitten ; it looked very forlorn and uttered a shrill, piercing
cry not unlike the note of a canary. On closer inspection it
proved to be a very young mungoose no larger than a rat and
which had presumably been washed out of some drain. It ran
well, and when covered with a towel bit its captor fiercely
through it. Carrying it to my quarters, I provided it with
milk, raw liver, and boiled meat, none of which it touched
excepting the milk in which it lay down. All the time it per-
sisted in its monotonous cry or whistle.
‘ The immediate effect of its cries was to elicit an answering
call from a stray cat downstairs — such a cry as a cat answers
58
NOTES ON EAST AFRICAN MAMMALIA
her kittens with. Presently she came up through a hole in the
floor and approaching the box with caution, stood upon her
hind legs and viewed the prisoner through the wire netting.
As it continued to cry all night and was a nuisance to the
neighbours, I chloroformed it in the morning. Male, 9| inches,
of which Bf inches was tail.’
(8/3/18.) ‘ Purchased two young mungoose which had been
found running about by a native child, they followed to heel
in the most remarkable manner and in this way accompanied
my boy home for a quarter of a mile. In build they are
rather otter- like, but in size no bigger than a large rat. When
introduced to the monkey, they sat up on their hind legs with
their short fore- paws dropping on their stomachs — meerkat
fashion — then they spat explosively and pretended to bite.
They are very quarrelsome ; fighting over tit- bits of food.
Though so small they are well able to look after themselves and
spend their time running hither and thither, rooting about or
digging up insects with their strong claws.’
Except when fully fed they keep up a continual bird-like
chirping and cheeping. Except for the first week I did not
shut them up at nights, during the day they were always free
to wander about, but never seemed to go outside a radius of
200 yards from their sleeping box. After three weeks they
made up to the monkey, and it was a pretty sight on a hot
afternoon to see the three of them lying together in a shady
spot.
A dead cobra being brought me, I gave the body to the
mungoose after first cutting off the head. It was most amusing
to see the caution with which they approached it and sprang
back, apparently with the object of ‘ drawing it ’ if alive.
The bristles on their otter-like tails stood up. When sufficient
courage had accumulated, they first attacked the tail which
they worried and bit and afterwards gorged themselves on the
entrails.
Their method of dealing with eggs was most interesting.
They would roll the egg towards some wall or solid object.
When near enough it would be taken up in the fore-paws and
held against the chest ; standing on its hind legs, the creature
would then waddle a little closer to the wall, turn its back upon
COLLECTED OK KEPT IN CAPTIVITY
59
the wall, straddle out its legs and suddenly fling the egg between
them against the wall with the result that the egg would be
broken and they could devour the contents. Given a large
cockle-shell they went through the same performance, but
never succeeded in breaking the shell ; they grew very excited
and would steal the shell from one another and each try their
hardest.
The attitude of adults to snakes was interesting ; a dead
snake they would always devour, a live one aroused interest,
but they were excessively cautious. Even when a harmless
species such as a brown house snake was turned out in the open
the mungoose would treat it with respect, running in to bite at
the tail and jumping back before the snake had time to strike.
In the stomach of one specimen examined were the following
— three frogs, two centipedes, four slugs, a carabid beetle, cock-
chafers, cockroaches, locusts, grasshoppers and a large spider.
This gives some idea of the omnivorous nature of their dietary,
and shows how useful they must be in assisting to keep down a
lot of undesirable insects. The quantity consumed by one
mungoose in the course of a day must be very large.
There were some peculiar parasitic worms in the intestines
of a male specimen that was shot. These were Porocejphalus
sp., a worm usually found in pythons but which has also been
found in man (native, Dar-es-Salaam, 1918). In the case of this
mungoose it is probable that it had eaten a snake, and so in-
troduced the parasite into its own economy. Fleas and ticks
were very abundant in the fur of most specimens.
Herjpestes sanguineus ibece, Wrought. — A single specimen
was obtained at Msiha River, Makindu, G.E.A. (Shell Camp).
Herjpestes mossambicus, Matschie. — Four specimens were
shot or dug from their burrows at Lumbo, B.E.A. It is a
handsome species, of general rufous colour with black-tip to
the tail. The head has a particularly evil appearance, due in
part to the fierce eyes and very small ears. They are expert
climbers, and remind one of martens when so doing. A pair
kept in confinement were as fierce and implacable after a
month’s captivity as on the day they were caught. During
this time they were fed upon bullock’s flesh cut into very small
pieces. They drank water. Their glossy coats testified to
60
NOTES ON EAST AFKICAN MAMMALIA
their good condition and their stomachs were very full when
dissected. The largest male measured 20§ inches (284, 240,
57, 28) and the largest female 21f inches (800, 250, 55, 23).
Helogale ivori, sp. nov., Thos. — These small mungoose must
be very abundant, though more often heard than seen. They
make quite a noise as they run about in the undergrowth
hunting for the insects upon which they feed. Immediately
they become aware of the presence of anyone in their vicinity
they make off. They live in the holes of termite-heaps, which
are such a feature of the country around Lumbo where they
were met with. They are fond of lying near their holes and
sunning themselves in the early mornings. Four and five
respectively were dug from two of these holes one morning.
In one instance they were found inhabiting the same hole as a
large lizard ( Gerrhosaurus major) ; a still stranger companion
was a five-foot snake ( Bhamjphiojphis oxyrhynchus) which was
taken out of the same burrow as two mungoose.
No nest is made, and the female brings forth her young in
the bare earth during the month of October and possibly
November. A litter consists of four or five young (three ob-
servations) ; when born they measure male, 69, 32, 7, 5, and
female, 65, 33, 12, 5. The young have a bird- like cry. In
captivity they were kept on an almost exclusively meat diet.
They showed a great liking for crickets which they would snap
out of one’s fingers in their eagerness. Crabs were also relished,
though not to the same extent. Butter they would not touch ;
a single individual developed a liking for jam ; cheese, chicken
and eggs were taken ; the latter are broken open in the same
way as practised by the banded mungoose.
On an underlined sand snake ( Psammophis subtceniatus)
being introduced into the cage, it was immediately pounced
upon and crunched up, the whole of it was apparently eaten by
the one mungoose which growled like a cat continuously and flew
at its mate whenever she ventured near, which she did again
and again. Lizards were also seized with avidity. This
mungoose is in the habit of sitting up on its haunches with its
fore-paws resting on its stomach after the manner of a meerkat.
They also showed great expertness in climbing the shrub which
was put in their cages.

61
The largest male measured 14J inches (242, 135, 40, 20),
and largest female, 15 inches (240, 140, 40, 20). Over twenty
specimens were obtained.
Tumbo fly had infected one specimen, but the remainder
were apparently very free from parasites, they kept themselves
very clean externally, but one rather shirked the examination
of their stomachs as these smelt so strong.
SciURIDiE
Paraxerus flavivittis mossambicus, subsp. nov., Thos. — A
long series of this new sub-species was obtained at Lumbo.
It is possible to live in close proximity to these squirrels without
being aware of their existence, so expert are they in climbing
round the trunks of trees, flattening themselves out on branches
and making themselves scarce generally. They are extra-
ordinarily fond of heat ; soon after sun-up they crawl out on a
branch, and flattening themselves out to absorb all they can,
they bask like lizards. Young ones would lie at 3 o’clock in
the afternoon on a table in the full glare of a sun that quickly
rendered metal tools too hot to handle. Whilst in captivity
adult- caught specimens seemed but little tamer after three
months’ confinement, young specimens go to the opposite
extreme and seek human companionship.
The young are brought forth in September (three ob-
servations), the nest is composed of a mass of fine grass and
is placed in a hollow tree-trunk. Young taken on October 4
from such a nest were fed on milk for the first few days, then
they were given sugar and raw oatmeal, and in due course
ground-nuts, potatoes, bananas, jam and milk puddings. The
favourite food was bananas, over which they would grow quite
excited. Natives assert that they gnaw holes in clothing (!),
on one occasion I disturbed one in my tent.
After the first three days in captivity the young ones were
allowed their liberty and slept wherever they liked, above all
they preferred a sack of kapock. They would burrow into
this and not re- appear until 11 a.m. next day. It is difficult
to know how they could breathe in such fluffy stuff. In the
mornings they would climb a mango tree and bask in the
62
NOTES ON EAST AFKICAN MAMMALIA
sunshine until called down by the sight of food. A plantain-
eater was kept in a large cage on the ground and they would
get in through the wires, climb into the porridge plate and
sprawl about eating heartily. They were but little larger
than the plantain- eater’s head, yet the bird never molested
them, but would continue feeding with the uninvited guests.
On another occasion one of them was plundering the food
of an old male squirrel, when he came down from his sleeping-
box, approached slowly, then suddenly snapped viciously at
the intruder. The little creature only moved slightly so that
he missed his aim ; this was repeated a second time with like
result. Then the old squirrel, apparently ‘ liking its style,’
pounced upon the mite and gave it — a licking from head to
tail.
The largest male measured 13 J inches (176, 160, 40, 15),
and female 13f inches (175, 175, 40, 18). Average measure-
ments of fifteen specimens of both sexes was 162, 159, 39, 17.
Paraxerus ochraceus, Huet. — Specimens of this squirrel were
collected at Morogoro, Dodoma and Kongwa. The largest
specimen came from the last-named locality, and was a female
12J inches in length (174, 152, 35, 21).
Paraxerus ochraceus aruscensis, Pagen. — Collected in Mt.
Meru Forest, a few miles from Arusha. This species is also
common at Mombasa and Frere Town where specimens were
taken.
Paraxerus ochraceus jacksoni, De Wint. — The common
forest squirrel about Nairobi. Attracted by the cries of some
birds on the outskirts of the Parklands Forest, one of these
squirrels was observed turning round and round a branch like
a Catherine wheel, though more slowly. It made off immedi-
ately on being approached, and the birds also scattered, to
continue their outcry at a more discreet distance ; a puff
adder, however, was found lying on the ground about eight feet
from where the squirrel had been performing. Probably the
squirrel had seen it also, and was showing his objection to the
disquieting discovery in his own fashion. The largest specimen
was a male measuring 14 J inches (180, 180, 38, 19).
Xerus rutilus saturatus , Neum. — Was very common in the
neighbourhood of Longido West. It was probably the same
COLLECTED OK KEPT IN CAPTIVITY
63
ground squirrel that was seen at Mbunyi and Mkomasi. A
Longido female obtained on January 31 measured 17f inches
(24 2, 216, 53, 18), and had two foetuses in uterus, nothing but
green leaves in stomach.
CRICETIDiE
Taterona leucogaster, Peters. — Three specimens of these
light brown rats with white bellies were dug out of ant-heaps.
The largest specimen was a female measuring 9| inches
(140, 154, 35, 20), the biggest male was only a little shorter
in the tail.
Taterona swaythlingi, sp. nov., Kersh. — Common at Moro-
goro, especially under sisal hedges, in the clearing of which a good
many specimens were obtained. The largest male measured
12J inches (180, 128, 37, 22), the largest female 12J inches
(140, 171, 34, 21).
Taterona taborce, sp. nov., Kersh. — Obtained at Tabora, all
the specimens had their ears affected with a mould or lichen-like
parasite.
Murids
Steatomys loveridgei, sp. nov., Thos. — A single specimen of
this fat mouse was obtained at Lumbo, 1/10/18. It measured
4§ inches (male 77, 35, 15, 18).
Battus fumatus, Peters. — Very common at Morogoro, where
a large series was obtained. They were commonly found
beneath any object in the bush or fields, particularly near
dwellings.
Battus couclia, subsp. — This species was also met with at
Morogoro, a male was found in its nest in a hollow tree at
about four feet from the ground, it bit fiercely on being picked
up. Another specimen was taken as it emerged from a hole
in the ground.
Battus couclia panya, Hell. — Very common at Nairobi, where
it is so bold that it will come out and feed in broad daylight.
Leggada bella, sabsp. — Taken at Dar-es-Salaam. A single
male measuring 3§ inches (48, 37, 11, 10).
64
NOTES ON EAST AFRICAN MAMMALIA
Leggada bella, subsp. — Several specimens were taken at
Morogoro. Two females measured 4 inches (53, 46, 12, 9).
Leggada bella, subsp.- — A pair were taken at Tabora. The
male being just under 4 inches (55, 45, 12, 9), and the female
3f inches (50, 42, 12, 8).
Arvicanthis abyssinicus neumanni, Matschie.— This sandy-
coloured rat was very abundant at Dodoma in the thorn- bush
and in open spaces in the village. It runs about during the
heat of the day, but bolts into its burrows at the base of a
thorn- bush when anyone approaches too close. I was told
that twenty- four were captured in four wire traps set in a
store during the course of a day. One of the specimens col-
lected had three legs afflicted with what appeared to be elephan-
tiasis. Some three dozen specimens were taken ; of these the
largest male measured 10f inches (150, 113, 24, 17), and female
91 inches (125, 110, 25, 15).
Lemniscomys griselda rosalia, Thos. — At Morogoro a few
specimens of this striped rat were taken, but the animal was
far from common. A male measured 10 J inches (21, 140, 26,
19). A female measured 9| inches (115, 130, 25, 19).
Grammomys surdaster, Thos. and Wrought. — At Morogoro
and Lumbo. In both cases the animals had built their nests
within those of weaver birds at a good height from the ground.
Male measured 10 inches (108, 146, 48, 16).
An immature pair were taken in their nest which was con-
structed within that of a weaver bird, situated in a bush at a
height of 5 feet from the ground. They were kept in cap-
tivity for a week and would eat almost any kind of food.
The male escaping on September £0, 1918, the female was
chloroformed. That the male was still in the vicinity of the
tent was evidenced by sundry depredations. Exactly a
month later this rat was taken in a fold of the tent in which it
had gnawed a large hole and carried up fine shreds of grass
wherewith to make a home for itself.
PEDETIDiE
Pedetes surdaster, subsp. — Jumping Hares were to be found
outside Morogoro. At Tabora a specimen was caught by some
COLLECTED OR KEPT IN CAPTIVITY
65
natives after a heavy downpour of rain which was supposed
to have washed it out of its burrow.
Bathygerid^
Heliophobius argenteo-cinereus, Peters. — This large grey mole
rat was occasionally brought in by the natives who dug it up
in their gardens. A male measured 6J inches (168, 6, 29, 0),
a female was 5| inches in length (188, 7, 29, 2).
Hystricid.®
Hystrix galeata, Thos. — Six porcupines were killed in the
course of a few weeks on an estate at Muthaiga, near Nairobi
(June 1915). They do a great deal of damage, eating quan-
tities of maize cobs, which they obtain by gnawing through
the stem until the plant falls. When visiting at the house
one day, a bull- terrier came in bristling with quills, blood
running from his right shoulder, and lame in his right leg. It
was thereupon decided to unearth the offender, and four
kerosene tins of disinfectant were prepared and poured down
one of the holes or entrances to its burrow. It did not bolt
from the other outlet, so both holes were blocked up and a
dozen natives sent into the thick scrub behind to beat it out,
whilst a gun guarded the holes.
After a wait of nearly twenty minutes there was a grunt
and a rush through the undergrowth, the beast suddenly
appeared and dived into one of the entrances to the burrow,
two dogs who were following at his heels were soon on top.
A great pandemonium ensued, dogs and quills were falling
in all directions, growls, yelps, squeals striking on the ear
simultaneously defied description. In less time than it takes
to relate, however, the porcupine scrambled out and made
away through the cover, we in pursuit ; but it made good
its escape.
At Dodoma a well- used earth was found beneath a large
rock, and a friend meeting the porcupine early one morning,
shot it.

