The Swedish Mount Elgon Expedition, which left Sweden at the end of February 1920 under the leadership of Director S. A. Loven, Stockholm, as the name itself implies, had as its chief field of activity in B. E. A. (Kenia Colony) the exploration of the giant old volcano, Mount Elgon, on the boundary between Uganda and Kenia Colony. The leader of the expedition, who was keenly interested in entomology, had undertaken the collection of insects, and the writer — the only zoologist in the expedition — was responsible for the other zoological work. Still I was greatly assisted by Mr. Loven in the collection of birds during the first period of the expedition, and Dr. C Lindblom and Mrs. Ingeborg Lindblom have also procured a few items to the collections, but the great majority of specimens was collected and prepared by myself. I wish to express here my gratitude to all those who have in various ways supported and assisted me and contributed so that this work now appears. In the first place I wish to address myself to my esteemed tutor Prof. Dr. H. Wallengren, to whom I am most deeply indebted, for it was on his recommen- dation that I was appointed to accompany the expedition. With extraordinary kindness and great interest he has always followed my studies and has constantly given me advice and guidance, which have always proved to be of the best. For all the benefits I have enjoyed at the Zoological Institution of Lund I beg to tender him my respectful and sincere thanks. In the next place I wish to express my thanks to Director S. A. Loven, Stockholm, for having chosen me as the zoological member of the expedition. I also wish to tender my expression of grateful thanks to Professor Dr. Einar Lonnberg, Stockholm, under whose gui- dance I first commenced the study of African birds. I am also gratefully indebted to Prof. 0. Neumann and Geh, Regierungsrat Prof. Dr. Anton Reichenow, Berlin, two of the greatest experts in the African bird-life. During my studies at the Berlin Museum they supported and assisted me in the most devoted and amiable manner, and the instruction 1 - 2 - and advice I have had the pleasure to receive from them, makes it not only an obligation on ray part but also a pleasure to tender them my sincere thanks. Further, my thanks are due to my friend Dr. Erwin Stresemann, chief of ornithological department of the Berlin Museum, for all his amiability and assistance during my stay in Berlin. 1 am also indebted to the erudite and expert scholar in African birds, Mr. H. Grote, Berlin, who has in many ways aided my work.i) But not least do I feel my indebtedness to Dr. V. G. L. van Someren, Nairobi, B. E. A., who has always assisted me with his exceptionally great experience and knowledge of African Avi-fauna, and who saved me so much trouble and hard work by naming on the spot a great number of birds procured by the expedition. Last, but not least, I wish to express my feeling of grati- tude, to all those who furnished me with personal equipment, such as was necessary in the Tropics. Without their generous support this journey would certainly have been impossible for me to undertake: Governor, Count R. D e 1 a G a r d i e , Ph.

From our expedition in Africa 1517 birds are brought home, which belong to 330 different kinds, 10 of which are described for the first time by me, and from what I have found after careful examinations, are good and distinct. Although I am convinced that in the collections from Mount Elgon there are several other new forms I have yet refrained from describing anew such as 1 have not been able to establish fully as differing because of the insufficiency of the series from other parts of Africa. In every such special case I have mentioned this under the birds in — 4 — questiou, and it is thus possible and indeed probable that in- vestigations of the bird-kingdom on the eastern slopes of Mount Elgon will include under another name such birds as I, owing to want of material, have been obliged to place under forms at present known. The main object of ornithology is by no means to describe new species and forms, though this task can be a grateful and pleasant one, but a department which is at least quite as im- portant for the knowledge of the "form circles" and their distri- bution is that concerned in the critical examination of the numerous forms already described. In conjunction herewith one is liable to be lead at times into the difficult and com- plicated question of latitude of variation — if I may call it so — of the various forms, and one can then be in a position to establish how forms, which have been considered good, are only different variations of one and the same form. In order that something like a good result in matters of this kind be attained, it is, however a condition sine qua non that there is an extensive material for comparison at one's disposal — which has so often been emphasised — , and that one is quite familiar with the rich and ample litterature of later years. On this basis it is possible to contribute in a greater or lesser degree to the solution of some of the problems of ornithology and modern systematisation: form circles and their extent, the affinity of the various groups of birds, etc. even if this should sometimes happen in a manner which demands the abandonment and rejection of previously approved forms or the description of new ones. This task on account of our uncertain knowledge of the conception of species and forms from a genetic point of view, is however very difficult and it therefore often seems as if the labour expended and the result attained, does not stand in reasonable proportion to each other. It does not come within the scope of this work to analyse all the different opinions concerning forms, variations or races, therefore I will only give a few of the latest. J o r d a n s has (Die Vogelfauna Mallorcas, 1914, p. 34) expressed the opinion that the natural species is the total sum of all forms. The latter, sometimes called subspecies, or races, severally form geographical units and now as the forms, belonging to one and the same „form circle" are among themselves more closely related to each other than to those belonging to an allied circle, the circle of forms make a natural genealogical circle. — Stuart Baker (Bull. Brit. Orn. Club, vol. XL, 1920 p. 80) has defined the con- ception of subspecies in the following manner: „A subspecies is a geographical race or variation, differing in some respect from the form first described as a species, yet linked with it by other intermediate forms found in intervening areas. It is essential however, that the variation before it is named shall be proved — 5 — to be stable within a certain definite area", and he considers "that a subspecies becomes a full species when Nature, in the course of evolution, has eliminated the intervening forms." Hartert (Bull. Brit. Orn. Club, vol. XL, 1920, p. 87) objected to make supposed intergradation between two forms the criterion in the subspecies", and he thinks that "there are numerous instances, in which no intergradation could be traced, — in fact, we seldom found it to exist". As subspecies he con- siders forms which agreed in their main characters, while they differed in details (either of colour, markings or dimensions) and represented each other geographically — or that subspecific characters where "differences combined with geographical separa- tion", agreement in structure and general features, of course, being established. B 0 n h 0 t e considers "that a subspecies is a form of species that differs from the same species in another locality owing to its environment, e. g. its geographical position" (Bull. Brit. Orn. Club, vol. XL, 1920, p. 89). He also considers that when two closely allied forms were found breeding in the same locality they must be considered true species (that is, belonging to diffe- rent "form circles".) The German ornithologist Gengler (Die Balkanvogel, 1920, p. 16) sums up his opinion in the following sentence: "There is no'species and no subspecies. There are only "form circles", which are composed of separate, geographical forms. All these geographical forms are equivalent and none can be made superior or subordinate to the other", and in this way the talk of species and subspecies is done away with. In modern Ornithology the various theories of "form- circles", so meritoriously worked out by Tschusi zu Schmidhoffen, Hartert, Kleinschmidt and many other eminent investi- gators, differ however on one or two points. As already pointed out, Hartert considers that "intermediates between two or several forms by no means always exist", and Stresemann (Journ. f. Orn., 1919, p. 296) also expresses the same opinion, pointing out that mountain ranges often form well-defined divi- ding-walls between two closely related forms. Further, connec- ting-links between islandforms and those on the adjacent main- land are almost always missing. But in those cases where such intermediate forms are really found one can be in a doubt as to how these forms are to be named. As S t r e s e m a n n (op. cit.) has pointed out, it is possible to express by means of figures — almost as in chemical formulae — the degree of the position of an intermediate form in relation to the forms between which the connecting line in question is situated. Such a proceeding, however, seems to me to be arbitrary and too subjective on the whole to have any scientific value, and without careful genetic investigations the affinity between the forms cannot, I suppose, be found by means of a more or less superficial morphological examination. Without any doubt it is necessary in such a case first to establish — if possible — once and for all by means of careful studies in heredity whether this or that form is constant. By this I do not mean, whether the form in question always occurs in the type -locality with these or those distinguishing features, but whether the qualities which characterise the form from all others persist under other external conditions. Investigators have, as the reader is aware, also tried to establish by experiment what factors can influence the formation of forms and to what degree this influence takes place. But the results arrived at will generally be, for various reasons, more or less misleading. On this point I share Dahl's opinion (Grund- lagen einer okologischen Tiergeographie, Jena 1921, p. 3) when he says: "Noch unsicherer wird es, wenn man mit Tieren in der Gefangenschaft experimentiert. um die Wirkung der einzelnen okologischen Faktoren, die fur das Vorkommen in der Natur mafsgebend sein konnen, festzustelleu, wenn man z. B., um fest- zustellen, welche Temperaturschwankungen eine Tierart vertragt, diese in der Gefangenschaft verschiedenen Temperaturen aussetzt. Schon die Gefangenschaft an sich iindert namlich die Lebens- bedingungen von Grund aus, so dafs man immer im Unklaren bleibeu wird, wie weit das sich ergebende Resultat auf die ver- anderte Temperatur zuriickzufiihren ist, wie weit das Experiment also fiir das Vorkommen in der Natur Giiltigkeit besitzt." Banner man (Bull. Brit. Orn. Club, vol. 35, 1915, p, 136) quotes a letter from Prof. Punnet, in which this great exponent of Mendelism writes: "This problem of local races and adaptation is one of the nuts left for us to crack — if we can — . The first thing to be settled is whether the variation is genetic or whether it is merely a direct response to a change in the environment and only endures as long as the change in the environment endures." Before this is experimentally established the majority of speculations and conjectures about the affinity and constancy of the forms can scarcely be looked upon as anything else but "beating the air". The question of heredity and variation is not solved by means of morphological comparisons, however accurate they may be. Thus I share Stresemann's opinion (p. 293) that as long as it is impossible to represent in figures the relation of the sub- tile forms to closely allied forms, it is better to employ the old signs: > and < and to use ^ instead of = for a bird which evidently stands between two others. As regards the systematical order I have followed Reiche- now's system in "Vogel Afrikas". Many writers have other — 7 — systems which, for various reasons, are considered to be better. But as we know very little at present about the genealogical relationship between the larger divisions of the bird kingdom and as it is not clear for the present which is the highest — from a phylogcnetic point of view — (compare J o r d a n s : Die Vogelfauna Mallorcas) I have, for practical reasons, followed Reichenow's system. The references and synonymy have been cut down as much as possible. References to the original descriptions of the species have been given so often before that in many cases I have merely referred to Reichenow's "Vogel Africas". It also interested me, as often as this was possible, to find out the names given by the natives to a number of the birds. In doing so I have not been content with information from only one quarter but have, as a rule, consulted the opinions of two or more other persons. My "personal boy", Juraa bin Masudi, who could write and speak English in addition to several negro- dialects, was of great assistance in interpreting and spelling the native-names of the birds. 0 k o t h , the head of the Kavirondo tribe at Kendu, has himself written the kavirondo-names of the birds on a slip of paper, which I checked later on by consulting other members of the tribe. The new birds described in this work are the following: Streptopelia semitorquata elgonensis, Streptopelia fulvopectoralis, Centropus senegalensis incertus^ Ploceus insignis ornatus, Othyphantes reichenowi nigrofemporalis, Ureginthus hengalus loveni, Cisticola tinniens suhrufescens^ Apalis cinerea minor, Apalis melanocephala nigrodorsalis, lurdinus pyrrhopterus elgonensis. Description of the route. In the brief description given in the following pages of the districts in which we stayed for a shorter or longer time either to study or collect specimens, I consider it best, although the chronological order was not the same, to commence down at Mombasa in the tropical coast-land and then continue to the west or northwest, staying in geographical order at the places where we halted. When we arrived in Africa, disembarking at Mombasa on the 30 th March, the rains of the short rain-period had already begun to fall. According to Cranworth (Profit and Sport in British East Africa, 1919, p. 477) the average monthly rainfall _ 8 ~ in Mombasa for a period of ten years is: March 2.96 ins., April 11.88 ins., May 17.08 ins., June 5.32 ins., etc. The same figures are given in "The Red Booli", 1919, p. 132, for a period of six years. The total rainfall amounts to 58.71 ins. per annum. We stayed at Mombasa four days and made some short excursions in the environs of the Gulf of Kilindini but were unable to make any collections as our outfit, with all the taxi- (ierniic parajjhanclia, had not yet arrived, neither could such be procured in Mombasa. On the 25th April we returned, however, to the coast-land and now spent several days collecting birds, and a rather tine collection of 109 si)ecimens was i)rocured. In the interior of the town itself, in the parks and in the trees growing around the Metropol Hotel Xantopkilus bojeri was breeding everywhere. Indeed, this species was one of the very commonest. In the stony surroundings of the cultivated land we frequently saw Vpupa africana, and Corvus albus (=:: scapulatus) appeared in single specimens or small flocks round the refuse heaps, in the market places or in the dwelling quarters of the Suaheii negroes. Milvus migrans parasifus also occurred in fair numbers, even within the town itself and was very numerous on the Kilindini Gulf, where they swarmed in large flocks round the steamers lying at anchor. It kept company with the gulls, and like them, deftly snatched u[) various edible things from the surface of the water. When I crossed the gulf in a rowing-boat they sometimes flew so near that I could strike th.em with the oar and they were not frigthened off when I shot a few specimens, which fell into the water. The bird-life in the vicinity of Kilin- dini Gulf, where we stayed for the most part, was very rich. In the small groves found here, which consisted mainly of cocoanut palms with various smaller trees and bushes here and there Eyphantornis nigriceps bred in exceedingly large colonies, some- times numbering several hundred nests in the same tree. Most of the birds we collected during our excursions in the coast-land were at this time of the year busy pairing and building their nests. Some had already assumed their new dresses, but the majority, however, were in a more or less advanced phase of moulting. A very common bird in these districts was Dicrurus adsi- milis divaricatus, as also was Boicephalus fusicapillus, although rather difficult to get within range. In the same kinds of lo- cality as that frequented by these birds, that is to say, among the palms and large trees, Oriolus auratus and 0. notatus, Bhinopomastus cyanomelas schalowi, Campeihera caillauti call- lauti, Irrisor erythrorhynchus marwitzi and Accipiter tninullus tropicalis etc. occurred, and from the tops of the Mango trees was heard the beautiful song of Farus albiventris. On the outskirts of the forests — towards the sea — where trees and bushes grew solitary and sparse Lyhius melanopterus, Lyhius torquatus - 9 — irroratus, Fogoniulus pusilliis affinis ocuired sparingly. Among the nnost interestinu discoveries from these areas was Tchitrea perspicillata plumheiceps, which was not previously known from East Africa, and the little, pale Ureginthus hengalus loveni that 1 have described from here. Both here and in the shrub on the shores of Kilindini Gulf there were found various Nectariniidae, among which may be mentioned Anthrepies collaris zamhesiana, Chalcomiira senega- lensis inaesfimatu, Chalcomitra amethystinus JcirJci, Cinnyris mariquensis macrorhpnclms, Cyanomitra obscura neglecta etc., and other birds which often showed themselves were: Fyro- melana nigriventris, flying in large swarms from bush to bush and Melittophagus pusillus cyanodidus^ which either singly or in pairs sat perched on the extreme tips of the slender branches. In the brushwood and thickets in the interior of the forests there was also a rich bird-life. Almost everywhere Cen- tropus superciliosus superciliosus was heard uttering its charac- teristic cry, Xantliophilus hojeri was always seen here in the dense confusion of the low bushes, where Sperniestes nigriceps nigriceps and Lagonostida jamesoni tariiensis lived their secluded lives. Bradornis palUdus suhalaris hopped about on the ground, and under the protection of the dense folioge of the branches Halcyon alhiventris erlangeri, Argya rubiginosa hetiglini, and Pycnonotus tricolor micrus^ tried to escape discovery, while Callus striatus mombassicus clinibed about in small flocks, scre- aming among the branches. In the tops of the trees Chalcopelia cJialcospilos chalcospilos and Streptopelia semitorquata semitor- quata cooed in some secluded nook among the leaves and twigs. During our journeyiugs in these districts I was able to ascertain the presence of only one of our Scandinavian winter guests in Africa: Lonius collurio collurio. While the train halted in the grass plains at Kapiti Plains Station at about 5.300 feet, on the journey up from Mombasa to Nairobi, three specimens of Corvus capensis kordofanensis were shot out of a large flock found close to the railway track. At Nairobi — the capital of Kenia Colony — about 5.450 feet above sea-level, we stayed a few weeks and made collections in the Kiambu forests north of the town, at Ngong southwest of Nairobi and in other places situated in the vicinity, resulting in the acquisition of 215 specimens. Tbe climate here is a Highland climate, for the Lowland climate includes the whole country below an altitude of about 4.500 to 4.800 feet. Both of these differ locally according to altitude and topographical conditions. At Nairobi, which is just inside the Highlands, the nights are always cool and blankets are necessary at mid-summer. At higher elevations it may be very cold, but frost is slight and rare. Though situated so close — 10 — to the Equator, the Highlands are some distance south of the termal equator, hence there is a winter period, though slight. There are two lainy seasons, the short rains usually falling bet- ween October and November and the long rains between March and June. In a tropical country the effect of heat is so depen- dent on the presence or absence of moisture, and generally speaking, the fall decreases on the coast from South to North and increases with the elevation and towards the interior, the fall in certain parts of the Highlands amounting to 150 inches per annum. — The coolest months are from June to August (compare Brown, 1919, p. 522). The average monthly rainfall for a period of six (ten) years in Nairobi (according to "The Red Book", 1919) is: March 4.32 ins., April 9.00 ins., May 5.10 ins., June 1.04 ins., and for Oc- tober 2.88 ins., November 5.53 ins., December 3.02 ins. etc. The total rainfall per annum is 36.41 ins. The bird-life here in Nairobi and the surrounding districts having been so closely and carefully studied and so worthily treated by L o u n b e r g (Birds coll. Swed. Zool. Exp. to B. E. A., 1911) and van Some re n (Ibis, 1916) and others, there is no reason for me in this connection to enter into a further description thereof. Among the interesting bird discoveries from these lo- calities I will only mention a few. By a little brook outside Nairobi, Chloropeta natoXensis massaica occurred in numerous variations, and on the fringes of the forests, Melittophagus la- fresnmjei oreobaies was observed a few times on the sparsely wooded slopes at Kiambu. From these districts I have also described Floceus insignis ornatus, Apalis cinerea minor and Apalis melanocephala nigrodorsalis, of northern migratory birds, Muscicapa striata striata and Lanius collurio collurio were shot here. Owing to a mishap we were obliged to stay for a short time at Kikuyu, 15 miles west of Nairobi, 6.700 feet above sea- level, during which time we added to our collections in the small wooded groves situated in the neighbourhood of the rail-road. The surroundings here are cultivated in all directions. During our short stay here we procured Elanus coeruleus coeruleus, which frequented the tall trees in the areas under cultivation, Sireptopdia semitorquata semitorquata, which was very common and busy building its nest. In the brushwood Cossypha caffra iolaema, Turdus deckeni elgonensis, Centropus s. superciliosus, and many others had their habitations. Serinus striolatus affinis, Nectarinia kilimensis and Saxicola iorquata salax were found in great numbers. Here too Chrysococcyx Maasi and Cisticola prinoides occurred, although rather sparingly. The commonest Weaver bird was Hyphantornis nigriceps. Among the gallina- ceous birds shot was I'ternides leucoscepus infuscatus. — 11 — At Lake Naiwasha, at an altitude of 6.290 feet, we stayed some days in order to study the extremely rich bird-life of the lake. The flat, grassy land in this neighbourhood is taken up by many farms and until the commencement of the 20th century, the grass was kept down by immense herds of Grant's Gazelle, now very rarely seen here. The average monthly rainfall for a period of six (ten) year at Naiwasha is: March 3.42 ins., April 6.85 ins., Mai 3.65 ins, June 4.98 ins. and for Oct 2.70 ins., Nov. 3.31 ins., Dec. 2.13 ins. The total rainfall per annum is 37.75 ins. Lake Naiwasha, some 50 miles in circumference, reposes in a setting of mountains. The acacia-plains reach in some places right down to the shores of the lake, which on the eastern side are very flat and the water very shallow. In the grass-country around the shores of the lake, where the acacias grew wide apart, quite a number of new birds were met with. One of the commonest among Accipitres was Buteo augur, which was found, as a rule, where there were small wooded groves. Spreo superbus was very common here too and Oriolus larvatus rolleil together with Lamprocolius chalyhaeus chalyhaeus and Streptopelia capicola tropica flew about everywhere in the acacias. Among the pigeons occurring here may be men- tioned Stigmatopelia senegalensis aequatorialis. Rather common too were Granatina iafdhinog aster montana, Melittophagtis hul- locJcoides and Bicrurus adsimilis divaricatus. A rare bird in these districts — judging from my observations — was Serimts angolensis reichenoivi and even Jtjnx ruficoUis cocensi occurred rather sparingly. One of the commonest birds here — as in other places — was Macronyx croceus. The thickets and bushes, which here and there skirted the swampy shores were frequented by Centropus superciliosus super- ciliosus, Serinus siilphuratus sharpei, Crater opus melanops cla- mosus, Tricholoema diademata massaica, Laniarius aethiopicus major, Fiscus collaris humeralis, Nedarinia Jcilimensis, Cinnyris venustus falkensteini and many others. Only once did I meet Cossypha heuglini. Sometimes I met in these districts Dioptrornis fischeri, Euplectes capensis xanthomelas, Fycnonotus tricolor fayi, Colius striatus ugandensis and others, which are not strictly confined to any special locality — even if they appear in general to prefer now this, now that — but are found a little every- where. In the end of the branches of the small acacias and bushes Othyphanies reicJienowi reichenowi had their nests and Hyphanturgus ocularius suahelicus was observed now and then. Very common too was J^rinia mistacea immutahilis. On the open, grass-covered shores flocks of Ibis aethiopica walked about in the company of the extremely common JBu- bulcus ibis, and Eoplopterus speciosus flew in swarms everywhere. Among the stones and knolls on the water's edge ran Erolia — 12 — minuta minuta, Trivga hypoleucos, Tringa glareola glareola^ Tringa stagnaiilis, Charadrius varius and Charadrhis hiaticula hiaticula while the Ions-legged, beautiful Himantopus h. hitnan- topus walked here and there on the bare, muddy patches looking for food. Here also Anthus rnfulus raalteni and Calandrella civerca saturatior occurred in small flocks, while Anthus ni- cholsoni longirostris and Mctacilla vidua were found less com- monly. As far as the eye could see, the surface of the water was covered with large, blue water-lilies and here and there impene- trable papyrus groves rose up on the lake. On the large sur- face of the leaves of the lilies Adophilus africanus graciously skipped about, among numerous Waders, that had also found their way out there to search for water-insects. Thousands of FuUca crisiata swam about in the carpet of flowers and when a shot resounded across the lake they all rose with a noise and splashing of water, only to disappear among the screening reed- tufts and into the cover of the papyrus bush. The little Limno- corax niger, which almost unnoticed darted away among the leaves and flowers, was just building its nest in some reed-clump, and Ardea purpurea, Buhulcus ibis and other Herons wandered around in company with Flutalea alba and Balearica rcgulorum gibbericeps' on the small islands while Chenalopex aegyptiacus and various species of ducks slowly waddled about on the out- skirts of the treacherous quagmire. Gulls and Terns circled in short and sudden turns above the lake, while high above them all Eagles and Vultures hovered on almost motionless wings. In the papyrus groves there was a splendid bird-life, but owing to the short time we were able to stay at Lake Naiwasha I was not in a position to get more acquainted with the birds inhabiting the papyrus kingdom. Various kinds of Weaver birds hopped about on the rushes and Corythornis crisiata galerita sat listless in the blazing sun, gazing into the water, while the rare Calamocichla leptorhyncha parva restlessly climbed up and down the stalks, or high above the reed-clumps tried to drown the croaking of the frogs and the grating cry of the coots with its agreeable song. Different kinds of Sunbirds were common here and Lanius collaris humeralis had, by mistake, gone astray out among the reeds. In the grass -plain on the eastern side Cisticola robusta ambigua was very common, as also was Cisticola subruficapilla aequatorialis. In the high grass we found, among other birds, Otis melano- gaster, Francolinus hildebrandti altumi, Francolinus uluensis and other francoline species. While the train stopped at Molo Railway Station, 7.940 feet, a specimen of Nectarinia tacazze and another of Pycnonoius tricolor fayi were shot. - 13 - Our next stop was at Londiani, 7.410 feet above sea-level We stayed here a few days to make our final preparations for the safari to Mount Elgon, while I spent the time in making further collections of birds. Londiani is an important agricultural centre, of which Cran worth (Profit and Sport in B. E. A. 1919, p. 269) says that "it is a prosperous little centre, nestling among the cedars, whence the main and much abused road branches off to the Uasin Guishu plateau. There is a township here, planned with an almost incredible want of skill in the centre of a swamp, while all around the ground rises into ideal sites". "The Red Book", 1919, p. 109 gives the average yearly rainfall to almost 45 inches. A few kilometres outside the township there are rather extensive, dense woods, on the fringes of which and on the bush- clad slopes Nectarjnia kilimensis, Cyanomitra verticalis viridi- splendens, Cossypha caffra iolaema and Saxicola iorquata salax were fairly common. Esirilda astrild nyansae and Estrilda nonnula also occurred in fairly large numbers in the bushes, where Colius striatus ugandensis was met with in small flocks. Dioptrornis fisheri and Euplecies capensis xanthomelas, Bails ■molitor puella and Lanius cuUaris humeralis were also seen al- most everywhere. In the depths of the forests I saw Cinnyris mediocris, the very rare Chlorophoneus ahbotti and small flocks of Lophoceros melanoleucos suahelicus, which slowly and listlessly moved among the branches of the trees. From the highest tops of the trees the varying cries of Turacus hartlaubi medius were heard and the skrill notes of Oriolus percivali echoed from different direc- tions, while Fycnonotus tricolor fayi — one of the best song- sters — was heard singing wherever we went. From the foliage of the slender twigs Zosierops virens jachsoni was often heard and Turdus deckeni elgonensis timidly flew about among the brushwood. On the 6 th May we left Londiani and started towards Mount Elgon. At first our way passed through grass country, and along the road Calandrella cinerea saturatior, Motacilla vidua, Riparia cincta cincta, Euplectes capensis xantJiomelas and others occurred quite commonly. In large flocks Drepanoplectes jachsoni was seen passing across the expanse of grass and on one occasion I shot out of a large flock 18 specimens with a single shot. Many times did we see the pairing displays of the males. At various places along the road there were pools of water or swamps where Gallinago nigripennis was found in great numbers. Cranworth says, however (op. cit. p. 414): "Londiani used to have a very good reputation for snipe, but lately this has not been sustained." Here, in the immediate vicinity of this little township, it seemed to be still common however. - u - Londiani Mountain in the neighbourhood is 9.855 feet high at its highest point and when we had fought our way over the mountain ridge we met, for the first time, other birds who were natives of this region. On both sides of the road there were enormous forests, which were sometimes superseded by bamboo. Among the birds shot here may be mentioned: Apalis porphyro- laema, which in flocks of 4—6 in number searched for insects high up among the branches, Buteo oreopJiikis, Buteo augur, Alseonax minimus tnurinus, Irrisor bollei jacksoni and £oice- phalus gulielmi massaicus. About two days' march from Londiani, towards Eldoret, when we encamped on the edge of a forest, about 9.000 feet high, on a slope covered with trees and bushes we shot out of a large flock sitting perched in the trees two specimens of Ciconia ciconia ciconia, which had surely been detained here but were now on their return to palaearctic regions. Vinago calva salvadorii and Turacus hartlaiihi medius were very common in the forests. The last 25 miles of road before reaching Eldoret pass through alternating acacia-plains and grass-plains, on the average about 7.200 feet above sea-level. In the former, as elsewhere, we met Macronyx croceus, Lamprocolius chalyhaeus chalybaeus, Anthus leucophrys very often, and in the bush-plains, which at certain places occupied small areas, Jynx ruficollis cocensi was not uncommon. In the grass-plains near the Uasin Gishu plateau I now met Urobrachya pJioenicea phoenicea for the first time, which was found here in flocks, but were, nevertheless most numerous in places where there was any water. This bird was, in contra- distinction to the majority of others bird occurring here, shy and cautious and therefore very difficult to approach within range. In the reed vegetation growing on the banks of a little stream the bird I have described anew, Cisticola tinniens sub- rufescens, was found rather commonly. This little bird was extremely difficult to discover as it hopped about among the reed-straws and it was still more difficult to find the birds shot. Thus I only succeeded in procuring two specimens. Both here and at the neighbouring locality, Eldoret, the rare and exceedingly beautiful pipit Macronyx ameliae wintoni was found, but not commonly, and everywhere I saw Myrmecocichla aethiops crypto- leuca. At Eldoret, about 75 miles' distance north-west of Londiani, we stayed two days. This place is the centre of the Uasin Gishu Plateau. This plateau is a fertile tract of grassy country a little to the North of the Equator. It has an area of some 90 miles long by 30 miles broad and an altitude of from 4.500 to 6.000 feet. The first South African settlers arrived in 1906 and now there are approximately 20.000 acres under cultivation. The — 15 - average rainfall is about forty inches. The altitude varies con- siderably. Eldoret itself is 6.842 feet, descending at the Nzola River near the main bridge to 5.880 feet ("The Red Book", 1919). Around the township — through which the insignificant River Socian flows — there are extensive grassplains, having a rich bird -life. Penthetria laticauda suahelica, Estrilda astrild nyansae, Macronyx croceus and Cisticola robusta amhigua were the commonest occurrences. In the bushes and vegetation bor- dering the banks of the above-mentioned river Nectarinia hili- mensis and Cossypha caffra iolaema were common, and among those occurring more sparingly may be mentioned Ces^icoZa tinniens suhrufescens, Nectarinia famosa cupreonitens. The road from Eldoret to Soy passes through scrub-plains, at about an average altitude of 6.200 feet and in these areas we shot, among others, Lybius bidentatus acquatorialis, Strepio- pelia capicola tropica, both of them quite common. Less common were Lamprocolius splendidus, Cerchneis tinnunculus tinnunculus, Bradornis pallidus murinus, and the bird newly described by V. Someren, Serinus pseudobarbatus. By the numerous small rivers which we had to cross there were generally larger or smaller wooded-patches and in these 1 met Musophaga violacea rossae, Lophoceros melanoleucos suahe- licus and others. A day's march before Soy there is a shallow little lake in the plains. Round the shores of this sheet of water there grows a dense and tall reed-vegetation, and in the imme- diate vicinity of the lake trees and bushes have united to form a kind of wood. One of the commonest birds in this little lake was Fulica cristata, and among ducks, Thalassiornis leuconotus and Nyroca capensis occurred in fairly large numbers. The dense reeds were frequented by Ixobrychus minutus payesi and innu- merable other birds, while in the swampy, grass - clad areas nearest the shores I met Ortygometra pusilla obscura. In the bushes and thickets Dryoscopus gambensis nyansae and Halcyon chelicuti chelicuti hid themselves and Ureginthus bengalus ugan- dae was common here too, while Poicephalus meyeri saturatus was often seen in small flocks. At Soy — about 35 miles from Eldoret, mid-way between that place and Mount Elgon — Mirafra africana tropicalis was fairly common and Corvultur albicoUis was found even in the town itself. Here and there in the vicinity of human dwellings Motacilla vidua also occurred and Cinnyris venustus falJcensteini and Chalcomitra senegalensis aequaforialis appeared in the low bushes along the small streams and rivers. During the last few days' march before reaching Elgon our route lay chiefly through bush -plains, where Eurystomus afer rufobuccalis and Corvinella corvina af finis, Lamprocolius splendi- dus^ L. purpureus amethystinus and L. chalybaeus chalybaeus were common. In the small groves sometimes found around the - 16 - water -courses Vinago calva salvadorii, Oriolus larvatus rolleti were the birds most frequently seen. Anthus rufuliis raalteni, and Anthus leucophrys, Myrtnecocichla aethiops crt/ptoleuca and Hiparia cincta cincta also occurred in large numbers. A very interesting find was also made here in the neigh- bourhood of Elgon, for it was here I shot a specimen of Irrisor erythrorhynclius niloticus, whose real range lies considerably more north. The find should thus show that the bird-life of the Elgon regions includes also elements from other zoogeographical areas, and later on in the description of the Ornis of Elgon 1 shall show how, from other faunistic provinces, additions to the typical bird-kingdom are present. Farus niger purpurascens, Icarus albiventris, Crateropiis melanops sharpei, Hirundo sene- yalensis and numerous other birds belonging to the Elgon- fauna already began to appear two days' march from the mountain. On the journey up to Elgon 214 birds were shot in all, representing those mentioned above, as well as a number of other species and forms. A short description of the Ornithology of the Eastern Slopes of Mount Elgon and some Remarks on the Mountain and its Nature. Mount Elgon i^ one of the largest extinct volcanoes in the world (according to Purvis, p. 266, the largest volcano in the world) and probably formed in the later tertiary period. It lies north of the eastern part of Lake Viktoiia, intersected by 1° N. lat. The western part with the main crater lies in Uganda, while the eastern slopes belong to Kenya Colony. The boun- dary is drawn across the highest summit, 4.636 metres (14.140 feet) (S t i g 1 e r writes in "Rasscnphysiolog. Studien in Uganda", p. 221, that the highest point is 4.382 metres and states that the crater is 1 1 kilometres in diameter) and then follows the Swam River northwards. The diameter of the mountain is about 70 kilometres and the main crater about 12 kilometres across (Lindblom: Ymer, 1921, p. 140). The rainfall on Elgon varies very much. Johnston (The Uganda Protectorate, vol. I, p. 301) says that "rain is abundant, and although it is heavier in some months than in others there is scarcely a month of the year which is without rain. The heaviest rains generally occur in January, February, March and April, October and No- vember. I should say that the average rainfall in this Forest llegion was 60 inches". The western slopes of the mountain have the heaviest rainfall. We pitched our camp at an altitude of about 6.800 feet, on the outskirts of the forests and from this point excursions — 1? - and expeditions were made in all directions. Below our camping- place the acacia-plain spread itself, broken here and there by the so-called orchard-plain, which in its turn was continued by the grass-plain. In the acacia-country at the foot of Elgon there was a rich bird-life. Neophron monachus was very common and at times they congregated in small flocks around my tent, otherwise this bird was seen, as a rule, in the company of Fseudogyps africanus africanus a,ud CorvuUur albicoUis, both of which where found in fairly large numbers almost everywhere. I found F. a. africanus breeding commonly in the trees fringing the small rivers flowing through the plains, but 1 also found its nest in the depths of the forests. Two specimens of Gj/ps ruppelU erlangeri were shot, although in these regions this bird was rarely found. Milvus migrans aegyptius and Buteo augur also occurred here. 1 also saw Helo- tarsus ecaudatus and Serpentarius serpentarius several times. Though Lophoceros melanoleucos suahelicus was mostly met with in the interior of the forests, it was nevertheless not an un- common sight to see a little family of 3 or 4 hopping about on the branches of the acacias. Among the Weaver Birds occurring in this area, Euplectes capensis xanthomelas, Fenthetria laticauda suahelica and Drepano- plectes jacksoni were those most frequently seen. Neither were Fhormopletces insignis insignis and Othyphantes reichenowi nigro- temporalis, described anew by me from Elgon, rare. Only once did I see Nigrita emiliae schistacea, and rather sparingly too did Quelea sanguinirostris aethiopica occur. Those found most commonly, however, were Macronyx cro- ceus, Dioptrornis fisheri, Frinia mistacea immutabilis, Bradornis paUidus murinus and Saxicola torquata salax, the last-named mostly frequenting the small acacias. On the dry branches of old trees Buphagus erythrorhynchus could be seen now and then, and Eurystomus afer rufobuccalis, either singly in or small flocks, kept company with Crateropus melanops sharpei. Rather common too were Corvinella corvina offinis, Lamprocolius chalybaeus chahjbaeus and L. purpureus amethystinus. In places where the trees grew thickly and brushwood occurred Dryoscopus gambensis nyansae, Fiscus collaris Jiumeralis^ Melittophagus lafresnayi oreo- bates^ Colius striatus ugandensis and many others were found. The Grrass-plain. Below the acacia-plain, orchard-plains and all other trans- itional forms between these floral areas of the eastern slopes the great, wide-spread savanna begins. In the transition from the plain to the typical savanna a few solitary trees of different kinds may be seen here and there. The climatic conditions of the various regions vary very much at different places, but accor- 2 — 18 — ding to G r a b n e r (Lehrb. der Pflanzengeograpliie, p. 140) the plain-districts have less than 150 cm. rain per annum. The more the humidity decreases the lighter and shorter will be the vegetation and the formation passes into a semi-desert, such as Vol kens describes from the foot of Kilimandjaro. But if on the other hand a mild climate with abundant or almost continuous rainfall prevails (which is just the case in the Elgon districts) then sa- vannas are formed. The long rainperiod, which in these localities lasts from May to October, is thus conducive to the genesis of plains. Real dry-weather prevails only from December to February. In the low bushes, interspersed here and there in this area, I met a number of birds that I had not seen elsewhere. Thus, TrocJwcercus albonotatus albonotatus, Elminia longicauda teresita, Anomalospiza imberbis and Eremoniela elegans elyonensis occurred, the last-mentioned, according to my observations, less commonly. Anomalospiza was found, as a rule, in small flocks but I always saw the others in solitary specimens. A not uncommon bird here too was Emberiza flavivetitris flaviventris, and at times I saw Othyphantts reichenowi niyroiemporalis, whose nest I found, both here and at other places, in the extreme tips of the slender branches. The most interesting find from this locality was the bird, Centropus seneyalensis incertus which I have described for the first time. This bird was found breeding. Further, Myrniecocichla aethiops cryptoleuca was met with very frequently; Riparia cincta cinda circled everywhere and Quelea cardinalis built its nest here and there in the giant reed- straws. In large flocks TJrobrachya phoenicea phoenicea flew across the plains in the company of Vidua serena. In the tall grass and elsewhere Cisticola chubbi, C. robusta ambigua, C. strangei Jiolubii were met not unfrequently and on some occasions even C. brachyptera brachyptera was seen. Of francolines only the rare Francolinus Jcilcuyuensis was met with in this locality. The dense forests. The vegetation on the western flanks of Elgon is very rich, and quite West African in character, the birds also having West African affinities. The eastern aspect of Elgon differs from the other sides of the mountain in being much less rich in vegetation, and in having a less abundant rainfall. There is forest in stream valleys sometimes, but more often the water-courses plunge down rocky gullies through a country which is strewn with immense boulders and thinly covered with coarse grass and the usual stunted trees of the East African wilderness (Johnston: The Uganda Protectorate, vol. 1 pp. 58, 60, 61). The dense forests on the eastern slopes of Elgon generally commence at an altitude of about 7.000 feet and follow up the slopes to about 10.000 or 11.000 feet above sea-level. In certain - 19 -- places there is no sub-vegetation, and these parts strongly recall our palaearctic woods. Other parts again — and these comprise the largest area of the forests ~ have an almost impenetrable sub-vegetation of thicket and liana, through which it is almost impossible to force one's way. Here and there small mountain streams rush along, on the banks of which huge ferns and creepers form dense groves. On the outskirts of the forests in the direction of the acacia- country JBarus alhiventris, Serinus albifrons Icilimensis, Batis moliior puella, Cinnyris reichenoivi, Anfhreptes coUaris ugandae, Chalcomitra senegalensis aequatorialis, Cyanomitra verticalis vi- ridisplendens and others were found abundantly. All these fre- quented places where the trees stood solitary and separated by smaller or larger bushes, i. e. in the sunlit and more open parts of the forests. On the banks of the small streams, where they plunged down the naked sides of the mountain, Motacilla longi- cauda skipped about, and the bushes close to the water were frequented by Ceryle maxima, while small flocks of Neisna quar- tinia nyansae flew here and there. The low trees in the open patches of the forest-glades were inhabited by Earisoma lugens jacJcsoni, Campophaga quiscalina martini, Apalis pulchella, Barbafula simplex leucomystax, Barhar tula bilineaia. The first nest I found of Turacus hartlaubi medius was situated in a thick bush on the fringe of the forest. Re- markably enough, I also found Chrysococcyx hlaasi here a few times and it was in this locality that the extremely beautiful ChloropJioneus dohertyi was shot. In the interior of the forests Turacus hartlaubi medius was one of the commonest birds, but only a few times did I see Muso- phaga violacea rossae. Another bird occurring quite as often was Coracina caesia pura. The most frequently occurring pigeon was Turturoena delagorguei sharpei, which was found almost every- where. Next came Streptopelia lugens funebr a and Columba arqua- trix. In the regions through which our expedition passed Vinago calva salvadorii was less common. In the tops of the Bodocarpus trees swarms of Boeocephalus gulielmi massaicus were seen, sharing the fruits of the trees with great numbers of Amydrus wallery elgonensis, Bholia sharpei and Cinnyricinclus leucogaster verreauxi. Up and down the rugged trunks of the aged forest-giants climbed Gymnobucco bonapartei cinereiceps and in like manner Campothera taeniolaema and Ben- dropicos lafresnayi lepidus were often seen. From the dense foliage the notes of Oriolus percivali were heard, which bird was found in large numbers, and Apaloderma narina narina tried to hide its bright colouring among the kingdoms of the flowers and the leaves, where also Zosterops virens jacksoni in small flocks scrambled with hissing cries on the outer tips of the branches. In flocks of 4 — 6 in number (sometimes more) Irrisor bollei 2* — ^6 — jacksoni flew laugh iug and boisterous fram tree to tree and an opportunity was afforded me to get an insight into the home-life of this bird. This Wood -Hoopoe was, for that matter, one of the commonest birds, seen almost daily on our jourueyings in the forests, whereas Ehinopomastus cyanomelas schalowi was less common. Bycanistes suhcylindriciis frequently was both heard and seen, but it was exceedingly difficult get near it, though I was fortunate enough to disclose some interesting (perhaps non- coincident) features in the life of this Hornbill. In the more unapproachable and remote places in the depths of the forest I found Turdinus pyrrhopterus elgonensis, described anew by me from Elgon. Alcippe ahyssinica ahyssinica, Telophonus australis emini, MelocicJda mentalis amauroura and several others. Where bushes and thickets formed an almost impenetrable confusion the finest songsters of the woods sang their various melodies: Fycnonotus tricolor fayi, J^hyllastrephus tephrolaemus kikuyuensis, I'll, cahanisi succosus, Andropadus gracilirostris chagwensis, An- drop, latirostris eugenius. and higher up among the dry branches Alseonax murinus murinus, Muscicapa infulata and Terpsiphone perspicillata suahelica were catching insects. Out of sight or seen only with difficulty the Honey-guides flew from tree to tree, and from the forests of Elgon the follo- wing were brought home: Indicator indicator, the commonest of the representatives of this family, Indicator variegatus variegatus and the very rare West-African Indicator conirostris conirostris. In open patches in the forest, where the ground was covered with bushes, or in glades I found among others, Apalis cinerea cinerea, the rare Hyphanturgus stephanophorus , Cryptolopha mackensiana^ Laniarius liihderi, Cossypha heuglini, C. caffra iolaema and once a single specimen of Schoenicola apicalis. In and below the forest-belt on the eastern slopes of Mount Elgon, where the well-known caves are situated, long stretches of the ground is often bare and covered with large and small boulders. On and around these boulders Thamnolaea albisca- pidata suhrufipennis occurred sparingly. On the walls and roofs of the caves hung numerous nests with eggs of Hirundo ango- lensis, seemingly rather common in such localities, though not so common as Hirundo senegalensis, which occurred both here and elsewhere. In the neighbourhood of such caves Lyhius hidentatus aequatorialis, Cuculus solitarius and Coccystes cafer were also shot. Eastern slopes of Elgon up to about 13.000 feet. It may be said of the eastern slopes of Elgon, that they are forest-clad up to about 12.000 feet above sea-level. The dense forests extend right up to about 10.000 and exhibit for the most part the same picture as on a lower level and one also finds — 21 - the majority of the previously mentioned forest -birds up here. Already at an height of about 8.400 feet one meets with small mountain meadows, in which, among other birds, Anihus rufulus raalteni is not rare. On this altitude I even found a rufous form of Caprimulgus natalensis, which for the present I place under C. c. chadensis. Here too Amydrus morio riippelU occurred in large flocks. As far as the dense, continuous forests follow the slopes Columha arquairix, Tiiracus hartlauhi medius, Dio- ptrornis fischeri, Cinnyris reichenowi, FoeocepJialus gulielmi nias- saicus, Cossypha ca/fra iolaema, Coracina caesia pura, Turdus decJceni elgonensis, Indicator variegatus, occur in great numbers, and Irrisor bollei jacksoni appeared in large flocks, numbering as many as 20 individuals. From an altitude of 8.500 feet one encounters numerous mountain streams, which sometimes plunge down abrupt preci- pices, the waters of which are beaten into fine, white foam before they reach the bottom. The ground -vegetation now begin to assume another character, pulpy, thick-leafed species of Semper- vivum and Sedum becoming more and more abundant. With reference to the frequenc occurrence of water-courses I may cite Jackson's words (The Uganda protectorate, vol. 1, p. 60): "With the aid of these cascades Elgon might (in addition to its fertile soil, paucity of native inhabitants, and absolutely healthy climate) some day become the seat of a most powerful commu- nity of Europeans, who would be able here to generate electri- city which could subserve half East Africa." The higher one ascended, the thinner the forest became and the sub - vegetation denser and taller. At an elevation of 9.000 feet some Serinus flavivertex flavivertex were shot out of a large flock, while Serinus striolatus ugandae was here a very common bird, frequenting the bushes. A specimen of Buteo augur was also found on these wooded slopes and I saw this Augur Buzzard right up to 12.000 feet. Further, in this zone Apalis porphyrolaema^ Tarsiger orientalis elgonensis, Sradypterus cinnamomeus and Zosterops virens jacksoni occurred, the last- named was even found in the low Erica bushes at an altitude of over 12.000 feet. Before one reached the extreme outposts of the forest on the summit, that is to say about 9.500 feet, the mountain meadows commenced to get larger and more numerous and the gradually thinning forest was interspersed here and there with larger or smaller clumps of bamboo. These did not, however, form a con- tinuous zone or region, though at times they appeared to do so, but consisted mostly of isolated patches of powerful and dense bamboo-trees, pressed in between the highest areas of the forest. The temperature up here at 10 o' clock on the night of 27th June was 49^ F. — The bird -life of the bamboos was rather poor. In between the fallen canes, which with numerous entangling- — 22 - plants, covered the ground, Cryptospisa ocularis ran about and the only other birds met here were Cryptolopha mackenziana, Camaroptera griseoviridis griseigula and Zosterops virens jacksoni and swarms of Irrisor hollei jacksoni. Where the forests and bamboo terminated there was a transition belt to the Erica zone and here bushes and small trees occurred promiscuously, mingled with solitary heather- bushes. This belt extended upwards to about nu elevation of 10.500 feet and here were found representatives, partly of the pure alpine bird- life and partly of the regions below. The Erica-ioreat is the vegetation colony which ascends highest up the mountain and in general the twisted and weather-beaten bushes and trees attain a height of about 4—6 metres, although a few trees may be even as much as 15—20 metres. Such a heather- giant measured 2 m. 28 cm. in circumference at breast height. Of the birds living in the Erica-ioie&t may be mentioned : Saxlcola torquata salax, which was however rather rare at this altitude. On the other hand neither ErancoUnus schutti schiitti nor Cisticola prinioides prinioides were uncommon. Only a few times did I see at 11.000 feet the rare Ghloropeta nata- lensis similis^ which frequented the dry, dead branches of the heather-bushes. The boundary-line of trees on Elgou is marked by small, scraggy bushes of the -EVica-forest, and before these are reached one comes across small patches of snow. But when the last JS'nca- plant is left behind one is then within the limits of the alpine region. The Alpine Region and the Highest Plateau of Elgon. The vegetation in this region closely resembles the Alpine flora of Kenya, Kilimandjaro and Ruwenzori. There are the weird lobelias and the giant groundsels. Snow falls on these highest points but does not lie long. (Johnston: The Uganda Prot., vol. 1 p. 61). Large and small boulders and stones here lie strewn among the grass and plant vegetation or along the sides of the numerous deep gullies, in the bottom of which, as a rule, a little river or brook flows along. A few small, stunted bushes have also strayed here, and in a few places where the streams run smoothly along small clumps of shrubbery have been formed. Along the banks of these streams grow tall Loheliae and giant Senecio Johnsioni, which, remarkably enough however, attain their grea- test size and most imposing dimensions on the highest plateau of the mountain. The characteristic plants of this region are bushy species of white, red or yellow flowered Antenaria. Everywhere on the — 23 — . ground there are swarms of small, dark-brown rodents, whose tunnels and holes open up between the tufts, and the heaps of excrement bear witness that these animals are extremely numerous. The only birds I saw here were Cisticola prinioides prinioldes, Finarochrou sordida rudolphi and Nedarinia tacazse, all of which were common. Fig. 1. The crater-lake on the highest plateaujof Mounts Elgon. (The plants in the foreground are Seneeio Johustoni.) Some hundred feet below the highest point of Elgon there is in a lateral crater a plateau with a lake about a couple of hundred metres long and some 150 metres wide, and in addition to this lake there are a few other smaller bodies of water. The shore on the side of the lake facing the highest summit of the mountain rises abruptly and is covered right up to the ridge with tall and vigorous Seneeio Johnstoni and other plants. Up here, at an altitude of about 13. 800 feet, the three last-men- tioned birds were also common, and here and there Amydrus morio riippelli could also be seen flying about. Only one specimen of this bird was shot. High above the summit soared a couple of CorvuUur albicollis and in the icy water of the lake swam a — 24 — pair of Anas sparsa and out of the sedge-vegetation that skirted the lake at certain points a GaUinago nigripennis rose into the air. The ornithological collections from Elgon contain in all 628 specimens. The Zoo-geographical Relations of Mount Elgon. Opinions may perhaps differ with respect to the zoo-geo- graphical position of Mount Elgon. As already pointed out the bird-kingdom on the eastern slopes towards Uganda is of a more West-African character but with respect to the eastern slopes which lie within Kenia Colony (British East Africa) one can scarcely make such an assertion. Reich enow has named the easternmost province of the West-African region the Central Africa Lake-district, which includes the countries round Albert Nyanza, Albert Edward Nyanza, Lake Kiwu and the northern parts of Victoria Nyanza and so on. Now Elgon being situated just north of Victoria Nyanza it is questionable whether it should be reckoned to the Central African Lake-district or not. On the map which R e i c Ji e n o w has appended in Vogelf. Mittelafr. Seengeb. and on which he has given the extent of this province, the boundary seems to run south and west of Elgon and the old volcano should thus fall within the East- and South-African steppe region (at least the eastern and north-eastern slopes). Thus the Elgon neighbourhood should form an intermediate link between the West-African forest region and the East -African steppe region. And in respect to the bird-life this seems to be the case. During the months our expedition spent on Elgon we did not, it is true, procure so many birds of West-African affinity. Still, we shot Cryptospiza ocularis^ Turdinus p^jrrJwpterus elgonensis, Miisosophaga violacea, Gymnohucco honapartei cinereiceps, all of which are previously known from East Africa. On the other hand, Indicator conirostris conirostris i\nd Centropus senegalensis incertus have not been found before so for eastwards as Elgon or any- where else in the eastern steppe regions. The former is a pure forest-bird, the latter an inhabitant of the plains. The investi- gations made during the last few years into the ornithology of Central Africa have so often shown that quite a number of forest- birds, previously only known from West Attica, even occur in the forest round the high East African mountains (Elgon, Kenia, Kilimandjaro and others) with closely related or similar birds, but are not found in intervening regions. L o n n b e r g (K. Sv. Vet. Akad., Arsbok, 1918, p. 260) explains such problems of discontinuity by assuming that a more or less contiuous forest once covered the whole of the area in which these animals now live and that the scattered forests left are only the remains of — 25 — that once huge wooded area. Later, however, considerable cli- matic changes took place, which most seriously effected the East- and South African suhregion and the forest died out in certain tracts. There arose then the steppe-regions which continued to expand and the huge primeval forest was in this manner cut up as it were, into larger or smaller formless blocks of forest which continued to exist around the great mountains. Here in these forest-islands the animals which had previously had a more uni- form distribution over the whole of Central Africa were now isolated and confined, almost in the same manner as the re- presentatives of land-fauna on islands. And these forest ani- mals — mammals and birds — are thus relicts in forests which are the remains of the once huge continuous, primeval forest, and this division of the forest has given rise to the formation of races analogous to that existing on islands in the ocean. This interpretation of Lonnberg of the presence of West- African mammals and birds in East Africa is undoubtedly correct and throws light on many different problems of discontinuity in the Ethiopian fauna. The writer in question confirms his opinion with a number of indisputable proofs, which I have no occasion to repeat in this connection. Reich enow's opinion (Vog. Afr. 1 p. LXXXIX) that the mountains of Atrica were sticking up like islands during a period when the African con- tinent was covered by the sea may, as Lonnberg (op. cit.) points out, also be applied, but in a different manner. But Elgon has not only relations with West Africa in respect to the composition of the avi- fauna, but also with South Africa, inasmuch as elements coming from the south have here their northern boundary. Thus, from the eastern slopes of Elgon, in the vicinity of Nai-Swamp, a specimen of Lobivanellus senegallus lateralis, was brought home. P'urther, Irrisor erythrorhynchus niloticus was shot on Elgon, which shows that birds previously only known from North Africa also have their southern boundary in these regions. It would be rather a lucky chance if our expedition, during the relatively short time we stayed on Elgon, had procured all the different birds, which really belong to other zoo-geographical sub-regions but, from some cause or other, are nevertheless stationary in the locality. There are surely many others, which future studies of the ornis of the mountain will establish. But already from the few discoveries made one might certainly assume that the bird - kingdom of Elgon includes elements of very different origin, and that the avifauna, here therefore exhi- bits a mixture of forms from many different zoo-geographical regions, and consequently the number of the so-called subtile forms will, of course, be unusually great. That Ardeola idae, which is otherwise an inhabitant of Madagascar and South Africa, was shot in the vicinity of Elgon — 26 — must perhaps be considered as a mere chance. Frona any point of view the find is none the less of some interest. At Victoria Nyaiiza. Before reaching Victoria Nyanza we stayed for a few days at Lumbwa, a few miles west of Londiani, on the Uganda Railway. This place lies 6.220 feet above sea-level, but the surroundings are at some places 7.000 feet and over. Only a few birds were shot in this locality: Lanms collaris Jmmeralis, Campephaga iiiifra nigra, Lanuirius stdplmreipectus suahelicus and Telophonns senegalus eryihroptertts all of which we found in the valleys co- vered with acacias and brushwood. Later on I stayed some time at Kisumu, formerly known as Port Florence, the terminus of the Uganda railway. This town lies at an elevation of about 3.760 feet at the eastern end of the Kaviiondo Gulf, Victoria Nyanza, and has the most rainy periods in December, February, March, Ai)ril with an average monthly rainfall for a period of six years of 6 79, 5.02, 6.27, 6.88 ins. respectively, and a total of 47 39 ins. 1 arrived here in the dry period, therefore a great number of the birds shot are in moult. In the innermost parts of the Kavirondo Gulf there are extensive, alnsost impenetrable i)apyrus groves and inside these, where the shore commences, is a narrow belt hlled with bushes and brushwood. Actophilus africanus, Tringa hjpoleucos, Bu- bulcus ibis, were very common in the reeds and along the shores, and although it was in the end of the month of August a fe- male specimen of the first-mentioned species had well developed eggs in the ovary. In the brushwood Streptopelia decipiens per mistily Chalcomitra senegalensis aequatorialis, Nectarinia enjthrocerca, J^loceus melanocephalus dimidiatus, Alseonax infulatus, Serinus dorsostriatus dorsostriatus and others occurred in great numbers. Such an abundance of Honey Birds as was found here I never saw anywhere else. As my wanderings in the districts only lasted a few days it goes without saying that I am not in a position to give any- thing like a complete description of the bird-kingdom, but must be content to mention the birds shot during my excursions. The exceedingly beautiful Laniarius erythrogaster erythrogasier hopped about in the dense brushwood and Columba guinea longipennis was seen occasionally. At certain points the steppe-country reaches down almost to the lake itself and Small flocks of Oena capensis were seen flying back and fore between the low bushes growing here. — Sorella emini-bey, Amadina fasciata alcxandri, Anomalospiza iniberbis. Halcyon leucocephala leucocephala and many others also occurred here, though less commonly. Colius striatus ugandensis — 27 — and Spermestes cucuUata were seen almost everywhere, and in the branches of the acacias Macronyx croceus was seen and heard. In large flocks Neophron monachus and Corvus alhus kept company, both on the shores and in the acacia-country, I even saw them very often in the streets and open places of the town of Kisumu itself. Here and there Motacilla vidua tripped about fearlessly and Passer griseus ugandae appeared both in the scrub-country and on the shores of the lake. Before leavinf:^ Victoria Nyanza I made a trip to Kendu on the Kavirondo Gulf and stayed there for four days in order to complete my bird-collections. On the whole, the natural and climatic conditions at this place are the same as those at Kisumu, and therefore there is no need of my touching upon them again. Almost all the birds observed and shot at Kisumu were also found here. But several others were shot as well. One of the commonest species was Ceryle rudis rudis, which was found in large flocks on the shores of the gulf, where also CorytJiornis cristata galerita and Halcyon leucocepliala leucocephala were met with. Very numerous were Thresh, aethiopica, Larus cirrocephalus, Anhinga rufa rufa, Buhdcus ihis^ Gelochelidon nilotica nilotica, Uydrochelidon leucoptera leucoptera and others. Limnocorax niger, Balearica regulorum gihhericeps and Hagedashia hagedash nilotica were not uncommon here. The waders too were numerously represented by a great many species, among which may be men- tioned Hoplopterus spinosus and GLareola ocidaris, which did not however occur so abundantly as Tringa glareola glareola, Erolia niinuta minuta and Tringa ochropus ochropus. The latter were seen everywhere on the muddy shores, where, in the com- pany of Oedicnemus oedicnemus vermiculatus it tripped about in large flocks. Alopochen aegyptiacus was also very common. In the reeds, which in some places were very dense and tall, swarms of Pyromelana nigrifrons flew about and in the trees fringing the shores I found Hypochera uUramarina purpurascens and numerous pigeons, among which may be mentioned, Sireptopelia de- cipiens perniista and Sireptopelia fulvopecioralis, the latter described by me from this locality. In the dry grass-plains were found Charadrius asiaticus asi- aticus, Oenanthe pileata livingstonei, Scopus umbretta hannermani and the bushes on the fringes were frequented by Passer griseus ugandae, Ploceus melanocephalus dimidiatus, Vrohrachya phoenicea phoenicea, Anomalospiza imherhis. Likewise, Anthus rufulus raal- teni, Pyrrhulauda leucopareia and many others were common in the grass-country. Among the Honeybirds Chalcomitra senegalensis aequatorialis and Centropus super ciliosus, Ureginthus hengalus ugandae, Dicrurus adsimilis divaricatus and Pycnonotus tricolor fayi were often met with, and now and again Ploceus ahyssinicus femininus.

