DAS GENUS GRACULA LINN. ') UND SEINE ARTEN NEBST BESCHREIBUNG EINER NEUEN ART

Dr. O. FINSCH.

(Tafel 1 unci 2).

Das hervorragendste Kennzeicheu der Arten dieser Gattung bilden zwei unterhalb des Hinterkopfes entspringende, horizontal hervorstehende, blattförmige, lleischige Nacken- lappen , deren Form und Grosse am besten durch die bei- gegebenen Abbildungen veranschaulicht wird, soweit dies nach ausgestopften Exemplaren oder Balgen möglich ist. Dasselbe gilt in Bezug auf den nackten Fleck unter dem Auge , der durch die Art der Preparation haufig verzerrt und verschoben wird , so dass sich die ursprüngliche Form dieses Hautfleckes, sowie die Ausdehnung des hinter deui- selben sich anschliessenden Federfeldes nicht immer so getreu wiedergeben lasst als nach dem Leben. Der nackte Haut- fleck unter dem Auge fehlt übrigens bei einer Art [ptilo- genys^ N". 10) ganz. Bei jungen Vögeln sind die Nacken- lappen mehr oder minder rudimentar, zuweilen nur eine Hautfalte (s. Fig. A) und selbst diese fehlt sogar an einem

1) Siehe Salvador! (Annali del Mus. Civ. di Genova, 1893, p. 137, Note) der nacliweist, dass Linnés Gattung -Gracula", trotz der verschiedendsten unter diesem Namen eingereihten Arten (die ganz anderen Genera angehören), auf G. religiosa begründet wurde und deshalb erhalten bleiben muss. Uebrigens giebt auch Wagler (Syst. av. 1827) eine trefiiiche Beschreibung des Genus Gracula (Typus mG. religiosa Wagl." = javanensis Osbeck).

alten Vogel unseres Museums ganzlich (s. G. javanensis , M. S. Cat. N^ 38).

Die Nackeulappen, wie der nackte Fleck unter dem Auge, Schnabel und Füsse, sind iin Lebeo sehr lebhaft (gelb, orange bis rotb) gefarbt. Icli verzicbte aber die hierauf bezüglicben Notizeu wiederzugeben, weil dieselben zu zahl- reich sind , sich überdies zuweilen wiedersprechen und ver- weise auf die von Schlegel gegebene gute Farbentafel (Nederl. Tijdschr. voor de Dierk. I, 1863, PI. I).

Der Leibesgestalt nach sind die Lappenatzeln ') kurze, gedrungene, dicke Vogel, die unter der Staarenfamilie mit zu den grössten geboren , und sich durch das einfarbig schwarze Gefieder mit lebhaft purpurviolettem oder stahl- grünem Metalschimmer kennzeichnen, das nur durch einen weisseu Flügelspiegel (meist auf den Handschwingen) un- terbrochen wird.

Die Form des sehr kraftigen Schnabels ist aus den beige- gebeneu Abbildungen ersichtlich , welche zugleich die kleinen rundlicheu , freisteheuden Nasenlöcher zeigen.

Die Flügel sind lang , spitz und decken den Schwanz bis über die Halfte oder nahezu auf Zweidrittel. Die Flügel- spitze ist massig lang und betragt meist etwas weniger als ^4 der ganzen Flügellange. Handschwingen sind 10, Arm- schwingen 8 bis 9 vorhandeu (je nachdem man die letzte kleinste mitrechuet, was bei Balgen und ohne Gefahrdung derselben sich ohnehin schwer genau feststellen lasst). Be- merkenswerth für die Flügelbildung ist die Verschmalerung der zweiteu Schwinge an der Innenfahne fast von der Mitte an, und die, wie bei allen staarartigen Vögeln, rudimen- tare erste Schwinge, welche nur wenig langer ist als die oberen Deckfedern der Handschwingen und wegen ihrer Kleinheit leicht übersehen werden kann. Die Lange der ersten rudimentareu Schwinge variirt bei 30 Exemplaren

1) In Indien heissen diese Vögcl meist: «Myna, Mino oder Maina", ein Name der auch auf andere staarartige Vogel der Gattung Acridot/ieres ange- wendet wird, der malayische Name ist »Tjiong"; .Beo" ist der Battaname für G. javanetisis.

von G. javanensis von 25 35 ram. uud ist bei G. religiosa am kleinsten (15 20 ram.).