Leporidje
Lepus capensis abbotti, Holl. — A single specimen was ob-
tained near Dar-es-Salaam. Male.
Lepus whytei, Thos. — Half-a-dozen leverets were brought
to me whilst at Lumbo, between July 10 and October 1. The
young are evidently brought forth during the whole period,
possibly all the year round. Two leverets were found in one
form, usually they were found singly, as if only one were
produced at a birth.
They make delightful pets, but are only short-lived in
captivity. Four very small ones succumbed to diarrhoea,
though their Ideal milk was diluted with six parts of water.
Their milk was fed to them through a glass blow-pipe, one end
of which was retained in the writer’s mouth so that the fluid
should not flow too fast ; they sucked eagerly at the tube, and
one individual, if shewn the tube, would hop about the table
after it. This specimen, after being fed a week upon milk, took
to nibbling grass, and appeared to be doing all right, when an
accident occurred. Whilst ‘ out to grass ’ in charge of a native,
it bolted. On overtaking it the boy pounced upon it as it squatted
in a clump of grass. One of the blades, presumably, punctured
the eye. From that time it moped, refused food, and died on
the third day after.
Another was kept for over a month fed upon a mixture of
tea leaves and stiff porridge, with the addition of greens when
obtainable. Its death was also an unusual one. Its run,
which was 8 feet long by 2| feet broad, was invaded one
night by ants, which apparently attacked eyes and mouth ; in
the morning it was found dead with the lips badly eaten away.
When out in the bush they were not often seen — possibly one
per week. They appear to be quite unable to rid themselves
of burrs when these become attached to the fur.

Potamochoerus choeropotamus, subsp. — At Morogoro, on
January 9, 1918, some natives brought me five young wild pigs,
characteristically striped. The mother had left them under
a bush in a rubber plantation. They averaged 14 inches in
length, of which would be tail.

Procaviid^j
Procavia frommi, Brauer. — Rock Rabbits were common,
both at Dodoma and Tabora, where they were found on rocky
kopjes. They might often be seen on the branches of trees as
well as on the rocks. They always carry a lot of worms in the
stomach, both Nematode and Cestode. The following were
found in one Dodoma specimen : — Crossophorus collaris, Hempri
and Ehrb, Anoplocephalus spatula v. Linst., Inermicapsifer.
The largest male (Tabora) measured 17f inches (450, 0, 62,
29), and largest female (Dodoma) 18^ inches (470, 0, 67, 85).
Procavia, sp. — When at Morogoro I saw some skins
of a Hyrax exposed for sale in a Greek’s shop. I inquired
where they were obtained and learnt that they came from near
the top of the Uluguru Mountains. I made it known among
the boys that I would be glad to purchase specimens if brought
in the flesh. It was more than a year before a specimen was
brought to me. It was a female measuring 23| inches (595,
0, 79, 82). In the uterus was an embryo 88mm. long, with a
coccyx 1mm. in length.

Morogoro. He had inflated views of its value and wanted 27s.
for it, so that I did not purchase it. He returned on the 15th
inst. and sold it to me at a more reasonable figure. It was well
over three feet in length. When all was quiet it would cautiously
unroll, revealing its long pointed nose ; if nothing happened
it would then begin to trot away with the fore- legs, looking
painfully awkward, almost as if the creature were trying to
walk on its wrists, nevertheless it managed to travel fairly
quickly. It rolls up immediately on being disturbed, and gives
a little snort of annoyance ; if you then attempt to pick it up,
its plaited tail flies round with good force and then returns to
protect the head. I spent two hours in making a run secure —
as I thought ; twenty minutes after being put in, however, it
had disappeared, and was not to be found, though forty boys
were out looking for it with lanterns. On February 1 a young
68
NOTES ON EAST AFRICAN MAMMALIA
specimen about 18 inches in length was brought me, but I did
not purchase it.
Orycteropodidje
Orycteropus cethiopicus, Sund. — Aard Yark, ant-bear or
earth- pig, as they are variously called, were common at Moro-
goro and Tabora, but never seen unless dug for. Having
located a burrow at Tabora on December 11, 1918, I set eight
boys to dig it out at 7 a.m. They kept on till I joined them at
4 p.m., having knocked off work for an hour at noon. They had
dug a furrow about twenty feet long and varying in depth from
six to ten feet, they reported having twice caught sight of its
tail. I kept them working fast in relays and presently saw
what I took to be a foot throwing back the earth. I fired at
this, but it proved to be the tail which is extraordinarily thick
and an aid to the feet in throwing out the soil.
After another half-hour’s digging, a boy seized the creature
by its tail, two more boys held on to the first boy’s legs, never-
theless, he was slowly but surely drawn into the burrow up to
his waist. Muffled cries proceeded from him and finally letting
the animal go he was pulled out fairly smothered in the loose,
sandy soil. Digging at once went on, and when the creature was
again sighted ropes were attached to the two hind legs, these
were used to draw it like a refractory cork from a bottle, it was
not long before one was snapped, but the creature came out,
plunging like a tethered bull. To my great surprise it was
about five feet in length, and a couple of feet in height. I fired
at it at a distance of twenty feet with No. 5 shot from a 12 -bore,
the shot hit it in the neck, but it took no notice except for a
sudden plunge. A boy then approached and brought down
the heavy end of a mattock on its head with full force. This
resulted in the animal rearing up on its hind legs, snapping the
second rope, after which it broke away across country at a
peculiar yet fast gallop. It went to earth in a burrow on the
railway embankment, and as we arrived at the spot, all that
was to be seen was a few handfuls of earth being flung out.
If it had not been that the creature was possibly wounded
more severely than was apparent, I should have liked to have
ceased the chase and given it its well-earned liberty. Quite
fifty natives had collected by this time and eager hands were

soon at work digging, when suddenly the ant-bear turned and
charged out of the burrow, natives fell over in every direction
and got in each other’s way. A Kavirondo brought his club
down on the animal’s head which only had the effect of
breaking the club, the animal continued for a hundred yards
and went to ground in another burrow.
Someone seized its tail and hung on whilst others attempted
to fasten ropes, boy after boy fell back to spit sand from his
mouth, and clear it from his eyes and hair. The sand continued
to be thrown out in powerful jets. A rifle which had been
sent for arrived at this juncture, and a couple of shots killed
the poor creature without further delay. It was found to
measure 68 J inches of which 28 \ were tail. (Male 1140,
590,225, 175.)