These two specimens were shot by Director L o v e n while on a shooting trip in the Thika districts. Being unable to make an examination on the spot I give Mr. Lovcn's brief description: "The male: head, bill and legs milk-coloured with a bluish tint; metatarsus and toes milk-coloured, somewhat pinkish in front. The female: head and neck grey with a greenish hue, bill dark grey, dark-coloured, darkest at the edges; legs and toes light grey, scales brownish grey." This Ostrich was common in the regions around Nairobi and further southwards and I frequently saw them running about the plains in large flocks. They were plentiful in the Game Reservations.

The Darters were very common in the regions of Kendu, where they could he seen in small flocks flying along the shores. Sometimes they searched the primitive fishing devices erected by the natives or Hindus, and it was a common sight to see a stolid and noisy darter on a pole out in the water. They are, as a rule, very shy and cautious and at the least sign of danger they stretch their long necks straight up into the air and turn their heads in different directions. They fly heavily and close to the surface of the water. In the evenings they collect together, along with Herons, and settle in the trees growing in the water, when it is possible to get very near them without their flying away. Of the 5 specimens shot, at least.one d* is in full dress and this, as well as the three females, agree in coloration with the description given by Reichenow and others. All the four adult specimens, however, have the inner web of the last secon- dary supplied with a cross-fold, (like that on the outer-web of the tail feathers). — 30 -- As regards the plumage of the young bird the descriptions of different writers must be taken so that the picture may be something like complete. The young bird shot by me differs now from this description, now from that, for, according to Heuglin (Ornithologie Nordost-Afrikus Bd. II p. 2476), both the dark and light stripe from the eye is missing. In ray specimen, however, the white, glossy stripe running down the neck is found to the length of 10 cm. Further, the chin is not pure white but has a pale yellowish brown tint. 1) According to Reichenow (Bd. I. p. 96) the under part of the body is brownish white. This spe- cimen, howewer, has a greyish white, silky colour, and the lower part of the neck is light rust-coloured. The rectrices are blackish on the upper surface (without any transverse folds), on the lower surface dark-brown with dark greyish-brown tips. The respective measurements of these individuals are: wing 338 mm, culmen 80 mm, tarsus 40 mm, tail 260 mm. On account of tlie whiteness of the under surface we might be able to suspect that this specimen is A. r. novaehollandiae (Gould.), the female of which has this colour, but Hartert (Vog. Pal. Fauna, p. 1401) asks the question as to whether 9 ^^- also has this character. Even with reference to the colour of the iris, culmen and legs there is a great difference of opinion. Reichenow, for instance, states that the iris is red; Hartert that it is yellow, v. Erlanger says (J. f. 0. 1905, p. 37) that in adult birds it is grey with a yellow, then a red ring around the pupil etc., etc. In the young bird the iris has innermost a narrow white ring, then a narrow one of greyish yellow and outermost one of coffee- colour. In the four older birds the iris consisted of a yellow ring innermost, surrounded by a broader one of brown. With reference to the length of the culmen Reichenow states that it varies between 75 and 90 mm. The five Kendu- specimens have the following measurements: 1. d* 66 mm, 2. 9 76 mm, 3. 9 72,5 mm, 4. 9 73,5 mm 1. juv. 9 80 mm. Of these, the shortest one, 66 cm, belongs to an old male bird in full dress and the longest, 80 mm, to a young bird. The colour of the bill varies also somewhat with age. Thus, the young bird has a light greyish green bill, while, the bill of old birds, on the other hand, is light brownish-green. Hartert states that the colour of the legs is white, while Reichenow says that the legs are dull yellowish-brown. In a young bird just shot, they are, according to my observations, *) The shoulder-feathers are short, brown-greyish or brown-blackish with lighter streaks along the shafts. The outerweb of the greater wing- coverts, which in old birds is darkbrown, is in this specimen greyish (sometimes with a faint tint of brown). No long lancetformod feathers. - 3i - light greyish green on the upper side, while the lower side is dark grey. Old birds have the upper side of the feet light brownish green and the lower side dark grey. V. Erlanger writes (op. cit.) that adult male birds have the whole of the back black with a green wash, females on the other hand have the feathers of the upper part of the back tipped with brown. This observation is, as far as I can find, quite correct, but when the males get close to the moulting-seasou they are, as regards the colour of the back, exactly like the females. Neither is it so easy to distinguish them by the other character adduced by this writer, viz., that the females lack the black stripes along the upper part of the neck which the males have, because of the three female specimens I have from Kendu only one (pro- bably a young individual) is without them. The other two have them almost as pronounced as the cf specimen. In Cat. of Birds vol. XXVI p. 411 a character is given by means of which it is easy to distinguish between d* ad. and 9 ad., i. e. that the former has "the black at the base of the fore-neck and chest not divided from the base of the hind-neck and upper back by a chestnut band, terminating at the shoulder" while the latter has "the black at the base of the fore-neck and chest divided on each side, etc." I have myself determined the sex of my specimens and know that there is no uncertainty or doubt about this matter. Two of my specimens are in the moulting stage, the others — except the young bird — are in full dress. But the reason why we find this condition in these birds is due to the fact that in Steganopodes, Lariformes the renewal of the big feathers and the small feathers do not coincide with one another, the latter taking place rather rapidly while the former may be going on the whole year round, so that, strictly speaking, all individuals are in moult. In such cases the characterisation of the plumage must be based on the condition of the small feathers. (Strese- mann: Avifauna Macedonica p. XV.) Anatidae. Thalassiornis leuconotus Eyt. — Rchw. p.