Ueber das Verhaltniss der laugsten Schwingen lasst sich kaum eine allgemein guitige Formel aufstellen , da indivi- duell bei ein uud derselbeu Art erhebliche Abweichuugen vorkommen , wie dies bei so vielen Vögeln der Fall ist.

Die Untersuchung von '60 G. javanensis mit vollkommen entwickelten Schwingen ergab folgeude Verhaltnisse :

1 Exempl. : 6*^ Schwiuge die langste ; 5 u. 4 wenig kürzer, 2^6.

Die letztere Formel is daher am haufigsten vertreten , auch bei den übrigen untersuchten KYten: religiosa, venerata (hier auch 6 u. 3 6), intermedia, ptilogenys. Bei G. ro- busta fand ich dagegen vorherrschend die 4 u. 5 Schwinge am langsten (3 und 6 kaum kürzer ; 2 =: 7), bei G. batuensis meist die 4te; (3 u. 5*^ wenig kürzer, 2te = 6ten).

Der Schwanz ist kurz (stets kürzer als die Halfte der Flügellange), am Ende gerade oder sehr wenig gerundet und besteht aus 12 brei ten , am Ende abgestutzten Federn, die von den breiten Deckfedern mehr als über die Halfte bedeckt werden.

Die Füsse sind sehr kraftig, der Lauf ist ungefahr so lang oder etwas langer als die Mundspalte oder die Mittel- zehe mit Nagel und vorn mit sechs Schildern bekleidet; die Zehen sind mit stark gekrüramten scharfen Krallen bewehrt , unter denen die der Hinterzehe am grössten ist.

Die Verbreitung der Lappenatzeln erstreckt sich über Vorder- und Hinterindien nördlich vom Himalaya, südlich bis auf Ceylon , die Andamanen , Nicobaren und Malacca, östlich bis in's westliche China, über die grossen Sunda-

iuselu , östlich bis auf die lusel Palawan, südlich auf einige zwischen Java und Timor gelegene Insein , von denen A.lor die südöstlicliste Grenze der Verbreitung bildet. (Siehe N". 2, G. venerata). Auf Timor selbst, Celebes und den Philip- piuen fehlen Lappenatzelu und sind (mit Ausnahme der ersteren Insel) durch verwaudte Gattungen {Basileornis ^ Sarcops) vertreten , ebenso auf Neu Guinea und einigen benachbarten Insein (durch die Gattungen Mino und Me- lanopyrrhus).

Bezüglich des Artenwerthes sind, wie fast stets in dieser Wissenschaft, die Ansichten der Forscher sehr verschieden. Schlegel characterisirte 1863 ') sieben Arten (da seine Gra- cula Dumonti (Less.) zum Genus Mino Less, gehort), Sharpe beschreibt im » Catalogue of the Birds in the British Museum" (vol. XIII, 1890, p. 98 110) 5 Species und 3 Subspecies, ausserdem 4 dem British Museum fehlende Arten , im Ganzen also 12 verschiedeue Formen. Seitdem sind zwei weitere hinzugekommen, so dass im Nachfolgenden 14 Arten cha- racterisirt werden , von denen nur 2 meiner autoptischen Untersuchung entgingen.

Ueber Lebensweise, Nestbau (stets in Baumhöhlen) und Eier besitzen wir von den indischen Arten eingehendere Kunde, wahrend über die der Sundaiuseln nur sparliche Notizen vorliegen. Das Gefangenleben schildert Brehm am besten (»Gefangene Vogel" 2te Band 2), 1876, S. 563 und 564).

Zweite bis 7^^ oder 8te Scbwinge mit weissem Spiegel (auf der zweiten nur auf der Innen- fabue, auf der acbten meist uur auf der Aussenfabne) der auf der fünften oder sechsten 20 28 mm. breit ist. Zuweilen zeigt die acbte Scbwinge nur einen kleinen weissen Fleck auf der Aussenfabne; ein Exemplar (M. S. Cat. N". 6, Flores) einen solchen aucb auf der neunten Scbwinge.