An Impression
By R. Harger
An hour before an African sunset on the coast near the
Equator. This afternoon there was heavy rain which lessened
to a drizzle and has now ceased. The air is still, damp,
and quite chilly in comparison with the pre-storm midday heat,
which has left the earth much warmer than the atmosphere.
Thus, already a slight haze is produced which is noticeable
even within fifty yards. The light is subdued. Excellent
conditions for certain insects to be on the move, especially
those which travel on legs alone.
What a world to tackle for those whose eyes are, maybe,
but one-sixteenth of an inch or less above the ground ! — eyes
which perhaps are not very keen of vision or long of focus.
Along a slight track, worn by native feet, are many
obstacles. Many small pools of water held and bordered by
fine mud. Here a sodden and tangled mass of grass stems.
There a small washout still holding water held back by dams
70
THE EAID OF THE PONERA
of dead leaves. Fallen from the trees above are many sticks
partially embedded in mnd. On the adjacent land untrodden
by human feet, these obstacles are greatly increased in
magnitude and number. Here the termites (white ants so
called) revel in luxury.
Keep your eyes on the clearer pathway. Wait patiently ;
something may appear. What is that ? About thirty feet
away on the pathway is a blackish streak a few feet long. A
disturbed nightjar diverts one’s attention fora few moments,
but look again. The streak is not so long as it was. It is
moving. A slight undulation in the ground has apparently
shortened its length. Go closer. It consists of insects. Go
closer still. They are black ants of equal size, on the march
five or six abreast, in irregular formation of a column about
five feet long. Half a dozen scouts are three or four inches
ahead of the main body.
Stoop and puff a breath on the middle of the column.
It expands slightly, but quickly regains formation. Go ahead
and put a stone right on the line of march. A slight check
results and the column winds round it. Go ahead again,
and with a stick score a rut right across the track. The
leaders stop. The head of the column slightly expands.
Willing investigators dart out. No danger. The ants pass
through the rut and regain formation, the scouts constantly
falling back and being replaced by others.
We must cease to worry them. Evidently they are moving
with set intention, some definite business ahead. What can
it be ? Let us wait and see. There they go at a steady pace
of about two yards a minute, every individual well separated
and self-reliant, yet forming part of a body which is perfectly
self-contained. A small brown field cockroach carrying a
cachet of eggs darts out from a grass clump, attempts to cross
the path, nearly collides with the column and darts back. The
ants take no notice of her. Without doubt they are after
better game, the search for which concerns every member of
the party. Watch their antennae, which are held with points
held downwards, but are constantly raised for a second or
two as if feeling for some wireless message.
A few yards more of orderly march and then— the leading
members hesitate for a moment. The head of the column
THE RAID OF THE PONERA
71
opens out. Instantly the formation is broken. Every mem-
ber breaks off almost at right angles to the line of march
at much increased speed. To the human eye there is nothing
to account for this rapid dispersal. The direction is towards
a small open space where lie sticks and prone tangled stems
of sodden grass, five or six feet distant from the pathway.
On reaching this every ant uses his jaws. Many curve
their bodies in exerting all their strength to remove bits of
mud and vegetation. Other jaws appear from below— yellow
jaws. Termites are here, hence the felled stems of grass.
The fight has begun. The black ants quickly open up the
white ant runs, which, owing to the recent heavy rain, had
no visible surface earthworks. The termites, lovers of
darkness, are seized as they come to the surface. Some
manage to leave the burrows, and to slowly wander on the
surface with uplifted jaws in readiness for the downward
stroke, but very soon they are seized bodily by black jaws
at the side or rear. At the holes a few pairs of yellow jaws
have been buried in black bodies which are curled in the
death-struggle, for the grip of the termite is a terrible grip.
Black ants are scouting the vicinity and exposing more
passages. The fight has now lasted for about three minutes.
The combatants are spread over five or six square feet.
Suddenly, as if by pre-arranged signal, the outlying raiders
cease their work. They feel the air for a moment, and then
concentrate on the main body of blacks which are already
moving towards the pathway whence they came. The fight
has ceased. The return journey has commenced, but the
struggle has not been entirely one-sided. Five or six black
bodies can scarcely move. Perhaps as many more, sticky
with termite secretion, have been dragged underground.
Nearly every black ant carries a white victim, now motionless
in black jaws. Nearly, but not all, for on reaching the path-
way the column reforms, heading whence it came and led
by unburdened scouts. A few others flank irregularly. The
remainder gather in the rear. The main body carries the
spoil. All resume the former steady marching pace.
But observe : away back some few feet is a black straggler
who is evidently endeavouring to rejoin the column. His
effort is great, but his pace is slow, like a very lame horse in
72
THE MIGRATIONS OF BUTTERFLIES
a hurry. Something is attached to one of his hind legs. The
writer stoops to investigate, and with a bit of grass holds the
obstruction to the ground. It is an atom of dry vegetation
attached by a viscid substance, perhaps termite secretion.
The ant struggles, frees itself, and greatly increases speed
towards his retreating companions. He has a long distance
to go, but manages to join up. The column is now well away
on the homeward journey at a steady pace, and turns from
the path into the grass without hesitation. The dark stream
enters long grass. The sun has set, and the rapidly waning
daylight is insufficient for further observation. No doubt
the column will disappear down some hole at the base of a
tree or stone.
Such is a raid of the Ponera Ant in an organised body,
which, for cohesion, mobility, elasticity, and unity of action,
could not be excelled by any human gathering, and cannot
be accounted for by the mere word instinct — a word so
easy to jerk off the end of a pen, and yet so difficult, even
impossible, to define with the combined aids of human speech
and reasoning.
Wherefore, this effort to picture in words what the greatest
masters of the brush could but portray in sombre colours,
which would appear very flat without detailed action. A
series of still photographs would serve the purpose no better.
A series of cinematograph pictures would be nearer the mark,
but surely a streak of small objects moving for half an hour
at a uniform pace, and this to end in a three-minute struggle,
would make a poor picture. No, there are some actions and
efforts of which descriptions had better be left to words,
however faltering and inadequate such words may be.
THE MIGRATIONS OF BUTTERFLIES
By H. L. Andeewes
The fact that large numbers of butterflies have the habit
of travelling in a body in a fixed direction at certain times is
well known, and many records of such movements are to be
found in various scientific publications. Several species,
THE MIGRATIONS OF BUTTERFLIES
73
belonging to several families, are recorded as having this
habit, e.g., many Pieridse, Euploea among the Danaidse, Pyrameis
cardui among the Nymphalidse, Polyommatus bceticus among
the Lycsenidae, and Calpodes ethlius among the Hesperiidae.
Beyond the bare fact that such migrations do take place but
little seems to be known. It is always assumed that the
necessity for ensuring an ample food- supply for the succeeding
generation causes these movements, and in the absence of
any evidence to the contrary this must be accepted as the true
reason. The depletion of the food- supply following on an
abnormal increase of the numbers of the caterpillars in a
district, or an insufficiency of food due to drought or any
other unfavourable condition, is ample cause for an exodus
from the district. This is as obvious in the case of butterflies
as in the case of mammals or birds ; but there is a fundamental
difference between the cases. Butterflies have a life of only
a few weeks (if we except the few that hibernate in temperate
climates), whereas the higher animals live for some years.
When, therefore, a migration becomes imperative for the latter,
they are practically certain to have among them individuals
with previous experience to guide them. With butterflies
the migration takes place without any such help. It is this
fact that makes these journeys of hundreds of miles so
wonderful. It is incredible that flocks consisting of myriads
of butterflies should all go in one direction in search of food
on the mere chance of arriving at a suitable spot. We are
compelled to fall back on instinct for an explanation.
Lemmings have this inherited impulse, or instinct, to migrate
at times in a certain direction ; in their case it leads to their
undoing, for they tumble into the Baltic and drown where
their ancestors found dry land. Does some similar fate
overtake the butterflies ? It is to be supposed that on arriving
at their destination they will find, as a rule, the district already
occupied by residents of their own species ; so that unless
the vast majority come to grief, over- population must occur
in the new district and the trouble continues. So another
migration must take place, and so on indefinitely. Until
voluminous and accurate data are collected from all parts
of a country their movements cannot be traced. Although
to do so, especially in a country like East Africa, with its
74
THE MIGRATIONS OF BUTTERFLIES
small white population, is difficult, it is not impossible. Even
supposing their movements to be traced, there remains the
problem of the origin of the habit. It probably began by
small migrations. It is conceivable that in past times their
foodplant existed in a belt, or a wide sheet, which with geological
and climatic changes became broken up gradually into dis-
continuous areas, so that the small migrations became slowly
lengthened out until they reached their present great length.
Evidence is badly needed as to the proportions of the
sexes in the flocks. In one observed by the writer recently,
males and females were in about equal numbers. Canon
Rogers, in a letter to the writer, says : ‘ There is some evidence
that they frequently consist mainly or even exclusively of
cJcJ.’ If the latter statement proves to be correct on further
investigation it will add a complication to the problem.
The following facts were noted by the writer in connection
with two migrations of the Pierine butterfly Belenois gidica ,
passing eight miles N. of Lumbwa Station. The first began
towards the end of January, 1921, lasting until about the
middle of February. The direction was rather W. of N.W.,
so that those passing the point of observation were on a line
which would eventually take them between the N.E. corner
of the Victoria Nyanza and Mount Elgon. This flight was
also seen by the writer about Mola Station, going in exactly
the same direction. The second, an even heavier migration,
was seen first on March 2, travelling about N.N.W., or in
a direction which would clear Mount Elgon on the E. This
continued for about a fortnight. When high hills are reached
there is no deviation ; they pass over the hills without changing
their direction. When blown off their course temporarily
they seem to make up the leeway as soon as opportunity
occurs. They fly as a rule near the ground, but many are
to be seen at a height of fully 100 feet, especially over hill-
tops where they adopt a lazy, floating mode of flight. In a
violent gust of wind those passing over a forest- clad hill- top
dropped and settled on the ground and shrubs in the forest,
until the wind was normal again, when they resumed
their journey at once. The speed varied, according to the
direction and force of the wind, from as low as five or six to
as much as twelve miles an hour, averaging about nine miles
ON BAOBABS AND RUINS
75
an hour. They got under way about 9.80 a.m., and began
to settle down for the night on low herbage towards 5 p.m.,
when it was noticed that a certain amount of pairing occurred.
The flight goes on without cessation, except when the sun is
obscured, when they settle until it is fully out again. The
only other stoppage is for short visits to flowers on the way.
The few left in the district when the migration has passed
by consist largely of very dwarfed examples, some no larger
than a Polyommatus boeticus, presumably weaklings unable to
continue the journey.
The only other records in the writer’s possession are
contained in the above-mentioned letter from Canon Rogers,
dated March 8, 1921, in which he says : ‘We have had two
marked migrations in these parts [Kabeti] a few weeks ago,
i.e ., Catopsilia florella going N. followed by Belenois mesentina
going S.’
Any notes, however seemingly trivial, on this subject will
help towards solving a very interesting problem. In all cases
a fair number of specimens of the butterflies (in paper triangles)
should be sent if possible, accompanied by accurate notes on
dates and duration of flight, direction and locality, with any
observations on habits, attacks by enemies, etc. If an unusual
number of any species, appearing travel- worn, should be
recorded as occurring suddenly in any district without showing
signs of moving on, it would be a fairly certain indication
that that district was the objective of a migration, and the
butterflies should be found laying eggs.
ON BAOBABS AND RUINS
By C. W. Hobley
In travelling along the coast of East Africa from Yanga
to Lamu, groves of baobab trees will be noticed at intervals.
The one known to most visitors is that on the south-west side
of Mombasa Island, other known examples occur on the
north side of Takaungu creek and the north side of Kilifi
creek. Upon investigation, I was somewhat surprised to
discover that these groves were almost invariably found
76
ON BAOBABS AND RUINS
on the site of an old ruined town ; the frequency of this
occurrence seemed to be more than a coincidence, so I cast
about for an explanation. After much fruitless enquiry, an
old man gave me the following explanation, which is so simple
and so probable that I cannot help thinking that it must be
correct.
He stated that if the Swahili woman wishes to cleanse her
hair she obtains a quantity of the seeds of the baobab 1 and
macerates them in water and makes a hair wash.
My informant went on to say that when the women had
made their hair wash they threw the seeds out on to the
domestic dust heap, and while the town was occupied, of
course, if they germinated they had very little chance of
survival, for the goats would nibble off the seedlings, but once
the place was deserted, owing to war or other causes, the bush
would cover the area, and the more recent baobab seeds would
germinate along with other plants.
In this case it may be deduced that the age of the older
baobabs, if it can be determined, would give with reasonable
accuracy the date of the abandonment of the site.
The hard shell which forms the outer covering of the
baobab is also used for drawing water out of wells. A square
hole is cut out of the side near one end, the seeds and dried
pulp are taken out and thrown away, or possibly the latter
is used for hair wash, and three or four of the empty shells
are suspended on a rope and used for raising water.
This is a collateral explanation of the presence of these
baobab groves on old town sites.
There is a current idea that, on account of the great bulk
of the baobab trees, they are of enormous age ; this belief is, I
consider, a somewhat ill-founded inference.
The baobab belongs to the mallows (Malvaceae), and the
wood is hardly worthy of the name, as it has the consistency
of a cabbage stalk, and it is sometimes used for the manufacture
of paper.
I endeavoured to count the rings of growth in a medium-
sized tree which was cut down in constructing a road ; allowing
1 The flesh of the baobab fruit in which the seeds are enveloped, as is well
known, contains a certain amount of tartaric acid, and possibly in the form of
tartrate of potash, and it is sometimes used for making a cooling drink.
SHELL REMAINS
77
for two rings per annum, that is, one for each of the two
rainy seasons in each year, I could not count more than 220
rings. It was not easy to be certain of the number when one
approached the outer circumference, for naturally the rings
gradually became thinner as one counted from the centre to
the circumference. Assuming that the count was fairly
accurate 220 rings would give an age of 110 years, which
seemed small for a tree about ten feet in diameter.
Baobab trees are difficult to cut down owing to the spongy
nature of the wood and their great girth. During the railway
construction it was found that by anchoring one end of a
steel rope, taking a turn round the tree and attaching the
other end to a traction engine, the rope would cut through
the base of the tree. The trouble was, however, not then
finished, for the tree just stood where it was, and the rope
had to be attached to the upper branches and the tree pulled
bodily over. Baobabs are deciduous, they only bear leaves
for a very short period during the year, and the remainder
of the tree stands as a bare dropsical monstrosity, but even
then a grove of them has a charm of its own, and they give
a very distinctive note to the scenery of the East African coast,
and will be missed when they are swept away to make room
for improvements. The great white flowers, some six to eight
inches in diameter, are very beautiful in their way, but like
the leaves they last a very short time ; the young leaves are
greatly prized as food for livestock, and slabs of bark are cut
from the trees by the natives to make rope and plaited bags.
The baobab, nevertheless, appears to have the faculty of
healing wounds in its epidermis, however extensive they may
be. The fruit juice is also used by rubber planters as a
reagent for congealing the latex.
SHELL REMAINS
By C. W. Hobley
In some parts of the coastal plain in British East Africa,
particularly south of Mombasa, one’s attention is attracted
to the fact that the ground is strewn with myriads of fragments
78
ANNUAL REPOET, 1920
of marine shells, and at first sight one might attribute a
natural origin to these accumulations, Le., premising that we
had the relics of a raised sea beach ; further enquiry, however,
elicits the fact that they are all of human origin, and derived
from live marine shells brought up from the seashore and
broken up where there was a convenient exposure of old coral
reef in order to extract the molluscs inhabiting the shells, and
which are an article of diet among the Wa Digo, particularly
when they are a little short of food. Similar shell deposits
are recorded from other countries as left by early man of
Neolithic times.
To the Editor
Dear Sir,— I must confess to carelessness in handing in
my MS. of Notes on Tortoises, in Journal 16, page 50, where
‘ upper shell (plastron) ’ should read ‘ upper shell (carapace) ’.
As an opportunity for proof-reading cannot be afforded, the
error went to press.
Kilossa, June 14, 1921. A. Loveridge.
ANNUAL REPORT, 1920
The period under review has been one during which, for
financial reasons, the Society has had to curtail its activities,
and as a result there is little to report.
Several members of the Committee proceeded home on
leave during the year, and as vacancies could not be filled,
the Society became more or less dormant. The latter part
of the year has been marked by renewed activity, and the
position of the Society, both as regards its undertakings and
financially, shows marked improvement.
Membership — The membership has steadily increased,
indicating continued interest on the part of the public.
Museum*— No records have been kept as to the number
of visitors.
One new forty-drawer cabinet for insects has been installed,
ANNUAL REPOET, 1920
79
and shelving erected in the workroom, to accommodate the
study collection of reptiles.
The entire exhibition collection has been relabelled and
additions made. The large labels for the Game Heads were
printed gratis for the Society by the Leader Office.
Very few fresh specimens have been added, but small
collections which had been sent home for identification have
been returned and incorporated in the general collection.
Curator .— Mr. Loveridge returned to Nairobi in August,
and assumed his duties as Curator at an increased salary
commensurate with the increased cost of living. As the
Society was unable to promise employment at this increased
salary for more than three months, Mr. Loveridge resigned
his appointment in order to join the Game Department in
Tanganyika.
During Mr. Loveridge’s period of office the entire Reptile
collection was rearranged and labelled, and the general exhibits
overhauled. Mr. A. F. Gedye was appointed to the Curatorship
for a period of six months as from November 1 .
Publications — One Journal was issued during the year,
and manuscript for the succeeding number sent to the publishers
in October.
The cost of publishing the Journal continues to increase,
and now stands at about £90. In order to keep the cost
within the means of the Society, all illustrations have had to
be omitted.
Special Funds.— The Illustration Fund has not received
the support it deserves.
A special Curator’s Fund was opened, and certain gentlemen
have generously contributed thereto.
An unsuccessful appeal was made to Government for funds
to meet the cost of the Curator’s salary for one year.
Monthly Meetings — Owing to the disinclination of members
to read papers at the members’ meetings, no meetings have
been held during the year.
Financial — A statement has been prepared by the Hon.
Treasurer and is appended hereto.