Soy. 10 miles north-west of Soy in the direction of Mount Elgon at an elevation of about 6500 ft. there is a little lake, bordered with a rich and vigorous reed vegetation and surrounded by acacias. On the shores of and in this lake there was an abun- dance of various kinds of birds. Among the different species of ducks found here this species was often seen on the edge of the reed-belt, where, in little — 32 - flocks of about 8 or 10 iudividuals, it tried to escape discovery by getting in among the large root-stocks of the reeds projecting above the surface of the water.

The specimen brought home was shot by the icy-cold crater-lake on the highest point of Mount Elgon, about 13.800 feet above sea-level. It is rather remarkable that the ver- tical range of this water bird extends so high up into the higher zones of the alpine regions, and with reference to this species, which is really an inhabitant of the low-lying, stagnant pools, where there is plenty of algae and water-plants etc. (v. S 0 m e r e n has found the bird at Lakes Naiwasha and Na- kuru) it is not known that it occurs and breeds in the snow- regions. Both the male and female of this species were seen on the lake, but as soon as I approached the shores they flew away startled. Although they seemed to be very shy they returned, however, in a short while and I then succeed in shooting 9- At one end of the lake, where the sedge grew in knolls, I found a nest, which no doubt was or would possibly be the home of the pair. It was composed of dry straw and down. Bowker, accor- ding to Reich enow once found a nest of this bird in a hole in a tree 2 meters above the Avater, but as such a site cannot be found up here, the pair was certainly compelled to accomo- date themselves to the facilities of the locality. A week before I visited the crater-lake Dr. G. Lindblom, ethnographer in our expedition, who then made an ascent to the summit of Elgon, had seen the two birds on the lake, and it is possible that they had been staying there for some time and had thus even selected and commenced to arrange the site for the future nest. - aa — At the foot of Elgon — at an elevation of 6.800 ft — I saw this species later on in the pools and mountain rivers found there, but only two or three of them together. The female, which was shot, had rather well developed eggs in the ovary and was about to commence laying. Wing 250 mm, tarsus 41 mm. Irides cinnamon brown; bill lead-coloured with the middle part and nail black, the tip and base yellowish red; legs greyish green (the under side of the toes yellow), web black.

In flocks of from 10 to 15 in number they used to settle on the muddy shores of the gulf and, in company with Thresh, aethiopica, flocks of Buhulcus and other waders search for small animals in the mud. The birds in this district are very shy and difficult to ap- proach witbin range, as they are eagerly hunted by the neigh- bouring Kavirondo Negroes, who, from what Okoth, the chief, told me, consider them to be ''■nyama mzuri Sana" (= very good meat). Both specimens are in full dress. One has a large dark- brown breast- patch and almost white undertail coverts (some with a pale-yellow tint). Wing 360, 370 mm, tarsus 70, 74 mm.

Occurred in large flocks, from 50 to 100 in number, along the shores of the Gulf of Kavirondo, most often frequenting the small, often reed-covered, islands out in the water. Their flight is rapid but unsteady. In the company of Hydrochelidon I. leucopiera they flew, now up now down, in daring sudden turns and when a shot was fired they did not alight but flew in wide circles around the visitor. Both specimens are in full dress and the male has the fore- neck greyish -brown, the throat muddy yellowish brown. The upper part of the belly, and the flanks, are bright rust- coloured. 3 - 34 — the female, on the other hand, has the throat and fore -neck grey-coloured without any brownish wash. Besides, she has a great number of white feathers in the lores, which in the male are uniform black. Neither of the specimens, however, has the middle of the throat whitish but agrees entirely in the coloration of the throat with the picture of this species given by Pucheran, which he names Glareola geoffroyi (Mag. de Zool., Paris, 1845, pi. 57). When compared With the specimens in the Berlin Museum, collected by Fischer on the coast in Manibrui in British East- Africa it appeared that my specimen agreed fairly well with these, both as regards measurement and colour. The former had a wing-measurement of 190—200 mm for cTcf and 182—192 for 99i and even the length of the tarsi was the same as that of the Kendu-birds. V. Someren does not include the species in his "Check list of the birds of East-Africa and Uganda", 1917, although it has long ago been known from East-Africa, but Z e d 1 i tz (Journ. f. Orn., 1914, p. 622), gives the bird from the coast of south Somali. Wing, cf 180 mm, 9 190 mm, tarsus, cT 30 mm, 9 26 mm. Irides dark brown; bill black with red flanges; legs black.

It frequented the acacia-plains. Neumann (op. cit.) distinguishes Eh. ch. chalcopterus from Hh. ch. obscurus, occurring south of the equator to the Cape, which has a brown olive-grey upper surface. The former is said to have a lighter and more yellowish upper surface and occurs only in Upper-Guinea (Senegal). My specimen is almost uniform brown above. Wing 177 mm, tarsus 78 mm.

Wherever there were streams, rivers or lakes this species was common. At Lake Naiwasha, where the bird occurred in great numbers, it was generally found in the company of Tringa glareola and other waders. At Nairobi where a 9 was shot, it was seen almost every- where on the banks of the little stream flowing through the country. According to v. S o m e r e n the bird breeds in British East Africa (Ibis 1916, p. 201), and the same author in his work "Bird-life in Uganda" gives an excellent photograph from Uganda of a brooding hypoleucos. The young bird, which was shot at the Gulf of Kavirondo (at Kisumu) has a very worn dress and is uniform greyish brown on the back; some of the feathers, however, have light edges. Further, the dark and light transverse bands on the upper sur- face of the body are lacking, and the sharply defined dark patches along the shafts, which, according to Reichenow, are found in the young of this bird, are also missing.

The female, which was shot by Lake Naiwasha, is changing into the summer plumage, the male from Kendu (on the Gulf of Kavirondo) is about to assume the winter dress. In both localities this bird was common and flew in large flocks along the coasts. In other places they were observed at about the same time, i. e. the end of April and August, in single pairs, and they could be found in all phases and dresses. Still, it is not proved with certainty that the species breeds in East Africa, even if a number of facts seem to speak for it.

At this place the species was rather common, and again at Eldoret I saw some more individuals. The other specimen brought home was shot on the eastern slopes of Mount Elgon, about 13.000 ft. above sea -level. On different occasions later on I observed the bird at other ele- vations. Still, it seems beyond doubt that G. nigripennis is a pronounced highland bird, which even occurs in the alpine region where only a few icy -cold mountain streams can offer the bird the required possibilities of existence. Wing 130 mm, culmen 64 mm, tarsus 30 mm. The measurements given above would seem to suggest that the specimen in question belongs to G. media. The length of the culmen expecially agrees more with that bird, but the indivi- dual is a young bird, which in other respects is quite in agree- ment with G. nigripennis., whence there is no doubt as to its identity.

It frequented the acacia- plains, which at some places reaches down to the shores of the lake, where it ran about in the tall grass and knew well how to lie concealed. It was seldom seen to fly and when this happened at any time it would soon settle again about 50 to 100 yards from the spot from where it took wing. The female, which was shot at Lake Naiwasha, has the following measurements: wing 360 mm, tarsus 130 mm, culmen 40 mm, tail 160 mm. According to H e u g 1 i n the length of the bare part of the tibia in this species is 55 mm but in the closely related Otis hartlaubi, it is 64 mm. It this 9 specimen the bare part of the tibia is 67 mm. and in the male specimen, shot in the neighbourhood of Mount Kenia (Tana river) it is only is 57 mm.

The Crowned Cranes were fairly common in the marshes below the eastern slopes of Mount Elgon and here, as at every other place where 1 came across them later on, they were not shy, but would permit one to get close to them before they rose with heavy, slow strokes of the wing. For the most part they were seen in pairs, but once (in the middle of September) I saw outside Nairobi a large flock, about 50 in number walk- ing in the cultivated land, searching for insects. K o t h e (Z. Erg. p. 329) relates that at Misama on Aug. 24th he saw several hundreds together. They were common everywhere at Kendu (on the Kavi- rondo Gulf) and also at Lake Naiwasha.

The two specimens that were shot in the month of April are from Lake Naiwasha, the other two from Kisumu, in the innermost corner of the Gulf of Kavirondo. In both these loca- lities the bird was very common, frequenting the reed -belt, where the leaves of the I^ymphaea covered the surface of the water. The young birds are not reddish brown on the black like the adults, but have distinct greenish brown markings. Both have the foreneck golden -yellow but not so deep as the adult. The one from Naiwasha has the under parts of the body white, but the flanks are reddish-brown, the one from Kisumu is more reddish -brown with numerous white feathers here and there. — 41 — The frontal- patch is also considerably smaller. The length of the culmen from the edge of the frontal-patch, of young and old birds is as follows: juv. ad. 9 47 mm. 56 mm. 9 9 45 rnm. 53 mm. cf It seems also as if the length of the wing and tarsus in the young bird should, as a rule, be greater than in adults. In young birds the superciliary stripe is not always white but some- times yellowish brown or straw-coloured, nearly the same colour as that of the foreneck. This stripe then continues along the dark portion of the head and neck as a lateral border to the white patch of the throat. The frontal patch, which becomes larger with age and in old individuals, extends far behind the eyes, later on replacing the superciliary stripe. In the four individuals the respective measurements are as follows: wing tarsus wing tarsus cf juv. 167 mm. 73 mm. cf ad. 153 mm. 64 mm. 9 juv. 173 mm. 68 mm. 9 ad. 160 mm. 68 mm.

On the 22. 4. in a tussock among some tall rushes out in the water, I found a nest, which then contained two eggs of a light yellowish brown colour with small and large dark brownish spots. Although the hen had already begun to lay her eggs both the male and female were continually occupied in carry new material to the nest. The noteworthy thing was, however, that above the depression itself there was an arch or roof, consisting of large and small dry rushes and stalks. Whether the birds themselves had arranged this superstructure or whether it was a temporary accumulation I am not in a position to say, as this was the only nest I saw of this species.

About 30 miles north of Eldoret about 6.500 feet above sea- level there is in the acacia-plains a shallow, rush covered little lake, surrounded for the most part by high banks. Only at one spot does the shore slope downwards and here the lake passes into a little swamp, where among other swamp and water-birds, this bird was shot. The bird is shy and cautious and mostly keeps to the ground, where it darts in and out among the rushes. When one gets too near it, it rises and flies, about ten or twenty yards, only to drop to the ground as if hit by a shot. Wing 85 mm.

R e i c h e n o w states (after Andersson) that the species in question lies concealed during the day-time, only coming out in the mornings in search of food. This was not' the case here, but one could see them everywhere in the lake at any time of the day. If a shot was fired at them hundreds and sometimes many hundreds of them would rise with a scream at the same time to seek protection in the papyrus groves. Also in the lake just mentioned where Forz. pus. obsc. was shot, this Crested Coot was the commonest of the birds. Wing 213, 216 mm, tarsus 62, 67 mm.

In flocks of 10 to 20 in number I often saw them walking in the short, dry grass on the acacia plains (in the month of April) or, together with Buhulcus, following the cattle. They were very shy in these parts and I did not succeed in getting within range. At the Gulf of Kavirondo in Victoria Nyauza, where they were also numerous, they frequented the plains and here I had an occasion to shoot 3 young birds and 1 adult. During the hottest hours of the days they are mostly found on the shores or on the sand-banks in or near the water, but in the mornings and evenings they take to the grass-plains or cultivated fields to look for food. The full-grown male has a wing-measurement amounting to 385 mm, tarsus 110 mm, culmen 170 mm and is in full dress. The outer-web and tips of a number of the large, outer wing- coverts and the feathers of the flanks are light ochre-yellow. One of the cf juvenile birds, which has almost the com- plete adult dress, with secondaries and primaries of a steel-blue and green glossy colour, the latter beginning to get abraded and defused, still has the neck completely covered with small feathers. On the throat these are quite white and worn at the edges, so that often only the shaft and small fragments of the web are left. The head, sides of the head and cheeks are thickly covered with longer, unabraded black feathers, which become thinner towards the back parts of the neck. Both on the head and the neck there are numerous white feathers sprinkled among the black ones. In the two somewhat younger birds the feathers of the crown and back of the neck are not black but dark-brown and on account of their age, larger and whole. Irides dark-brown; bill and legs black. ^ Hagedashia hagedash nilotica Neum. — Ornis, vol. XIII, p. 193. Nganga . . . ki-kavirondo. 1 (5 ad. 22. 8.; 1 p ad. 22. 8.; Kendu. In the Gulf of Kavirondo this race was rather common, frequenting the trees fringing the shores. — 44 — The male individual is in full dress, the female is in rather worn dress and has just commenced moulting, the lower parts of the body being predominantly brown, while in the male they shade into grey, and a number of the feathers are bordered (at the points) with a yellowish-brown seam. Neumann has (op. cit. pp. 190 — 196), separated four forms, which are mainly distinguished by the length of the culmen, for the characters ''light grey", "darker grey", "still darker grey", etc. are not conclusive in such cases. R e i c h e n o w (Mitt. Zool. Mus. Berlin, 1910—11 p. 74) considers that these four forms are difficult to limit because they pass into each other and the length of the culmen varies with age and sex. For, the male specimen before me is dark grey, the female light greyish brown and yet they were shot on the same day. Apparently the grey colour varies in depth both with age and season.

One evening when camping at a spot — about 42 miles north of Londiani in the direction of Eldoret — at an elevation — 45 — oi about 8,000 feet we observed a large flock of storks, about 30 to 40 in number, which had alighted in some acacias to roost. As a rule the storks have already migrated from Africa and arrived in Europe by this time and it is therefore noteworthy that as late as the 9 th of May they had not left East-Africa. On the 16 th April I saw a few in the neighbourhood of Nairobi and, at the end of the same month, at Naiwasha. K 0 1 h e mentions (Zool. Erg. d. Exp, d. Herrn Hauptm. Fromm 1908/09 nach D. 0.

A male, in full dress, of this beautiful Heron was shot at the lake just mentioned, 10 miles northwest of Soy in the direc- tion of Elgon. When I sent the natives into the reeds, which everywhere grew to a great height and were difficult to pene- trate, it flew along the surface of the water some 10 metres and then dropped into the shallow water on the beach. The dark -red -brown feathers of the neck are sprinkled with a few dark, blackish ones, but otherwise the dress approa- ches the description of that of the Sansibar-specimen given by Reichenow. Reichenow doubts whether we are entitled to establish geographical sub-species of this species. If only colour diagnoses were the foundation of such a division it would perhaps be audacious in the present case, but as the various measurements and a number of the other characters vary there are probably more well-founded reasons than in some cases where a far- reaching division has been made on account of very small — mostly purely subjective — differences.

Of this interesting species of Heron, whose real home is Madagascar, a cT specimen was shot below the eastern slopes of Mount Elgon, at about 7.000 feet above sea-level. It was found on an open plain near a little brook, where the natives had recently burnt all the vegetation, looking for food among the charred remains of grass and bushes. Only this one was seen. No doubt it must be regarded as a mere accident that this species had strayed so far from its real native country and the fact of its having found its way as far up as the Elgon terri- tory is not easy to explain. In comparing this specimen with the specimens in the Berlin Museum it was seen that the specimens found there are more grey on the upper surface and not quite so rusty-brown on the neck. — 47 -=- Total length wing culmen tarsus tail 380 mm. 210 mm. 59 mm. 58 mm. 52 mm.

This dove was met with at various places: Eldoret, Soy and the eastern slopes of Mount Elgon at an elevation of 6,500 and 8,000 feet above sea -level. One specimen was shot in the arboreal vegetation bordering the banks of a little brook — in the vicinity of Elgon — flowing through the acacia steppe. Two of the specimens, from the 15th and 26th May in the neighbourhood of Mount Elgon, had only a slight tint of the grey band on the back and the colour of the legs was a dirty red, whereas, on the other hand, in all the others it was a beautiful coral-red. — 48 — The bird was common on Elgon and occurred both in the forests and in the small vegetation colonies, which as a rule, follow the small or large waterways in the acacia steppe. They were frequently seen in large flocks. Quite considerable differences occur in this dove. Some have the back and the whole of the upper surface of the body behind the grey neck- band (even the upper tailcoverts included) yellowish olive-green, others greyish green. In some the grey neck-band is pale and inconspicuous, but in the majority it is pronounced. In a few specimens the rectrices are bordered with green, but in the majority this border is lacking.

This dove was found quite commonly almost everywhere. In the dense forests around Nairobi large flocks were seen in the middle of April. On Mount Elgon I met with this species as far up as 9.000 feet above sea-level. It frequents the dark and moss-clad trees, where it will remain quite still until one gets right up to it. Congreve says of this bird (Journ. East. Afr. and Ug. N. H. Soc, vol. Ill, No. 6, 1913 p. 47) that it is the commonest pigeon in the Mau forests and probably in the other forests of British East Africa. The 6 Elgon specimens are rather diflerent from each other in colour. Erl anger has (J. f. 0. 1915, p. 115) already remarked — 49 — that the various tones of colour of the under surface is due to individual variations, which is probably true, for I have in the same month shot birds with a dark, brown-violet under surface, others with a light greyish red belly etc. Some have the crown and neck bright light-grey (the commonest state), others have these parts dark greyish-blue (almost the same colour as the young bird). In the specimens from Elgon the wing -measurement for cfcT is 235—236 mm., for 99 213—227 mm. In those from the Nairobi regions the measurement for cfcf is 210 — 227 mm. In spite of this difference in size between cfd^ I do not consider that I am entitled to separate the Elgon specimens from the Kikuyu. Lonnberg has already shown (Birds coll. Swed. Zool. Exp. B. E. A. 1911, p. 44-45) that C. a. arquatricula, — which according to Oberholser should be the one occurring in Central Africa — cannot be regarded as a form varying from arquatrix, and a number of my specimens both from the Nairobi regions and Elgon prove one thing, that the difference in size is not a constant occurrence, whence Lonnberg's opinion is un- doubtedly correct. A young 9 bird from Elgon, shot on the 6. 7., agrees rather closely with the description of such a bird given by Lonnberg (Arch. f. Zool. Band 9, No. 14, 1915, p. 3). Still the chin and the feathered part of the mandible of the specimen in question are quite rusty-brown and all the feathers of the throat are bordered with rusty-brown. The length of the wing is 127 mm. Irides yellow-yellowish grey, bill and legs citron-yellow. Stigmatopelia senegalensis aequatorialis Erl. — Journ. f. Ornithol. 1905, p. 118.

The specimen from here has the following mea- surements: Wing 132 mm. Tarsus 19 mm. Irides cofll'ee-coloured. Even at Kisumu the bird was one of the most common, and I frequently saw it on the outskirts of the town, where it ran about the roads looking for food. Wing 137 mm. Tarsus 19 mm.

In the coast-land at Mombasa this pigeon was one of the commonest and was frequently seen in the cocoanut groves and on the outskirts of the forests, fringing the open fields. 4 — 50 - In one specimen the chin is distinctly white, whereas in the others it is a beautiful, pale wine-colour. Further, the occiput, fore-neck and breast are light wine-coloured, while, on the con- trary, these parts in the Kikuyu and Ngong specimens are darker, distinctly shading into rusty-brown. They were all shot in April and were in about the same stage (except one juv.). The specimens from the Nairobi district (Kikuyu, Ngong) are very different from one another. Of those from the latter place, one (in moult) has the back and sides of the head almost brownish red and the upper tail-coverts greyish-brown, the same colour as the back, while the other (also in moult) has the back and sides of the head wine coloured, and upper tail- coverts bluish grey. In the Mombasa specimens the iris was bright reddish-yellow, but in those from Ngong and Kikuyu it was dark-brown with a red ring nearest the pupil. The bill almost black in all.

In the Mombasa specimens the lower rump and undertail- coverts are deep-blue, but in those from Kikuyu and Ngong they are considerably darker, while in the Elgon specimen they are almost of the same dark-grey colour as that of the under wing- coverts. The difference between the Mombasa and the Elgon specimens is so pronounced that even this character alone should be enough to establish a special Elgon sub-species. The same thing is noticeable with respect to the wine-red colour of the neck, crop and breast, i. e. considerably darker in those shot inside the country; and in the Elgon-form the rusty- brown feathers are more numerous than the pale wine-coloured ones. In the Elgon specimen, again, the crown is dark grey and not pale grey as in those from the coast or the Kikuyu country. The lesser wing-coverts, which in the Elgon specimen are all predominantly brown, are greyish in the other specimens. Reichenow states, p. 410, that the young bird has rust- coloured edges to the feathers of the head, throat etc. This is also in agreement with the juv. specimen I have, but all the primaries are rust-coloured in the points and also along the edge of the outer-web as well, whereas these parts are greyish-white in a full-grown individual. Grote (Journ. f. Ornith., 1921, p. 423) names specimens from Ukerewe-Island erythrophrys Sw. According to Grant (Ibis 1916, p. 42) this bird is known from West Africa and Fernando Po, but probably Grote bases his opinion on statements made by Zedlitz (Journ. f. Orn., 1914, p. 644 and 1916, p. 113), who gives the range of erythrophrys as extending from S. Abyssinia, Central, East, West to South Africa. The true Streptopelia s. — 51 — semitorquata from Abyssioia would, according to a statement made by Prof. 0. Neumann, as a rule, have a winglength of almost always over 190 mm. (maximum about 198 mm.), but the East- African bird is smaller and thus not the typical semitorquUta. — It agrees rather well with the Seaegambia-bird erythrophrys, and I therefore think, that Z e d I i t z and G r o t e are right, when calling their East-African specimens erythrophrys. Therefore, on the strength of the above-mentioned facts concerning the differences between Streptopelia semitorquata semi- torquata Riipp. from the coast-land and the Kikuyu region and the Elgon form I think 1 am fully entitled to determine this form as a new one, which I name: Streptopelia semitorquata elgonensis Granvik. 1 Q ad. 18. 7. Eastern slopes of Mount Elgon 7,000 feet. Differs from Streptopelia semitorquata semitorquata Rupp. in the following respects: 1.

Neck, fore- neck and breast dark wine-coloured with rust- crown tinge. 4. Only a few of the wing -coverts have a pale, sometimes scarcely discernible, shade of grey. wing: 190 mm. total-length: 310 mm. culmen: 18 mm. tail: 138 mm. tarsus: 25 mm. This pigeon lived on the edge of the forest where the expanse of the acacia steppe began. Another specimen of this bird was shot which corresponded perfectly in colour and design with the individual broivght home. Irides reddish yellow. Bill dark- brown (almost black). The colour of the legs dark-reddish blue. When looking over the large collection of S. semitorquata at the Museum in Berlin, 1 found, it is true, a specimen from Bukoba 12. 12. 1920 which has character 2 above, but the neck is wine-coloured. Not a single individual, however, had a grey breast and grey belly. Every true S. s. semitorquata, in full dress has a dark wine-coloured belly. Stigmatopelia lugens funehrea v. Someren. — Bull.

Often remained quite still until one got to within a few meters of it. One of these two specimens was a full-grown male with swollen testes. The other was a younger individual, the tips of the grey feathers on its belly being pale rust- coloured. The grey colour of the crown and the sides of the head is also lighter in the latter than in the fully developed male. Otherwise it agrees in every respect with the one in full dress.

In large flocks it frequented the low trees and bushes growing at the water's edge or out in the water. Z e d 1 i t z (J. f. 0. 1914, p. 644- 654) discusses the family Turtur very minutely and distinguishes 7 forms belonging to the decipiens group. My specimens all belong to the above- named. Reich enow states (op. cit. p. 808) that permista has the white parts of the lower part of the body widely distended. One of my specimens agrees with tbis, but another has a predominantly pale greyish brown tint on the lower part of the body. The young bird strongly puts one in mind of the young of S. capicola tropica, but has all the feathers of the head and neck and those of the fore-neck and breast bordered with brown ish grey. The flanks in the former are greyish blue, but in the latter they are yellowish white or of a pale wine-coloured shade. The outer-web of the extreme tail-coverts are, however, as in old birds, predominantly black, whereas, the young bird of S. c, trop.^ on the other hand, has the outer -web generally white. The measurement figures for the length of wing in my specimens do not exactly coincide with Erlanger's (cfcf 160—165, 99 153— 155 mm): they are for the 3 cTcf 155—157 mm. (the young bird, 145 mm).

The present specimen has extended, stilliform spots and is purely white on the breast. The Berlin specimens are, moreover, larger. This specimen has a wing length of 134 mm. and tarsus „ „ 41 mm.

The first time I saw this beautiful buzzard was in the forests around Kiambu, in the neighbourhood of Nairobi, where, on the edge of a forest, a pair had their large nest, built of strong branches. For several days 1 saw one of the birds sitting in the nest while the other, as a rule, kept in the vicinity — it was in the middle of April — and I therefore supposed that by this time they had laid the clutch. I therefore shot one of the pair and sent a native up to examine the nest. It did not, how- ever, contain any eggs. At Lake Naiwasha the species occurred quite commonly, and I also observed it here and there on the journey to Elgon. At Eldoret and Soy, for instance, I sometimes saw 3 or 4 together and I procured a young bird a few days' march from Londiani, in the direction of Eldoret. According to Congreve (Journ. East Afr. and Ug. N. H. Soc, vol. Ill No. 6, 1813, p. 45) "one of the common sights of B. E.

Irides are dirty-white, culmen the same colour as in adultus, i. e. black with a bluish base and yellow cere, legs yellow. The dress is very nearly in agreement with that described by Reichenow. However, nearly all the wing coverts are furnish- ed with rusty-brown tips. Reichenow says that the wing- feathers of the young bird are the same colour and design as those of the old bird, but in this specimen the secondaries are dark-brown with wide, blackish transverse bands, whereas the old bird has them pale lead- grey -(almost greyish white) with narrow b.lack transverse bands. On the eastern slopes of Elgou the bird was common and I frequently saw it sitting in the top of some withered tree for several hours quite motionless. It frequents both the interior and outskirts of the forest and the acacia steppe and I saw it even on the highest summit of Elgon (14,000 feet). Buteo oreophilus Hart, and Neum. — Orn.

One evening when we encamped on the edge of the forest — on our way towards Eldoret — at an altitude of 9,000 feet above sea level I saw in the gloom on the middle branches of a large tree a small buzzard.

I often saw it out on the plain perched high up on an acacia growing in such a position as to give the bird a clear view in all directions. As a rule very viligent, it always took flight with heavy, slow strokes of the wings, before one got within range. On one occasion 1 observed two young birds wheeling in wide circles round a small native village, and when one of them swooped down on the remains of some dead animal — close to a negro hut — I succeeding in shooting it. — 69 — It was in an entirely dark-brown dress.

A single individual stayed for several days around our camp on Elgon and sometimes came right up to the tent to snatch away some animal remains lying there. It is very likely that this specimen, which had strayed as far as Elgon, is in all probability a casual visitor from the country to the north, around the Nile and other waters. Comparing the measurement figures of this bird with those of the Mombasa specimens (following bird) we find that, with the exception of the tarsus, they are all higher. Further, it is light rusty- brown all over the belly, while M. migrans parasitus, on the other hand, is generally very dark-brown-alraost dark grey-brown. Even the colour tone of the head and back is light brown, whereas that of the sub-species is dark grey-brown. Hartert says also (Bull. Brit. Orn. Club, 1913, p. 89— 90j that "the true M. aegyptius ranged southwards, sometimes per- haps in in winter only, to South Arabia and Somaliland.

Very common in Mombasa both down at the coast and in the negro villages and market-places of the town itself. 10 or 12 of them daily hovered about the vessels lying in the Gulf of — 70 — Kilindini and, like the gulls, snapped up everything edible thrown into the water from the ships. All observations of this kite prove that it is extreme- ly daring and audacious, for when I rowed over the gulf to study and procure collections in the palm-groves on the shore opposite Mombasa it occasionally happened that the birds approached to within a few meters of the boat even.

It appeared that the measurements are always lower for South African and Central African specimens, but the dark or the light brown dress is not characteristic for these, for there are nearly as many light individuals as dark ones, shot at about the same time of the year. Grant (Ibis 1915, p. 248) and Banner man (Ibis 1915, p. 231) have separated this sub-species from the true 31. aegyp- tins Gm. because they had found that specimens from Southern Africa are darker and smaller. All my specimens from Mombasa undoubtedly belong to this M. aeg. parasitus, partly on account of the darker colour of the dress, partly on account of the low value of the various measurements. Besides, as they were shot in Mombasa it might be more correct to assume that, unless they were born or had lived all their life in these regions, they had come along the coast from the south. Of course, it is not impossible that they should have come from the north, but the distance they would then have to cover is considerably longer than the former and as the native birds of Africa are not good fliers, their powers of flight not being highly developed by means of migrations and exercise in flying long distances, but are more or less stationary or in any case confined to certain districts, it seems to me much more probable that they should have come from the south. All of them had brown irides, yellow bill andl yellow cere, legs citron-yellow, thus difi'ering from the preceding true M. aegyptius both in colour and measurement. — 71 — Elanus coeruleus coeruleus (Desf.). — Rchw.

From Eldoret in the direction of Elgon the road at first passes through the acacia steppe. Close to the road a little falcon sat perched on a telegraph wire, which on closer in- spection turned out to be the above-mentioned. In the collections of the Zoological Institution at the Uni- versity of Lund there are two specimens from the slopes of the Himalaya and in comparing my specimen with these I found that it was exactly like them. The colour of the whole of the back is considerably paler than in typical T. t. tinnunculus. The head is brown with fine, black shaft lines.