Die Anordnung der Nackttbeile ist wie bei G. religiosa (s. Fig. 1 und 2), indeui der nackte Hautstreif, welcber sicb bis zur Mitte des Hinterkopfes binziebt, ebenfalls am Innenrande einen aufrecbtstebenden (bis 5 mm. bohen) Kamm bildet, aber die Nackenlappen zeicbnen sicb durcb die bedeutende Grosse aus (bis 25 mm. lang und 30 mm. breit) und stossen an der inneren Basis zuweilen zusammen.

Alte Vogel stimmen in beiden Gescblecbtern durcbaus überein (aucb in der Grosse der Nackenlappen) ; Junge siud matter gefarbt und besitzen nur ganz kleine Nacken- lappen (M. S. Cat. N°. 2 nur 4 mm. lang) oder dieselben feblen ganz (Hartert) ; der weisse Spiegel zeigt dieselbe Ausdebnung als bei alten Vögeln.

Die Nackenlappeu siud an der iunern Basis (auf der Mitte des Hiuterkopfes) meist durch einen schraaleu Feder- streif geschieden ; die seitliche Basis zieht sich als schmaler Hautstreif bis fast zum oberen Augenrande bin.

Die beigegebenen Abbildungen (Fig. 5 7, Taf. 1) werden die erheblichen Abweichungen in der Grosse und Form der Nackenlappen besser zum Verstaudniss bringen als lange Beschreibuugen , indem sie aus einer Reihe von nabezu 50 alten Vögeln unseres Museums , die am meisten abwei- ch enden Exeraplare darstellen. Die Lange der Nackenlappen variirt, unabhaugig vom Geschlecht, wohl aber nach dem Alter, von 10 26 mm., die Breite von 13 18 mm., zeigt also in den Regel die Form eines mehr langen als breiten Blattes, wie dies Fig. 6 darstellt , die zugleich auch die vorherrschende Grosse zeigt. Der schmale Federstreif, welcher den inneren Basisrand der beiden Nackenlappen trennt, ist meist so schmal wie auf dieser Figur (6), zuweilen aber auch bis 10 mm. breit, also noch breiter als auf Fig. 7. Bei sehr alten Exemplaren berühren sich die Nackenlappen an der inneren Basis zuweilen (von 50 Exemplaren aber nur 15) oder sind hier selbst (ca. 4 ram. laug) miteinander verwachsen (wie Fig. 5), eiue Eigenthümlichkeit welche ich aber unter 50 Exemplaren nur an zweien fand.

heblicb (s. Fig. 3 und 4) und seine Grosse , wie die Aus- debnuDg des dazwischenliegenden Federstreifs werden bei Balgen sebr durcb die Art und Weise der Praparation be- einflusst.

In Bezug auf die Ausdehnung des weisseu Flügelspiegels ist nach der von mir untersucbten Reibe von 52 Exem- plaren das Folgende zu bemerken. In der Regel bescbrankt sich der weisse Spiegel auf die 2*^ bis 7*^ Schwinge (und zwar auf der zweiten stets nur auf die Innenfahne); 11 Exemplare baben aber auch auf der Si^en gcbwinge einen weissen Fleck , der aber nur bei einem Exemplare über beide Falinen lauft, bei den übrigen dagegen nur auf die Aussenfabne bescbrankt bleibt. Ein einziges Exemplar (M. S. Cat. N". 20 von Banka) zeigt aucb auf der Qt^n Scbwinge einen kleinen weissen Scbaftfleck. Die Brei te des weissen Fleckes auf der Aussenfabne der ö^en Scbwinge variirt in der Regel von 19 28 mm., nur drei Exemplare (M. S. Cat. N°. 28, 30 und 34: Padang) zeigen diesen Fleck nur 15 17 mm. breit, wahrend er bei einem Exemplare (M. S. Cat. N". 13: Borneo) sich auf 31 mm. ausdebnt.

lm Uebrigen ist die Farbung alter Vogel scbwarz rait lebbaft purpurviolettem Metallscbeine , der auf dem Bürzel, oberen Scbwanzdecken, Kopf, Bauch und den unteren Scbwanzdecken durcb einen dunkel stahlgrüuen Metallscbein ersetzt wird. Dieser grüne Schein ist zuweilen nur scbwacb angedeutet und ziebt mebr oder minder ins Purpurviolette, ja, drei Exemplare (M.S. Cat. N". 7 und 13: Borneo und N". 37: Malacca) zeigen auch auf Bürzel und den oberen Scbwanzdecken den purpurvioletten Schein fast so lebhaft als auf dem Mantel.