The former is said to have been invented by a man of the
tribe as recently as 1834, and Weule considers that it was
suggested by the writing of Europeans and Mohammedans.
A few examples are given in Fig. 5.

primitive attempts at conveying thoughts by marks are

manner, and that in neither case did written language com-
mence with the invention of an alphabet. Further, it seems
certain that ideographic writing cannot survive alongside
languages recorded on an alphabet basis, for ideographs fail,
to a great extent, in the expression of abstract ideas. The
Greek alphabet killed the Egyptian hieroglyphs ; and the
cumbrous Chinese so-called alphabet, which is ideographic, has,
I take it, only survived owing to the long isolation of China.
As regards these poor African attempts, they are, of course,
doomed to early extinction as elementary European educa-
tion spreads among the tribes.
The invention of accepted symbols to express the various
vowel and consonant sounds of which words are composed
was one of the greatest discoveries mankind has made.
Consequent upon this discovery was the expression of
musical tones by conventional signs, which was another
great stride in mental development, and without which
music in its modern sense could not exist.
Much research is still needed in regard to the birth and
early development of written language, and it is to be regretted
that black Africa does not appear to provide evidence of a
more advanced nature than it apparently has up to date.
Even with the well-known established languages there are so
many questions one asks oneself : Why, for instance, are
the languages of the European group written from left to right,
whereas Arabic and Persian are written from right to left ?
And even here there is an inconsistency, for Arab numerals are
written from left to right as ours are. Can it be that they
borrowed their numbers from the West ? Why, again, should
the Chinese write in vertical columns ? More information,
however, undoubtedly remains to be collected, and no oppor-
tunity should be missed by residents among tribes which
may, as yet, be comparatively untouched by European
influences.
SEDIMENTARY ROCKS — KENYA COLONY 27
A SHORT ACCOUNT OF THE SEDIMENTARY ROCKS
FOUND IN THE NORTHERN FRONTIER DISTRICT
—KENYA COLONY
By Y. Glenday, M.A., F.G.S.
The Northern Frontier District proper comprises the
country which lies between the left bank of the Northern
Uaso Nyiro and the Abyssinian Frontier stretching east-
wards from Lake Rudolf through North Jubaland to the Juba
River.
This somewhat remote and turbulent area is of great
interest geologically, containing, as it does, Lake Rudolf (part
of the eastern arm of the Rift Valley), the great Archean
complex of gneisses and schists which form the Abyssinian
28
SEDIMENTARY ROCKS IN THE
escarpment proper, and the volcanic mountain of Marsabit
with its circumambient plains of lava.
Not the least interesting feature, however, is the great
development of sedimentary rocks which have been found
to exist on the eastern portion of the district, and to
stretch south-eastwards towards the sea, disappearing before
reaching the latter under the alluvial plain of South Jubaland.
As one of the first persons to have the opportunity to study
this series, it is my intention to try and give a short account
of their extension and mode of occurrence. As, however,
all my field notes and specimens are at present in England
for the purpose of identification and detailed study, it will
be remembered that this account can only be of a general
descriptive tentative nature.
To an observer standing on Dandu, one of the eastern
points of the Abyssinian escarpment, and looking southwards,
a very striking contrast in scenery is noticeable. To the west
are to be seen the characteristic ‘ monadnockic ’ hills of gneiss
jutting out of the bush-clad plains, whilst to the east a low,
gently undulating scarp is observed, behind which the
country dips gently to the S.E. The latter is approximately
the western outcrop of the sedimentary rocks, and occurs on
the western section of the Gurre country.
The rocks can be easily divided into a limestone and sand-
stone series, both of which are generally flat-bedded or dip
gently to the S.E.
The Sandstones
These are massive and fine-grained, of a deep reddish
colour, showing occasionally striking patterns of bands of
colours varying from black and purple to a light ochre.
This is very noticeable at Dakka Dima (meaning red rocks)
on the W.N.W. of Eil Wak. They suggest an origin from the
decomposition of the ancient gneisses and schists. The sand-
stones stretch as a broad band across the Gurre country
eastwards to the Juba River, thickening to the N.E., but they
do not outcrop northwards on the Daua River until Beila
is reached. Southwards they extend below Serenli and seem
to disappear N.E. of Salugli.

NORTHERN FRONTIER— -KENYA COLONY 29
Although a considerable search has been made, off and
on, during a period of over three years, very few fossils have
been found. A few were found near Jimale on the western
outcrop and are at present being identified. The occurrence
is worthy of note, and their determination is awaited with
interest.
The topography of these rocks is characteristic, as they
form typical table mountains, possessing the characteristic
scarps with flat plateau tops ; sometimes they are gently
inclined and have long dip slopes. These are very noticeable
in the Marehan country. Another interesting feature amongst
the sandstones is the Eil Wak basin, containing gypsiferous
beds. These were first noticed and described by Dr. J.
Parkinson. This area consists of a soft, greyish-white cal-
careous limestone containing numerous spear-shaped crystals
of gypsum varying in size to five or six inches long. This is
overlain in parts — noticeably to the north — by a hard, un-
fossiliferous, white limestone. In spite of numerous searches
no fossils or even traces of them were found.
The basin has a diameter of approximately twenty miles,
and is surrounded by sandstones, with a possible outlet to the
S.E. The area is characteristic of a desiccated salt lake,
and' is probably part of a much larger lake, as suggested by
J. Parkinson (cp. Abs. Proc. Geological Soc., No. 980, 1915).
The area is valuable as it contains over 100 wells which
are tunnelled down to approximately 80-40 feet deep. The
water is highly prized by the Gurre, who own them, owing
to its remarkable saline properties.
These are characteristically developed on the Daua River,
where they consist of hard unfossiliferous limestones inter-
calated with muddy limestones and shales.

This section is of further interest, in that the beds seem
to have undergone gentle flexuring, as many of the fossils found
showed marked signs of crushing.
In bands B and G many fossils were found which are
awaiting identification. The fauna is very suggestive of the
Mediterranean facies in Jurassic times.
Further sections were studied in various places, but those
found on the Juba, particularly at Salugli, are worthy of brief
notice here. The sections are small and contain practically
only muddy limestones and shales. In the latter, remains of
ammonites were found which are of great interest, as they
must be similar to the remains of ammonites found by J.
Parkinson on the other side of the river at Kukatta (cp. Abs.
Geol. Soc., No. 980, 1915).
VARIATION IN EAST AFRICAN BUTTERFLIES 31
Mention must also be made of the profuse numbers of
belemnites to be seen on the caravan track which runs north
of Serenli at Mata Warseisa. They are of a sulcate form.
Conclusion
On the completion of the identification of the various fossils
found, the exact age of this large development of sedimentary
rocks should be determined.
For the moment it is submitted that the narrow coastal
strip of sediments broadens out and extends to at least 40J°
long. E. These run northward across the Daua River, pro-
bably without interruption, through Italian Somaliland to
British Somaliland. The writer visited the latter place about
a year and a half ago and was much struck by the similarity
in lithological features of the Bihendula and Daua limestones.
There was also a marked similarity in the sulcate ammonites
found.
Economically these rocks might prove of value as a source
of oil, but this would seem to depend largely on the results
of the investigations recently carried out at the Daga Shabell
oilfield in British Somaliland. It is noteworthy that the
Shabell sandstones have been identified as Jurassic age.
GEOGRAPHICAL VARIATION IN EAST AFRICAN
BUTTERFLIES. PART II
By K. St. A. Rogers, F.E.S.
NYMPHALIDiE
Most species of Precis are more interesting for seasonal
than for geographical variation. It is true that the African
forms of P. orithyia and P. hierta differ to some extent from
the Oriental species, and form races of those species which
are generally smaller and darker, but that is only to be ex-
pected. There is, however, one species, P. elgiva in East Africa,
which is a form of the western P. terea which has some
32
GEOGRAPHICAL VARIATION
interest. The former has a narrower, central fulvous band
across both wings than the latter, whereas, in most cases,
the western forms differ from the eastern- forms in their more
extended dark markings. P. terea reaches as far as Londiani,
but in Nairobi P. elgiva is found, and shows no tendency to
approach the type form. It seems, therefore, that this is another
case in which the Rift Valley forms the boundary between the
two races.
Hyipolimnas ( Euralia ) dubius is particularly interesting from
the point of view of geographical variation. The western form
exists under two forms, H. dubius, with black, white-spotted
fore- wings, which mimics Amauris, such as A. jpsyttalea, and
H. anthedon, with large, white patches on the fore-wings, which
mimics A. navius. These have been proved by breeding to
belong to one species, though the models are perfectly distinct.
In East Africa, also, the species exists under two forms similar
to the two western forms, namely H. mima, corresponding to
H. dubius, and H. wahlbergi, corresponding to H. anthedon.
The latter has very much larger, white patches in both wings
than H. anthedon, precisely as A. dominicanus, the eastern
subspecies of A. niavius, has larger patches than its western
representative. However, A. jpsyttalea only extends into the
Nyanza province of Kenya, and in the rest of the country
there are two jother species of Amauris, i.e. A. echeria and
A. albimaculata, which resemble each other so closely that
they can only be separated on close examination, and
both extend to the western parts of Uganda. In both
these species the white spots on the fore-wing are much
smaller than in A. jpsyttalea and its allies, and it is a
remarkable fact that H. dubius mima also has the spots
on the fore- wing much smaller than in H. dubius ; so that
the two forms of the same species on coming into East
Africa vary in exactly the opposite direction, one by an
increase in the white markings and the other by a decrease.
In the region around Victoria Nyanza all forms seem to be
found and no doubt intermediates occur; but in the forests
near Nairobi the eastern forms alone are found, though
they are not common, and they also occur together in
the Ukamba and Teita countries, but in the coast district,
IN EAST AFRICAN BUTTERFLIES
33
during many years collecting. I never met with the mima
form, though the wahlbergi form was much commoner than
elsewhere in the colony ; and it is significant that the model
of this form, A. albimaculata, is also absent from this district,
and that as soon as it is found, i.e. in the Teita district,
H. mima also appears. I do not think that it will be of
importance to go into the small differences which exist be-
tween the races of several other butterflies of this group, as
they require careful comparison in order to be appreciated.
However, the genus Pseudacrcea contains species in which
the difference is marked. Ps. boisduvalli is a red and black
species which is a well-known mimic of the western Acrcea
egina . The eastern form Ps. trimeni does not, however,
resemble A. areca, the eastern form of A. egina, so closely
as it resembles A. acara, the eastern form of A. zetes ; in both
species the eastern forms are characterised by the greatly
extended red markings, but in A. acara there is a conspicuous
subapical orange bar, not present in A. areca, which is gener-
ally found in Ps. trimeni. At the same time it should be
remarked that the latter is very variable in East Africa,
and some specimens approach the western form somewhat
closely. The eastern form extends only as far as Nairobi,
and is often less rare than the western form.
Charaxes pollux. — The eastern form gemimus differs
from the type form in the presence of yellow submarginal
lunules on the hind wing. It is to be found on the Taita
hills and on Kilimanjaro, whereas the type form persists
unchanged from the west coast as far as Nairobi.
Charaxes protoclea occurs as far east as Kavirondo, and is
replaced in the coast district of Kenya by Ch. azota, which
has a wider marginal border of orange in the male, and a
much broader white central band in the female.
The western Libythea laius also reaches Nairobi, but
is replaced on the coast by the very similar L. labdaca.
Lycjenid^ and Pierin.®
Many of the Lycsenidse run very close together, and seldom
exhibit much geographical variation as regards western and
84 VARIATION IN EAST AFRICAN BUTTERFLIES
eastern forms. However, Telijpna carnuta, which is found
as far east as Uganda, is replaced in the coast district by
T . rogersi, with more extensive orange-brown markings, and
Myrina silenus, which reaches Kavirondo, is replaced at
Nairobi by N. ficedula, which is a common species as far as
the east coast and also South Africa.
The Pierinae are more remarkable for local and seasonal
variation than for geographical races, and there is also a
great deal of individual difference, so that with our present
knowledge it is not easy to recognise geographical variation
in most cases. Perhaps the clearest case is that of Mylothris
narcissus of the Taita hills, which is replaced at Nairobi by
M. jacksoni.
Papilionid^e
Pajpilio rex of Nairobi is replaced in Uganda by the form
mimeticus, which is darker, and on the west by the form
schultzei, which is quite without the red mark at the base
of the fore-wing. In Kavirondo there occur intermediates.
P. dardanus is very interesting from the point of view
of geographical variation as it is for its mimetic forms.
There are forms with non-mimetic females in Madagascar
and Abyssinia. Besides these the races recognised are
cenea from South Africa, tibullus from the east coast (hardly
separable from cenea), polytrojphos from the escarpment in
Kikuyu, and dardanus from Uganda westward. At Nairobi
the form is tibullus, probably influenced by intermixture with
polytrojphos. The western males have only two or three
large submarginal black spots on the hind wing, but those
from the coast of Kenya have a very wide black sub-
marginal band, which is much less pronounced at Nairobi,
though it is very variable. On the other hand the Hijppocoon
females have the outer half of the hind wing black on the
west coast, but on the east coast the black band is very
greatly reduced, following the model Amauris niavius.
This is one of the clearest cases known, as it is most
improbable that climatic conditions should result in less black
in one sex and more black in the other sex of the same species.
It will be noted that in the large majority of the species
DEATH’S-HEAD MOTH IN BEEHIVE
85
mentioned there is a progressive diminution of the black
or fuscous markings from the west to the east, but there
is much difference in the distance penetrated by the western
forms, some stopping at the lake and others reaching Nairobi.
DEATH’S-HEAD MOTH IN BEEHIVE
(To the Editor)
The following notes may be of interest to members. A
swarm of bees have taken up their abode in my house, which
is a wood and iron building. The bees have got in between
the wooden wall of the dining-room and the outside iron.
Exactly opposite the nest is a sofa, where I usually sit and
read in the evenings. From my seat I can distinctly hear all
that is going on in the bees’ nest ; the bees keep up a buzzing
sound, which ranges from a high-pitched squeak to a booming
roar. One night a most unusual noise started up under the
eaves and proceeded to the nest. At first I was unable to
guess what it was — it sounded like a bat or large moth flutter-
ing about. This noise started every night at 7.80 p.m. and
had been going on for a week. I put a strong light outside,
shining on to the wall, and waited till the visitor came out,
which I found it did in a place where I might, with luck, catch
it. After a short wait I could hear it coming ; then, as it came
out, a lucky sweep with the butterfly net got him ; it was a
cJ death’s-head hawk moth. Shortly after the $ came out
and I got her too. Both specimens were nearly perfect, in
spite of the knocking about they had received in struggling
up and down in the narrow- partition in the wall. On opening
their bodies I found they contained about a teaspoonful of
honey each. I showed these moths to a native bee fundi,
who said at once that he knew it, and that it fed on bees.
His idea was that it ‘ caught the bees and ate them,’ and he
explained ‘ that the moth eats half the bees in the hive, then
the other half fly away and leave the hive.’
One thing seemed very curious, and that was that the
bees appeared to be frightened and made no noise while the
moths were feeding on the honey. — K. E. Dent.