I secured the first specimen of this parrot 3 days' march from Londiani, in the direction of Eldoret, when we camped on the edge of the forest at an altitude of about 8.000 fest above sea-level. On the eastern slopes of Mount Elgon this parrot was very common, and the only member of the family seen there. Every morning shortly after sunrise they came singly or in small flocks from the acacia plains and flew whistling and screaming into the forest on the slopes of the mountain, and regularly every evening they were heard noisily returning to the plains again. Judging from my observations they do not spend the nights in the forests, although at times this would appear to be so, for it happened a few times that just before night-fall I saw one or two pairs resting for a while in some tall tree on the edge of the forest. But they soon took to flight again and con- tinued on their way down to the acacias on the plains. During the day they were seldom seen or heard, but in the early morning — while the dew still remained ~ they were always on the move and the forests resounded with their harsh, whist- ling cries. Then they sat pair and pair or 3 to 4 of them to- gether in the highest tops of the giant Podocarpus trees eating of its fruits. They were not afraid nor did they try to hide themselves, and if the first shot missed they were not frightened away but calmly remained sitting, and on one occasion when I aimed at a pair tenderly sitting close to each other in the top of a tall tree, it troubled them very little, although the twigs all around fell, but they continued undisturbed their "tete-a-tete" until another shot put an end to it for ever. I have come across this parrot as far up as 9.500 feet, that is, as high up as the Podocarpus trees follow the slopes of the mountain, for the chief food of these birds consists of the fruit of this Conifer. All the 9 specimens contained in the collection had nothing but the fruit of this tree in their stomachs. With regard to the measurements of the wing, tarsus etc. and the coloration of the dress there are some small differences. In these specimens the length of the wing varies for cTcf ad. 207—210 mm. „ 99 ad. 192—210 mm, „ 9 juv. 195 mm. total length 280-310 mm. length of tarsus 19—21.5 mm. length of bill from cere 28—31 mm. — 73 — The extent of the red on the forehead varies very much in different individuals. As a rule it does not extend farther back than to a line with the front edge of the eye. Still, this red patch in some of them is considerably larger and sometimes stretches a good bit behind the farther edge of the eye. "Whether this is connected with the age of the birds or not 1 am not in a position to decide. The young bird lacks this red patch on the forehead, wings and the tibia (Reich enow) but has the crown and neck purely green, without any mixture of either brown or cobolt-blue, found in the old birds. Further, the lower wing coverts are not uniform green as in old birds but are furnished with a prominent gold-yellow border, ihen again the feathers of the tail both on the upper and lower surface are brownish red at the tips, inside these, greenish brown a d then the same colour as in the old birds. I have not found any differences in size between male and female, but I have males which in the various measurements are larger than the females and vice-versa.

But Someren says in op. cit. p. 266 "So much variation occurs in these birds that it is almost impossible to correctly place any one specimen unless the locality is given." I agree with Someren that these birds vary very consi- derably and that it is therefore difficult to fix the sub-species, especially if the characters, which should be characteristic for the sub-species in question, are not constant but are probably only individual variations, as in the present case. But I cannot agree that the form always is fixed if the locality is given. Such a procedure may lead to incorrect definitions and conclusions. It should rather be so, that if the characters of the respective forms are constant and good, and each one thus a good geogra- phical sub-species, one might without much difficulty be able to fix them and also, on that account, almost establish from what zoo-geografical province they probably come.

From the eastern slopes of Mount Elgon, about 6.500 — 7.000 feet above sea -level, there are six individuals in the col- lection. I place them all — in spite of small differences, as appears from the following table — under the above — mentioned. Wing, tarsus, length of bill from cere 142 mm. 18 mm. 19 mm. 154 mm. 16 mm. 22 mm. 154 mm. 17 mm. 21 mm. 145 mm. 15 mm. 19 mm. 156 mm. 17 mm. 21 mm. 148 mm. 15.5 mm. 18.5 mm. Three of them have a yellow band on the crown, the fourth, on the other hand, has only some of the feathers of the crown yellow at the tips. A female Specimen has a number of the feathers of the back and the wing -coverts at the tips di- stinctly green, but the others are dark, without any green tinge. If I compare my figures for the length of wing, cfcf 154 — 156 mm. 99 142-148 mm., with Grant's (op. cit. p. 258), which for cf are 149 — 154 mm and for 9 150 mm, they agree very well, and when I compared them with the specimens in the Berlin Museum it was seen that they agreed with the latter in every respect. Among the 6 birds there are two which at first sight could hardly be placed under P. m. saturatus for they most closely agree with the sub-species Foicephalus meyeri naevei, described by G r a n t , the feathers of the upper rump and breast in these birds being distinctly blue, but in other respects they entirely resemble the preceding sub-species. Irides red, legs dark-grey (almost black) bill dark-grey. But after comparing these two specimens with the large series, found at the Berlin Museum, Prof. 0. Neumann, who very kindly examined them closely, and myself came to the con- clusion that they must undoubtedly be placed under F. m, sa- turates. If one tries to place these two with the help of the descriptions of the numerous subspecies the task would be very difficult indieed, but knowing that they were shot in the same locality and at the same time as the others the matter becomes somewhat easier. Thus, it is also evident that the characters "blue or green rump" are not sufficient to warrant the establi- shing of new sub-species continually. No doubt it is the same thing with this parrot as with a number of species of Melittophagus, that is, these characters vary partly with age, and partly also with the different dresses. _ 75 — Foicephahis fusdcapillus (Verr. & Des Murs). — Rchw.

Already at Soy, 35 miles south -east of Elgon, the first specimen of this very beautiful bird was shot. It was found in the topmost- branches of the large trees in the dense forest- vegetation growing on both sides of a little river. This birdmay frequently be seen running along the branches at a great speed, at the same time assisting its movements by flapping its wings rapidly, and then the brilliantly purple- coloured wings glitter from a distance, by means of which it is not difficult to discover, in spite of the secluded and well hidden abode. Sometimes — though less frequently — I have seen it fly, but then only for short distances from one tree to another. Sometimes it stops quite suddenly in the cover of some branch and will then remain quite still for several minutes. Someren has met the bird on the western slopes of Elgon and says (Nov. Zool. 1918, p. 267) that it is rather common there. On East Elgon it is, however, a rare creature and was only observed twice, both times in the depths of the forest. Someren states, further, that in one of the specim ens, which was moulting, the old feathers were purplish blue, but the new ones dark-blue. In one of my specimens, which is also evidently in moult, a number of the feathers of the back — pro- bably the new ones — are quite black at the tips.

Mount Elgon In the large series of skins, which I procured of this "turaco" there are specimens from the forests of Ngong and Kiambu, the forests in the neighbourhood of Nairobi, the regions below Elgon and, a great many, from Elgon and I agree with Someren (Nov. Zool. 1918, p. 267) that there is no difference at all between them. On the eastern slopes of Elgon this was one of the most abundant birds in the forests and was usually met with in the dense brushwood and maze of under -growth, where it knows well how to conceal itself. But 1 often saw it running about in the branches of the tall trees. In males shot in May — July, I have, as a rule, found the testes swollen and developed and grey in colour. On the 10th of July 1 found a nest of this turaco for the first time. It was built in a very thick shrub, in an opening in the forest, about 2 Y2 meters from the ground. It was not close to the trunk but out on the edges of the outermost slender, spiny branches, where the foliage was densest and where it was also hidden by a great wealth of climbers. The nest could only be seen by looking up between the branches from below, for then one could espy in the gloom a very imper- fect nest, which reminded one very strongly of the nest built by Columha palumhus. It was quite flat and consisted exclusively of dry twigs, which lay scattered around without any order and were so few in number that the two eggs could be seen between the materials of the nest. In the literature on the subject it is generally stated that the Musophagidae lay three eggs (R e i c h e n 0 w II. p. 26) and I therefore waited some days to see if there would be another egg before taking the clutch. But the clutch was not increased. Then I took down the nest and eggs in order to study them more closely. The nest measured 36 X 28 cm. and was only a few cm. high (at the highest point, 3 cm.) and so carelessly built that a puff of wind would undoubtedly at first have blown the eggs off. When I found this nest the female was sitting on the already slightly incubated two eggs, but whether the nest contained 3 eggs and one had been lost, is difficult to say. Later one I found another nest of this bird containing two nestlings. — ?7 - The eggs had the following measurements and weight: 1. 38.2 X 30.9 mm. 1.07 gr. 2. 40.7 X 31 mm. 1.21 gr. In form they are slightly ventricous and blunted at both ends, thus closely corresponding to the ovate type. The shell is hard and thick and not as, for instance, in dove-eggs, — which they resemble very much — dimply and granulous but smooth and dull without any gloss. In colour they are white. In the stomachs of some individuals I found only fruits and bits of plants, in others the remains of grasshoppers and various insects. This turaco occurs as high up as 11,000 feet and is thus found beyond the forest. I have even observed it on various occasions in the bamboo-woods.

In the forests at Kiambu (near Nairobi) I saw this Cuckoo a few times. It kept, as a rule, to the edge of the forest, where the dense brushwood grows. The specimen I procured is light-brown or ochraceous on the whole of the under-surface, which colour, however, can easily be washed away with a damp piece of cotton. Thus it is only a staining caused by the reddish-brown laterite of the ground, which has caused this colour. This specimen ditfers from others in the Berlin Museum collection, with which I have compared it. The back of this individual is not uniformly chestnut-brown but almost of the same colour as Centropus (monachus) fischeri Rchw., that is, blackish brown. And yet it is undoubtedly near C. m. monachus^). 1) Perhaps my bird is an unnamed new form of C. monachus, but according to Grant (Ibis, 1915, p. 421) the true C. m. monachus occurs southwards to Kikuyu. — But it resembles the Central Abyssinia form (described by Neumann: Bull. Brit. Orn. Club, vol. XXI, p. 77) — 78 — But I have observed in C. s. superciliosus, C. s. senegalensis, Anomalospiza imherhis Q and other birds, in which brown enters into the colour of the plumage, that this brown colour at the period of moulting or' during moult — owing to the wear and long use of the dress — is considerably darker than in the fresh dress, exactly as in the case of the green plumage of a number of species of Melittophagus, which changes into a more or less cobalt-blue. This individual is in the beginning of the moult, and that is why the colour of the back is different from that of specimens in fresh plumage. Wing 205 mm. Tarsus 49 mm. Irides blood-red, bill and legs black. 1 venture to point out here that if this subject of colour- changing of the dress was paid more attention to by a number of systematisers, and birds of certain families from one district only were compared with others from other districts in the same stage of plumage, many birds now described as doubtful would probably not have been advanced as new species or sub- species. Centropus senegalensis incertus Granvik. 1 (5 6. 4. Mount Elgon. Immediatly below the eastern slopes of Elgon, in the acacia- country, I saw two specimens of this Cuckoo and as I wandered about in the tall grass I was fortunate enough to find the pair's nest. I hid in the vicinity and then noticed that one of the birds flew into the nest and sat on the eggs. After a while I flushed this bird and shot it. It then turned out to be the male. Total length in flesh wing tarsus bill tail 370 mm. 165 mm. 42 mm. 30 mm. 200 mm. Colour of irides, red; bill black; legs dark-grey; Grant (Ibis 1915, p. 423) says "middle claw white", but in this specimen all the claws are black. At the Berlin Museum I examined 35 spec, of Centropus senegalensis senegalensis from different parts of Africa, shot at different periods of the year. All of them have a green wash on the head and a still deeper one on the rectrices. In this respect the Elgon form differs from all of them, because it is entirely devoid of this wash both on the head and tail, but is dull and soot-coloured instead. Hence it cannot be classed among this sub-species, even if the respective measurements agree. It reminds one somewhat of C. senegalensis ischadensis of Reichenow (Journ. f. Orn. 1915, p. 124) but the latter has occidentalis in the coloration, and as it seems to me, that the latter is a good form (Grant, op. cit., makes it synonymous with monachus) my bird might by termed as above. — 79 — the typical wash on the head, which mine lacks. I have com- pared mine with the type-specimen in Berlin. In the colours of the dress it agrees entirely with Centropus s. aegyptius Gm. inasmuch as "the mantle and inner secondaries are olive-brown and the flight feathers chestnut". Grant says, however, (op. cit. p. 123) that this form is much larger than C. s. senegalensis, which my measurements though do not prove. A specimen found in the Berlin Museum from Fuah (Egypt) has a wing-length of 165 mm., tail 225 mm. Another (9 juv.) has a wing-length of 155 mm., tail 205 mm. Both are, however, considerably darker than the Elgon specimen. Grant says, further, that the distribution of C. s. senega- lensis ranges from Senegal to the mouth of the Congo River, eastwards across the Niger, upper Nile, upper Congo and Uganda to Somaliland, but that C. s. aegyptius occurs only in Egypt. The discovery of the bird on Elgon thus establishes that the dis- tribution of the bird towards the east ranges into British Eeast Africa. According to Chubb., senegalensis was found by him in South Rhodesia (Ibis 1909, p. 141, 153) but already in 1874 the bird was kown from Bamangvato, Bechuanaland. My specimen is in moult and the feathers are much worn (which is in itself noteworthy as the bird has already began to brood) and it is therefore probable that when the new feathers had grown to their full lenght, the measurement of the wing would have been greater. Reichenow, who has also examined my specimen, is of the same opinion as myself that it cannot be referred to any of the forms of senegalensis at present known, and therefore owing to the most striking differences — although only one specimen was procured — I have given this bird a new name. It is possible that further specimens from these districts will show that this new form is a synonym of some of those already described and that mine is thus only an aberrant. P'or the present at any rate, I shall name it C. senegalensis incertus. The nest was built in a dry, little acacia shrub, growing almost concealed in the grass, more than a man's height, and was situated 30 cm. above the ground in the fork of the two largest thorny branches of the shrub. It was 45 cm. high by 26 cm. wide and oblong in shape, provided with a roof and side entrance. The nest-materials were composed only of long blades of grass, both fresh and dry, which were plaited together into an extremely loose and weak structure, the walls of which were so thin that one could see through them. The bottom of the nest itself was, however, stronger and about 5 — 6 cm. thick and lined with the fresh, thick leaves of a bush common on the steppe. — 80 — There were four newly laid eggs in the nest. 1. 30.5 X 26 mm. 775 mg. 2. 32.5 X 26.4 mm. 780 mg. 3. 31.7 X 26.8 mm. 775 mg. 4. 30 X 24 mm. 675 mg. The eggs are bright white in colour. Two of them, however, have large and small brownish red spots here and there, but these spots are caused by the brown laterite clay which the sitting bird has had on its feathers. No doubt these brown- spotted eggs are the ones first laid, as those laid later are quite white. When I blew out the eggs I found — at least quite plainly in one of them — that they were in different stages of incubation, for in the more heavily spotted egg the embryo was much more developed than in the others. It is therefore probable that incubation begins as soon as the first egg is laid. The shell is dull and smooth without any marked pores and furnished with a layer of lime, which can be scraped off. In this layer there are ripples and scratches. This bird is very shy and viligent and knows very well how to hide itself on the ground in the tall grass. I seldom saw it perch on any of the rare bushes, and it happened a few times while I was studying the nest at a distance that the bird quite suddenly be sitting in the nest without my having noticed when or how it got there. When it was flushed it usually disap- peared in the grass and would then rise some hundred yards from the spot where it disappeared. The stomach was full of hairy, large, green larvae and grasshoppers. Ceniropus superciliosus superciliosus Hempr. & Ehr. — Rchw. II. p. 65.

When we look at this series of 10 skins from difi'erent parts of East Africa — right from Mombasa up to Victoria Nyanza — we at once notice the great differences they present. The specimens from the coast and from the Nairobi regions agree entirely with each other in the markings, although the respective mesurements for the tarsns and wing vary somewhat. On the other hand the two from Kendu (Victoria Nyanza) are difi'erent from all the others in that the head, nape and inter- scapular region are considerably darker in the latter. These parts are almost blackish brown. This is true of the young bird as — 81 - well as of the old. Whether this character is sufficient to name a special local form of the C. superciliosus living at Victoria Nyanza I am not able to decide at present. Grant has (Bull. Brit. Orn. Club, vol. XXXV, 1914, p. 54) described a new form of C. superciliosus, named C. s. loandae, and judging from the description the Rendu specimen should, I suppose, belong to this race. Not having seen any specimens belonging to this formv however I dare not exp ressany positive opinion on the matter. According to Grant the distribution of this form is from Angola to the north of Congo River, eastwards to eastern Bel- gian Congo and north-eastern Rhodesia. But the same writer also points out that intermediate specimens of this race and C. s. superciliosus are found in German East Africa, British East Africa and in Uganda- and therefore the Kendu birds may be such intermediates. The newly described C. s. intermedius by v. Someren (Bull. Brit. Orn. Club, vol. XLI, 1921, p. 125) which „differs from the typical South-Arabian bird in being darker above and smaller. Wings 140—155 mm" can scarcely be considered as a good form, but is, I dare say, only a subtile form between superciliosus and loandae (vide Grant). Among the Kikuyu spe- cimens some are fairly light above and others darker and the variations in the measurements of the length of the wing can be seen in the table below. V. Someren does not give the distribution of inter- medius (terra typica: Mombasa) but if the author considers this new form only as a new coastal bird, it is possible that the description agrees with respect to the wing- measurement. My specimen from Mombasa belongs to the light forms, but in spite of the fact that the wing-measurement falls within the 140 — 155 mm given by v. Someren I cannot support his new form, which is probably nothing but a casual individual variation. In C. €. superciliosus the wing is 140 — 150 mm. The two most interesting individuals were shot in the en- virons of Nairobi. They are a beautiful brownish -red all over the under-surface of the body; the head and interscapular region being of the same colour. But this beautiful colour disappears at once if a damp piece of cotton -wool is drawn across the leathers, and is thus only a superficial wash caused by the discoloration of the ground. In the young bird the rectrices are more glossy green than in old birds and tapering at the tips (in the old they are rounded) and are furnished with 3—4 narrow, white transverse bands. The young bird from Kendu (Victoria Nyanza) is also unlike the one from the Nairobi regions in that the feathers of the back and sides of the neck, in addition to the rusty-brown streak nearest the shaft, have a triangular yellowish-brown spot 6 — 82 - on the tips and a larger one of the same colour higher up. The upper mandible is dark -grey, the lower mandible for the most part yellowish browu. Irides yellowish-brown.

It agrees in every respect with the 3 specimens of this bird found in Berlin. E r 1 a n g e r (J. f. 0. 1905, p. 464) and Z e d 1 i t z (J. f. 0. 1915, p. 11 — 14) have established that of the little Honey Guides we have two "form-circles": minor and exilis, and that those found in East and North East Africa (of both groups) are a uniform olive-green on the under -parts while the West African have blackish brown longitudinal streaks on an olive green ground. Bannerman (Ibis 1921, p. 84) gives the wing -length for d'cf 88—92 mm. for 99 79, 85, 85 mm. My specimen belongs to the last-mentioned group and is thus a representative for the West African birds, found in East Africa. According to Reichenow (op. cit.) the bird is met with in the Gold-coast and its distribution is fixed, by Zedlitz (op. cit.) to lower Guinea, by Grant (Ibis 1915, p. 434) to Gaboon north of Ogowe River and Cameroon, by Erlanger (op. cit.) to West Africa piercing eastwards to Albert and Albert Edward Lakes. As v. S o m e r e n (Journ. E Afr. Ug. N. H. Soc, 1921 No. 16 p. 32) says that he is not satisfied with the identi- fication of his specimens of 1, minor teitensis from Moroto, W. Lake Rudolph, and gives 93 mm. as the wing-length of one specimen, which judging from the brief description and the mea- surement of the wing, is propably not a teitensis at all. I am inclined to believe that even his birds are possibly specimens of conirostris. In proportion as different discoveries determine that species hitherto considered to be solely westafrican also occur in East Africa the problems of their distribution must to some extent - 86 - be changed, and every student who has dealt with the Indicator family, as a rule, arrives at the same conclusion that our present knowledge of these birds is still rather confused. It seems to me to be rather doubtful wether we can maintain 1. m. riggenbachi Z e d 1 i t z as a good sub-species and when com- pared with I. m. conirosiris the difference between the two appears extremely slight (and only the sexual difference) and its geographical presence does not by any means speak for its further existence. Further discoveries must, however, bring light on this point. Capitonidae. ^ Lyhius hidentatus aequatorialis (Shell). — Uchw. II. p. 119. 3 (5(5 ad. 14. 5.; 1 Q juv. 14. 5. Soy 7,500 feet. - 1 Q juv. 26. 5. Mount Elgon 7000 feet. Some miles north-east of Soy on the way to Elgon we halted in the acacia-country by a shallow little lake, and in the low trees growing on its shores this bird was a common occurrence. Only once was this Barbet observed on the eastern slopes of Mount Elgon. The five specimens exhibit the following measurements: wing, tarsus, 106 mm, 25 mm. 105 mm. 26 mm. 107 mm. 26 mm. 103 mm. 25.5 mm. 104 mm. 25 mm. In the three mature cTcf the upper surface has a dark-blue metallic lustre, the bill is whitish yellow, irides are dark-brown. The plates on the front and back of the tarsus are dark horn- brown, while the middle part, i. e. the sides, is yellowish white. The young birds have the upper surface black with a more or less blue wash and one of them has the crown furnished with numerous red feathers like a full-dressed adult. The white spot always found in the middle of the back is greenish in one of the specimens, the feathers forming this spot having a light-green border both on the edges and the tips. The bill of the young birds is whitish-yellow with a reddish grey wash. Irides and legs of the same colour as in the old bird. Lyhius melanopterus melanopterus Ptrs. — Rchw. II. p. 121. 2 ^(5 29. 4.

But on an open field close to the native village there stood a tall expansive, dense tree in which 4 or 5 of these birds regularly took their meal of fruits in the mornings. The birds were slow and not very shy, and when one of them was shot the other birds did not fly away but con- tinued their meal undisturbed. Their cry is a shrill screech which can be heard at a long distance. Wing, tarsus, culmen, tail, 92—98 mm. 25—26 mm. 27—29 mm. 60—63 mm. Two of the specimens have two teeth on the left side of the bill, but only one on the right side. The other three have two teeth on either side, the front one being the more powerful. The females are somewhat lighter on the back than the males, but in other respects there is no differences between the sexes. Irides dark brown; bill and legs black. Lyhius senex (Rchw.). — Rchw.

I have never seen this species in the interior of the forests but always on the outskirts, where they are bounded by the open field. On one occasion when I observed the bird, it frequented the small, scraggy trees growing on the banks of a little brook running past a large garden. But on another occasion it was flying about in a field of maize. Wing, tarsus, culmen, tail, 96 mm. 26 mm. 27 mm. 57 mm. cf ad. 95 mm. 24 mm. 27 mm. 52 mm. cT juv.

Further, — 88 - the young one is uot blackish brown on the lower back, like the adult, but predominantly white with a few brownish feathers here and there. Undoubtedly the plate given by Lonnberg in his work (Birds coll. by the Swed. Zool. Exp., to B. E. A., 1911) is a picture of a young bird changing to the full dress, because in my example the white band on the shoulder extends right across and blends, without any noticeable termination, into the lower white part of the back. As the bird gets older this band gra- dually disappears, and in the full grown — in full dress — there is no trace of this band at all. Irides brown; bill and logs black. Lyhius torquatus irroratus (Cab.). — Rchw. II. p. 26, 2 S6 ad. 27. 4., 29. 4. Mombasa. Occurred in the thinly wooded coastal regions at Mombasa. Id the evenings it sat perched on the outermost tips of the branches of the small trees, making the wood resound with its shrill cries. Perhaps the greyish green colour of the legs is a juvenile character. Both individuals had not yet completely assumed the uniform red colour, on the crown and throat of the full-grown bird; it being less completedly marked, and in one of thee spe- cimens this red patch extends down into the middle of the black setting of the fore-neck.

In the dense, almost impenetrable, brush-wood, which here and there borders the shores of Lake Naiwasha a pair of these birds was found together.

Mount Elgon. In certain places on the eastern slopes of Mount Elgon this bird was met with in fair numbers. It generally frequented the heart of the forests and was almost always seen high up in the branches of the dry trees. It runs up the trunks of the trees with great alacrity and skill — like the woodpecker — con- tinually turning and "jerking" its head and pecking into the decayed tree-trunks and branches, thereby producing a sound similar to the drumraings of the woodpecker. It flies swiftly and well and descends in long curves bet- ween the short, few strokes of the wings. They are met with always singly or in pairs and at times are only seen with diffi- culty, owing to their darkbrown coloration unless, the loud blows of their bills against the trees proclaim and betray their where- abouts. In the stomachs of the 9 individuals examined I found remains of insects and stone-fruits. — I have seen the bird up to an altitude of 8.500 feet.

In one or two there are a few brown streaks on the upper mandible, and the lower mandible is considerably lighter at the base than at the tip. The old bird has the nasal tufts yellowish brown and the forehead yellow -speckled, but the tuft of the young bird is dark-brown and black at the tips. Besides, it has not the straw- coloured feathers on the forehead. The laack is uniform dark- brown and not as in the adult, where the feathers of the back and part of the shoulders have a white streak along the shaft. The underparts are dark earth-brown and the light edges are not very conspicuous. The tail is usually brownish black. Still, there are in my series two specimens having a dark olive-green gloss and rusty brown tips. These two have, besides, both the outer-web of the wing-feathers and all the feathers of the underparts olive-green at the tips. — 90 - This is the newly assumed plumage. When it has been in use for a time and begins to abrade the olive-green colour on the wings, the tail and the under surface fades, the feathers of the underparts being tipped with brownish white. When the dress has been in longer use the light tips, as a rule, get worn off and the underparts become more uniformly dark-brown. Barhatula simplex leucomystax Sharpe. — Rchw. II. p. 146.

This little Barbet was quite common on the eastern slopes of Elgon, where I saw it in small flocks of 4 or 5 in number in the open spots, overgrown with bushes and low trees. It was seen in the company of B. hilineata and therefore my skinner believed and assured me with certainty that it was only "mtoto", the young, of that bird. Wing 52, 54, 54 mm. Tarsus 15 mm.

The two individuals, which I procured from Elgon, should, it seems to me, be placed under this subspecies. They were both in full dress and the one shot on tbe 23. 5. also had large and swollen testes. In respect to the colours of the plumage they are good B. hilineata^ the chin being white and the fore-neck light-grey. The yellowish green edges on the wing- coverts and wing feathers run more into green. When compared with type-specimens from Kaffraria (in the Berlin Museum) a very slight difference can be discerned between tbe East African specimens and the South African, the former being more sulphur-yellow, the latter more golden yellow on the outer web of the wings. My birds put one in mind of B. kandti Rchw. (Orn. Monatsber., 1903, p. 23) but as this species is probably not a good one but only a synonym of B. jacksoni (which even Reich enow himself is inclined to think J. f. 0., 1918, p. 70) in fixing these Barhatula races I have followed Neumann's revision (J. f. 0., 1907, p. 345—346) and later on compared the races with the specimens in the Berlin Museum. The conclusions I then came to are different from Neumann's (op. cit.). - 91 — B. h. Ulineata has the chin and throat white, B. h. jack- soni Sharpe, on the contrary, greyish white. The edges of the wing-coverts and wing-feathers are not always a darker sulphur yellow in B. b. hilineata than in B. b. jacksoni but frequently vice versa. My specimens of the former have considerably paler sulphur-yellow edges than the latter. The richer or paler sulphur- yellow colour on the edges of the wing-coverts and wing feathers varies with the seasons and does not seem to me to be a deci- sive character of any systematic value. Reichenow (Orn. Monatsber., 1915, p. 91) has further described another form from Tanganika, which is said to be very similar to Jcandti but has the rump lighter citron-yellow: urungensis.

It is grey on the throat and the grey colour of the fore-neck is darker than in B. h. bilineata.

Wing, tarsus, culmen, tail, 54 mm. 16 mm. 14 mm. 32 mm. The measurements, on the whole, agree with those of the preceding, and therefore they cannot thus be a conclusive factor in fixing these two birds. Fogoniulus pusillus affinis Rchw. — Rchw.

Of the four mature specimens — all in full plumage — 3 agree with the current description and Grant's supplement (Ibis: 1915, p. 102). One individual, however, differs rather much as regards the colour of the under tail-coverts, for, in general, this is light rusty yellowish brown, but in this individual the tail-coverts are dark-brown, nearly of the same colour as the throat. Irides are usually brownish red. Yet, in two specimens I have found a yellow ring outermost with an inner one of brown. Bill dark greyish brown. Legs yellowish brown — greyish green. The young bird is darker on the side of the back, and some of the feathers, which become greyish brown later on, are furnished with greyish white transverse bands. The rusty-brown colour of the neck is also paler. The sides of the throat, which in the old bird are black and white banded, are banded with brown and black. The under surface is white with black longi- tudinal streaks.

Of this bird, very common everywhere, I have in all 34 skins, from the coast right up to Victoria Nyanza and Mount Elgon. Were I to divide these after the localities and give the sub-special names which van Someren (Bull. Brit. Orn. CI. Dec. 1919, p. 26—27) has given them, I should have 6 C. s. mombassicus, 14 C. s. kikuyensis and 14 C. s. ugandensis. However by carefully comparing my own specimens with those found in Berlin Museum and in the Natural History Museum at Stockholm, I have not been able to find the slightest difference between C. s. kikuyuensis and C. s. ugandensis. As a difference between these two Someren mentions, among other things, that the latter resembles the former but has "crown and mantle lighter above" and the "wings and tail greyish olive" while in C. s. kikuyuensis they are "deep greyish olive". The other characters, which should account for the existence of these two sub-species, seem to me to be very weak and by no means characteristic for birds from the localities given. As regards the character given for C. s. ugandensis i. e. "lighter above" than C. s. kikuyuensis, this does not agree at all with my Elgon and Victoria Nyanza specimens, for a 1 1 of them are considerably darker than C. s. kikuyuensis. On the other hand there is a more distinct difference be- tween C. s. mombassicus and all those from Kikuyuland and farther east and north, and I can therefore only establish two forms: one coastal form and one from the interior parts of the country. The former I name C. s. mombassicus v. Som. while C. s. ugandensis may stand for the latter. It might as well perhaps have retained the third name, but as I consider this only an intermediate form between the two given above 1 exclude it altogether.

At Kiambu, near Nairobi, this bird was rather common in the dense forests. Only one of the three males shot there is in full dress. The other two still have some of the red feathers of the belly tipped with grey. The three males from Kiambu are all in different dresses and show a very beautiful transition to the full dress. In the youngest the lesser wing-coverts are blackish with a pale green gloss, bordered with a bronze green seam, the median wing- coverts are of the same colour but have in the posterior half small, indistinct brown dots, the greater wing- coverts are dark vyrithout any green seam but have numerous small, fine brownish grey or brown spots. In the next stage the lesser wing-coverts are as in the preceding but on the median the green edge has disappeared, the spots being larger and arranged in indistinct undulating lines, the spots on the greater wing-coverts whitish, larger and also in undulating lines. In the adult bird the spots on the median and greater wing-coverts are white, forming dis- tinct undulating lines, the lesser wing-coverts as in the preceding. In one of the young birds (cT) some of the undertail-coverts are white, the others red. — 97 — Irides brownish red, — dark brown, bill yellowish green, and the base yellow; legs yellowish brown — dirty lilac -cou- loured. wing, tarsus, culmen, 128, 134, 136 mm. 16-17 mm. 19 mm.