Junge Vogel siud mattschwarz gefarbt, namentlich auf der ünterseite; die Federn auf Kinn und Kehle sind kurz und zeigen hie und da die weisse Basis ; der weisse Flügelspiegel ist ebenso breit als bei alten Vögeln. Junge Vogel zeigen zuweilen die ausserste Schnabelspitze dunkel- braun oder braunlich getrübt und stets rudimentare (nur 4 5 mm. lange) Nackeulappen , die zuweilen nur eine

Junge Vogel in dem matt- schwarzeu Kleide und ohue Nackenlappen zeigen zuweilen die Plügel glanzend schwarz, die Oberseite mit purpur- violettem Scheine oder bie und da bereits einzelne metal- liscbglauzende (neue) Federn. Solcbe junge Vogel sind meist bereits so gross als alte, welcbe nacb unseren Keihen fol- gende Grössenunterscbiede zeigen :

Das letztere Exemplar von Salanga hat den Flügel auf- fallend kurz ^), aber drei alte Exemplare von Sumatra sind fast ebenso kurzflügelig (M.S. Cat. N». 30: Padang: 163 mm. ; N". 34: Padang: 165 mm.; N". 35: Deli : 163 mm.) und als Ausnahmen zu betrachten.

Die von mir notirten Verschiedenheiten in Farbung, Ausdehuung der Nackenlappen und Grosse sind unabhangig von den Localitaten, von welchen folgende in den Reihen unseres Museums vertreten sind: Java [Ost: Berg Kawi, Passaruan; West: Djassinga (S. Muller 1827), Gadok (Bernstein 1859), Berg Salak u. Preanger (Vorderman 1896)]; Borneo [Süden : Banjermassing (Schwaner 1843), Marta- pura (Croockewit 1852), Pleyhari (Semmeliuk 1866); Central : Obere Kapuas, Berg Keuepai (Büttikofer 1894); West: Pontianak (Moret 1894); Nord : Baram (Hose 1893)];

Ueber das Freileben dieser auf den Sunda-Inseln so haufigen Art liegen nur sehr spiirliche Beobachtungen vor. Dr. Hagen giebt einige kurze Notizen über Lebens- und Nistweise auf Sumatra ^) , berichtet aber sehr anziehend über das Gefangenleben und hauptsachlich über die Leich- tigkeit, mit welcher dieser Vogel menschliche Worte nach- zusprechen lernt.

Das ganzliche Febleu von Nackenlappen , die selbst junge G. Javanensis weuigstens durcb eine Hautfalte bereits andeuten, ist bei diesem alten Mauncben jedenfalls sehr auffallend, wabrscbeinlicb aber auf zurückgebliebene Ent- wickelung in Folge Gefangenschaft von friihester Jugend an zurückzuführen. Wenigstens wage ich es nicht das Exemplar als neue Art einzuführen.

Durchaus wie G. javanensis, aber der nackte Haut- streif , welcher die seitliche Basis der Nackenlappen bildet, zieht sich nicht bis zum oberen Rande des Auges und ist durch einen viel breiteren Federstreif von dem schmalen nackten Hautstreif uuter dem Auge getrennt.

Die Nackttheile stimmen daher gauz mit denen von G. robusta und G. batuensis überein (Taf. 2, Fig. 9 und 12), aber die Nackenlappen (16 mm. lang und 18 mm. breit) sind an der Basis nicht miteinander verwachsen, son- dern berühren sich nur, wie dies bei G. javanensis auch vorkommt.

Der weisse Spiegel findet sich auf der 2ten bis lOten Schwinge, auf der zweiten nur an der Innenfahne, auf der zehnten nur als Schaf tfleck auf der Aussenfahne und ist auf der siebenten 30 mm. breit.