PODOCARPUS TREES NEAR NAIROBI
NOTE ON THE OCCURRENCE OF PODOCARPUS
TREES NEAR NAIROBI
By H. M. Gardner
Just outside Nairobi, on Thompson’s estate near the junc-
tion of the Ngong and Dagoreti roads, is a very interesting
group of trees which probably few people have noticed, and
of which still fewer have realised the significance. There are
only about twenty-five of these trees scattered over an area
of about fifty acres, in the angle between the Kirianugu stream
and the Dagoreti road. In addition there is one solitary tree
and a few seedlings on the edge of the Forest Reserve, exactly
at the junction of the roads, and I am told that there is one
other specimen about six miles away, on the Mbagathi River,
some distance above the old camp. The trees are apparently
identical with Podocarpus gracilior, but the remarkable thing
is that there are no other P. gracilior trees within a hundred
miles. The nearest are probably on the northern end of the
Aberdare Range.
These trees are not recent importations : one is probably
at least 150 years old. There is no trace of this species in
the neighbouring forests, either in the Ngong Forest on the
one side, or ^ the French Mission Forest on the other. There-
fore they can scarcely be the remnants of a formerly much
larger area of this species. A perplexing feature is that the
trees, which are of very varying ages, bear large crops of fertile
seed and regenerate themselves in a wonderful manner. I have
seen not less than 15,000 seedlings at one time beneath one
tree alone, but these all get destroyed by natives cultivating
shambas. In view of this great reproductive power, why
has the species not become distributed over a much greater
area and spread into the neighbouring forests ? It must
imply that the species has not been established in the locality
for a very long period. Possibly the oldest of the existing
trees is one of the original ones, and all the other trees in the
neighbourhood have descended from it ; but as has been
stated above, this tree appears to be not less than 150 years
ANNUAL REPOET, 1921
87
old, and the question as to where it came from and how it
got there still remains.
Many thousands of seedlings have been raised by the Forest
Department from the seed of these trees, but it is feared that
the original group will disappear, as the land on which they
stand has been sold for residential sites.
The dimensions of the largest tree are 10 \ feet girth at
breast height, and 80 to 90 feet in height, and the altitude of
the locality is about 6000 feet. In other districts P. gracilior
is usually found at considerably higher altitudes.
It has been reported recently that there is a similar Podo-
carpus on the Ithanga Hills and on Donyo Sabuk. If this is
correct, it may be that the Nairobi Podocarpus is not P. gracilior,
but a new, closely-allied species which grows in hotter, drier
localities than the true P. gracilior. But this would not
solve the riddle as to how the isolated group of Podocarpus
came to be growing on the Dagoreti road.
THE EAST AFRICA AND UGANDA NATURAL
HISTORY SOCIETY
Annual Report for Year 1921
The year under review marks a period of transition in
the affairs of the Society, and the closing months of 1921
should be looked upon as the real starting point of its
activities as an Institution worthy to take its place with
other scientific bodies of the world.
It had long been evident that the rented building in
which the Society housed its collections was far too small
to allow of a proper display of exhibits, and that an increase
of accommodation was a necessity. It was a step in the
right direction when, at the last Annual Meeting, permission
was given the Committee to enter into negotiations with
the landlord for an extension of accommodation.
These negotiations, however, proved abortive, and the
Committee, after careful consideration, decided that all funds
available for building purposes should be devoted to the erection
of the first block of a permanent Museum on the Society’s plot.
88
ANNUAL REPORT, 1921
Arrangements were accordingly made with Messrs. Harrtz
and Wood to this end. It was found that the funds avail-
able were not quite sufficient to meet the cost of the build-
ing as specified, and these two gentlemen most generously
offered to advance the difference between the money on hand
and the actual cost of the building at ordinary bank rate.
The building was put in hand in July, and was sufficiently
far advanced by November to allow of a transfer of the
Society’s collections. A considerable saving on the cost of
the building has been effected by the generous donation by
Mr. Hutchinson of all lime and sand needed in the building,
and by the very great reduction in price of timber conceded
to the Society by the Equator Saw Mills.
Exhibits. — The activities commenced at the latter part
of 1920 were indefinitely postponed pending removal into
the new building, and no new work was undertaken. Since
the removal, however, work has progressed, and several
additions have been made to the Small Mammal and Bird
collections, whilst the Insect exhibits have also received
attention.
Curator. — Mr. A. F. Gedye acted as Curator from January
to May, and during his period of office particular attention
was given to the various collections of Insecta, and various
groups which had been submitted to experts at home for
identification were gone over and incorporated in the
cabinets.
During the removal, and for a period of a month, Mr.
R. L. Harger very kindly gave his services, and it is largely
owing to his efforts that the exhibits were safely transferred
and rearranged.
Publications.- — One Journal was published during the
year, of reduced bulk, and without illustrations. It is a
matter for regret that this curtailment has come about,
but it was necessary to keep the cost within the limits
of the funds available. It is hoped that this state will be
rectified in the next number of the Journal. No donations
to the Illustration Fund were received during the year,
and we would take this opportunity of once again bringing
this Fund to the notice of members.
ANNUAL REPORT. 1921
39
It must not be forgotten that the Journal is practi-
cally the only link which country members have with the
Society, and it is incumbent on those more favourably
placed to see to it that the Journal is made as attractive
as possible.
Members’ Meetings. — It is to be regretted that no members
have volunteered to give lectures, and it has been impos-
sible to arrange ordinary meetings accordingly.
General Remarks. — The Society is still without Government
recognition, but we have hopes that this will be rectified
in the near future, especially so in view of the fact that
the Society’s collections are used by members of Government
Departments. The Small Mammal collection has been of
considerable help to the Medical Department in deter-
mining the distribution of certain rodents suspected of
being implicated in the spread of plague ; furthermore,
there is little doubt but that the Museum will become a
teaching centre, and as such should be in receipt of State aid.

EDITORIAL.
As several members have expressed regret that the last number
of the Journal was of such small bulk, it is perhaps advisable to
explain the reason, and outline the recent decision of the Committee
regarding the Society’s publications.
At a meeting of the Committee held in July, it was considered
advisable, that, in order to retain and stimulate interest in the
Society, the Journal should be published more frequently. To attain
this end, it was decided to print the Journal locally, and to issue it
quarterly. As the funds of the Society are insufficient to issue a
bulky number, every three months, it was agreed that each number
should be of reduced bulk, the yearly aggregate to be equal to, or
greater than, the old nine-monthly publication.
Journal No. 19 was the first to be issued under this new
arrangement, and No. 20 is presented herewith.
We would take this opportunity of reminding members that
the hopes of the Committee cannot be successfully attained without
the ready co-operation of all.
Manuscripts on any Natural History subject of local interest are
always welcome.
PAPILO DARDANUS.
The most Interesting Butterfly in the World.
Prof. E. B. Poulton, f.r.s.
(Illustrated.)
Naturalists at Nairobi are fortunate in that they live in a district
which is pre-eminent in the light that is thrown on the past history
and origin of the varied forms of this most remarkable butterfly.
The importance and interest of the Kikuyu and Nairobi examples
will, however, be best understood if introduced bv an account of the
finished product, to which they supply essential preparatory stages.
Of the three plates by which this account is illustrated (1) originally
appeared in the Transactions of the Entomological Society of London
(1908, pi. XXIII.) and is here reproduced by kind permission of the
Council, while (II) and (III) were first published in the Proceedings
of the Second Entomological Congress at Oxford in 1912. “ Trans.”
and “ Proc.” with no further addition, except the year and page,
refer to the publications of the Entomological Society of London.
Nearly every note, or paper, quoted in the following pages can be
consulted in the volumes of “ Hope Reports ” in the possession of
the East Africa and Uganda History Society.
The Discoveries of Poland Trimen.
Henry Walter Bates laid the foundation of the theory of mimicry
in 1862 when his great memoir, with its curiously unrevealing title,
” Contributions to an Insect Eauna of the Amazon Valley,” was
published by the Linnean Society (Trans., Vol. XXIII., p. 495).
A. R. Wallace, in the same Transactions (1866, Vol. XXV., p. 1)
showed that Bates’ interpretation of the complex resemblances
between distantly related butterflies held good in the Oriental Region
no less than in Tropical America. Finally Roland Trimen, in the
same publication (1870, Vol. XXVI., p. 497) applied the theory to
African butterflies and especially to the female forms of PapiJio
dardanus.
At the time when Trimen wrote this memoir the name dardanus
was not recognised, the male butterfly resembling, but not exactly
like the examples shewn on PI. II., Fig. I., or PL III., Fig 3, being
then known as merope , described from West Africa, by Cramer, in
1777.

Papilio dardanus cenea, the S. E. African Sub-species of P. dardanus with the four Danaine
models of its female forms. The proof by breeding that the mimics are one species.
(Near Durban, Natal, 1906, G. F. Leigh.)
Later on it was found that this same male had been described
and figured as dctrdanus in the previous year, by Brown. (III. Zool.,
p. 52, pi. XXII., 1776.) Although no locality is given, the excellent
figure left no doubt that Brown’s dardanus was described from a West
African male, and that the name merope had to be sunk. Trimen
was familiar with the South African form of dardanus and he also
examined every specimen he could find in British collections. The
result was always the same; the long-tailed swallowtail “ merope ”
was always a male and there was no female to put with it.
Trimen similarly examined all the specimens he could find, of a
tailless Papilio described by Stoll as cenea (PL I., figs. 4a, 5a, PI. II.,
figs. 9, 10), a mimic of the Danaines, Amauris albimaculata (Fig. 4
on Pis. I. and II.), and A. echeria (Fig. 5 on Pis. I. and II). The
examination of all the cenea (about 25) then known in collections
revealed nothing but females.
Trimen next studied the fourteen specimens, then known, of the
tailless Papilio hippodoon, described from West Africa by Fabrieius,
and later as westernianni, by Boisduval. The S.E. African form of
this black and white butterfly is represented on PI. I., figs, 1, 2a;
PI. II., figs. 6, 7, and its Danaine model Amauris niavius
dominicanus in Fig. 2 on Pis. I. and II. Here too only females
of hippocoon were found.
He finally passed in review the seven specimens, which were all
he could find, of the tailless Papilio trophonius, described by
Westwood, and suggested as the possible female of cenea — shewn
above to be itself a female. Trophonius is represented on PI. I., fig.
3a; PI. II., fig. 8, and its Danaine model Danaida chrysippus , on Fig.
3 of Pis. I. and II. All seven were females.
In arriving at the conclusion that cenea, hippocoon, and
trophonius were three forms of “ merope ,” modified in mimicry of three
Danaine models — an astonishing suggestion at the time — Trimen was
aided by a consideration of the Madagascar Papilio meriones, Felder,
with a male very like “ merope ” (compare figs. 1 and 3, PI. III.), and a
tailed female (fig. 2) whose pattern resembles the male except for a
pronounced black mark starting at the base of the fore -wing costa
and almost crossing the cell. Concerning this feature he wrote : —
“ In the broad black costal bar of the fore-wings which
distinguishes the female in Madagascar, regarded in relation to the
hind-marginal black border, it is not difficult to recognise the material
upon which natural selection might gradually work, to the ultimate
production of a “ Danaidiform ” butterfly like Hippocoon or even
Cenea.
5
How entirely this prediction is justified will appear in later pages;
and, indeed, it was not without confirmation at the time, confirmation
provided by a fourth form of female, dionysos, of which three
examples in Hewitson ’s collection were known to Trimen. This
female form, well-known but rare on the West Coast, is very variable
in that very feature of the female memories which Trimen recognised
as the foundation of the mimetic pattern; and as Trimen points out,
the three specimens of dionysos exhibited two very different degrees
of transition in this respect between the meriones female and the
mimetic hippocoon.
Trimen’s conclusions were received with incredulity. Thus W.
C. Hewitson wrote: — “ P. merope, of Madagascar, has a female the
exact image of itself ; and it would require a stretch of the
imagination, of which I am incapable, to believe that the P. merope
of the mainland, having no specific difference, indulges in a whole
harem of females, differing as widely from it as any other species in
the genus and he went on to compare merope wtih certain South
American swallowtails of which the sexes had recently been
recognised, reducing four supposed species to two. Of these pairs,
at length united, he said: “ Though much unlike each other, there
is quite sufficient resemblance not to shock one’s notions of
propriety.” A little later Hewitson received from Rogers, his own
collector, then in the Island of Fernando Po, Papilio merope and P.
hippocoon, taken by him in copulation; another illustration of the
saying that “ truth is stranger than fiction.” (E.M.M., Oct., 1874,
p/113.)*
My distinguished predecessor, Prof. J. 0. Westwood, was also
at first incredulous, but became convinced when he received from
Mr. Mansel Weale, the males and some of the female forms bred
from larvae feeding together in his South African garden.
I well remember as an undergraduate nearly fifty years ago,
Prof. Westwood pointing out the extraordinarily interesting comparison
between the Madagascar and the African females of dardanus.
I must not dwell at too great length upon the historical aspect
of the subject, but the continental race of dardanus with male-like
females demands some attention.