Soy. - 1 ^ ad. 6. 6. Mount Elgon. — 1 e ad. 15. 5.; 1 Q juv. 16. 5. Soy. On the way up towards Elgon — a day's march from Soy — I came upon a little flock of this Roller out on the acacia-plains. In the late hours of the day they flew screaming from tree to tree — about 10 in number — and always perched on the highest, dry branches of the acacias, where they could only be seen with difficulty. They were not afraid, but would let one get very near them before taking flight. Excluding the young bird, whose plumage considerably differs from that of the old birds, the other three from the Soy district exhibit rather great differences in regard to the colours of the rectrices and upper tail -coverts. And yet they are shot out of one and the same flock, whence it must be considered very likely that, in spite of the differences, they belong to the same form. One of them has the two middle rectrices a uniform brown and the two median tail-coverts brown, which later character is, as a matter of fact, found in all. Another has a distinct light blue tinge in the form of a narrow band along both sides of the shafts of the middle rectrices. A third has a broad dark-blue tinge at the base and along the shaft of the middle rectrices, and in the Elgon specimen this blue field stands out more prominently. Whether any one of these is to be referred to E. afer aethio- picus is difficult to decide. The different measurements, however, do not agree with those given byReichenow (Vogel Afrikas II. p. 231) but rather with those of Neumann (Journ. f. Orn. 1905, p. 185) for the above mentioned form, where, e. g. the wing-length amounts to 179—190 ram. 7 — 98 - wing, tarsus, culmen, 190 mm. 20 mm. 28 mm. cf Soy. 185 mm. 20 mm. 29 mm. d Soy. 185 mm. 19 mm. 29 ram 9 Soy. 185 mm. 19 mm. 30 mm. cT Elgon. 175 mm. 20 mm. 28 mm. cf juv.

This interesting hornbill was found in fairly large numbers on the eastern slopes of Elgon, from an altitude of 6 800 ft. up to 8.500 ft. During the day small flocks of from 4 to 6 in number were continually seen flying across the tree-tops of the forests with heavy, rumbling strokes of the wings, incessantly uttering their shrill, dull, hollow cry, "go-ork, goork". Very seld- om was I able to get within range, for they are among the most viligant and cautious birds of the forest, which, as soon as they have a presentiment of anything suspicious, at once get to a place of safety. Whenever they were seen at rest they sat out of range on the top -most branches of the tallest giants of the forest. But early one morning I stood concealed at the foot of a forest tree waiting for monkeys, when all of a sudden three of these large hornbills perched in my vicinity. Within a short while others came and perched on the branches of the trees close by and after a few minutes another flock arrived. At last some twenty had gathered and now began such a clamour and noise as can scarcely be described. Above me were two, screa- ming their hoarse cries, and from all directions the forest resounded with their dift'erent voices. The whole thing gave one the impression of a "gossip" meeting, where each one endeavoured to drown his neighbours voice. What such a morning meeting really means is difficult to decide, Later on, I had the pleasure of being present at these — 99 — meetings twice and they were always conducted in the same manner. Always the birds sat perched, well hidden on one of the middle branches close to the trunk of the tree or in the shelter of the dense foliage. And when they let their cries resound through the forest, they stretched out their heads so that the neck formed an obtuse -angle to the longitudinal axis of the body. They would, thus keep up their morning concerts for hours, after which they dispersed in various directions above the immense forest. Cab an is mentions (Journ. f. Orn. 1880, p. 351) that the negroes had informed him that the male walls up the nest, leaving only a little opening, and that the female must stay in this prison until the young are a few days old. But the author does not mention whether the nest is built in a hollow tree- trunk or in any other sort of cavity. Reich enow (Vogel Afrikas II. p. 233) says, on the other hand, that the hornbills choose a hollow tree for their nesting- place and this is probably the case with the majority of the Bucerotidae. — van Someren (Ibis 1916, p. 223) says "We have seen their nesting- holes on several occasions, but have not taken the eggs". But the writer does not state where and how these "nesting -holes" were situated. Probably they were in trees, for otherwise the author would have called attention to the irregularity, if such had been present. During my stay on Elgon I asked the natives to look for a nest of Bycanistes subcylmdricus and I was convinced before hand that it should be sought for among the trees of the forest, and therefore 1 commanded them to look in the forests. One day one of the natives informed me that he had found such a nest, not in the forest but among stones. Little thinking that it was a hornbill's nest I nevertheless followed the native up towards the heights of Elgon. Below Endebess — at about 8.000 ft. — on the eastern slopes, where large boulders and stones had been blown up and lay scattered everywhere, he pointed between two large blocks, saying that the nest was there. 1 had promised the negro 5 rupees if the nest contained eggs and to convince himself on this matter, he had, on finding the nest pulled down the greatest part of the wall which cut off the space between the blocks from the outside. Still, the lower part was left and proved to be very strong, in some places even as much as 2 cm. in thickness. In the nest, when the negro had examined it the day be- fore, there was only one young bird, which according to his statements should still be in the neighbourhood. I shot in this spot a rather well developed young bird, but whether it was the one that had inhabited the nest is doubtful. On the floor of the nesting-hole lay many blackish-white feathers, which undoubtedly belonged to the female that had once inhabited his dwelling. — 100 — To try to establish, on the basis of the discovery of o n e nest, what is the rule or the exception is certainly difficult. Whether the nesting -place of this species was in the present case only a deviation from the usual method or not, is difficult to judge. The natives, 1 know, assert that this bird always builds its nest among the stones — at least on Elgon — but whether this is true or not later discoveries must decide. C a b a n i s mentions further (op. cit.) that the contents of the stomach consisted of berries which looked like beans. In the five individuals I brought home (and in two more which were destroyed) 1 have found large, hairy insects, grit and stones but only in one of them small, hard fruits, wing, total length, tarsus, tail, culmeu, casque, 360 mm. 740 mm. 52 mm. 290 mm. 168 mm. 105 mm. cTad. 375 mm. 790 mm. 58 mm. 305 mm. 190 mm. 135mm. 9ad. Irides brown; bill blackish; the front one-third of the cas- que black, the rest yellowish. Legs black.

The colour of the rest of the bill was dark plumbeous. The feathers of the head, which even in fuligrown young (and the old) are edged with grey at the tips, are in this case en- tirely rusty- brown with a black streak, widening towards the tips along the shaft. The feathers of the throat are grey, some with a pale brown wash. In other respects it resembles the full-grown birds, but the lower surface has not yet acquired such a pronounced dark metallic green gloss. Irides are greyish brown. Legs black. But neither in this young bird nor in the other two are the two middle rectrices tipped with white but are in all three of them entirely black with a metallic gloss. The two other birds have the following measurements: wing, total length, tarsus, tail, culmen, casque, 325 mm. 685 mm. 48 mm. 290 mm. 140 mm. 28 mm. 9 juv. 320 mm. 690 mm. 48 mm. 280 mm. 142 mm. 30 mm. 9 juv. In the colorations of the plumage they are exactly similar to the full-grown, but their bill has quite another appea- rance, in that the posterior end of the casque, which besides being now black, has began to develop. The upper ridge of the culmen is in these two wavy and rough and the bill is furnished with dimpled depressions and ridges. Sclater's plate (Proc. Zool. Soc. London 1871, p. 490) of the head of this species shows the bill, with the elevated — 101 — casque, of a nearly full-grown bird. It marks a transition stage between ray picture (a somewhat younger individual) and the full-grown. Fig. 2. The development of the casque of Bycanistes subcylindricus Scl. Foto : H. Graiivik. 1.

Not less than 6 birds have 50 mm and upwards. Only six specimens are in full dress; all the others are in moult. In one individual it appears that the new tail-feathers are dark-blue without any purple gloss; in another they have only such a gloss at the base, and in those in full plumage they are almost to the whole of their length purple-glossy (at least the central tail-feathers). The young bird's bill is not such a beautiful coral-red as that of the old birds, but has a more or less deep tint of grey. It is, however, not black as in Rhinoponiastus erythrorhynchus. V. Someren says (op. cit.) that "they have the feathers of the rump broadly tipped with coppery bronze". But all the specimens in my series have these feathers blue without a cop- pery bronze. 1 cannot agree with v. Someren' s opinion that the white on the throat is purer, for all mine have a plain brownish yellow wash over the white. In all the specimens the irides were dark-brown (Grant, brown; R e i c h e n o w orange), bill coral-red, legs coral-red with black claws. Whether the Elgon-bird, however, forms a special race which differs to size from • the true I. b. jacksoni, should be difficult to decide at present. It seems to me to be so and later in- vestigations may perhaps bring light on the matter. Ehinopomastus cyanomelas schalowi Neum, — Journ. f. Ornithol., 1900, p. 221. 1 (5 ad. 29. 4.

One of the females has the crown and hind neck a beau- tiful steel-blue gloss, the others are blackish brown. In the specimens from Mombasa there are great differences with regard to the white parts of the tail-feathers. One 9 bas, for instance, five of the tailfeathers broadly tipped with white, which on the inner-web extends much higher up than on the outer-web. (Fig. 1.) Another lacks this white entirely. A third has only a little white spot on the outer-web of the two central rectrices. (Fig. 2.) Two cTcT have a white patch close to the ti.p (Fig. 3.) The head and neck of the young birds are yellowish brown as a rule, and the white on the tail-feathers is small or missing altogether. Irides dark-brown; bill and legs black. On Elgon this race was not nearly so common as 1. h. jaJcsoni, and it was found as a rule only on the outskirts of the forests or where there were thickets and brushwood. Caprimulgidae.

This race was common in the acacia-country, below the slopes of Elgon, especially where the ground was covered with large and small boulders. The specimen is in full plumage. Grant has (Ibis, 1915, p. 303— 305) separated 5 forms of natalensis and of these there cannot, in the present case, be any question of any other than chadensis. In the original description it is stated that this form "is of a pale sandy-brown colour", but my specimen is more rufous both on the upper and the lower parts and may perhaps in colour approach fulviventris from Angola. Mr. J. Chap in, New York, has shown me a specimen shot by him in the vicinity of Lake Chad, which agreed in colour with Alexander's description. Wing 150 mm; tarsus 20 mm.; tail 107 mm.

Here and there the commenced excavations for their future dwellings were seen. It is possible that the holes in the sandbank, leading into the narrow passages are not dug by these swallows, for I never saw them engaged in the work of digging although they flew backwards and forwards in front of them and at times sat resting in the mouths of the passages. Wing 98 mm, tarsus 10 mm. Irides dark-brown; bill dark- brown (brownish black); legs black. In the Royal Natural History Museum in Stockholm there are specimens of R. p. minor from Kilimandjaro which are lighter and paler than ducis, but according toSclater & M.-Pread (Ibis 1918, p. 715) minor occurs in Abyssinia and the upper Blue Nile. The question is then, whether the individuals esta- blished by S j 0 s t e d t are really minor and that the distribution of that race thus enters the region for ducis (which is hardly probable) or are only paler specimens of ducis.

In Londiani this swallow was abundant and was breeding in a railway bank in the forests. At Soy, where the race was also common, I saw them in the evenings flying in flocks around some small pools of water in the grass-plains. In July the young — 118 — birds were full-grown and the specimens I procured were all birds of the year. I have seen the race in all sorts of localities, but always in small or large flocks. It seems, however, to be a highland bird, and in the acacia-country below the slopes of Elgon it occurred practically speaking everywhere. The wing-measurement in the adult birds is 120 — 135 mm., tarsus 12 — 15mm.; intheyoung 122- 126mm., tarsus 12— 13mm.— Irides dark-brown; bill and legs black.

This swallow was breeding very commonly in the giant caves on the eastern slopes of Elgon. Frequently the nests were only Vs — 1 metre from the ground and usually in the outer parts of the caves. Sometimes they were found high up on the steep walls and rather far in the interior of the dark parts, where the bats lived in countless numbers. The nests were comparatively small and lined with feathers and hair. The eggs — generally three in number — were in shape and colour like those of H. rustica, but somewhat smaller in size. Owing to a mishap the eggs I procured were crushed and the nests destroyed, and I am therefore unable to give any further particulars. As Reichenow points out (op. cit.) Sharpe separates Uganda specimens, which he calls H. arcticincta (terra typica: Elgon) from true H. angolensis Boc. The former should have the centre of the underparts of the body white, the latter, greyish brown. — 119 — One of these two specimens has the centre of the lower sur- face whitish, the other distinctly greyish-brown, and yet they were shot on the same day and on the same spot. It is there- fore probable that this dissimilarity is due to the difference in age, which appears from the fact that the whitish one is a young bird. I think that Reichenow is justified in doubting the genuineness of these two races, and I therefore give B o c a g e ' s name for the Elgon form. Wing 120, 121 mm., tarsus 11 mm.

This race was common in the Nairobi regions and in Mom- basa. Both specimens are in full plumage and have the chin of the same reddish brown colour as the head. The steel-blue lustre on the wings and tail-feathers is very pronounced. Reichenow (Jouru. f. Orn., 1921, p. 265) expresses the opinion that the three forms of puella cannot be maintained, as, in his opinion, the characters which distinguish them are not constant. I have compared the specimens in Stockholm, which L o n n - berg brought home from Nairobi, and found that the striping varies very considerably, and in 3 of the specimens it is finer, in others coarser. It is the same thing in these two specimens of mine. Wing d" no mm., 9 105 mm., tarsus 13 mm. Irides dark-brown; bill black; legs dark-brown. Eirundo senegalensis senegalensis L. — Rchw. II. p. 415.

I met this race for the first time when we camped at an altitude of 8.500 feet a few days' march north-west of Londiani on the road to Eldoret. It was very abundant everywhere in the upland regions and always appeared in flocks on the edges of the forest or on the acacia-plains. In the evenings large flocks could be seen perched on the dead branches in the tops of the trees. On one occasion I saw a bird coming out of a little hole in a dead tree-trunk and perched on a branch near by. I shot the bird and it then turned out to be a female of E. senegalensis. Whether the bird had its nest in this hollow tree or not was impossible for me to find out, as it was not possible to climb up the tree. — 120 — On the eastern slopes of Mount Elgon this was the com- DQonest of the swallows. In the series of 12 specimens brought home, all of which are in full dress, there are no noteworthy diflferences in the co- lour of the plumage. Two specimens exhibit a lighter tint in the reddish-brown colour of the underparts, two lack the steel- glossy tips to the tail-coverts, but in other respects they are alike.

This race is fairly common in the scrub and on the steppe where it changes into forest, that is to say, in localities where bushes and low trees grow. It conceals itself very well" in the lowest branches and is a shy creature. Frequently I saw it hopping about on the ground picking insects, probably termites or ants,' for these were found abundantly wherever I saw the bird. As Reichenow points out (Vog. Afr. II. p. 436) there is anjastounding variation in the size of this race. The measurements of 4 cTcT have the following appearance: Wing, total length, tarsus, 102 mm. 165 mm. 21.5 mm. 90 mm. 160 mm. 20 mm. 96 mm. 165 mm. 22 mm. 99 mm. 165 mm. 22 mm. - 121 — of 3 99- Wing, total length, tarsus, 95 mm. 160 mm. 20 mm. 98 mm. 168 mm, 21 mm. 93 mm. 160 mm. 20.5 mm. All are in full dress and are shot in the same regions and exhibit no differences in the colours of the plumage worth speak- ing of. Yet the measurements of the length and breadth of the culmen vary very much. The visible portion of the bill va- ries between 12 and 13 mm., the breadth at the base between 6.8 mm and 8 mm. Two young birds, one shot on the 18 th May, the other on the 27th July, are, with respect to colour, as Reichenow has described them (op. cit. p. 435). Both have a wing-measurement of 98 mm., tarsus 21 mm. In specimens from the upland regions the measurements for the length of wing range from 90 to 102 mm in adults. In those from the coastal districts the figure is considerably lower and I therefore consider that I am fully justified in separating them, all the more as there are also other differences present.

Individuals belonging to the tropical coastal regions are in general considerably smaller than the preceding race and, in addition, they have not the clearly marked grey colour on the fore-neck and underparts, but have a pale brownish tint over the more purely white ground. The white colour of the throat is therefore not so pronounced as in the former but shades evenly and almost imperceptibly into the colour of the fore-neck and belly. Further, those from the coast are not dark-grey on the back, but have a much lighter brownish grey upper surface. The respective measurements are: for 2 99 wing, total length, tarsus, 80 mm. 160 mm. 20 mm. 82 mm. 150 mm. 21 mm. for 1 cf 85 mm. 155 mm. 21 mm. Ogilvie Grant (Ibis, 1913, p. 637) gives the wiug- lenght as 80—86 mm. . I have compared my specimens with those in the Berlin Museum and as none of the coastal specimens even attain the minimum for those from the interior of the country I have come to the conclusion that it would be more correct to separate them. — 122 — Rothschild (Bull.

This Fly-catcher was one of the commonest of the small birds met with in the localities through which our expedition passed. The species was found in nearly all places where there are bushes or trees and its vertical distribution on Elgon goes up to 11.000 ft. This species exhibits no individual variations in the colours of the plumage, and all the specimens procured (except one) are exactly alike, both those from the vicinity of Nairobi and those from the summits of Elgon. A young male — from 11.000 ft., Elgon — differs from all the others in having 4 of the tail-feathers tipped with white, but this is probably only a reminiscence of the juvenile feathering, for in young birds the rectrices, as well as the secondaries and the greater wing-coverts, are tipped with white (R e i c h e n 0 w op, cit. p. 440), The lengthe of the wing and the tarsus vary very con- siderably in individuals from the same localities.

This species was common in the thick bush and arboreal vegetation round the Kavirondo Gulf, Victoria Nyanza. It was found right down on the shores and appeared, as a rule, in pairs. All the specimens are in rather abraded plumage. The young bird resembles very much the young of Bradornis palli- dus murinus, but is considerably smaller. The wing -coverts, however, are not so beautifully rust -coloured as the latter but are paler, but in other respects they agree rather well with each other. wing, 64.5 — 67 mm. tarsus, 15 mm.

Londiani, 5.500 ft. — 1 Q juv. 26. 5. Mount Elgon. On the eastern slopes of Elgon this little Fly-catcher was one of the commonest birds. It usually frequented the depths of the forests and was nearly always seen in the highest tops of the trees, flying about with swift and lively movements. Judging from the series of 14 birds which we brought home from Elgon, it seems as if the females, as a rule, are greyer on the breast and belly than the males, which are all more brownish yellow. The young bird has a brownish black head and all the feathers are tipped with yellowish white, the back and wing -coverts are dark -brown with close brownish white, spots, the individual feathers are grey with yellowish-brown extremities and black -edges all round, the upper tail -coverts dark rusty -brown with dark transverse bands, the lower parts yellowish brown with dark longitudinal streaks. The measurements are: wing, tarsus, cTcf 60—64 mm (one 60, one 61, one 62, three 63, two 64). 14 mm. 99 60—65 mm (one 60, one 62, one 63, two 65). 14 mm. — 124 — I found a little nest of this bird, built out on the ends of the slender branches of a Fodocarpus. It was built of dry grass- blades, fibres and the penicils of Composite' plants and con- tained 2 eggs, almost incubated, which strongly called to mind the eggs of Muscicapa striata striata. Grote (Orn. Monatsber., 1920, p. 112 — 115) has dealt with the various forms of Alseonax murinus in an excellent manner, separating 12 different forms belonging to this species. He emphasises here that every geographical zoi.'e, every mountain- range has its own race, but that the different distinguishing features which characterize the separate forms are at times dif- ficult to render in words and it is only when having a large supply of material for comparison that the differences can be distinctly seen. I have compared my specimens with those in the Berlin Museum and cannot find any difference between mine and others from Kilimandjaro, therefore for the present I have named them minimus murinus. It is possible that further studies may estab- lish a new Elgon form. The whole group — previously named murinus — must now according to Grote (Ornithol. Monatsber., 1920, p. 115) be called minimus.

The first specimen of this rare bird was shot in the high- est regions of the bamboo-forests on the slopes of Elgon, at an altitude of about 11.000 feet. As it crept about in the fallen and withered straw, which covered the ground almost everywhere, it was indeed very difficult to discover. The coloration of the plumage blends exceedingly well with the moss-covered, brown- ish-yellow straw, and the bird has — like many other species inhabiting this region — an exceedingly good „protective mi- micry". This race was among the few that followed the slopes of the mountain right up to the highest summits, and I saw it even among the old and withered trees of the Erica forest. Only once did I observe the bird down at the foot of Elgon (this bird was also shot) but otherwise it was found in the sub-alpine regions. Only one of the 4 specimens has the throat greyish white, in the other 3 it is more yellowish - brown on a pale greyish white ground. Reichenow states (op. cit. p. 464) that the length of the wing of this bird is 55 mm. In my specimens the wings have a measurement of 59 and 64 mm for the cfd* and 55 and -- 126 — 57 ram for the 99' It is therefore possible that the Elgon bird represents a larger form, which should thus have a se- parate name. Irides dark-brown outermost, light brown innermost; upper mandible dark- brown, lower mandible brownish yellow; legs dark lead-coloured (Reich enow — dark horn brown). Chloropefanatalensismassaica (Fschr. & Rchw.). — Rchw. II. p. 465. 4 (5(5 ad. 10., 13., 17 and 18. 4; 1 5 ad. 18. 9; Nairobi. This small series of 5 skins lying before me were pro- cured from one and the same spot in the neighbourhood of Nairobi. They were all shot within a little area of about 20 to 25 metres in length, and yet they exhibit such great differences that one might very well make at least 3 sub-species. Even those shot in the month of April, with one or two days' interval, are much unlike each other, but still greater will be the difference if one compares them with the September specimen. One of the April specimens is distinguished by having the whole back a uniform rusty-brown, and the upper tail-coverts of the same yellow colour as the under surface of the body. Another has the back a dark olive-brown, the tail-coverts as in the preceding. A third has the back dark olive-brown, the tail-coverts yellow, but the wing-coverts dark cinnamon-brown, in contradistinction to the other specimens which have the last- mentioned feathers blackish brown with olive-yellow edges. The September specimen has the whole of the sides of the back dark olive-green (without any brown wash), and the upper tail-coverts of the same colour as the back. This specimen has, in fact, a much darker head than all the others (almost black) and coincides most closely with Chloropeta natalensis umbriniceps Neum. (Ornithol. Monatsber., 1902, p. 10). My specimens all have the head brownish black (not sooty-black as storeyi) therefore 1 consider them mostly as intermediates between massaica and storeyi. Bannerraau has pointed out (Ibis 1910, p. 700) that the type-specimen of storeyi was procured on the Nairobi River, that is, in the very district where mine and other specimens of massaica were shot. The specimens brought home by Lonnberg (Birds Coll. Sw. Zool. Exp. B. E. Afr., 1911, p. 83), which are at the Royal Museum, Stockholm, are as dark on the head as mine. Lonn- berg (op. cit.) names them massaica. Grant's opinion (Bull. Brit. Orn. Club, 1906, p. 32), which is also shared by Reich e- n 0 w (Vogelf. d. Mittelafr. Seengeb. p. 302), that the latter form is merely CM. massaica, seems to me therefore to be quite correct. I have examined the type-specimen and found that — 126 — one of my specimens (a young bird) agrees with Neumann's form with reference to the colour of the head. I have come across this race only in a single locality, a swampy, reed-covered bog, where the birds dew about in the tall, powerful reeds. When I returned from Elgon to Nairobi in September I went there again and then shot in the same spot the last-mentioned individual. Reichenow gives (Vog. Afr. II p. 464) as a diagnosis of this family: "die mit anscheinend vollstandigem Schwanz haben nur 8 Federn". This, however, is not correct, for in the three where probably all the tail-feathers are left, there are 10. In 2, where some tail-feathers are shot away, there are only 6 and 8. Even Neumann's form has 10., and so has a specimen pro- cured by Fromm from Iringa (1908). Wing, tarsus, cfcf 63, 63, 64, 65 mm. 22 mm. 9 63 mm. 22 mm.

This is one of the birds of the sub -alpine regions, which is found at an altitude of 10000 — 11.000 feet. At this elevation on the eastern slopes of Elgon lives a little negro-tribe, who had burnt down the forests at certain places. In such places only the charred and half-burnt trunks of trees remained and here I met with this rare bird a few times. Two specimens were shot, but one was so badly shattered, however, that only one remains in the collection. At one occasion another specimen was shot in the northernmost ouf])OSts of tlie bamboo-forest but it was impossible to find it in the thicket and brushwood. The head and upper -parts are of the sam'e olive-green colour, the innermost upper tail coverts yellow. Tiie lower sur- face yellow. This race has, remarkably enough, 12 tail-feathers (the preceding 10) of about the same colour as the upper sur- face of the body. They are yellow on the edges. Irides dark brown; upper mandible dark -brown, lower mandible yellow-grey; legs dark lead-coloured. Wing 60 mm., tarsus 23 mm. I have compared my specimen with a specimen from Meru, shot by Sjostedt (Wissensch. Erg. Schw. Zool. Exp.

In the acacia-country and bush below the slopes of Elgon this race was found rather sparingly. Both specimens are in full dress but have not yet acquired the beautiful blue feathering which they have at pairing time. Individual feathers here and there on the head and back are deep-blue and show off brightly against the greyish blue surface. Reichenow (op. cit.) makes Elminia teresita Ant. a sy- nonym of Elminia longicauda (Sw.) and v. S o m e r e n (Ibis 1916, p. 383) seems to do the same thing. Ogilvie-Grant (Bull. Brit. Orn. Cb. 1913, p. 135) has shown that the former, ranging from the north of Victoria-Nyanza and Albert Nyanza to Oama- roon and Angola "is separable from E. longicauda (Sw.) which is found from Nigeria to the Gold-Coast and Sierra Leone". Sclater & Mackworth-Praed (Ibis 1918, p. 712) have, — 128 — on examining the material in the British Museum, separated 4 races of E. longicauda, and established that the range of this race also extends to Mount Elgon.

Only twice did I see this bird on the eastern slopes of Elgon and both times in small glades in the interior of the for- ests. Although the two specimens brought home originate from the "terra-typica", the original description does not agree with them. For, according to that the lower breast, abdomen and under tail-coverts are white. In these two, it is true, the lower breast is whitish (but strongly shot), but the abdomen and under tail-coverts are grey. Some of the under tail-coverts are white at the tips.

I place all these 8 specimens under the a'bove race, in spite of a few very small diti'erences, which might perhaps make the designation somewhat doubtful. The majority of these spe- cimens are from the Kiambu forests (in the vicinity of Nairobi) and Lonnberg (Birds Coll. by the Swed. Zool. Exp. to B. E. Afr. 1911, p. 85 — 87) has named specimens from these regions T. viridis, which name v. Someren (Ibis, 1916, p. 384) has also given Nairobi specimens. Lonnberg (op. cit.) has described in a very thorough manner the different variations in the plumage of the specimens collected by him, and the birds I procured can be referred now to one now to the other type described by him. In all the cf specimens there can be discerned a pale blue steely gloss on the upperpart of the breast. All the 9 specimens have — 129 -. . also (with the exception of the Elgon specimen) such a very pale gloss on the fore-neck. Only one of the females from the Nairobi regions has a narrow white edge on some of the wing- coverts; in all the others these feathers are black with red edges.

Someren (Journ. of the E. Afr. & Ug. Nat. Hist. Soc, vol. 6, 1918, p. 256) refers his Mombasa specimens to T. p. suahelica, but as the distinctive features which characterise that race are not found in my specimen I cannot refer it there. On comparing my bird with the specimens in the Berlin Museum I came to the conclusion that my specimen must be placed under plum- heiceps, with which it agrees perfectly. The gloss on the head is considerably paler than that of the preceding race and is entirely lacking on the neck and breast. The breast is dark-grey, the belly whitish (with a pale light-grey wash along the flanks), under tail-coverts entirely white (without any brown or brownish red wash whatever). Lower wing-coverts white, some with brownish red tips. Under tail-coverts white. All the wing-coverts are brownish red, and the bird has not the slightest trace of white, either on the wings or tail. The central elongated rectrices extend 115 ram. beyond the 90 mm. long tail. Wing, 75 mm. tarsus, 15 mm. Irides, bill and legs as in the preceding. Ring round eye 3 mm wide. It is rather noteworthy that a South- West African bird, which is not hitherto known farther north than to Tanganjika and the Niassa region, is found in Mombasa. There can hardly in the present case be any question of a casual aberration. — 130 - Parisoma lugens jacksoni Sharpe. — Rchw. III. p. 522. 3 (5(5 ad. 20. 5., 26. 5., 2. 6. ; 1 Q ad. 2. 6.

The bird keeps well concealed among the foli- age high up in the trees, and having perched on any branch in the shelter of the dense leaves, it remains there, motionless and quiet for a long time. When it thinks it has been seen it moves slowly along the branch, — only a few inches — or flies to some other branch near by. It is a slow and poor flyer. The bird is seldom met with in the depths of the forest, but gene- rally on the outskirts or in the sunlit glades. Once I observed a pair where the acacia-forest adjoins the steppe. ' The females are much ligther than the males. One cf spe- cimen from Elgon has an almost entirely black chin. The young birds — whose dress is similar to that of the females — are distinguished by the lower tail-coverts, there being always black transverse bands, about 3—4 mm. wide, on the tips, or just above the tips of these feathers. When a little above the tips of the feathers, these black transverse bands are bounded by white bands on both sides, sometimes the tips of the feathers are black and above this there is a white patch. Tn one specimen a number of the feathers of the under surface have white, narrow transverse bands; all the young birds have, in addition, the edges of the primaries and of the secondaries white, and the tips are, for the most part, white-edged as well. — 131 - Wing, tarsus, d* ad. 113 mm. 22.5 mm.

Thus, the upper surface is blackish with a blue metallic gloss without any transverse bands, but on the lower surface there are found here and there among the black feathers, the whitish feathers, with black transverse bands, of the juvenile dress. The wing-coverts and secondaries are edged with yellow.

Boie — Isis 1826, p. 973 — quotes "Fomatorhynchus" Horsfield, and owing to lack of knowledge about Levaillant's Tschagra, he refers to this family belonging to the Timeliidae. Horsfield wrote " Fomatorhinus" y a spelling that Boie improved to Fomaiorhynchus J'^ Telophomts was improved mostly to Telephonus. — 133 - As the young bird is on the whole similar to the adults, one might possibly — owing to the length of wing — refer it to F. a. minor (Rchw.) but as it was found in the same locality as that in which F. a emini was shot, it is scarcely conceivable that these two forms could be found in the same place.

If we examine the literature on the forms belonging to this group, we shall find that at least 14 are described (Com- pare Z e d 1 i t z , J. f. 0. 1915, p. 54—54 and Neumann, J. f. 0. 1907, pp. 366—379). But not more than one form is given for East Africa, viz. the above-mentioned. Reich enow (J. f. 0. 1915, p. 82) expresses the opinion that this form cannot be considered as a good one, any more than P. s. armenus Oberh. However, as the other 13 forms are North, West and South African respectively, and as the East African specimen of this group cannot possibly be referred to any of them, one should be compelled — if R e i c h e n o w is right — to name at least another new form. On comparing all the specimens belonging to this race found in the Berlin Museum I have come to the same opinion as Z e d 1 i t z (op. cit.), that F. s. orientalis must constitute the name for the coastal form in British East Africa. v. Someren (Journ. E. Afr. & Ug. N. H. S., 1918, p. 256), however, styles the specimen he procured in Mombasa (the "terra typica" for F. s. orientalis) F. senegalus. This is, however, only known from N.W. Africa, Senegal, etc., and there- fore his individual should in all probabilify be called F.s. orientalis. Whether it is correct, as the same author does (Nov. Zool. XXV., 1918, p. 276), to name the Elgon specimen F. s. orientalis, is in my opinion, open to question. — Neumann (op. cit.) has stated that the greater or lesser humidity of the locality seems to play a certain part in the origin of different varieties or forms of this family and in certain districts with about the same natural conditions, temperature and moisture these varieties have become sub-species. Between the South and East African forms of F. senegalus there is a very great variation, then it is out of the question that the coastal form from Mombasa can be identical with the true F. s. senegalus and that the Elgon form again should be the same as the coasal form is not very probable. I have myself one specimen from Mombasa and two from Lumbwa near (Kisumu on Victoaia Nyanza), The former is undoubtedly a good orientalis, but the latter, — which were thus shot far in the interior of the country — differ so much ~ 134 — from both the coastal form and the other forms, that it seems to me that I am justified in giving them a new name. Hence, we should in this way perhaps get two new forms to this group. The specimen from Mombasa is in moult and is already assuming the new dress, which agrees perfectly with Neu- mann's description (op. cit. p. 377). Head, black. Wing 81 mm,, tarsus 26 mm. Telephonus senegalus erythropterus Shaw. — 1 (5 ad. 14. 8.; 1 $ 14. 8.; Lumbwa. The two specimens of P. senegalus group, shot in Lumbwa, also fall within the sub-division, the representatives of which have the two central tail-feathers furnished with well-defined transverse bands. They agree most closely with P. s. erythropterus (Shaw), but the nape and upper part of the head are not entirely black, but very nearly blackish brown, that is to say, some of the feathers are only black on the tips, otherwise they are dark- brown. This may, of course, be because both specimens are in fresh new dresses, the feathers not yet being full-grown nor having the definitive colours. But these two specimens before me also puts one in mind i of P. s. armenus (Oberh), and could be placed under that race. H However, Reichenow (J. f. 0. 1918, p. 82), Neumann (op. \ cit.) and (Zedlitz J. f. 0. 1915, p. 55) consider that this sub- i species is doubtful, and Neumann's objection to the genuine- ^ ness of the race is quite justified and makes me exclude this form from the group. It would also be strange if P. s. orientalis, { which in spite of everything must, however, be looked upon as good, should inhabit the same regions as the one just men- tioned, i For the present I consider it hardly justifiable in increasing the crowd of T. senegalus forms, but rather let the name ery- thropterus stand for my specimens. Wing cT 88 mm., 9 86 mm., tarsus cf9 29 mm. Ogil vie- Grant writes (Ruw. Exp., Rep., 1910, p. 338): „The birds procured by the Ruwenzori Expedition appear to be in- distinguishable from specimens from the Transvaal etc. (T. s. erythropterus apud Neumann) and from Cameron and Gabon {T. s. earner unensis). Like them they have the posterior half of the eyebrow-stripe rufous-buff, whereas in the true T. senegalus it is white". Hence, he calls his Ruwezori specimens T. erythrop- terus Shaw, which name even Bannerman (Ibis 1910, p. 688) gives specimens from Takaungu (in the neighbourhood of Mom- basa on the coast). The same author says that "the bird is common all along the coast, but at Nairobi rare." — 135 — Chlorophoneus abboUi (Richm.). — Rchw. II. p. 560. Maloconotus manningi Sh. 1 (5 ad. 5. 5. Londiani. This rare Shrike, which was first brought home by Dr. W. L. Abbott from Kilimandjaro, is not often found in British East Africa and therefore ornithological literature has not much to say of it. — V. S 0 m e r e n does not even include it in his "Prov. -Check. List of the Birds of East Africa and Uganda". This race occurred on the outskirts of the forests and frequented the dense foliage of the higher branches, where, in spite of its brilliant colours, it was nevertheless difficult to de- tect. The bird's note is a skrill whistle, consisting of 4 — 5 conse- cutive short tones. The specimen agrees almost entirely with the description given by Richmond (Auk. 1897, p. 161) except that the colour of the underparts and of all the under tail-coverts is uniform yellow. Wing 68 mm., culmen 17 mm., tarsus 26 mm. (according to Reichenow bill 15 mm., tarsus 25 mm.). Irides red; bill black; legs lead-grey. The beautiful series of this bird found in the Royal Natural History Museum, Stockholm (collected by Sjostedt: Wissen- schaft Erg. Schw. Zool. Exp. Kilimandjaro, Meru 1905—1906, Stockholm 1910, p. 114) exhibits, as Sjostedt (op. cit.) has pointed out, great variations. Even with reference to the more or less slaty-grey colour of the upper surface there are con- siderable differences, some being predominantly green, others grey. Two specimen from Kilimandjaro in the Berlin Museum (coll. by Sjostedt) have the under surface and flanks predo- minantly green. Further, the back is green, only the shoulder patch being slaty-grey. My specimen has nearly the whole of the back grey, only the upper tail-coverts are green. Chlorophoneus sulfureopectus suahelicus Neum. — Journ. f. Ornithol. 1899, p. 305. 1 Q ad. 12. 8. Lumbwa. This race is found in thick brushwood close to water (Neum. J. f. 0. 1915, p 222). — I only came across it at Lumbwa. Wing 90 mm., tarsus 24 mm. Irides red; bill black; legs lead-grey. Chlorophoneus dohertyi (W. Rothschild). — Rchw. II. p. 567. 1 (5 ad, 21. 5.; 1 2 ad. 21. 5.; Mount Elgon, 6.500 ft. In the dense brushwood and thickets on the slopes of Elgon this race occurred sparingly. Both specimen were shot together — 136 — by Mr. S. Lov^n, and I have carefully sexed them. The male had swollen testes and the ovary of the female was well deve- loped. I cannot agree with Hartert's description of the differen- ces between the male and the female. (Nov. Zool. vol. IX, 1902 pp. 623 — 624). The male specimen is in every respect in conformity with Hartert's account, but the female differs considerably. The red patch on the forehead, counting from base of bill," is only 8 cm. long (in the male 11 cm.). The black patch on the sides of the neck and breast, bounding the red of the chin and neck, does not, as in the male, extend around the eye, but only under the edge, so that the upper eye-border is here olive-green, but black in the male. But the most important difference in the sexes, however, is the different colours of the tail. The tail of the female is rather like that of the young bird, the two central rectrices being dark olive-green, the others dark-brown on the inner-web and on the whole of the outer-web dark olive-green. When the tail is closed it therefore appears to be dark olive green. In the male the tail is a uniform black. It seems remarkable that of D o h e r t y ' s 19 specimens not a single one should be a female. Yet it seems to be the case, in spite of the reasons which H a r t e r t (op. cit. p. 624) adduces for the probability of there being 9 specimens among them. It is true that 99 ^^^ smaller than the males, but the variations among the latter is also great. It is not impossible — though very improbable — that the female described by me is to be considered as an 'aberrant". But one more female was shot, (so badly damaged, however, that it could not be skinned) by Mr. Loven, and I have noted the same differences for this specimen. And in this case the question of "aberration", drops out, but one might then be inclined to assume, (if Hartert's description is correct) that the Elgon form is different from the Escarpm.eut form. This, however, is less probable. Wing, culmen, tarsus, tail, 84 mm., 19 mm., 30 mm., 80 mm., d* ad. 78 mm., 19 mm., 30 mm., 85 mm., 9 ^^' Hartert has (Nov. Zool. vol. IX, 1902, p. 623) described this race carefully but the figure of the cf ad. does not agree entirely with the text, for the narrow black line around the eye, which is rather well-defined in the bird, does not appear on plate IX. If there are really females among Doherty's specimens, which are thus like the males, and the female of the Elgon bird is unlike the male, then the Elgon bird must be considered - 137 — as a new one. We may possibly have here a similar case to that which B o n h o t e (Bull. Brit. Orn. Club., vol. XL, 1920 p. 90) mentions concerning the Mourning Chat. In that race the male of the eastern (Egyptian) form — Oenanthe lugens — is like the female, while in the western form — Oe. lugens halophila — the sexes are very distinct. But Escarpment (from where Hartert's birds were described) is not very far from Elgon (about 150 miles) and if this sexual dimorphism is present be- tween birds of the different localities, and if, like Bon bote, we look upon this dimorphism as an essential character of birds from different regions, which are nevertheless closely allied, we might perhaps have a certain right in looking upon the Elgon bird and the Escarpment bird as diflerent races, just as Bon- h 0 t e considers the above-mentioned Oenanthe to be different species and not subspecies.

Band 9, No 14, 1915) and Zedlitz (J. f. 0. 1915, pp. 59—60) consider it only as a colour variety of L. aeth. aethiopicus while Reichenow (op. cit.), S c 1 a t e r and i\I ack w or t h-Prae d (Ibis 1918, p. 634) and others look upon it as a good sub-species. According to the latter in- vestigators L. ae. aethiopicus should he represented in Abyssinia, north to Kassala jind f^ritrea, south to Shoa and Somaliland ; Zedlitz (J. f. 0. 1916, p. 115), ou the other hand, fixes the distribution to N. 0. and Brit. East Africa but that of L. ae. amhiguus to East Africa between the coast-belt and the Rift-valley. Here L. ae. major commences and is met with in the remainder of East Africa, Uganda and West Africa south to Cameroon. It seems to measifSclater& Mackworth-Praed are right in their description of the distribution of the aethio- picus forms. I also agree with them that L. ae. amhiguus is smaller than L. ae. major. The wing-measurement, however, "about 90 ram.", seems to me to be on the whole somewhat too small, as also that of "about 100 mm." for L. ae. major. The authors do not give any measurements for L. ae. aethiopicus. It is possible — and perhaps probable — that amhiguus is only a colour variety oi aethiopicus and in that case Zedlitz's and Lonnberg's opinion of the distribution of this race will be the correct one. Mackworth-Praed (Ibis, 1917, p. 378) names the bird procured at Thika, L. aethiopicus, thus accepting — 138 — Zedlitz's point of view that year, but later on he gives up this opinion. Ail the 6 individuals shot in the neighbourhood of Nairobi are however typical amhiguus, inasmuch as all of them have the white spot on the wing confined to the primary coverts, and not extending to the outer-web of the greater coverts.

In the regions through which our expedition passed on the eastern slopes I only saw it once. It was found in the brushwood along a small mountain stream. It agrees entirely with Reichenow's description, but it should be added that the feathers of the tibia are not white — like those of the underparts and lower tail-coverts — but are pale yellowish-brown. Perhaps v. Someren (op. "cit ) is correct in saying that the Elgon form is different from the Cameroon, but I have compared this specimen with some 20 birds in the Berlin .Museum (from Cameroon, Tanganjika, Kiwu) but cannot find any difference between West Africans and East Africans.

At the time for change of dress the feathers of the back are not white as in the fresh full plumage, but grey, and the flanks are also faintly shot with grey.

In the vicinity of Nairobi this race was not only the com- monest Laniid but also one of the most abundant small birds. One saw it, in short, everywhere: on the telephone wires along the roads, in the open fields where a few solitary, small bushes grew, in gardens and parks, on the outskirts of the forests, etc. etc. It is not at all shy and one can approach within a few yards of it before it takes fli^ht. At Lake Naivasha, on the 22 nd of April, I found a nest of this bird in a bush near the shore, about 2 metres above the ground, v. Erlanger (J. f. 0. 1905, p. 700) describes the nest as "thick-walled and massive and consisting of all sorts of things", and about the same description is given by v. Someren (Ibis 1916, p. 395). In that case the nest I found cannot be a typical one, for it consisted only of a rather small cup about 11 cm in diameter made of root-fibres and twigs and the walls and bottom were so thin that the three eggs could be seen through them. The eggs were of the same size, colour and markings as those of Lanius senator (v, Erlanger). Reichenow (Vog. Afr. Ill p. 834) has separated the eastern race, which he calls L. humeralis uropygialis, from the north-east African L. collaris humeralis. The former is said to have the upper tail-coverts pure white, by means of which a white transverse band is formed. The latter have the upper tail coverts a brighter grey. In the series of 14 adult individuals, which were brought home, this character varies in birds from the same locality. Some have grey, others almost entirely white, while others again have a distinct white transverse band. I do not therefore find any reason to maintain uropygialis as a good subspecies, in — 141 — spite ot the fact that Lonnberg (Birds Coll. by the Swed. Exp. in B. E. A., 1911, p. 92) and M a c k w o r t h -P r a e d (Ibis, 1917 p. 380) name their Nairobi specimens L. h. uropygialis lichw.. but in conformity with v, Someren (Ibis, 1916, p. 394 and Nov. Zool., 1918, p. 278), Sharpe (Ibis, 1891, p. 597) I call them all by the name given above. The young birds (7 specimens in the collection) have not, as Reichenow (op. cit. p. 608) writes, black tail-feathers and wing -feathers but in the individuals before me (in various phases of feathering) these feathers are dark-brown (cp. Schiebel, J. f. 0. 1906, plate G); in that plate, however, the brown edges to the wings and wing-coverts and the brownish red on the back are too light. Further, the white patches on the shoulder of some of the specimens are not so prominent as in the plate. The blood-reddish brown spot, shown on the edge of the wing of a 9 ^cl. of this race in PI.

Two days' march from Elgon we found this race in flocks of 10 — 15 in number in the scrub. Old and young birds flew about among the low and scattered trees and bushes catching iusects. Below the eastern slopes of Elgon it was common, occurring in the acacia-country. Occasionally I saw solitary individuals on the outskirts of the forests up to an altitude of 7 000 feet. Male and female are rather similar to each other. Yet it seems to me that the males are, as a rule, somewhat darker ~ U2 — than the females, and have closer longitudinal streaks on the underparts. Heuglin (Orn. Nordostafr. I. p. 489) cites, with reference to the colour of the lower tail-coverts, "subcaudalibus albidis" and Reichenow (op. cit.) also says that they are white, and the same writer, in fact. (Mitt. Zool. Mus. Berlin 1910 — 11, p. 223) considers that affinis cannot be separated from the western corvina. However, in these specimens the colour varies from pure white or greyish to brownish white, i. e. the same colour as the breast.

Very common around Kisumu, where at that time of the year it appeared in flocks, sometimes amounting to 20 birds and upwards. I often saw it in the company of Neophron monachus and sometimes they sat in fraternal harmony in the tree-tops. I saw this specieo several times running about on the shores of Victoria Nyanza, where it fed on the dead fish thrown up by the waves. Both 9 specimens are moulting and 2 of the males as well. The former have a wing-measurement of 350, 355 mm. and tarsus 58 mm. These two are young birds which have almost completely assumed the plumage of the adult. Here and there on the neck and head the first brownish feathers are seen among the blue- glossy, new feathers. The two males in moult have a wing measurement of 340, 357 mm, and tarsus 60, 64 mm. The three remaining males measure in the wing 368, 385, 385 mm., tarsus 62, 63, 63 mm. These figures are considerably higher than, for instance, Reichenow's (op. cit.) 310—370 mm., Zedlitz's (J. f. 0. 1911, p. 2) 322, 342, 355,352,365,380 mm., K lei nsc hmi dt's (J. f. 0. 1906, p. 91) 315-377 mm.

Mount Elgon, 7.000 ft. As a rule this bird is named Heferocorax c. minor (vide v. Someren (Ibis 1916, p. 397) Sclater & Mack worth - Praed (Ibis 1918, p. 424) and others). When the train, on the journey from Mombasa to Nairobi, stopped at Kapitiplains Station a flock of these birds was obser- ved out on the steppe. Three individuals were shot. Another specimen was also shot later on at Elgon. On examining these lour specimens closely I made the same observation as Neumann (J. f. 0. 1905, p. 230—231), K 1 e i n s c h m i d t (J. f. 0. 1906, p. 78-82), Z e d I i t z (J. f. 0. 1911, p. 4) viz, that minor is by no means the smaller bird within this group. Sclater & Mackworth-Praed (Ibis 1918, p. 424— 425) however, seem to have entirely overlooked the researches of these three investigators, as they do not mention a word about them but "include all birds from south of the Zambesi with a wing-measurement of less than 330 mm. under the name H. c. capensis. Birds from the north of the Zambesi to the Nile valley (except those from Abyssinia) must be called E. c. minor, with a wiug-measuiemeut of less than 330 mm. The Abyssinian bird will probably require a new name." In general, however, specimens from East Africa have a greater wing -measurement than 330 mm. and since the above- mentioned writers have put this figure as the limit for C. c. minor then — if this were correct — the great majority of them should belong to another form. Probably some mis -print has occurred, for the three German ornithologists, cited above, have shown that the East African form usually has a longer wing than capensis. My four specimens have the following measurements: wing. tarsus, culmen, 325 mm. 67 mm. 56 ram. 9 Elgon. 340 ram. 66 mm. 59 mm. cf Kapitiplain. 335 mm. 66 mm. 57 mm. cf 322 mm. 65 ram. 54 mm. 9 My observations thus comfirm those of the above-named German investigators. Besides, all my specimens are in the moulting stage, hence it is not impossible that in individuals with a full-grown dress the measurements are still greater. Two of the specimens have the fore -neck and head blue- glossy. The back and wings also have a beautiful blue gloss. This race may best be distinguished from C. c. capensis by the size of the bill, it being, as a rule, smaller in the former — 144 — than in the latter (Compare my measurements). Gurney (Ibis 1909, p. 486) calls his specimens from Naiwasha, Heterocorax capensis, but in all probability that is also a case of minor. Corvultur alhicoUis (Lath.). — Rchw.

This Species was for the first time observed at Soy and on the eastern slopes of Elgon it was not rare. Only once did I see it at a higher altitude than 7.000 feet. When I visited the high- est summits of Elgon, over 14.000 ft., I saw two of them, on the steep ledges of the mountain, but as soon as they caught sight of our little troop they flew anxiously — croaking now and then — high over our heads. Whether they were nesting up there or not I was not in a position to find out. Down at our main camp they were almost daily visitors and always kept company with the vultures. They were not timid, but sometimes perched on trees only 5 — 10 yards from my tent. Gurney (Ibis, 1909. p. 486) also mentions the same thing. On one occasion, when I shot one out of a pair, the sur- viving bird flew round the tree where the body of the dead raven remained hanging, and although I fired many shots at other birds it did not seem to mind it but returned again and again. All the specimens are in moult and exhibit no great diiTerences in the colours of the dress, the white band on the breast only being more or less pronounced.

The Drongo is very common everywhere in the Mombasa country and was found in the groves, gardens and parks. At Lake Naiwasha it is also rather common, likewise on the shores — 145 - of Victoria Nyanza. The specimen from Lake Naiwasha is in fresh plumage with a pale blue gloss both on the upper and lower -parts. On the other hand all those from Mombasa, shot 4 days later, are in moult and have very worn and faded dresses with a very faint or no gloss. The two specimens from Mombasa (September) are in full dress with a beautiful blue gloss. Bannerman (Ibis 1920, p. 443) mentions, as a character for the race, that "the upper parts are glossed with blue", and Reichenow (Vog. Afr. II. p. 647) also says that the "lower parts are duller with less gloss". But both the individuals before me have as a beautiful gloss on the lower parts as on the upper. The young bird has pale brown or brownish white edgings to the feathers (Reichenow op. cit.), (v. S o m e r e n , Ibis 1916, p. 398). The feathers of the head, back, under surface and wing coverts are white- ed^ed, Further, the wing-feathers are considerably lighter than in the adults, and the inner -web is greyish white.

They were shot in a clump of trees in the neighbourhood of the town. I must place these specimens under the above-mentioned inasmuch as the outer tail-feathers have an entirely black outer-web. Reichenow (op. cit.) states as the main character of 0. auratus, that the outer tail-feathers are black at the base, but Neumann (J. f. 0. 1905, p. 232) says of a cf speci- men from Omo, that it had only a trace of black on the inner- web of the outer tail-feathers and could just as well be an 0. notatus Ptrs. In that case the character of 0. auratus is slightly minimised. The former should, as a rule, have pure yellow outer tail-feathers, and according to Neumann every specimen not having this character might just as well be either the one or the other. 10 — 146 — Reichenow himself seems to be in doubt in establishing these two Orioles, for in "Vogelf. d. Mittelafr. Seengeb." p, 316 he says, of a specimen from Tanganjika, exactly the same as N e u - m a n n , but adds, that on account of the locality it is placed under auratus. The distribution of 0. auratus stretches from Senegarabia to Niger and North-east Africa, and Ogilvie-Grant (Ibis 1905, p. 201 and 203) mentions it from Melma and Burumba in Southern Uganda. Butler (Ibis 1909, p. 79) has met it in Soudan, at Raffile and Kojali. Supposing that the two species under consideration are good ones, my specimens, at any rate, are not typical 0. notatus, in spite of the fact that the habitat makes it seem likely. Should, on the other hand, notatus and auratus vary in the colour of the outer tail-feathers, as other Oriolus from other territories vary in the colour of the central tail-feathers — it is superfluous to separate them. It is of course not impossible that these individuals are only variations of 0. notatus (a male of which was shot in the same spot). Should this be the case it proves that the character on which this species is based is not good. The cf specimen in question is in the moulting stage and the tail-feathers, except the extreme and central ones, are black for Vs of their length. The measurements are as follows: Wing, tarsus, tail, 133 mm. 22 mm. 75 mm. The female specimen also has the web of the outer rec- trices (except at the tips) black and in the middle the black colour passes onto the inner-web. The other tail-feathers, except the central ones, are not only yellow at the tips of the inner- web but have the whole tip of the feather yellow. This yellow patch is rather wide on the outer tail-feathers, but becomes narrower on the inner ones. Wing, tarsus, tarsus, 131 mm. 22 mm. 80 mm. Irides blood-red; bill brownish-red; legs blueish grey. Oriolus notatus Ptrs. — Rchw. II. p. 656. 1 (5 ad. 29. 4. Mombasa. Reichenow gives the distribution of this bird to East Africa from Wita to the Zambezi country and South-west Africa. Neave (Ibis 1910, p. 259) says that the race is "not common" at Kaluli (Lualaba, Congo), Grote (J. f. 0. 1913, p. 131) men- tions it from Rovuma (German East Africa) and M o u r i t z - 147 — (Ibis 1915, p. 547) considers it to be a "rare bird" at Matopo (southern Rhodesia). It is not rare in the environs of Mombasa, and at Kilindini I observed it in the jungle and even in the cocoa plantations. The specimen is moulting, like the preceding birds, and has the two outer rectrices entirely yellow. Wing, tarsus, culmen, tail, 131 mm. 22 mm. 29 mm. 80 mm. Irides, bill and legs as in the preceding. Oriolus larvatus rolleti Salvad. — Rchw. II. p. 659. 1 (5 ad. 18. 4. Kiambu. — S6 ad. 22. 4.

Reich enow (op. cit.) gives the distribution of this race to East and South-west Africa and that of 0. e. larvatus to South-east Africa. — Neumann (J. f. 0. 1905, p. 235) on the other hand, considers that the former occurs from South Africa, through Mozambique and Nyas?a-land, in the interior of German East Africa to Victoria Nyanza, but Z e d 1 i t z (J. f. 0. 1906, p. 3) comes to the conclusion that the range of the race is South Africa to the Niassa districts. The same author also gives the range of 0. I. rolleti from the White Nile to the south Shoan Lake district. This race, according to Z e d 1 i t z ' s investigations, should have a wing- measurement of 125—129 mm., but the former 135 — 145 (maxi- mum 140 — 145 mm.). Z e d 1 i t z begins his analysis of the Oriolus family by saying that the systematisation of the Oriolus races is rich in difficult problems, the solution of which is by no means made easier by the hybridising which appears to characterise these birds. And no doubt he is right. But I cannot acknowledge him to be correct in what he writes about 0. I. rolleti. For L 0 n n b e r g in his excellent analysis of rolleti and percivali has already established (Birds coll. by Swed. Zool. Exp. B. E. A. 1911, p. 95) that the former is found in the Nairobi districts. Later V. Someren (Ibis 1916, p. 399) also found it here, whence its southern boundary must be moved further southwards. Reichenow has later on (Vogelf. d. Mittelafr. Seengeb. 1912, p. 317) come to the conclusion that an established area of distribution for 0. I. larvatus and 0. I. rolleti cannot be given, but he considers that rolleti seems to occur in the central Afri- can lake districts north and west of Victoria Nyanza. Jackson (Ibis 1910, p. 678) mentions the bird from Takaungu (north of Mombasa) and Mackworth-Praed (Ibis 1917, p. 366) has met it at the Tsavo River (near Kilima 10* Wing, tarsus, 135 mm. 23 mm. 142 mm. 22 mm. 136 mm. 23 mm. 132 mm. 21 mm. 132 mm. 22 mm. — 148 — Ndjaro) and in the Ithanga Hills (south of Nairobi). The lattet writer mentions that he shot two, perched on the same bush, in a locality where Oriolus was not common, and it then turned out that the cT was 0, I. rolleti but the 9 ^ ^- la^vatus. He therefore considers it best not to separate them at present but calls them — in conformity with Shelley — 0. larvatus simply. Perhaps Mackworth-Praed gets nearest the truth, for Reichenow (op. cit.) has shown that there is no precise difference in size (length of wing) between the South-African and Central African specimens, and were I to judge my speci- mens by Zedlitz's measurements, the full-grown specimens should undoubtedly be placed under Oriolus I. larvatus (see above). culmen, 26 5 mm. cf ad.

Afr. 11. p. 658—659) that 0. I. larvatus has a 26—29 mm. long bill, but 0. I. rolleti 23—26 mm. In that case it seems to agree with my specimens. Lonnberg writes (op. cit. p. 95) that of his specimens the one with the longest bill (25 mm.) was without a doubt the oldest. Of my series the bird with the longest bill but one — 25 mm. — is a joung bird, as is clearly shown by the plumage and the colour of the bill. This individual thus proves that Lonnberg's opinion, that the size of the bill varies, is correct. In all the individuals lying before me the central tail-fea- thers are olive-green, while a feather on both sides is somewhat darker olive-green that the central ones and has a black band about 10 cm. in width above the yellow tip. The other tail- feathers have a black basal patch and yellow tips (the yellow patch larger towards the outer tail-feathers). Lonnberg mentions (op. cit.) that he shot both 0. I. rolleti and 0. I. percivali on the same spot in the Nairobi country. And in the vicinity of Elgon (below the eastern slopes) where I shot four specimens of the latter, I also shot a specimen of the former. I have also from Elgon an individual, which to all appearances is an intermediate form between these two, whose tail-feathers have the same colour as the one reproduced in Lonnberg's work (PI. 3, 3b). If both these two forms, rolleti and percivali, are good ones (and the latter thus not a higher developed phase of the former — vide Lonnberg — ) and as they occur together it — 149 — appears to me as if Z e d 1 i t z ' s opinion (J. f. 0. 1916, p. 2) that percivali is not a form of larvatus should be correct. In any case I agree with him in this, that as long as it cannot be proved that along with the "form-circle" of monachus and lar- vatus there is yet a third, it is wisest to name percivali a binary.

Only once did I see this race on the eastern slopes of Elgon.

In several places on the slopes of Elgon I met with this race and it always appeared jn large flocks which frequented both the short and the tall trees in the interior;of the forests. They were not frightened away by shots but calmly remained sitting, calling to each other with a skrill cry, which reminds one of the "laughing" of the magpie. In the stomachs of those shot at 8.000 feet I only found fruits, but the one shot up by the crater- lake of Elgon (at an altitude of about 13.500 ft.) bad its stomach full of insects and spiders. When I visited the crater-lake of Elgon I was astonished to find this race very common so high up in these cold and in- hospitable regions. They flew about among the gigantic Senecio johnstoni which clad the slopes right up to the very summit (see picture) but they were very shy and in spite of eager eff'orts I did not succeed in procuring more than one young bird, which was however, badly damaged by the shot. I saw the old birds repeatedly feeding the young one, which sat shrieking in a Senecio, whence it can thus be considered certain that the young one had been born in these alpine regions. Whether the birds breed on the ledges of the mountain, in holes in the rock (Reichenow op. cit.) or elsewhere 1 was unable to ascertain. It is of great interest anyhow to be able to prove that the vertical distribution of the race at least extends to over 13.500 feet. Two of the specimens in my series are in moult, the others are in full pluamage. In the young bird the primary coverts are, for the most part, black and have near the tips a reddish brown band, narrow on the outer-web, wide on the inner web. — 156 — Wing, tarsus, bill, 158 mm. 34 mm. 29 mm. c? ad. 157 mm. 32 mm. 29 ram. cf ad.

This race was rather common below the slopes of Mount Elgon and I have come across it both in the acacia-country and in the interior of the forests. The males are in full dress but the female has not yet assumed her full plumage, for a number of the feathers of the throat are black with yellow tips and the wing-coverts have all a narrow, brownish white edge (exactly as in the youug bird).

So- meren (Ibis, 1918, p. 280) says that "birds from Nairobi do not differ, though there is some slight variation in wing measure- ments", but my three cf specimens from the Nairobi country all have a brownish red, radiate band below the back throat, while the Elgon specimens, on the other hand are uniform yellow. As a rule they have not, as the latter, the flanks greenish yellow or greenish but yellow. — 157 — The young bird (cT) is very interesting with reference to the plumage, inasmuch as the feathers of the bead are black with reddish brown or yellow tips (chiefly the former). The nape is also garnished with black feathers, the tips of which are yellow, of the same colour as the back, and the upper tail-coverts are greenish yellow (in the adults yellow). Some of the feathers of the throat are yellow, others black with yellow tips and just below the throat it has the same reddish brown band as the old birds. The under-parts are yellow with a pale green wash along the sides, the lower tail-coverts greyish yellow. The wing-coverts have also narrow, greyish yellow edgings. The bill is blackish brown. The female young bird is much unlike the full-grown. The head is entirely black and a number of the feathers of the back are yellow, the posterior ones with yellow or brownish-yellow tips. The ear-coverts black with olive-green tips. The upper and lower tail-coverts as in the male young bird. The throat and the whole of the lower surface yellow. The bill horn, greyish brown (lower mandible lighter than upper). It is noteworthy that one of the old birds has a large, greyish white spot on the posterior half of the upper mandible.

The males sometimes vary in the colour of the dress, and one of them has not only the upper tail-coverts and rump region olive-green but also the lower back. Another has the whole back black, and so on. Likewise, there are differences among the females. The three from Lake Naiwasha, for instance, are all unlike. One has the back entirely black, another (in moult) has the upper part of the back mostly dark-brown, and a third, which is the youngest of the three, has the feathers of the back dark-brown with dark olive-green tips. This last bird has also a pale green wash on the extreme tips of a number of the feathers of the nape. — 158 — Wing, tarsus, 82—85 mm. 23-24 mm. cfcf 76—83 mm.

Thus, whether specimens from the interior of British East Africa are in general larger than others, as for instance, those from Kilimandjaro (according to Sjostedt: Wissensch. Erg. Schw. Zool. Exp. Kilimandjaro, Meru 1905 — 1906, Stockholm 1910, p. 121 — 78—80 mm.), I cannot decide with any certainty. Othyphantes reichenowi nigrotemporalis Granvik.