The Abyssinian and Somali Race, P. dardanus antinorii, Oberth.
Many years after tlie appearance of Trimen’s original Memoir,
two additional races of dardanus with male-like females wer©
described by M. Charles Oberthur (whose recent death is such a
grievous loss to Entomological science) — antinorii in 1883, and
humbloti , from the Comoro Islands, in 1888. The former is of the
highest interest in relation to the evolutionary history of dardanus on
the mainland of Africa. With two exceptions all the known females
of antinorii are male-like. These two astonishing specimens were
described and figured by Kheil (Iris., III., p. 335, figs. 1 and 2, 1890).
Roth are mimetic but differ from all other mimetic females of
dardanus in the possession of long “ tails ” to the hind wings. The
pattern of one, named ruspinae, much resembles that of the
chrysij) pus-like trophonius or rather trophonissa, of the other,
niavoides , that of the niavius- like hippocoon. Coloured representa-
tions of both are given by Dr. Eltringham in Figs. 4 and 8, PL X of
his “ African Mimetic Butterflies ” (Oxford, 1910). (This plate is
entirely devoted to the forms of dardanus and should be consulted in
connection with the present paper.)
The most probable explanation of the presence of these two
extraordinary specimens, is, I believe, that they are hybrids between
the female antinorii and a wandering male from further south,
carrying the factors for the females trophonissa and hippocoon. (Dr.
van Someren’s recent discovery of a form of dardanus at Marsabit,
S.E. of Lake Rudolph, with kippoc'oon-\ike and c)enea<- like mimetic
females (Proc., 1924, p. xxv.) supports this conclusion, and
suggests that collections from still further north, leading on into
Abyssinia, would be of the greatest interest.) In one outstanding
feature, the great size of the sub-marginal white spots of the hind-
wing, the two specimens are alike, suggesting the probability that
they were the offspring of the same female. Being unable to consult
the paper at the moment, I have been kindly helped by Capt. N. D.
Riley, who informs me that Kheil gives the locality as Korata on
Lake Tana, and quotes Dr. Stecker’s statement that the species was
one of the commonest in the district, “ so little shy that they could
be picked off the flowers with the fingers.” Nevertheless only four
females were obtained — ruspinae , niavoides, and two male-like.
7
I have recently examined the females of antinorii in the British
and Tring Museums, and found to my surprise that in a considerable
proportion of them, the tails are much reduced. In one female out
of seven at Tring this reduction is accompanied by an extension of the
dark mark beyond the cell of the fore-wing, conspicuously into area
2, slightly into 3. Two interpretations suggest themselves. The
reduced tails and prolonged costal bar may be traces of earlier
hybridization with southern races diluted by prolonged interbreeding
with pure antinorii ; or these features may be due to the spontaneous
appearance of variations such as that which led to the original
development of a mimetic pattern. It is in favour of this latter
hypothesis that M. le Cerf has recently described a Madagascar
female in the Hill Museum, Witley, with a similar extension into
area 3 on the undersurface (Bull, Hill Mus., Yol. I., No. 3, p. 379,
PI. I., fig. I.). He also describes on the same page a meriones
female in the Paris Museum, with the right-hand tail reduced to a
rudimentary projection, but as the left is normal I do not think that
much significance can be attached to the specimen. There can be no
doubt that such variations are extremely rare in the Madagascar race
as compared with the Abyssinian. Extensive collections from
various parts of Abyssinia and Somaliland would probably throw
much light on this fascinating problem. Antinorii is evidently
common in the Goolis Mountains, to the south of Berbera, a locality
from which my friend Sir Horace Byatt sent me a fine series of
males, but unfortunately no females. The comparison of these
Somali females, if they could be collected, with those from Abyssinia
would probably be highly instructive.
Planemoides, the Mimetic Female form with an Acraeine Model.
All the mimetic females hitherto mentioned resemble Danaine
models, but a most interesting addition was made in 1903, when Dr.
S. A. Neave recognised (Proe., 1903, p. xli.) in a collection made
by Major Wiggins, C.M.G., at the N.E. corner of the Lake Victoria
Nyanza, a female form mimicking the Acraeine butterfly Planema
poggei (also a little further west, the male of PL macarista*). This
new form was named planemoides by Trimen in the same year (Proc.
1903, xxxviii-xl.), and was figured by Dr. Neave in Trans., 1906,
PL X., fig. 8.
Planemoides and its model extend S.W. to Angola, and an Oxford
specimen of the mimic bearing the label “Angola, Rogers: 1873“ was
probably received by Prof. Westwood from his friend Hewitson, to
become thirty years later one of the types of Trimen’s description.
The other type, from the Kavirondo-Nandi district, has also been
kindly presented to the Hope Collection by Mr. C. W. Hobley,
C.M.G.

The non-mimetic ancestor of Papilio dardanus (merope) from Madagascar, and transi-
tional forms, shewing the origin of mimetic females, from the Kikuyu Escarpment,
near Nairobi, British East Africa (6,500 — 9,000 ft.).
Indisputable proof of the soundness of Neave’s and Trimen's
inference that planemoides is one of the female forms of dardanus
was obtained later on by breeding experiments, but before speaking
of these and many others by which Trimen’s original conclusions have
been confirmed, it is necessary to describe briefly the distribution of
the races of dardanus on the mainland.
The African geographical races or sub-species of P. dardanus.
Five races in addition to antinorii are recognised by Dr. Karl
Jordan (Zeitsch f, Wissenschaft, Zool. Bd. lxxxiii.). The dis-
tinguishing characters relied on are the black markings of the male
hind- wing and the form of the male genital armature. Dr. Jordan
concludes that these differences of form are not such as to prevent
interbreeding along the line where the area of one race meets that of
another, and there is strong evidence that such interbreeding takes
place.
The following are the races distinguished by Dr. Jordan, to each
of which I have added the commonest and best-known female
forms : —
1. Papilio dardanus cenea, Stoll. S. Africa, northwards to
Delagoa Bay, completely transitional into the next subspecies, both
geographically and in racial characters. The male and chief forms
of female are represented, with the models of the latter oni Pis. I.
and II. The hippo coon female of this and the next subspecies,
differing from the West Coast form described by Fabricius, has been
named hippo coonoides by Haase, the chief distinction being the
larger white area on the hind-wing, in mimicry of the eastern race of
Amauris niavius, which also has a larger patch than the western race
and has been called dominicanus by Trimen,
2. Papilio dardanus tihullus, Kirby. Delagoa Bay northward
to the Mombasa district. Westward it is completely transitional
into polytrophus in the Nairobi area, and northwards probably into
dardanus, the fused races spreading to the Abyssinian border and
perhaps interbreeding with antinorii. Typically tihullus has by far
the most heavily marked male of any subspecies. The female forms
are very similar to those of cenea.
3. Papilio dardanus polytrophus, Jordan. Aurivillius defines
the area of this race as the high-lying districts of the interior of
Tanganyika Territory and Kenya Colony at the South and East sides
of Victoria Nyanza, extending as far north as Kavirondo. The great
majority of the known specimens are from the Kikuyu Escarpment
and Nairobi. Typically it is a small high mountain form with a male
having the pattern of the subspecies to the west of it, but the
armature of tihullus, to the east. Such a male from the Kikuyu
Escarpment (6,500-9,000 feet) is represented on PJ. III., fig. 3, and
some of its female forms from the same locality in figs. 4-9.
9
At Nairobi it is larger and tlie males often far more heavily
marked, due without doubt to interbreeding with tibullus. The
female forms are extraordinarily variable and include wonderful
transitional stages leading from the male-like female to the fully-
formed mimics. They will be considered in detail in a later paper.
4. Transitional. — Dr. Jordan here places the forms from
"Uganda and especially its eastern border, which, in the* structure of
the male armature are transitional between the eastern and western
races, although in other respects — size and pattern — similar to the
latter. Aurivillius in “ Seitz ” does not separate these transitional
forms from dardanus dardanus , the succeeding race.
5. Papilio dardanus dardanus , Brown. — The transitional forms
spoken of under 4 gradually die away as we proceed westward in
Uganda and Tanganyika Territory west of the Victoria Nvanza, being-
replaced by dardanus dardanus, a race which spreads to the West
Coast from Sierra Leone to Angola. These western specimens are
larger than those of the other subspecies, the superiority being
especially marked in the Congo area. Dr. Eltringham has shown
that the pattern of the males from Fernando Po approaches that of
the male meriones of Madagascar on the opposite side of Africa (Proc.
1916, p. xciii.).
The predominant female form of dardanus dardanus, especially
on the West Coast, is hippocoon. The western form of trophonius
has been named trophonissa by Aurivillius, being distinguished from
the eastern form by the greater extent of orange in the fore-wing and
its entrance into the cell. It is everywhere present in the area of
this race, but everywhere relatively rare. Not uncommonly the
orange colour appears in the subapical fore-wing bar, so that all the
markings are orange — the form niobe of Aurivillius. The
corresponding eastern form named salaami, by Suffert, is rarer
relatively to trophonius than niobe to trophonissa, the latter being
probably benefitted by its resemblance to an Acraeine model Planema
tellus. The cenea female is common in Uganda, where its models,
especially Amauris echeria, are abundant, enters the eastern fringe
of the Congo forest, but disappears at some unknown point, before
reaching the coast, although a model is known but apparently not
commonly, on its southern tropical section.
Planemoides is one of the chief female forms of Uganda,
extending with its model to Angola. Dionysos is the interesting
primitive form mentioned as hitherto only known from the West
Coast.