This race differs from 0. r. reichenowi Fschr. in the male being entirely devoid of the yellow band around the ear and the black patch of the nape merging into the black ear-coverts. In other repects it is like the preceding. The female is exactly like the female of 0. r. reichenowi. This new form of 0. reichenowi is, from what I can see, a good and reliable one. I have examined and compared the abundant collections of reichenowi in the Berlin Museum with mine but I have not found a single specimen which approximates the one described by me. Neither is my bird a juvenile stage of 0. r. reichenowi inasmuch as male and female were shot by the nest and they were in full dress. The young birds are similar to the young of 0. r. reichenowi. Sjostedt mentions, however, (Wissensch. Erg. Schw, Zool. Exp. Kilimandjaro — Meru 1905-1906, Stockholm 1910, p. 121) that he had observed that the yellow band around the temporal region was missing both in old birds and young. 1 have gone through the bird collections which Sjostedt brought home, found in Stockholm, but have not found a single male without this band. Sjostedt does not mention (op. cit.) whether the lack of this yellow baud applies to cfcT or 99> but as regards 99 it has already been established by Fischer that they have the sides of the head entirely black. Sjostedt's statement should, from what I have seen, undoubtedly apply to 99- Below the eastern slopes of Elgon, at about 6.500 ft. above sea -level, this Weaver Bird is common and is biologically in agreement with 0. r. reichenowi. On the 6 th June I found a nest containing 2 newly hatched nestlings and one egg, v. Someren (Ibis, 1916, p. 404) says that many nests are — 159 — found on the same tree but, as a rule, only one is occupied, and it proved to be so in this instance, for, out on the tips of the slender branches of a low bush, about 2 meters from the ground there hung two nests, only one of which was occupied. The nest was semi-globular iu shape with the entrance from below. The measurement from the outer edge of the entrance- hole to the farther side of the nest was 20 cm. The entrance of the nest itself was 5 cm. across and the walls of the nest were thick and firm, built of dry grass-stems, but were lined with different kinds of grass fibres. The nest hung in the fork of two branches, and long, tough grass-stems, twined into the walls, were twisted round these branches, letting the nest hang freely, so that even if the wind set the branches swinging, the nest kept the same position. The egg, found in the nest, measured 22.5 X 16 mm. and weighed 0,51 gr. The shell is dull glossy white, with large or small brown and brownish red spots over the whole surface. The larger spots, which are in the majority, measure up to 4 or 5 mm. long and 2-3 mm. wide gathered in a feeble attempt to form a calotte at the thick-end. The ground spots are bluish grey and greyish violet. The egg resembles an egg of Sitta europaea but also strongly recalls the eggs of Hyphantornis jamesonii (Swynnerton, Ibis 1916, PI. XIX, 12.)

But as I have not seen any specimen of the bird in question I cannot express any opinion as to its position with reference to reichenowi or other forms. Hyphanturgus stephanophorus (Sharpe). — Rchw.

Mount Elgon. 1 saw this interesting Weaver, whose nearest ally, H. melano- gaster, is found in West Africa, a few times on the eastern slopes of Elgon. V. Someren (Nov. Zool. XXV, 1918, p. 280) says — 160 — that it is "fairly common" on west Elgon. In the regions of east Elgon that I visited, it can hardly be said to be common, but rather the contrary. On the 8 th June I found a nest of this bird. It was built in the depths of the forests, among the lianas, on the outermost branches of a little bush and contained two eggs of nearly the same colour as those of the preceding race. 1 did not shoot any of the parents nor did I take the eggs, hoping that a few days later the clutch would be increased to 3 eggs. Returning to the place two days later I found the nest empty and the birds gone. They had possibly been disturbed when 1 examined the nest the first time and thus abandoned it, but I hardly believe that they had carried the eggs themselves. Grant asserts (Zool. Res. of Ruw. Exp. 1910, p. 273) that the female of this race differs from the female of melanog aster, the latter having the whole crown yellow while in the former the yellow extends to the posterior edge of the eye. In this specimen the yellow patch in question stretches a little way (2 mm.) behind the eye. The throat is entirely yellow. Wing 74 mm,; tarsus 21 mm. Irides red; bill black; legs dark lead-grey.

At Kiambu (in the neighbourhood of Nairobi) I frequently saw them in large flocks, and once 12 birds were shot out of a single flock. All were females. They vary in the colour of the dress as well as that of the bill, and most of them (10 in all) have the posterior half of the lower surface whitish, others have all the underparts pale yellow. In the former there are some with greyish white, others with whitish -yellow lower tail-coverts; the latter have yellow ones. As a rule the lower mandible is lighter than the upper, but two have the lower mandible dark and of the same colour as the upper. Wing, tarsus, cTcf. 80—85 mm. 23 mm. 99. 77-86 mm. 21— 23 mm.

III. p. 68. 1 Q 22. 8. Kendu. On the shores of Kavirondo-Bay at Kendu this race was common. However, believing it to be the same race as that I had procured several specimens of at Kisum {S. dimidiatus) I shot only one individual. Og.-Grant (Zool. Res. Ruw. Exp. 1910, p. 276) has given an excellent table to distinguish 99 of the two closely allied 8. jacksoni and dimidiatus from one other and mentions as a character for the former that "the culmen is nearly always straight", in the latter "culmen is curved". In this specimen the colour of the bill too is unlike all 99 of dimidiatus, for the lower mandible is entirely light greyish- brown and the upper mandible somewhat darker. In 99 of dimidiatus the upper mandible is black, just like the edges of the lower mandible. Wing 73 mm.; tarsus 23 mm.

This bird was very abundant all along the shores of the Kavirondo gulf, especially in places where brushwood was found. As a rule large swarms were seen frequenting the water's edge, where their nests hung everywhere on the branches of the bushes. V. Someren (Ibis 1916, p. 410— 411) has exhaustively dealt with this race, and so has Og. -Grant (Zool. Res. Ruw. Exp. 1910, p. 275—276) and the descriptions of both these writers complete one another quite favourably. All the males are moulting and agree almost completely* with each other in the colours of the plumage. Still, one of the specimens is somewhat lighter in the brown colour of the breast, but this is surely owing to the dress being worn and faded. With reference to the chief character of the males of this race: the extent of the black patch on the head etc. opinions seem to be divided, v. Someren says (op. cit.) "the colour of the mantle is separated from the black of the nape by a very narrow yellow band", but in another series "there is a wide yellow band separating the black of the head from the golden olive of the mantle", but Og. -Grant (op. cit.) states that "the black of the head does not extend beyond the occiput and is divided from the olive -yellow mantle by a bright yellow collar". In skinned birds the width of this yellow band may obviously vary, depending on h o w the bird is preserved. If we compare the two pictures of this bird (R e i c h e - now: Zool. Jahrb. Bd. I, Taf. 5 and Antinoti&Salvadori: Ann. Mug. Natur. Geneva, vol. IV, 1873, Tav. Ill) the different opinions as to the extent of the black of the head is evident. Reichenow mentions (op. cit.) that the bill of dimidiata is larger than that of jacksoni (the former 16—17 mm., the latter, 14—16), and with reference to the shape of the bill in these two forms I may refer the reader to the preceding race. V. Someren does not consider it impossible that we have to do with two "distinct subspecies" of dimidiata. Nor is it likely that two forms of the same "form-circle" should occur in the same locality. The dissimilarities which he gives are exem- plified in my collection, for, among my four male specimens from Kisumu I have three belonging to his series No. 1 and one to No. 2. It seems to me more probable that this is nothing but a case of individual differences. * — 163 — In youDger males in the transition to the full dress the yellow band on the nape is scarcely indicated, tbut shades almost imperceptibly into the olive-yellow colour of he back. Whether the size of the bill is, or can be, conclusive in placing the two races, I cannot decide with certainty, as the material I have had for examination has been too small. Still, it seems to me to be unlikely. With reference to the colour of the females there are also small differences. Thus, two have predominantly pale brownish markings on the mantle, while the other two incline more to grey. And one specimen (rather young) has the head a more uniform olive -green and the dark streaks to the feathers are not so conspicuous as in the others. There are also differences in the brownish wash of the belly. When comparing my male specimens with the collection of .^Weaver birds in the Berlin Museum I found that they agreed perfectly with the specimens found there of fischeri Rchw. (type- specimen also in Berlin) from Wadelai and other districts, and also with two specimens in Stockholm from Rutschuru, East Congo (vide Lonnberg: Arkiv. for Zool, Band 10, No. 24, Stockholm 1917, p. 27). Thus, when v. Someren (Ibis 1916) calls specimens procured from Uganda and East Africa dimi- diatus, it seems remarkable that a North Abyssinian bird (type from Kassala) should go so far south as Victoria Nyanza. Ogilvie-Grant has, it is true (Zool. Res. Ruw. Exp., 1910, p. 275), written that the latter bird occurs "from Wadelai in the north to South Ruwenzori in the South and eastwards to En- tebbe", but he seems to have overlooked the fact that dimidiatus up to that time was known from North Abessynia and, according toJagerskiold (Res. Swed. Zool. Exp. to Eygpt & White Nile 1901, Upsala 1903, p. 2) from Kaka in Shelluk on the White Nile. Whether G rant's specimens are dimidiatus and not fischeri is therefore doubtful. However, Sclater&M. -Praed (Ibis 1918, p. 438) have remarked that dimidiatus "has never been found between the type locality and the Lake District" and that "it seems probable, therefore, that there was some mistake about the type locality and the bird is not a Sudanese form at all", ' The range of dimidiatus thus coincides with that of fischeri. V. Someren, who has seen my specimens, shot on the same spot as his, has also fixed them as dimidiatus. And jud- ging from the description in "the Ibis" they agree perfectly. But according to Reichenow (Vog. Afr. III. p. 69) dimidiatus has the breast and belly chestnut, upperparts golden yellow (see also plate III Ann. del Mus. Civ. Stor. Nat. Geneva, 1873), which neither v. Someren's specimens nor mine have. They should thus undoubtedly be named fischeri. 11* ^ 164 — The question then is: Is dimidiatus a synonym of fischeri or is it] not? I have not seen the type of dimidiatus and there- fore cannot express any opinion about it at present, but if the dimidiatus type does not originate from Kassala, and Grant has already in 1910 established that the norther limit of the bird is Wadelai, there is much in favour of its being, in spite of the dissimilarities, a synonym of fischeri. But the latter form was first described in 1887 and the former in 1873, therefore I have retained the older name. Seth-Smith (Ibis 1913, p. 493) calls his specimens from Mpumu (in the vicinity of Kampala on Victoria Nyanza) Eyphantornis dimidiatus fischeri thus making fischeri a race of dimidiatus. Further investigations must decide whether his opinions or mine is the correct one.

I have examined Jagerskiold's specimen, shot on 23. 2. 1901, from the White Nile (fixed by Reichenow once as dimidiatus) and found a rather strong likeness to a number of my female specimens. This specimen is by mistake marked "young male", for it is a female bird. It differs, however, from my 9 specimens — all of which have a more or less marked olive -green wash on the tail-fea- thers and on the outer-web of the primaries and secondaries — in having the tail-feathers more greyish brown and only the outer-web light olive-green, the olive-green edges of the primaries and secondaries being considerably paler. One of my specimens, having a rather worn dress, agrees very well with the White Nile discovery. It has the following measurements: Wing, bill, tarsus, 72 mm. 16 mm. 22.5 mm. Even the fore-neck of this specimen is greyish brown, but in all my specimens it is brownish yellow. Whether the paler dress of this Nile bird is a result of its having been shot in the month of February, the plumage being thus more used and abraded or (which is most probable) whether the northern form is different from mine is a question I dare not decide from this single 9 specimen. culmen, 18 mm. d*. 17 mm. cT. 17 mm. cf. 18 mm. cT. 15 mm. 9- 17 mm. 9. 16 mm. 9- 16 mm. 9- 16 mm. 9- 14.5 mm • 9 Juv. — 165 — Xanthophilus xanihops Hartl. — Rchw.

On the 6 th June I found about 20 nests of this race within a very small area, but only three of them contained eggs. All the nests were built about 30—70 cm. from the ground between two strong grass-blades, and it was very interesting to see how such a nest came into existence. The birds first stretched a few blades of grass from stalk to stalk, the ends being twisted several times around the latter, thus enclosing a space of about 5 cm., almost quadrangular in shape. Then a number of new grass blades were interwoven with the former so that a firm and safe connection was effected with the boundary lines. Other blades were then woven into the four corners, which were gradually rounded otf, and the original square opening became circular, when the business of building the nest itself began. Very diligently the birds interlaced the long blades of grass into the upper edge of the firm structure, fastening them to the lower one. Then one of the birds crept inside the loose and delicate bag-shaped shell, arranged the accumulated material, fastened shorter blades together and gave the future nest the form it was to have. It was surprising to see how fast the work pro- ceeded and in what a short time they succeeded in getting everything arranged. The work of building was carried on without ceasing so that in a day the artistic, little dwelling was quite ready. It had then the form of a pouch about 8 — 10 cm. high with firm, rather thin walls and with an entrance of about 4 cm. diameter. The same spot, where this race occurred commonly, was also frequented by Vidua serena and Urobrachya ph. phoenica in great numbers. The four male specimens are exactly like each other and agree with Reichenow's description (op. cit.). The other two, on the contrary, have the dark- brown feathers of the nape edged with red. The extent of the red patch of the head also varies a little. The female agrees also with Reichenow's description, but has the superciliary stripe distinctly yellow.

Id the thick rushes around the Gulf of Kavirondo, at Kendu, this species was very numerous. As a rule they were seen in considerable flocks among the Cyperaceae where they flew about the reeds with great activity. At that time of the year all the old birds were in a very advanced phase of moult. A cf young bird in transition-dres is very interesting. The feathers of the head are black with wide, brown edges; the back and the upper tail-coverts black, edged with rust-brown (here and there a roseate feather); chin and throat as in the young bird but with a few solitary brick-red feathers interspersed; the feathers of the belly black with white tips.

The one coming next has numerous red feathers among the predominant black- brown ones on the nape and back. The sides of the. head dark- brown, the nape scarlet red. The under surface black with large light yellowish brown feathers here and there, congregated to form almost to a band across the breast. The third is more like a young bird, but has near the nape a hidden ring of scarlet-red feathers. One or two of the upper tail coverts with a red wash. Lower tail coverts pale yellowish brown. In other respects like the young bird. The female resembles 9 of Pyronielana nigrifrons, but is darker on the upper part. The yellowish brown patch on the fore-neck and breast somewhat paler and without the dark streaks.

At every place through which our expedition passed this race was one of the commonest of the small birds. It was mostly met with in the bush-country, but on Elgon I came across it almost everywhere in the depths of the forests, out on the grass steppe and in the acacia-country. When we marched along the roads on the way to Elgon, we continually saw this Weaver bird sitting in the top of some little bush by the way-side. In the series of 10 males found in the collections not a single one has black thighs, which Reichenow gives (op. cit.) as the main character for this form. Some of the specimens have these parts entirely yellowish brown — like the females — others have chiefly brown feathers with here and there a few black ones, and then again some have mainly black thighs with - 169 — brown feathers, or black with brown tips, interspersed. All of them have a larger or smaller number of feathers with wide, white or pale brown tips on the middle of the breast. Lonnberg writes (Birds coll. Sw. Zool. Exp. B. E. Afr., 1911, p. 103) that a male from Kutu 25. 1. had swollen testes and the same was the case with another male shot two months later. This proves that the birds breed at different times of the year. My observations corroborate this statement, for a male from Kiambu 18. 4. had swollen testes and so had others from Elgon on 28. 5. The young birds (99) resemble the old females very much. Yet they are considerably lighter. In the adults, for instance, the fore-neck is dark yellowish brown, but in the young birds it is pale greyish brown. The lesser wing-coverts, which in the former are distinctly olive-yellow, are in the latter pale olive- yellow, and so on.

At Eldoret and in its environs this race was comraon, appea- ring as a rule in small flocks of 5 or 8 in number. They fre- quented the tall grass on both sides of a little stream, in the company of Penthetria laticauda, but in contradistinction to the latter they were very timid. On and below the eastern slopes of Mount Elgon I met the race a few times, but I do not think it can be said that it is common here. Here it also inhabited the swampy grass regions and was sometimes seen in the company of Vidua serena. At this place I never saw the females together with the males. — 170 — In the month of July, when the young were full-fledged, they visited — then in much larger flocks — the maize fields of the natives.

This race was one of the commonest in the grass country below the eastern slopes of Elgon. In the series of 13 males brought home there are rather great differences, which are, however, not of the kind to justify a separation of forms, even if, at first sight, this may seem to be the rvght thing to do. All the specimens from Nairobi and its environs have a number of the feathers of the red patch on the head and neck tipped with black, and although all have their backs broadly striped with brown and have thus not yet assumed the full dress, two of them had swollen testes (see Lonnberg: Birds coll. B. E. Afr. 1911, p. 103). The red band on the fore-neck varies also in shade, so that some have scarlet-red, others orange-red, etc. etc. The lower tail-feathers greyish white or brownish white in the tips. The specimens from the Elgon regions all have the band on the fore- neck considerably broader and of a darker red. Whether this character is sufficient to name a new form or not is difficult to decide. Yet, it seems to me that this may simply be regarded as a more developed phase towards the full nuptial plumage, which also appears from the fact that the wide, brown edges to the feathers of the back and to the under tail- coverts in the Nairobi specimens (April) have almost entirely disappeared in the Elgon birds (end of May — beginning of June). In the series there is also found every desirable grade of transition from the brown (if I may so call it) to the entirely black full dress. What at once catches the eye in these specimens is that those with the most developed plumage, and evidently the oldest, 79 mm. 23 mm. 160 mm. 80 mm. 23 mm. 165 mm. 77 mm. 23 mm. 165 mm. 75 mm. 23 mm. 180 mm. 79 mm. 23 mm. 160 mm. 80 mm. 23 mm. 190 mm. 81 mm. 23 mm. 160 mm. 76 mm. 23 mm. 180 mm. 77 mm. 23 mm. 135 mm. 77 mm. 23 mm. 125 mm. 79 mm. 23 mm. 150 mm. 81 mm. 23 mm. 160 mm. - 171 — have by no means the longest tail. Judging from my material, one might sooner assert that the opposite is true, for all the Elgon specimens, as compared with those from Nairobi, have shorter tails (compare the table below). In proportion as the dress approaches and finally reaches the complete plumage, the light tips of the tail-feathers gradually disappear until the feathers finally become entirely black.

One of the Elgon specimens differs also from all the others in that the red patch of the head extends on to the fore- head, reaching almost to the base of the bill.

Very abundant at all places visited by our expedition. Yet I never saw it on Elgon or below its slopes. Eldoret was the most northern place where the bird was observed. As the pairing time seems to fall in the end of April and in the beginning of May, I saw time after time during these periods large flocks of both males and females passing over the grassy plains, and at Eldoret I shot 18 birds, 9 males and — 172 — 9 females, out of a single fiock that was flying past. Gurney (Ibis 1909 p. 489) mentions that he has seen flocks of 40—50 females, accompanied by only 7 — 8 males, and the same writer gives a good description of the displays of the males. In the beautiful series of 18 males from various localities there are no noteworthy diff'erences. One or two have on the belly a few brownish feathers in the otherwise black plumage, but these are only reminiscences of the juvenile dress.

On the parts where they should be found one can, however discern darker patches, which would probably assume this green-glossy colour later one.

Fiom the description it does not seem to differ in any noteworthy degree from Har- t art's neumanni. 1 have compared my specimens with others from Kilimanjaro, collected by Sjostedt, in the Stockholm National Museum, and it seems as if the latter were in general darker than Elgon specimens. A specimen found in Stockholm from Kenia (thus wamhugensis, according to Mearus) exhibits no difference from the Elgon birds. That wamhugensis should be considered a good form seems doubtful to me. I have, it is true, not had any specimen for comparison, but have in the series from Elgon young birds which agree perfectly with Mearn's description (op. cit), whence I think it quite probable that this form is only a juvenile phase of prinoides. Finally, as far as neumanni is concerned, I entertain great doubts in accepting it as a good, geographical form, inasmuch as among the 14 Elgon specimens even this type is represented. When studying the forms belonging to this species I have found that the young in general have a more reddish brown head than the adults, and that the upper parts are also predo- minantly brownish, sometimes uniformly coloured, the tail brow- nish, and the feathers oftenest with rusty-brown edgings. Under parts whitish, mingled with grey on the sides. The throat almost pure white. The young birds have also the bill dark-brown with the posterior half of the lower mandible yellowish. Among the 10 full-grown specimens there are rather great differences, aud they can be referred now to one, now to another of the previously mentioned forms. Thus, some have the whole of the lower surface greyish, others have a whitish area along the middle of the abdomen. A certain number of them have the head rusty-brown, others dark greyish brown and in some the crown is more spotted, with dark centres to the feathers, than in others etc. The majority have the whole of the upper parts brownish black, but in a few they are Ifghter, brownish grey, approaching the young bird's. The tail-feathers are in all of them more or less brownish grey. As 12 of the 14 specimens were shot at the same time and within a limited area and there being so great differences which can be referred to the distinctive features distinguishing the various forms described, this goes to prove that a number of these forms can hardly be considered as good ones but only as individual variations in a bird which exhibits locally great variation in the colour and design of the dress, and 1 am con- vinced that future investigations of C. prinioides will corroborate this opiuinion. Neumann says (Jouru. f. Orn., 1900, p. 304) that only two birds have any likeness to prinioides, namely, two specimens — 231 — from South Africa under the name of subruficapilla found in the Berlin Museum. But hunteri is undoubtedly closely related to prinioides and resembles it very much and also occurs, according to Reichenow, together with it, 1 have compared my specimens with the type specimens and others in the Berlin Museum and found that the Kikuyu specimen agrees perfectly with the type, but that those from Elgon are in general somewhat darker. The Elgon specimens have as a rule a larger wing-measure- ment than N e u m a n n' s type, but in the Berlin Museum there are prinioides specimens from Meru (collected by Sjostedt) with a wing-measurement of 60 mm. and others have above 60 mm. Perhaps the Elgon bird is a distinct form which is larger than the others, for it could hardly be distinguished from the others by any other character. But as the figures in the present case vary so considerably I do not yet consider that I am jus- tified in establishing a new form.

In the grass-country around Lake Naiwasha this race was found in company with others of the same family. The male agrees perfectly with Mearn's description of the type specimen from Lake Naiwasha, but the female has not the brownish-black centre on the feathers of the mantle, but is more uniformly dark-brown, nor are the feathers of the head striped with blackish brown. Reichenow throws out the suggestion (Journ. f. Orn., 1918, p. 104) that aequatorialis coincides with his semifasciata, of which I have examined the type specimen and 6 others in the Berlin Museum collections, and although there are rather great similarities between these two forms I am yet of opinion that they should be kept apart, for as Mearns pointed out this form is considerably larger and besides has not, as semifasciaia, only a black spot on the inner web of the tail-feathers, close to the tip but has a clear band across both webs. — 232 — Wing, tarsus, 69 mm. 26 mm. d* 58 mm. 24 mm. 9 M earns gives the measurement for aequatorialis as: cfd* 66,1 mm., tarsus 24 5 mm., 99 57 mm, 23.6 mm. The measurements for the specimens before me are greater, it is true, but nevertheless I still place them under this form, on account of the other similarities. V. Someren names a related form: fischeri (Ibis, 1916, p. 451) and in his "Prov. Check-list of the Birds of B. E. A. and Uganda", 1917, p. 57, refers this name to Reich enow: Journ. f. Orn., 1911. However, there is neither in that year nor any other year any form of suhruficapilla described by Reichenow under this name, but certainly a Cisiicola chiniana fischeri in Journ. f. Orn., 1891, p. 162. Cisticola strangei holuhii Pelz. — Rchv?. Ill, p. 545. 4 (5(5 ad. 8. 6., 19. 6., 24. 7., 25. 7. Mount Elgon. This bird occurred less commonly on the eastern slopes of Elgon up to about 7000 feet. Zedlitz (Journ. f. Orn., 1916, p 82), following. Neu- mann (Journ. f. Orn., 1906, p. 266—267), distinguishes three forms belonging to this circle, strangei, argentea and hohtbii, of which the one occurring in East Africa is the above-named. When Zedlitz treats of the systematisation of the strangei forms he does not express any opinion, remarkably enough, of Mearns' analysis thereof (Smithson. Misc. Coll., vol. 56, No. 25, 1911, p. 4 — 5). Mearns mentions strangei, pachyrhijncha and a new form, kapitensis, and he gives a comparative description of the three of them. He also speaks of argentea and considers this "apparently as a subspecies of C. strangei^\ According to Mearns and Zedlitz we should thus have to include the following forms: 1. Cisticola strangei strangei (Fras.) Wing 69 mm , tarsus 29 mm. (ace. to Mearns). Hab. West Africa from Senegambia to Angola. 2. Cisticola strangei holuhii Pelz. Wing ^1—12 mm., tarsus 27—28 mm.

Wing 67.6—68 ram., tarsus 28.5—29 mm. • • ■ . Hab. Kapiti Plains (British East Africa). Whether Icapitensis is a good form or is a synonym of hohihii — which is very probable — I have not been in a position to decide, v. Someren (Ibis, 1916, p. 451) says that "a freshly-moulted specimen in fine, clean, dark dress is an August bird. Birds in the light brown plumage have been found breeding". Thus it seems as if dark and light specimens occur within the same area and that this difference is of no syste- metic value but is only due to the different seasons, whence it is probable that careful studies of the strangei- forms described will reduce their number. The whole of the upper parts are predominantly grey, although the head has a slight tint of brown. The rusty-brown colour on the tibia varies quite considerably in these four from pale to dark rusty-brown. Wing, tarsus, 67, 68, 70, 72 mm. 27—28 mm. Irides brownish-red; bill blackish (lower mandible with light tip), legs flesh colour. Sclater and Mackworth-Praed (Ibis, 1918, p. 647) makes the West African strangei a form under natalensis, which is probably the most correct, but having had too little material at my disposal I cannot give an opinion of the relative affinity of the various strangei forms or of their relation to natalensis. Cisticola tinniens suhrufescefls Granvik. 1 (5 ad. 10. 5.; 1 Q ad. 11. 5. Eldoret. This bird, so rarely met with in East Africa, was found on the rush-clad banks of a little stream flowing through the grass-plains. Reichenow gives the range of this bird to South Africa, extending northwards to Angola and the Transvaal (but acc-ording to Jackson: Ibis, 1901, p. 56, also found in East Africa). Jackson says that "in Nandi it is plentiful in the marshy hollows", and the same writer has also procured this bird from Mau. This Warbler resembles C. eryihrogenys very much but differs from that in having the forehead uniform rufous and the black stripes commencing just in front of the eye. (Ogilvie- Grant and Reid: Ibis, 1901, p. 653). The male is somewhat darker reddish-brown than the female and has scanty black stripes on the neck and the black feathers of upper parts edged with Irownish grey. Further, the tibias — 234 — are dark rusty-brown. The female lacks the black stripes on the hea<], which is thus here uniform rufous; tho feathers of the back are edged with light greyish brown. The tibias pale rusty-brown. Id other respects they are in agreement with Reich enow's description. Wing, tarsus, 58 mm. 22 mm. 59 mm. 21 mm. Irides dark-brown; bill black (lower mandible with greyish- blue spot); legs faintly flesh-colured. The East African form of iwmevs differs from the South African in the head being reddish brown (in the South African rusty-brown) and in the long length of its wing. In South African specimens this is 50 — 55 mm. Cisticola rohusta ambigua Sharpe. — Bull. Brit. Orn. Club, vol. XI, 1900, p. 28. 2 (3^ ad. 10. 4. Nairobi. — 1 ^ ad. 11. 4, Ngong. — 1 (5 ad. 17. 4.

Orn., 1906, p.p. 264—266) has dealt with the forms of rohusta in detail and separated 5 seemingly good races. I have before me a series of 20 specimens which must all — in spite of small differences — be placed under ambigua. According to Neumann (op. cit.) this form is characterised by being a darker red on the head, right from the crown. The dark streaking of the frontal plate very dull, in many it is not present at all. Pure white or almost white tail tips. Wing: d* 66 — 71 mm., 9 56—60 mm. With specimens from Nairobi, Ngong and Kiambu (thus from the Kikuyu country) Neumann's description agrees en- tirely. Yet in some the head patch is more red-brownish, in others brownish yellow. All of them have the dark streaks faintly marked. The other specimens from Eldoret, Soy and Elgon are of another type and agree with the description v. Someren has given of birds from Uganda (Ibis, 1916, p. 453) Whether these are aberrants of ambigua or not is doubtful, v. S o nj e r e n , however, has at any rate not expressed any opinion but styles them only C. ? Among these 13 specimens there is only one (9) which approaches the true ambigua from the Kikuyu-country. It therefore seems most probable to me that the dilTerence present is only a difference accompanying the seasons. They cannot be — 235 — coLsidered as nuchalis (from the West-side of Victoria Nyanza) for, according to v. S[omeren (op. cit.) this has "a dark brown head with a few dark markings", which does not agree with any of the ones before me. Reichenow (Vog. Afr. Ill, p. 555), who is the author of the bird, gives the wing to 55 mm., Neu- mann gives 54 mm., but v. Someren 63—66 mm. for cT, 54—60 mm. for 9- A number of these specimens recall, as regard the colour of the head, the north-east African robusta, but do not attain the measurement of that form. With respect to the colour of the lower surface these 13 specimens exactly resemble those from tho Kikuyu country. The young birds from the Elgon district differs distinctly from the full-grown in the tail-feathers being dark greyish brown, and all of them have a distinct whitish tint on the under parts (in these characters they recall naialensis to a certain extent). The head has not yet acquired the brownish red colour of the adult but is of the same colour as the back and provided with dark, wide streaks.

Someren (Ibis, 1916, p. 452) says, however, of this race that it is "fairly common, but difficult to procure". Breeding-time seems to fall in the month of April, for this female specimen had well developed eggs in the ovary. In contradistinction to the following this form is considerably lighter — 236 — and paler, especially the lower surface, which is pure white, the throat likewise. The fore-neck and flanks are pale yellowish brown. The rump is yellowish brown. Wing 47 mm.; tarsus 20 mm. Irides dark-brown; bill yellowish brown, upper mandible darker; legs pale flesh-coloured.

Fairly common in the grass-country in the Elgon re- gions and at Eldoret, and differs quite distinctly from the preceding by having the head, as a rule, more rusty-brown, the rump rusty brown and the under parts of the body almost uniformly pale yellowish brown. On the other hand 1 am not able to find any noteworthy difference in the colour of the tail- feathers, although Reichenow (op. cit.) intimates that such a difference exists. In the characters given they differ, however considerably from the preceding and therefore I have given them Reich enow's name. In some respects — measurements, colour of upper parts — they even agree fairly well with Heuglin's eximia (Ibis, 1869, p. 106) and one migl>t just as well consider them to be intermediate between that race and ugandae.

This species occurred up to about 7.500 feet on the eastern slopes of Elgon and was common in the open grass-country. All the Elgon specimens are greyish brown above (not brown, as Reichenow states), otherwise they agree with the description (op. cit.). According to Reichenow this species differs, among other things, from nigriloris in the tarsus being shorter: in the latter 26 — 27 mm., in the former 24—25 mm. As appears from the table below the length of the tarsus of these cfcT individuals is, without exception, 27 mm., whence the difference between the species mentioned does not seem to ex- ist.

In the grass-country below the slopes of Elgon this little Warbler was found not uncommonly. The four specimens are almost exactly alike and have the faint, dark streaks to the feathers of the back. Only in respect to the colour of the head do they vary a little, two of them being a little lighter than the others, the latter having a dark- brown head patch. In other respects they are in accordance with Reich enow 's description of C. rufa. The measurements agrees better with Neumann's (op. cit.) than with R e i c h e n o w ' s. Wing, tarsus, 50, 51, 52, 52.5 mm. 20 ram. Irides brownish red; bill dark greyish brown (lower man- dible lighter); legs pale ilesh-coloured. Sclater and M. - P r a e d (Ibis, 1918, p. 655) are of opinion that ''hypoxantha from the Nile Province of the Uganda Protectorate is identical with the form of C. brachyptera, occnrrmg in the Sudan", and that "C rufa is a West African bird found from the Welle river to the Cameroon and perhaps Angola". I have therefore given the Elgon specimens the above name. V. Someren gives 42 mm. as the wing-measurement of a specimen from Moroto, Turkanaland (Journ. E. Afr. Mg. N, H. Soc, 1921, No. 16, p. 26).

This form o( hypoxantha is described from Changamwe (near Mombasa) and distinctly differs from the preceding in being considerably paler, predominantly greyish, on the back, on account of which the more or less dark-brown colour of the head contrasts with the rest of the upper surface. In the pre- ceding torm the colour of the head and back was the same. — 238 — Mearn s also mentions that it is „l(3ss distinctly streaked above", but in this I cannot agree, inasmucli as these two are almost more distinctly streaked above, which I dare say is due to the fact that both specimens are in moult and the old feat- hers thus paler and more abraded on the edges, whereby the centre of the feathers appear darker.

But the boundary towards the east should be moved to the regions of Kenia, as v. S o m e r e n (Ibis, 1916, p. 456) has found the bird in the Nairobi district, jwhere the present specimen was also shot. This individual agrees splendidly with Sclater and M.- Praed's description and has the wing 60 mm., tarsus 24 mm. Irides, bill and legs as in the preceding.

Lake Naiwasha. Amongst the thick reeds in Lake Naiwasha this songster was tolerably common. As a rule it frequented the outskirts of the reed-belt, where it was extremely difficult to detect, but I often heard its song from some little clump of reeds out in the water, which mostly recalled the song of the the song-thrush. When I came too close to it it flew a little distance along the surface of the water to the shelter of the nearest reed-bed. Here it at once began singing, nimbly hopping from stalk to stalk or climbing up and down the reeds. But it always kept to the lower end of the reeds, where it was well hidden and it was only incidentally that I caught a glimpse of it. The plumage of tlie old birds agrees with Neumann's description (Nov. Zool., vol. XV, 1908, p. 247) but my younger specimens are, as a rule, somewhat darker above than the old birds. 239 According toReichenow (op. cit.) the tibias are 'Muster- braun".

It frequented the withered, small bushes on the outskirts of the forest at an altitude of about 8.000 feet. At Elgon I saw the bird a few times and always on the fringe of the bamboo-zone at an altitude of 9. 500— 10.000 feet. Here among the old, biowuish yellow bamboo-straw it was very difficult to detect, v. S o m e r e n says, that he has only seen it in the reed beds of swamps and rivers (Nov. Zool. XXV, 1918, p. 288), but on the eastern slopes of Elgon I only saw it in the higher regions in the above-mentioned localities. Neumann has dwelt with B. cinnamomeus and B. c. sal- vadorii Neum. in detail (Oin. Monatsber., 1903, p. 90—91) and says that the S clioa • cinnanwmevs is larger than the East African salvadoiii but the diifereuces in other respects between them are not great. The former measures: cf wing 67 mm., tail 77 uim.; 9 65 mm., 69 mm. The latter: cf 63 mm., 70 mm.; 9 60 mm., 65 mm. V. S 0 m e r e n has (in agreement with Hartert) given his Elgon specimens the style of salvadorii, although they have a wing-measurement of 65—68 mm., and the tail is much darker — 240 — and he adds that "these birds are quite distinct from B. cinna- momeus from Kikuyu and Mau". But Neumann's specimens originate from the Gurui Mountains in German East Africa and the author says that bet- ween these birds and those from Mau there is a considerable difference, whence they might possibly be a distinct intermediate form. Now, as Elgon specimens in their turn, according to v. Someren, are quite distinct from the latter there should thus be two good forms besides salvadorii. I have made the same observations as v. Someren, i. e, that the Elgon specimens have a much darker tail (dark-brown) than that from Londiani (not far from the Mau mountains) for in the latter specimen the tail is rusty-brown. Neumann (op. cit.) states that all the specimens examined by him were different from each other, and under these circumstances it seems to me to be audacious to advance these probable individual differences as characters for the different forms. I assume, however, that the author's description of his own form is correct, and although the measurements for the wing of female specimens agree more with salvadorii, and that of male-speci- mens with the one form just as well as the other, the measurements of the length of the tail approach those of cinnamomeus, and so I have called my specimens with that name. The young bird's plumage differs greatly from that of the adults. The head is dark greyish brown and the whole of the upper surface dark-brown without the rusty-red wash found in the adult. The throat and sides of the head are olive-grey with dark streaks and the lower surface, otherwise olive-yellow, olive- brown along the tlanks. Upper mandible dark brownish grey, lower mandible brown- ish yellow. Wing, tarsus, tail, 65 mm. 24 mm. 76 ram. cf Elgon. 61 mm. 23 mm. 68 mm. Q 63 mm. 23 mm. 71 mm. 9 E6ndiani.

They generally frequented the branches of the bushes but I often saw them in the tops of the trees, where they jumped from branch to branch and their behaviour was much asLonnberg has described it (Birds coll. Sw. Zool. Exp. to B. E. A., 1911, p. 123). On Elgon the bird was common right up to about 8.000 feet. I came across this bird's nest on two occasions. The first time was on the 21st of June at the foot of Elgon, about 6.500 feet above sea-level. The nest was found among the grass and flowers of the undergrowth of an acacia-forest, and unless the bird itself had risen and thus revealed the nesting-place, I should certainly not have discovered it. It was built in a plant, about 72 a metre in height, belonging to the family Verticillatae, about 40 cm. above the ground. The nest itself was suspended within three large green leaves, two of which — those at the sides — were sewn onto the nest by means of fine threads of grass. The third leaf ran out a little above the top of the nest, one end being bent downwards while the other end was sewn to the favther edge of the nest. It is evident from the above that this latter leaf does not assist in holding up the nest, for in that case it would doubtlessly get severed at the attached end by any violent movement of the nest, as for instance when the birds flew to or from the nest. As the nest is bottle-shaped, thus having the opening at the top, this leaf protects the entrance-hole and the nest itself from rain and wet, which instead of getting into the nest runs along the downward-bent leaf and falls to the ground. This nest was 80 mm. deep and 65 mm. wide at the bottom. At the top it was about 40 mm. wide and the opening itself was 38 mm. across. The materials of the nest were composed of only narrow thin fibres and dry grass-blades, loosely and flim- sily plaited together into a disorderly mass. The nest contained oae newly hatched young bird and an addled egg. The latter measured 15.5 X 12.2 mm. and weighed 87 mg. The colour is faint bluish green with large, brown spots spread all over the shell. The superficial spots are dark-brown and of a smaller size. The different spots are most strongly marked at the thick end and here are also diffused brown-lilac spots mingled with small black points. Both male and female incubate, but on most of the occasions when I beat up the in- cubating bird it was the male that left the nest. The second nest was found on the 24th July, below the slopes of Elgon. It was built something like the former and in the same sort of locality and contained 3 newly hatched young. If we read through the literature of the last decade about JBrinia mysiacea we shall find that the opinions concerning the 16 — 242 — different forms belonginp to this species diHer very much, but agree in this respect, that it is extremely difficult to determine the various forms. Neumann asks the question as to whether there are probably two simihir species occurring together: nnjstacea and murina, as H e u g 1 i n presumes is the case in Nord-east Africa (Journ. f. Orn., 1906, p. 277). Zedlitz does not consider it probable that one darker, larger form and another lighter, smaller form occur together, but combines these two into one common form. He suminarizes his investigation under three heads: 1. cfcT and 99 ^^ "ot differ essentially in measurements; 2 dark and light sjjecimens are found of both sexes; 3. the breast-patch, as a rule, is not found in 9^ do^ always in cf. These results are — as far as I can find — quite correct and in the sories of 20 sj)ecimens I have before nie there is every possible, both gieat and little, individual variation represented. S c 1 a t e r and M. - P r a e d (Ibis, 1918, p 676—677) were however the first to deal exhaustively with the different forms of mystacea and they have separated four. According to these writers the form occuring in East Africa and Uganda is named P. mystacea tenella Cab., which is larger than — otherwise very similar to — melanorhyncha from West Africa. The wing-measurement for tenella is 48 — 55 mm. V. Someren has, however, described a new form: immu- tabilis, which differs from tenella (which is a coastal bird) in being "considerably larger and much darker. Further, it lacks the wide white supercilium found in tenella. Wings 53 — 57 mm. It ranges from Ukamba in East Africa to Uganda (not including the S. Ankola River destrict)". If the wing-measurement of tenella amounts to 55 mm. and the maximum for immutahilis is 57 mm. then the difference is by no means "considerable", and specimens of both forms reaching 55 mm. or less must then be distinguished by means of the other distinctive features. With reference to the lack of the wide supercilium in immutahilis, and even if he had not done so, we should of course, judging from the locality from which they ori- ginate, refer these individuals to the above-mentioned form. Only 2 cf specimens attain the maximum for the wing of tenella^ all the others fall short, as appears from the following table: Wing, tarsus, 50 mm. 20 mm. cf Ngong. 51, 51, 52.5 mm 21 — 22 mm cTcT Kiambu. 54 mm. 21 5 mm. cf Naiwasha. 51, 53, 54, 54, 54, 54, 55, 55 mm. 21—22 mm. cTcT Elgou. 53 mm. 20 mm. cf Eldoret. 50, 51, 53 mm. 20—21 mm. 99 Elgon. 49, 49, 50 mm. 20 mm. 99 Eldoret. — 243 — V. S 0 m e r e n says further of this form that "the wing- feathers are more edged with brownish". This seems also to agree on the whole, although one or two have the wing-feathers edged with greyish. Reichenow points out (Vog. Afr. Ill, p. 591) that the females of Frinia mystacca are distinguished by the yellowish tint on the upper parts of the body and in being smaller than the males. This agrees perfectly with the 6 females before me, the lower surface of which shades more into yellowish brown than pure yellow, all of them have a clear yellowish wash on the lower surface as well. The females dififer, further, from the males in the colour of the bill, for the latter have the bill en- tirely black (in the juvenile dark greyish brown) while the females on the other hand have the upper mandible horn-brown, the lower mandible brownish yellow with a dark tip. Irides light-brown — brownish yellow; bill see above; legs pale flesh-coloured — faint brownish yellow. Apalis cinerea cinerea (Sharpe). — Rchw. III. p. 604. 1 (5 ad. 4. 7. Mount Elgon. Only observed a few times in the depths of the forests on the eastern slo|)es of Elgon. The specimen is in a dress that agrees very well with S h a r p e's description (Ibis, 1991, p. 120). Re i c h e n o w (op. cit.) gives the wing-measurement as 53 — 55 ram., but in the ori- ginal description of specimens from Elgon the length of wing is given as 2 25 inches, i. e. 57.14 mm. The present specimen, which thus originates from the "terra typica", has the following measurements: Wing 58 mm.; tarsus 21 mm. Irides reddish brown; bill black; legs brownish yellow. j Apalis cinerea minor Granvik. 1 (5 ad. 18. 4.; 1 g ad. 18. 4. Kiambu. In the Nairobi districts this bird was not rare. This form of cinerea differs from the typical one in being considerably smaller and recalls sclateri (Alex.) very forcibly, the lower sur- face being a deeper yellow. Even the chin and throat are more strongly yellow. Besides, the head is darker brown and the front part of the back darker grey than in the typical Elgon form. Wing, tarsus, 52 mm. 19 mm. cf 49 mm. 18 mm. 9 Irides, bill and legs as in the preceding. 16* -_ 244 - This form very closely resembles the specimens of A. hrunnei- ceps Rchw. in the Berlin Museum, but the latter are larger : Wing 54 mm., tarsus 200 mm., and not so yellow below as the Kiambu specimens. Apalis tnelanocephala nigrodorsalis Granvik. 1 c5 ad. 19. 9. Kiambu. This new form of tnelanocephala was shot in the vicinity of Nairobi, in the same forest-area in which A. cinerea minor was shot in the month of April. I only saw it on one occasion and then 3 individuals were together. They frequented the highest branches of the trees where they were difficult to detect. One more specimen was shot, exactly like this one in colour, but it was so badly damaged that it could not be kept. This form differs from melanocephala in being black on the whole of the upper parts, of the same colour as the head. It is also considerably larger. Prof. 0. Neumann, who has seen my specimen, is of the same opinion as I am, that it is a good representative of a good, new form and has kindly placed at my disposal the following comparative list from his yet unpublished work: Specimens from South Somaliland measure: 1. cT Tot. length 115 mm.; wing 49 mm ; tarsus 17 mm.; tail 60 mm. ,, 47.5 mm ; tail 59 mm. „ 47 mm.; „ 59 mm. ,, 48 mm.; „ 62 mm. „ 47 mm.; „ 62 mm. „ 43 mm. ; „ 47 mm. ,, 45 mm.; „ 47 mm, ,, 44 mm.; „ 50 mm.

In the forest under-growth on the eastern slopes of Elgon this form was fairly common and was found up to about 7000 feet above sea-level. Zedlitz has dealt in a excellent manner with the genus Camaroptera (Journ. f. Orn., 1911, p. 328—345) and has proved that the East African form of this large "form-circle" of griseo- viridis is griseigula. The northern range of this form should go by Victoria Nyanza. But the Elgon specimens agree perfectly with those from the Kikuyu-country, which in turn coincide with Zedlitz's description oi griseigula^ whence the northern range extends to Elgon. V. Someren gives his specimens from West-Elgon only the style of griseoviridis (Nov. Zool., XXV, 1918, p. 289) but, on the other band, be names those from the Kikuyu-country — 246 — griseigularis, which is probably a slip of the pen, for the name should be griseigula.

Monatsber., 1906, p. 7) he described a new form: kikuyuensis from East Africa, and yet another from Senegal: — 247 - permistus (Orn. Monatsber., 1906, p. 146). Moreover, Reiche- n 0 w has described one from Adamaua, gularis (Orn. Monatsber., 1910, p. 7) and another from A.madi (by Uelle in the Congo), hypohrunneus (Journ. f. Orn., 1915, p. 129) But Neumann includes two more new forms in the circle, platycircus Sws, and iogoensis, thus we have to reckon with at least 13 allied forms. Opinions concerning these forms are so widely different, that there can be no question of discussing all of them here. Reichenow (Journ. f. Orn., 1918, p. 106), for instance, con- siders Tcilcuyuensis synonymous with hypostictus and according to Og. -Grant (Zool. Res Ruw. Exp., 1910, p 377) kirki coin- cides with the latter. But Reichenow points out that hypo- stictus, which in Vog. Afr. Ill, p. 660 he makes a synonym of emini, is an East African bird, occurring also in Angola, while kirki is found in Nyanza and the Sambesi regions (Vogelf. Mittelafr. Seengeb , 1912, p 366) Meumann again considers that kikuyuensis is a mountain form, restricted to the Kikuyu country, while not far from there, west of the Massai graves, occurs cinereus and at Lake Naiwasha to the north-east emini. Thus, three diflFerert forms within a rather small area of British East Africa. It is not easy to form a definite opinion as to the different forms and their distribution and this "form -circle" therefore seems to stand in need of a further careful, reducing revision. I have, however, compared ray specimen with those in the Berlin Museum and found that it agrees entirely with those bearing the name of hypostictus there, therefore I give it this name for the present. Neumann's character for this form is, that the tail is distinctly furnished with transverse bands (Journ. f. Ornith., 1904, p. 549), but the specimens of kirki found in Berlin have these transverse bands as well. In my specimen these bands are cer- tainly not distinct, but are nevertheless visible. The lower sur- face is pale-brown with a rusty-brown wash. Wing 105 mm.; culmen 21 mm.; tarsus 34 mm. Irides yellowish white; bill black, legs dark-grey (almost black).

Mount Elgon. In the acacia- country and scrub below the eastern slopes of Mount Elgon this race was very common. It always appeared in small flocks of 4 — 5 in number — probably in families, as out of such a flock I once shot four, three of which were young birds and the four.th an adult. — and at times they associated with Eurystomus afer rufohuccalis. — 248 — They are not very shy (Bohni, according to Re ichenow, considers them to be very shy) and in their behavoii they recall our own Turdus pilaris in many respects. The plumage of the adult birds agree very well with Rei- chenow's description. Still, one cf specimen has a brownish patch on the fore -neck, another has such a one on the right side of the body. The lower surface is in general a uniform greyish brown. In one 9 specimen there is, however, a sug- gestion of dark shaft- spots on the feathers, which is otherwise a characteristic of the following form. The young birds are all predominantly brownish above, thus recalling melanops, and the feathers have not the light fringes found in the adults, which give them a highly aberrant appear- ance. The throat is more whitish (in the adults grey). Breast and belly are mainly grey; flanks, crissum and tibia brownish yellow (in the adults grey — faint greyish brown).

"darker grey on the upper and lower surface, and the feathers of the breast and abdomen have dark centres". The throat is whitish grey with dark shaft-spots to the tips of the feathers. v. Someren gives the wing to 115 — 1 30 mm., and al- though the specimen before me does not reach the minimum, but agrees in other respects with the above description and also originates from the "terra typica", there is no doubt that it should be referred to this form.

The first specimen of this bird was shot in a grove or park situated close to Kikuyu Railway Station. In the districts of Londiani this Thrush was common and occurred both in the interior of the forests and on the bushy fringes thereof. On the eastern slopes of Elgon I saw the race several times and always in the middle of the forests among the entangling thickets, where it was difficult to get within range. It occurred on Elgon as far up |as 11.000 feet, where one specimen was shot, in the company of Tarsiger elgonensis. Lonnberg says of this bird (Birds coll. Sw. Zool. Exp. B. E. A., 1911, p. 126) "that its distribution resembles that of Turacus hartlaubi'\ which should be true. He has also found a great difference, with reference to the colour of the lower parts, between specimens from Kenia and the Escarpment, and those originating from Kilimanjaro, the former being "more vi- vidly coloured with a rich rusty red". I have myself made the same observation, the Kikuyu- specimen being paler and also having the throat and fore-neck with a reddish brown wash (all the feathers being fringed with reddish brown). Likewise, the whole of the upper surface has a dark brownish red hue. In all probability this bird is only an occasional variation, although the difference from the others is so great and conspicuous that I was tempted to believe that the birds of the Kikuyu-country — provided it could be confir- med that they resemble this specimen — represented a distinct form.

In the scrub below the eastern slopes of Kigon, outside one of the large caves found here and there, ureat numbers of Hyrax were found among the piled-up rocks and stones. While I lay wai- ting to get a shot at these animals there suddenly flew out of a crevice between two large rocks a female Thamnolaea sub- rufipennis and began to run and hop about the stones in an agitated manner. With tail uect and drooping wings it ran back and foie but soon disappeared into the same crevice, from which on later occasions some Eyrax appeared. The bird bad its nest in an inaccessible position under the large rocks and could reach the nest by different ways, in which I heard the nestling twittering. The female was in moult and this is the second case I have met with out here of a nesting bird changing its dress (vide Centropus senegalensis incertus). The specimen differs somewhat from Reich enow 's description (op. cit.) in the feathers of the throat and neck being greyish black with rust- brown tips, becoming lighter towards the chin.

This bird, common everywhere, was met with both in the open grass-countiy and in the acacia areas and it was very abun- dant in the bush country below the eastern slopes of KIgon. In the series of 11 skins brought home there are scarcely two which are alike. Thus, those from the Kikuyu- country (Kiambu) are dark blackish brown above and below, and I cannot discern any difference in the tint. These, then, seem to be true cryptoleuca. Those from Eldoret are considerably lighter and — 251 - have hardly any black in the dark-brown plumage, while those from Elgon have the head blackish brown, the rest of the body dark-brown. The young birds from Elgon are entirely black (not blackish brown) and only the upper wing-coverts are edged with brown. The feathers of the throat lack the pale brown tips, found in the old birds. In the original description of this form (Ibis, 1891, p. 445) the tarsus is given as 1.3 ins (= 33 mm.); Reichenow (op. cit.) on the other hand, gives 34— 3&mm.

When I compared my specimens with true aethiops in the Berlin Museum, it appeared that my cryptoltuca were, as a rule, considerably darker and thus any difference in this respect between these two races cannot be made the cause for a sepa- ration of the West African from the East African. Prof, 0. N e u - m a n n , who has examined a great number of both races, kindly placed his notes at my disposal and from his investigations it appears that "the black and white of the wings is more sharply defined in the Senegal bird {aethiops) than in the eastern bird (cryptoleuca). The bill is always longer and slenderer in the eastern bird, shorter and stouter in the Senegal bird", which agrees perfectly with all my specimens. Finarochroa sordida rudolphi Mad. — Orn. Monatsber., 1912, p. 175. 6 (5(5 ad. 28. 6.-30. 6.; 3 CQ ad. 28. 6.-30. 6.; 2 $6 juv. 28. 6.-29. 6.; 4 2Q juv. 28.6.-30. 6.; Mount Elgon. This form, described from Elgon, is a pure bird of the mountains which first begins to appear north of the E'nca-forest. Here large, desolate grass areas extend upwards, where solitary Composi^ae-plants in the form of shrub and several other plants constitute the principal vegetation. Here and there small streams flow along and on their banks the vegetation is richer. Every- where there lay larger or smaller accumulations of rocks and stones and it is mainly in the vicinity of these that this bird is — 252 — met with very commonly. The vertical southern range, on the eastern slopes of Elgon, seems to be about 12.000 feet above sea-level and the bird occurs right up to 14.000 feet level, i. e. up to the summit of Elgon. At the time — the end of June — when I visited these regions this Stone Chat was almost always seen in small tiocks of 4 — 5 in number and when alarmed they alighted just as often on the branches of the small bushes as on the stones or rocks. They were not very shy, and I could get very near them before they took wing. Neumann separates six forms belonging to this species (Journ. f. Orn., 1906, pp. 290—293) but also combines the Elgon form under ernesti, to which M a d a r a s z , however, has given the name of rudolphi (Orn. Monatsber., 1912, p. 175). Thus, we have at least 7 forms to reckon with. M a d a r a s z characterises this form, by showing that it is smaller than the Kilimanjaro-form hypospodida (to which form R e i c h e n 0 w : Vog. Afr. Ill, p. 714, before M a d a r a s z described it, refers Elgon specimens). S j o s t e d t gives the wing-measurement for hypospodida from Kilimanjaro as 70 — 80 mm. (Wiss. Erg. Schw. Zool. Exp. Kilimanjaro-Meru 1905—1906, Stockholm 1910, p. 168). As appears from the table below the difference in size is null or very slight. On the other hand, the other distinguishing features are good, i. e. lower surface with strong brown wash; the black-brown band on the outer tail-feathers narrower. According to Madarasz the wing is 71 — 74 mm., the tarsus 28 — 30 mm. Neumann has measured three Elgon-specimens and gives 75—79 mm. as the wing-length. In the series of 15 specimens before me it appears that the adult specimens have a very dark- brown upper surface, while that of the young birds is blackish brown. The three outer tail-feathers are white with narrow blackish brown tips. The fourth rectrix is, as a rule, white on the upper four-fifths of the outer web, otherwise blackish brown. St)metimes the white extends a little on to the inner web. Further, in the young birds the feathers of the lower sur- face are tipped with dark-brown, so that the lower parts look as if they were furnished with uneven undulations. Moreover, the wing-coverts and primaries are furnished with broad rust- brown edges and tips.

At Kendu this bird was rather common and frequented the withered grass-plains in the vicinity of a native village, in the same localty as that in which Fyrrhulauda leucopareia occurred. Zedlitz (Journ. f. Orn., 1916, p. 105) mentions under pileata a cT- specimen from Kismaju (north-east British East Africa) with a wing-measurement of 96 mm., and quotes Neu- mann's opinion (Journ. f. Orn., 1900, p. 313) that the true South Africa pileata is represented in Central and southern German East Africa by the smaller and darker livingstonei Tristr., and in north-eastern German East Africa by alhinotata Neum., which is distinguished by the white tips to the tail-feathers. — Zedlitz does not, however, consider this character to be any systematic distinction but only an attribute of the entirely fresh plumage. It is remarkable that Ogilvie-Grant calls his specimens from Bechuanaland (Okwa, Lehutitu) livingstonei and says of them that they are distinguished from typical pileata by "their smaller size and shorter bill". Further, the same writer points out that Livingstone's VVheatear is "found throughout the Kalahary wherever open country, such as it loves, was met with". If it is proved that South Africans, as a rule, have such a high figure for the wing-measurements as Neumann states: 93 — 95 mm., and East African specimens keep about the figure attained by mine, there should surely be good reason for sepa- rating them. But as Zedlitz' specimen from the coasts ex- hibits a wing-measurement of 96 mm., it should undoubtedly be a good pileata, as the author himself thinks, and the South African form thus be the coastal form in British East Africa, while those from the interior parts of the country should belong to livingstonei. Mack wort h-Praed gives the wing for a specimen from the Tsavo-River at 88 mm. and styles it pileata (Ibis, 1917, p. 382). Banner man also mentions pileata for the first time from Mombasa, but does not give any figures (Ibis, 1910, p. 695). Stone names his specimens from Naiwasha, livingstonei (Proc. Acad. Nat. Sc. Philad., 1905, p. 771) and states that "they are much greyer on the back than the South African bird, C. pileata, and he also separates alhinotata from livingstonei. The present specimens have the following measurements: Wing, tarsus, 89 mm. 30 mm. cf. 84 mm. 29 mm. 9- — 254 — Both specimens are dark -brown on the upper surface — head brownish black — and in cT the nape shades somewhat into grey. In other respects they agree with Reich enow's de- scription. Irides dark-brown; bill and legs black. Saxicola torquata salax Verr. — Journ. f. Orn., 1910, p. 176. Saxicola salax Verr. v.

At all places where our expedition stayed this Stone-chat was one of the commonest birds, being found in the glades and on the fringes of the forests. In the neighbourhood of Londiani on the 8th May I found a nest of this bird in a forest glade, overjirown with short grass. It lay on the edge of a tuft, hidden in the grass. It measured 110 mm. in diameter and was 80 mm. high. The inner frame- work measured 60 cm. The nesting material was composed, for the most part, of brown, dry straw and hair. The nest was sparingly lined with tufts of hair: Even thin roots of plants formed part of the outer bowl. The eggs were newly-laid and were three in number: 1. 20.2 X 13 5 mm. 90 mg. 2. 20 X 132 mm 90 mg. 3. 18.6 X 13.3 mm. 89 rag. In colour and size they resemble much the' eggs of Pra- tincola rubetra. The ground colour of the shell is dirty-green with small, fine reddish-brown spots over the whole of the sur- face, forming a kind of calotte at the thick end of one of the eggs. Hartert has (Journ. f. Orn. 1910, p. 176-177) dealt with the genus Pratincola in detail, and among other things separated salax (West Africa) and axillaris (East Africa). In my large series of 29 specimens all have the inner-web of the wing dark-brown — li^'ht- brown. Not a single one has a white inner-web like salax (according to Hartert). R c i c h e u o w (Vogeif. Mittelafr. Seengeb , 1912, p. 369), however, mentions that in East African specimens he has also found a white inner-web, and therefore cannot ascribe to this difference no more than to the other differences given by Hartert any systematic value. — 255 — On this account he styles both the East African and West African specimens salax. This opinion is also shared by Lonnberg (Arkiv for Zool., Band II, No. 3, 1917). With regard to the extent of the reddish-brown patch on the fore-neck Reichenow finds no difference between East and West Africans although H a r t e r t says that in salax it is 2 — 3 cm. wide, but in axillaris only 1 — IV* cm. In this I agree with Reichenow. Ogilvic-Graut (Zool. Res. Ruw. Exp., 1910, pp. 375— 376) has already pointed out how this reddish brown band "varies greatly in extent in different individuals, quite irrespective of season", and the different instances he gives, along with a few others, are represented in the present series of 16 cfcT (see Plate). Lonnberg also mentions the same thing (op. cit.). The most interesting are those which 0-G r an t correctly names "quite young males in first plumage". In these the reddish brown band is in some cases as wide as 15 cm. and besides, the lower surface is more or less brown-spotted. Further, in one of them the black feathers of the throat are tipped with brown, as well as the feathers of the upper surface — from the forehead to the upper wing-coverts. Even 99 ^ai^y somewhat. In general the fore-ueck is a deeper reddish-brown than the rest of the lower surface, but in some the whole of lower parts are of the same dark colour as the fore-neck. That salax and axillaris are really two good forms, seems to me doubtful. I have examined and measured 12 cfcT and 9 99 ^""om the collection at the Berlin iMuseum procured from different parts of East Africa, and among these there are indi- viduals with a white inner-web to the wings, others with brown, and as the reddish-brown patch of the fore-neck is not of any systematic value, I have, in the same manner as Re i c h e n o w. Grote, Lonnberg, Ogilvie -Grant and others, called my specimens salax. Wing, Tarsus, 70, 74, 69, 70, 70, 7 1 , 68, 68 mm. 22 - 23 mm. cTcT ad. Ngong, Nai- washa, Kikuyu. 70, 71 mm. 22—23 mm. cfcT ad.

The throat is whitish grey (in pyrrhopterus, brownish). The lower surface is wholly grey in the Elgon specimen, the lower parts of the fianks with an olive-brown wash (in p. pyr- rhopterus the upper parts are distinctly olive-brown). The under tail-coverts are greyish brown ; in pyrrhopterus reddish brown. The head is olive-brown with a greyish tint. They differ from p. pyrrhopterus also in being considerably larger.

But the dif- ferences between his type (in Berlin) and mine, with reference to the dress and, not the least, as regards the size, are so con- siderable, that I have given the Elgon bird a new name. If p. tanganjicae is a good form, then mine approaches that form, but the head is not predominantly grey as in the former, nor do the measurements coincide. The type cT of tan- ganjicae measures 72 mm. in the wing, and four other specimens — 257 — in Berlin have the following measurements: cT, 69 mm.; 99» ^6, 67, 69 mm. Alcippe ahyssinica ahyssinica Riipp. — Rchw. III. p. 741. 1 (5 ad. 10. 7. Mount Elgon. This bird inhabits the same kind of locality as the prece- ding and is therefore very difficult to detect.

Like some of those mentioned previously he sings even after nightfall. Wing 69 mm.; tarsus 23 mm. Irides dark red; bill dark greyish brown; legs bluish grey.

It was found on Elgon up to an altitude of 8500 feet. Schuster has described this bird's song very carefully and also gives some information about the occurrence of the bird. In the present series there are no great differences. Younger birds are more olive-brown above than older, which are predo- minantly slate-grey.

The specimen before me is in many respects like C. heug- lini subrufescens, but in some respects it recalls donaldsoni. Thus, the upper surface is dark slaty grey without the slightest trace of olive-brown (approaching the latter form). Further, the central tail-feathers are black and the outer-web of the outer tail feathers blackish, much the same as in subrufescens, but in contradistinction to the latter the next three consecutive tail-feathers are also furnished with black edges on the outer- web, the fifth is entirely black with rusty-brown streaks along the shaft. I have compared my specimen with the subrufescens specimens in the Berlin Museum but have not found any which resemble mine in the uniform grey tint of the back. It is possible that mine is only an aberrant bird of subrufescens, which, according to Reichenow (op. cit.) were shot in the Nairobi district, and therefore I have not given it a new name.

Someren (Nov. Zool., vol. XXV, 1918, p. 290) says of this form that it differs from other closely related forms „by the absence of an yellow on the tail-feather". But this is not correct, for the original description says that „the outer tail- feathers are black except at the extreme base, which is yellow", and my specimen agrees with that description. On the other hand I agree that the white spot above and in front of the eye extends almost from the nostril to the posterior angle of the eye. Wing, tarsus 85 mm. 27 mm. Irides brown, bill black; legs greyish green. List of Works referred to. Alexander, Boyd ... ..... Exhibition of eight new species of African birds. [Caprimulgus chadensis.) Bull. Brit. Orn.