6. Papilo dardanus antinorii , Oberth. — This race has been
already sufficiently dealt with except in one point. The males are
more lightly marked than in any other subspecies, in this respect
approaching most closely to dardanus dardanus and polytrophus .
It is important to remember that each of the races 1 — 5, inter-
breeds with its neighbours in adjoining areas, as is clearly proved by
the intermediate forms abundant along the common boundaries and
often spreading far beyond them. Similarly a female form such as
planemoides characteristic of one race and mimicing models found in
the area of its distribution, may pass, by interbreeding, well into an
area of another, where, far removed from its model but probably
reinforced by fresh invasions, it may persist as a rarity.
It has been already pointed out that antinorii too, probably
interbreeds with the race to the south of Abyssinia, and that the two
extraordinary tailed mimetic-females may perhaps have originated in
this way.
Families bred from known female forms of
DARDANUS IN VARIOUS PARTS OF AFRICA.
It will be convenient to review the breeding experiments which
have been conducted with parents from different races, following the
order already adopted, but deferring polytrophus and omitting
antinorii in which such experiments have never been made.
1. Breeding experiments with the South African P. dardanus
cenea:- —
The first experiments of this kind ever made with dardanus
were those of G. F. Leigh, beginning in the year 1902, when he bred
three hippocoonoides females, twenty-four cenea, and eighteen males
from a cenea female taken “ in cop.” with “ merope ” near Durban
(Trans, 1904, p. 677, PL XXXI.). Later he bred several families
from the same female form, as also from hippocoonoides and
trophonius, nearly always obtaining a majority of cenea among the
offspring and sometimes only this form. In 1923, however, he bred
a majority of hippocoonoides in one family, while Miss Fountaine in
1909 obtained nineteen trophonius , two cenea, and sixteen males from
the eggs of a tropho?vius female taken near Durban (Proc., 1912,
p. cxxxiv.).
One of the most striking of G. F. Leigh’s families, from a
hippocoonoides parent is illustrated on PI. I., showing the female
parent and each female form present in the offspring, together with
its model from the same locality. Of these females three were
hippocoonoides (fig. 2a), three trophonius (fig. 3a), three cenea, with
white spotted fore-wing (fig. 4a), five cenea with the chief fore- wing
spot pale ochreous (fig. 5a). The same specimens are shown
uncoloured on PL II. This interesting family, which included
fourteen males of which one is represented on PL II., fig. 1, is
described and figured in Trans., 1908, p. 434, Pl. XXIII.
11
Many families of the S. African race were bred in 1913 by C. F.
M. Swynnerton at Chirinda in S.E. Rhodesia: Seventeen families from
hippocoonoides parents yielded males and females like the parents;
two from cenea parents, one from trophonius, and one from a form
recently named natalica by M. le Cerf, all yielded males and a
mixture of hippocoonoides with females of the parental form (Proc.
1914, p. lvii.). These results and W. A. Lamborn’s in S. Nigeria
(vide p. 13) strongly suggest a mendalian interpretation, the
common hippocoonoides form being recessive and presumably mating
most frequently with a male carrying factors for the same female
form, the three rarer female parents, heterozygotes, (or hybrids), each
combining its own dominant form with the common recessive
hippocoonoides. Such females mating with the common form of male
carrying factors for hippocoonoides , would give the observed mixture
of female offspring (Proc., 1914, p, lvii-lxx.).
These conclusions were confirmed by Swynnerton’s later
experiments at Chirinda (Proc., 1919, p. xxx.). The fact that cenea
is much the commonest female in Natal and the S. coast of Cape
Colony is explained by the abundance of its models, and the rarity
or entire absence of the black and wThite Amauris niavius
dominicanus. At Chirinda, the black-and-white model is common,
but much less so than the model of the cenea form, and the far
greater effect of the former upon the proportion of the female forms
is probably due to its extreme conspicuousness.
It is to be noted that the locally predominant form may be a
Mendelian recessive, as hippocoon or hippocoonoides in most parts of
Africa, or a dominant, as cenea (over hippocoonoides) in Natal and
Cape Colony.
2. Breeeding experiments with the East African race P.
dardanus tibullus.
A hitherto unrecorded family received from W. A. Lamborn at
Tanga, was reared from eggs laid by a hippocoonoides female, and
contained, as at Chirinda, only females of this form and males. z
3. Breeding experiments with the race P. dardanus polytrophus ,
at Nairobi.
It has already been explained that the extraordinarily interesting
breeding experiments of Dr. van Someren and Canon St.. Aubyn
Rogers at Nairobi will be considered in a future paper. It is,
however, appropriate to point out that the Nairobi race of dardanus
is by no means pure polytrophus, but often contains a strong element
of tibullus, as is proved by the heavy marking present on the. hind-
wing of so many males.
4. Breeding experiments with the transitional race of P.
dardanus in E. Uganda, Etc.
12
Two interesting families bred by Dr. Carpenter were reared from
eggs of females taken in eastern Uganda and just south of it. The
first, in 1912-13, from the eggs of a planemoides female captured on
Bugala Islands in the Sesse Archipelago, Victoria Nyanza, yielded
twelve males, seven hippocoon and three planemoides females, the
latter bred for the first time (Proc., 1913, p. liii.; Trans., 1913, p. 656,
PI. XXXIX.). The second, in 1915, from eggs laid by a remarkable
female combining the patterns of planemoides and trophonissa, taken
near Kakindu Hill, 30 miles west of the Victoria Nyanza, and a little
south of the Uganda border, yielded six males and two females, one
of which was planemoides and the other trophonissa, the western
form of the East Coast trophonius. The female parent thus
produced the two constituents of its pattern (Proc., 1915, p. lxxxvi.,
vide also p. 9 of this paper).
It may be mentioned here that other, although much less
extreme, instance of the fusion of two patterns are well known.
Thus the cenea offspring of trophonius may exhibit traces of their
parentage in the richer, redder tint of the hind- wing patch, and in
modifications of the pattern (Trans., 1906, PI. XVII., figs. 8 and 11,
and description). Similarly, when bred from hippocoonoides, the
oenea offspring may exhibit marked paleness in the same patch
(Trans., 1908, p. 436, vide also PI. I., fig. 4a of this paper). All
specimens with such traces of fusion are probably heterozygotes
exhibiting imperfect dominance, and would split up into their
constituents in the later generations.
5. Breeding experiments ivith the West African race, P.
dardanus dardanus,.
Seven families wTere bred in 1911-13, by W. A. Lamborn in the
Lagos district of S. Nigeria. All the parents were hippocoon, by far
the commonest form on the West Goast, and the female offspring
were of the same form. The seventh family, reared in 1913*
contained besides fifteen males, nine hippocoon and eight dionysos , the
latter an interesting and primitive form, well-known but always rare
on the West Coast, and bred for the first time on this occasion.
The comparison of these, two female forms in the same family
provides strong indirect evidence of the influence of selection. The
pattern of the nine hippocoon, resembling the well-known model,
Amauris niavius niavius, is constant; that of the eight dionysos,
unprovided with a model, extremely variable, ranging from a
specimen like the type figured by Doubleday and Hewitson in which
the oblique bar crossing the fore wing is altogether absent, through
a graduated series to one in which it is well developed.*
* Proc., 1914, p. lxiii. The parent, 17 female offspring and one male, are
represented on PI. 1 of Proc., Linn. Soc., London, 1915-16. The parents of
all female offspring of the first, fourth, and fifth families are shewn on PI.
XI. of Trans., Ento. Soc., 1913, and Proc., 1912, pp. xii. and cxxxi.
18
The Evolution of the Mimetic Females of “ Papilio Dardanus
Further reference to dionysos as a primitive form, in addition to
that already mentioned (pp. 6 & 13), was made by Trimen in 1874
(Trans., p. 148), and nearly a quarter of a century later he drew
attention to a far more significant specimen in the Hope Collection
at Oxford— a female form of tibuUus collected by Lt. Turner at
Zanzibar in 1884. Comparing this with dionysos he describes it as
“ a much closer approximation to the masculine colouration. .
The transverse trace of black in the fore-wing is even fainter . . .
and the colour of the wide Tale' spaces and the hind-marginal spots
in all the wings is almost exactly the pjale creamy-yellowish tint of
the male. . . . There can be no doubt that in this specimen we
have a marked case of reversion to the original colouring of the
female, but it is unaccompanied by any inclination toward the
recovery of the lost tail of the hind- wings.’ 5 (Proc., 1897, pp. lxxxviii.,
lxxxix. ; Trans., 1906, PL XIX., fig. 1.)
Vestiges of hind-wing Tails in some primitive females
and the most ancestral mimetic forms.
In the address from which I have just quoted, Trimen also
expressed the reasonable hope that other transitional females would
be discovered “ at some point in the wide territories between
Abyssinia and Zanzibar ” (p. lxxxviii.). Only three years later the
prediction was abundantly verified by the late W. Doherty, who
made a large collection of female forms of dardanus on the Kikuyu
Escarpment (Sept. -Nov., 1900, at 6,500-9,000 ft.). The great
majority of these specimens are in the Zoological Museum at Tring,
but a good series exists also at Oxford and at the Hill Museum,
Witley. The most primitive of the Oxford specimens, the type of
the female form trimeni , originally figured of the natural size in
Trans., 1906, PI. XVIII., fig. 1., is here represented on a reduced
scale in PI. III., fig. 6. It will be observed that there is a distinct
trace of a “ tail ” to the hind-wing, and it is especially interesting
to note that such rudimentary tails are more commonly found in
hippocoon and hippocoonoides than in any other mimetic form.
In other words the ancestral rudiment is most frequently found
in association with the most ancestral of the mimetic patterns.
That this is the most ancestral and most easily derived from
a male-like pattern such as is borne by the Madagascar female will
be made clear by comparing figs. 2, 6, 7, and 8 on PL III.
14
Two West Coast hippocoon in the British Museum possess
rudimentary tails (Trans., 1906, PI. XIX., figs. 2 and 3) which are
especially prominent in a specimen from Gaboon, and in Lamborn’s
and Swynnerton’s breeding experiments the artificial conditions
appear to have often caused slight but distinct reversion in this
female form. Out of Lamborn’s six families, two included several
hippocoon with these traces j(Trans., 1913, PI. XL., figs. 10, 15, 17,
21). One of the families was artificially cooled in the pupal state,
but it is uncertain whether this condition produced any of the effect.
Still more significant was Lamborn’s seventh family mentioned on
page 13. In this family none of the hippocoon offspring exhibited
traces of a tail which nevertheless were slightly indicated in some
examples of the more primitive form, dionysos. Here too Lamborn
exposed some of the pupae to cold but there was no evidence of any
effect.*
My distinguished friend Prof, van Beinmelen of Groningen has
contended in his interesting papers on the origin of the patterns of
Lepidoptera, that these tail-less mimetic females, of tailed males are
not derived from a form like that of the male, or the tailed female of
Madagascar, etc., but are descended, unchanged in this respect, from
the tail-less ancestor of the tailed Swallowtails. The facts mentioned
in the preceding paragraph are very difficult to reconcile with such a
hypothesis, and. a discovery of Lamborn’s furnishes a complete
refutation. He has recorded that “ the p;upal wing-cases are the
same in shape in both sexes, but whereas, in the male, the tails are
readily visible on either side of the mid line on the night before
emergence, in the female the space for their reception, though
present in an equal degree, is unoccupied by wing-tissue.” (Proc.,
1914, lxvii.).
It will be observed that the vestigial tails often associated with
primitive patterns and colours provide strong evidence against the
conclusion that the two Abyssinian females with long tails and fully-
developed mimetic patterns (p. 7) are ancestral or in any way
represent stages in the evolution of the mimetic females of dardanvs .
t The sex of the future butterfly can be ascertained by an examination of
the wing-cases by the aid of transmitted light, from about the fourth day,
if development is proceeding normally. — {Editor.)
During recent experiments, it was found that in cases where the pupae had
suffered a severe shock just when the larvae had changed to pupae and
were still soft, the resultant butterflies showed distinct traces of male pig-
mention varying from a small patch of yellow, to complete male colouration
of one, two, three or all the wings. Also, that in cases where there was
only slight male pigmentation, tails were present. — {Editor.)
15
The Pale Yellow Pigment of the Male dardanus proved
TO EXIST IN THE PRIMITIVE FORM OF FEMALE.
Dr. E. A. Cockayne has shewn that the yellow colour of the m&l#
dardanus is due to a special pigment wide-spread in both butterflies
and moths and one which can always be recognised by its fluorescence
(Trans., 1924, p. 1). The parts of an insect’s wing containing this
pigment shine with a brilliant faintly bluish light, suggestive of
moonlight, when exposed in a dark room to the dark ultra-violet
light-rays, most conveniently obtained by the use of a mercury lamp.
Such parts stand out in startling contrast against the dark
background of the other pigments of the wing. Although the
chemical constitution of this pigment has not been determined it is
certainly a definite substance; for it can be dissolved out of the wing
by acetic acid and the solution fluoresces like the dry substance.
At Dr. Cockayne’s suggestion and with his kind help, the pale
yellow pigments of the primitive females of dardanus were tested, and
Trimen’s conclusions entirely confirmed. The yellow pigment of the
female fluoresced like that of the male and is evidently the same
chemical substance. When it has been transformed into white as
in hippocoo7i- like females, or darkened into orange-brown as in
trophonius and trophonissa, it is no longer the same substance and
entirely ceases to fluoresce (Proc., 1921, p. xcix.).
In the note referred to above it is recorded that the pale-
spotted cenea from the Kikuyu Escarpment fluoresced, while the very
slightly darker pigment of the same forms from the lower elevation
of Nairobi was non-fluorescent ( vide also Cockanye in Trans., 1924,
pp. 7 and 8). Later researches on the splendid material received
from Dr. van Someren and Canon Rogers, has however shewn that
fluorescent cenea commonly occur at Nairobi and in families bred
from Nairobi parents, but it is still probable that such specimens
occur in larger proportions at the higher elevation. Rogers has
observed that the paler, more male-like, presumably fluorescent
pigments of cenea appear in the pupa later than the somewhat darker
non-fluorescing pigments of the same form, thus supporting the
conclusions suggested by the physical test, that the two substances,
although closely similar to the eye, are essentially different.
Until Dr. Carpenter conducted his experiments and twice bred
planemoides from a known parent (p. 13), the only direct evidence
that it is one of the female forms of dardanus was founded on a
specimen taken in S.E. Uganda (1902) by Capt. T. T. Behrens, R.E.,
16
“ the specimen was on the left side a gynandromorph, portions of
the male markings and scattered patches of scales being, as it were,
let into the female pattern (vide footnote, p. 15). When the
butterfly is placed in the path of the ultra-violet rays, the little
yellow patch, however small, shines out like a star on the dark
background of the non-fluorescent female pattern.” (Trans., S.E.
Union Sci. Socs., 1923, p. 73; also Trans., 1906, p. 297, PI. XVIII.,
fig. 4.)
Further ancestral elements in trimeni and other primitive
FEMALES OF DARDANUS.
The oblique black bar produced by the lengthening of the outer
end of the costal mark in meriones (of PI. III., figs. 2, 6, 7, 8) has
already been mentioned. In the most ancestral trimeni- like form
named dionysoides by Aurivillius, the mark is unlengthened as in the
most primitive, and, as it happens, the type form of dionysos. The
West Coast form may in fact be briefly summed up as follows : A
fore-wing of trimeni pattern, with all its variations but the white
pigment of hippocoon; a hind-wing of trophonissa, but with a paler
tint. The developing parts of the pattern of both trimeni and
dionysos have cloudy edges (dyslegnic) different from the compara-
tively sharp outlines (eulegnic) of hippocoon.
Another ancestral feature of the pattern of trimeni , often
retained by the fully mimetic females, is the trace of the two more
or less complete gaps in the black band which is the most prominent
feature of the male and un-modified female hind-wing. One of them
is opposite to, but a little lower than the root of the tail, and between
gap and tail is the largest pale area outside the black band; similarly
occupying a corresponding position in trimeni and other primitive
females, and often also in the mimetic females, is the largest pair
of pale markings in the black border. Furthermore, the strong
development of the whole series of these pale markings in the
primitive females, e.g., Figs. 7 and 9 of PI. III., is clearly, a much
less reduced remnant of the area outside the black band of the male
than that seen in the mimetic females, e.g., figs. 740 on PL II.
The fact that these markings are paired is due to the internervular
streak passing through the remnant of pale ground-colour in each
space and cutting it into halves, as is most clearly seen on the under
surfaces shewn on the right side of figs. 2a-5a, on PI. I.
Traces of the other gap, nearer to the costa or front edge of the
male hind wing, are clearly seen on the under surfaces referred to
above (vide especially figs. 2a and 4a) and on the upper surface of
the trimeni shown on PI. III., fig. 6.

The evolution of the hippocoon-like female from trimeni.
It is now convenient to discuss the origin of each of the mimetic
forms from the transitional females of the Kikuyu and Nairobi
districts, following in the first place the order of figs. 2a-5a on PI. I.
The evolution of hippocoon will have already become clear from the
previous account and the comparison of figs. 2, 6, 7, 8 on PL III.
It will, I think, be convenient to speak of the transitional forms
leading to it, but retaining the fluorescent yellow of the male, as
protohippocoon, which will therefore include dionysoides, trimeni, and
any other variety retaining the male yellow pigment and bearing a
pattern intermediate between the Madagascar female and the black-
and-white mimetic form.
The evolution of the trophonius-like form lamborni.
The Kikuyu female figured as trophonius on PI. III., fig. 9, is a
trimeni with the chief pale yellow area, continuous from fore to hind-
wing, almost completely over-spread with an orange flush. The
specimen figured is seen to bear a vestigial tail, entire on the left side,
broken on the right. All the pale colour is fluorescent. This form,
which is well known in the Nairobi district and also occurs rarely in
Tanganyika Territory, as far south as Kilosa (Proc., 1922, p. xlii.)
has been named lamborni (Trans., 1917, p. 335). It bears the same
relation to trophonius and trophonissa that trimeni bears to
hippocoon and hippocoonoides ; and it, and any of its varieties, which
may be described as protohippocoon with the orange flush over most
of the chief pale area, may be conveniently named prototrophonius.
The evolution of the cenea female form.
The history of this form of mimetic female is more difficult to
understand than that of trophonius or hippocoon, but figs. 6, 4, and
5 on PI. III., studied and compared in this order, suggest the line
of development. The hind-wing pattern is derived from that of
trimeni (fig. 6) by a broadening of the black border, the pale yellow
pattern at first remaining fluorescent (fig. 4), but losing this property
property as it becomes ochreous in the hind-wring and ochreous or
white (in the form acene, Sufi) in the fore-wing (fig. 5). The spots
near the margin also become smaller in the final product (PL II.,
figs. 9 and 10). The position of the spots in the fore- wing can be
seen fore-shadowed in the trimeni on PL III., fig. 6. The lower
border of the chief oval spot becomes defined by a band-like growth
of the black ground-colour from base to anal or lower angle of the
wing, while the five spots next in size are completed by the ground-
18
colour invading the pale area along the edges of which they are more or
less clearly recognisable in fig 6. We thus arrive at such a primitive
form of the cenea pattern as is represented on PI. III., fig. 4, and
from this pass by a change in the pale pigment to forms like Fig. 5.
Forms of cenea which still retain, in any part of the pattern, the
fluorescent yellow, may be conveniently called protocenea. At
present these have only been proved to exist in the Kikuyu and
Nairobi districts.
The possibility must not be lost sight of that such an example
as trimeni as is shewn in fig. 6 may be a heterozygote, combining-
pure trimeni and some form of cenea or protocenea , and that the
apparently foreshadowed fore-wing spots may not be truly ancestral.
Such a view can only be confirmed or refuted by breeding
experiments; but it is difficult to imagine how the patterns of figs.
4 and 5 could have arisen from one like fig. 2 except through a stage
similar to that represented in fig. 6.
The evolution of the planemoides female form.
When I formerly discussed the development of this interesting
form (Trans., 1906, pp. 293-7, PL XX., figs. 1-4) transitional
varieties between it and cenea and between it and hippocoon, both
from the N.E. of the Victoria Nyanza, were described and figured,
also unfigured, a form combining the patterns of planemoides and
trophonius (actually trophonissa), from Entebbe. It was argued
that all these intermediates were probably “ the result of first crosses
between females of one form and males bearing the tendencies of the
other female forms. We are compelled to believe that in later
generations their female offspring would not remain intermediate, but
would split up, in accordance with the Mendelian conception, into
the parent forms; and we can thus understand the comparative
rarity of intermediates.” ( ibid, pp. 295-6.)
The last mentioned intermediate, studied in 1906 from a
beautiful drawing by Dr. Eltringham, was presented by him to the
Hope Department and could thus be compared with two other
examples taken by Dr. Carpenter at Kakindu, S. of the Uganda
border. Erom one of these he bred, in 1915, the two female forms,
planemoides and trophonissa (p. 12), thus confirming the conclusions
arrived at nine years earlier.
It is in every way probable that the second intermediate,
between planemoides and hippocoon, is also a heterozygote which
would split up into its constituents in later generations ; but as regards
the first intermediate between planemoides and cenea, now known as
leighi, further knowledge has proved that the conclusion was
mistaken, that the form is stable over a vast area, extending
19
immensely beyond the range of planemoides , so that it is impossible
to adopt the plausible interpretation of leighi as a hybrid between
cenea and a male bearing the planemoides tendency, or vice versa.
We are therefore driven to the hypothesis that the leighi form is a
persistent definite stage in the evolution of planemoides (Proc., 1911,
p. xli).
The leighi form which, as already explained, was first obtained
from the N.E. corner of the Victoria Nyanza, and figured in Trans.,
1906, PI. XX., fig. 1, was four years later bred and captured in Natal.
Eight specimens were obtained, most of them by G. E. Leigh, in
1910, and the form, although always proportionately extremely rare,
has continued to appear (Proc., 1911, p. xxxiii.; 1912, p,. cxxxv, 1918,
p. vii).*
During the past year, 1923, Leigh has both seen it in the wild
state and bred it. Nearly all the leighi forms have appeared always
mixed with other Natal forms, in the families from eggs laid by
trophonins females.
There can be little doubt that leighi arose from the cenea form
probably with the addition of the pale, subapical, fore-wing bar of
hippocoon or trophonius, or more probably retained from the
ancestral trimeni. The other parts of the fore- wing pattern are
nearly as in cenea, the chief difference being a shortening of the
principal mark in area 2, and its growth downwards and outwards
into areas la and sometimes also lb. A tendency towards this
growth is often to be seen in protocenea and denea (e.g., PI. IIT.,
figs. 4 and 5; PI. IT., fig. 9) although very faintly in the last figure.
The colour of all these fore-wing markings is the rich orange-
brown of planemoides, and all that is required to produce the fore-
wing of this latter form is the fusion of the oblique bar and all the
spots except the sub-marginal into a single broad irregularly outlined
bar. The apical spot, common to cenea and, leighi, generally
disappears while the other sub-marginal elements persist. A
specimen of planemoides taken by a native collecter in August, 1910,
between Jilore and Malindi near the coast of Kenya Colony, supports
'* The 1912 family containing leighi, and recorded on p. cxxxvi., is there
spoken of as the second, but, as this form was bred three times in 1910, it
must have been the fourth. A figure of the South African form of leighi
given by M. le.Cerf on PI. II.. fig. 12 of his paper in Bull, Hill Mus.,
Vol. I., No. 3, p. 369. The author is mistaken in thinking that only three
examples of the form are known. He agrees that the southern leighi
corresponds to a stage in the evolution of 'planemoides in other parts of
Africa (see p. ).
20
the above interpretation. In this butterfly, presented to the Oxford
University collection by Canon Rogers, the fore-wing bar is divided
and thus approaches the pattern of leighi (Proc., 1911, p. xlii.). In
the prolongation of orange along the inner margins of this specimen and
the large size of the white patch of the hind wing, we probably witness
the influence of the male parent carrying the factors of hippocoonoides,
by far the commonest form of the female in this district (Trans.,
1908, p. 499).
The hind wings of cenea, leighi, and planemoides have the same
pattern, but the pale ochreous basal patch of the first becomes,
sometimes darker, sometimes much paler, in fact nearly white, in the
second, while in planemoides a pure white patch in mimicry of the
Plariema- models is typical, and a darker one quite exceptional.
Following the lines already adopted, the leighi form and its
varieties may be spoken of as protoplanemoides .
A SIMPLIFIED NOMENCLATURE FOR THE NoN-SySTEMATIC NATURALIST.
The origin and meaning of the forms of dardanus must certainly
appeal to every naturalist who is interested in the problems of
evolution; but the study is hindered at the outset by a complicated
nomenclature, complicated indeed may be inferred from the fact that
only a small part of its intricacy is here revealed. Thus many of the
kaleidoscopic changes undergone by the pattern of the extremely
variable female form cenea have received names and even the same
form, when it appears in a different race, has been given a different
name.
I have suggested in the preceding pages a simple and uniform
modification of well-known names to indicate the primitive form
from which each mimetic female arose ; and, although from the strict
systematises point of view this procedure means further
complication by the addition of synonymns, it is hoped and believed
that the naturalist will be aided in his study of the subject.
In a somewhat similar manner, the various female forms in each
race may be indicated by adding to each the initial letter of the race
name. For this purppse race (4), founded on transitional characters
in the male, may be disregarded, and the initial letters of the
following employed- — cenea, tibullus, polytrophus, and dardanus .
The system of nomenclature, as applied to the principal form names,
but capable of extension to others' is as follows: Proceeding from the
most primitive to the most specialised patterns :
21
A. Mimics of the Danaine, Amauris mavius : (1) c, t, and p,
hippocoon ( hippocoonoides), mimicking A. n. dominicanus; (2)
d. hippocoon, mimicking A. n. mavius. Derived from a male-
like female thought, and p. protohippo coon ( = dionysoides and
tnmeni).
B. Mimics of the Danaine, D. chrysippus: (1) c., and t.
trophomus; (2) d. trophonius ( = trophonissa ). Derived from
protohippocoon through t. and p. prototrophonius ( = lambomi ).
C. Mimics of the Danaines, Amauris albimaculata and A. echeria :
(1) c., t., p., and d. aciene, mimicking the above Danaines
with white spots in fore wing, completely transitional into (2)
c., t., p., and d. cenea, mimicking the pale-ochreous-spotted
form of echeria. Derived from protohippocoon through (p.)
protocenea.
D. Mimic of the Acraeines, Planema poggei and P. macarista:
t., p., and d. planemoides. Derived from cenea or acene
through c., p., and d. protoplanemoides (\—leighi).
I have • attempted in the preceding pages to give a condensed
account of the chief forms of this most interesting butterfly and to
trace the evolution of its mimetic females. In a future paper I hope
to discuss the bearing upon this hypothetical history of the splendid
series of families bred from known female parents at Nairobi by Dr.
van Someren.
NOTES ON THE OCCURRENCE OF A SPECIES OF
CHALICOTHERE IN UGANDA.
By the late C. W. Andrews, D.Sc., F.R.S. (British Museum).
In the number of Nature which appeared on November 10th,
1923, I published a short article entitled “ An African Chalicothere,”
giving an account of the discovery in the neighbourhood of Albert
Nyanza of the characterstiic toe-bone of one of these curious animals.
The specimen was sent to the British Museum (Natural History) by
Mr. E. J. Way land, Director of the Geological Survey of Uganda and
was accompanied by numerous fragmentary remains of Hippopotamus,
Phacochoerus, Crocodile, Chelomans and Siluroid fish together with
some fresh-water shells. The beds from which these specimens were
collected are probably of Pleistocene age.
The Chalicotheres (Ancylopoda) are one of the most peculiar
groups of Mammals : they actually belong to the Perissodactyla, the
uneven- toed Ungulates, of which the horse, rhinoceros, and tapir are
m.

modern representatives, but instead of having hoofs they have
developed enormous claws, the supporting bones of which are deeply
cleft as in some of the Edentata. Indeed Cuvier regarded these
claws as belonging to a giant Manis (Pangolin gigantesque), and it
was not till 1888 that Filhol described a skeleton of a Chalicothere,
called Macrotherium magnum from the French Miocene that it was
shown that the teeth and skulls, which had long been supposed to
belong to quite different animals, were actually parts of a peculiar
clawed ungulate. Abel has recently published an elaborate account
of the Chalicotheres and has given a restoration of Macrotherium
which is here reproduced. The earliest known representative of the
group called Eomoropus is found in the Middle Eocene beds of North
America. In the Miocene various genera occur in France, Samos,
and Pikermi, while in India and China remains are found probably as
late as the Pleistocene.. The extension of the range of the group into
Africa, now recorded is particularly interesting. It will be
remembered that in Samos Chalic other ium is found associated with
Samotherium an animal closely similar to the Okapi, the discovery of
which in recent years created such great interest. Since a
Chalicothere is now known to have existed in this region there seems
to be just a possibility that it also may have survived till the present
day and may form the basis of the numerous stories of strang animals
that have from time to time been published.
Mr. C. W. Hobley in a paper entitled “ On some Unidentified
Beasts ” in this journal (vol. III., 1913, p. 48) gives a summary of
some of the more notable of these stories of unknown animals.
Perhaps the most striking of these occurences are those recorded by
Mr. G. Williams in a note “ An Unknown Animal on the Uasin
Gishu ” (op. ,cit;, vol. II., 1911, p. 123) and by Mr. G. W. Hickes
in “ Notes on the Unknown Beast seen on the Magadi It ail way ” (op.
cit., vol.. III., 1913, p. 53). In both cases the animal seen is
described as a heavily built, bear or hyaena-like creature; a description
which would agree in a general way with the restoration of
Macrotherium illustrated.
It is to be hoped that every effort will be made to clear up this
mystery, for if the animals should turn out to be a Chalicothere, the
interest of the discovery would far surpass that of the Okapi. One
or two bones of the toes would be quite sufficient to determine
whether the beast was a Chalicothere or not, but of course it is
desirous to get the whole animal.

NATIVE FOLK-LOBE.
THE LEPBACAUNS TO KWA NGOMBE.
By S. V. Cook.
Fifteen miles east of Embu Station there rises from the Emberre
Plains the lofty hills of Kwa Ngombe, nearly six thousand feet high.
They are inhabited, the Embu natives say, by buffalo and a race of
little red men, who are very jealous of their mountain rights. Old
Salim, the interpreter at Embu, tells with great dramatic effect how
he and some natives once climbed to near the top when suddenly an
icy cold wind blew and they were pelted with showers of small stones
by some unseen adversaries.. Happening to look up in a pause in
their hasty retreat, he assures me that he saw scores of little red
men hurling pebbles and waving defiance from the craggy heights.
To this day even the most intrepid honey hunters will not venture
into the hills.
Of course this notion of fairies or little men is found in the
folklore of most races. Allingham, the Irish poet, wrote a delightful
poem on these people. One verse might have been written about
these very Kwa Ngombe people :
Up the airy mountain,
Down the rushy glen,
We dare not go a-hunting
For fear of little men.
I hope that no intrepid reader of this journal will be tempted to
explore Kwa Ngombe after reading this, for were he captured, a
punitive expedition against the little men would be a most parlous
undertaking!