Salvadori hat (1. c.) in Wort und Bild eine so treffliche Darstellung dieser ausgezeichneten Art gegeben , dass selbst der Mangel an Exemplaren kaum zu entschuldigen vermag wenn Sharpe dieselbe nur als eine Subspecies, und noch dazu von G. intermedia Hay, betrachten zu mussen glaubte, ein Irrthum der durch Oustalet (1. c.) bereits genügend klargestellt wurde, Nach sechs mir vorliegenden Exemplaren von Nias (Coll. Kannegieter 1895, s. Büttik. 1. c.) kann ich die von den beiden genannten Forschern augegebenen Artenkennzeichen nur bestatigeu.

der Mittellinie des Kopfes bis auf den Nackenlappen fort, wodureh es den Anscheiu gewinnt als seien die Nacken- lappen durch einen Federstreif getrennt (wie bei G.javanensis). Eine genauere Untersuchung überzeugt aber bald, dass die Nackenlappen an der Basis stets verwachsen sind, wie dies auch die Figur im Hintergruude (auf Tav. IX bei Salvadori) zeigt. Die seitliche Basis der in einen schmalen Hautstreif auslaufeuden Nackenlappen zieht sich nicht wie bei G. javanensis bis zur Höhe des hinteren Augenrandes , sondern nur bis oberhalb der Ohrgegend. Bei unseren Exemplaren lauft die seitliche Basis der Nackenlappen übrigens nicht nahezu mit dem nackten Flecke unter den Augen zusammen, wie dies Salvadori's Abbildung zeigt, sondern ist durch einen Federstreif getrennt (s. Fig. 9), was rait von der Praparation der Balge herrühren mag.

Der weisse Spiegel der Handschwingen zieht sich (mit Ausnahme der ersten rudimeutaren) über sammtliche zehn, und ist auf der T^en oder S^en am breitesten (54 64 mm.) ; auf der zweiten Schwinge ist das Weiss meist nur auf die Inneufahue beschrankt, zieht sich bei zwei Exemplaren aber auch auf die Ausseufahue. Die Armschwingen zeigen (mit Ausnahme der zwei oder drei letzten) auf der Mitte einen mehr oder minder ausgedehuten , meist schmalen , langlichen weissen iSchaftfleck , wie dies die verkleinerte Figur eines Exemplares mit ausgebreiteten Flügeln auf Salvadori's Tafel gut darstellt. Nur bei einem alten Mann- eken (M.S. Cat. N". 1) sind die weissen Schaftflecke auf die drei ersten Schwingen zweiter Ordnung beschrankt.

Die Farbung stimmt genau mit der von G. javanensis überein und zeigt denselben lebhaft purpurvioletten Schein auf Mantel und Schultern (der auf Tav. IX von Salvadori unrichtig in Grün wiedergegeben ist). Zu erwahnen ware noch , dass vier unserer alten Vogel auf den Federn der Bauchmitte sehr schmale graulich verwaschene Endsaume zeigen .

Die Nackenlappen stimmen in Form und Grosse ganz mit denen von G. robusta überein , sind wie bei dieser Art mehr breit als lang und an der Basis mit einander verwachsen, übrigens bei beiden Geschlech tern ganz gleicb. Ein altes Mannchen (Fig. 14) besitzt die kleinsten Nacken- lappen , ein anderes Mannchen hat dieselben fast so gross als das alte Weibchen (Fig. 13). Der seitliche Basisstreif der Nackenlappen ist bei einem Exemplare langer als dies Fig. 12 zeigt und zieht sieh fast bis zum oberen x\ugen- rande , also fast ganz wie bei G. javanensis.

Aber selbst das kleinste Exemplar von G. batuensis, mit dem schmalsten Spiegelfleck , welches sieh dadurch gewissen Exemplaren von G. javanensis ausser- ordentlich nahert, unterscbeidet sieh noch immer leicht durch die Form der Nackenlappen.

Der weisse Flügelspiegel ist wie bei G. javanensis (2te 8*^ Schwinge, auf der sechsten 20 ram. breit). Die Vertheilung der Nackttheile weicht, nach dem einen Exemplare unseres Museums zu urtheilen (altes 9, Coll. Dr. Platen 1877), insofern von G. javanensis ab, als der seitliche Basishaut- streif der Nackenlappen sich bis zura hinteren Augenrande hinzieht. Die Nackenlappen selbst sind massig gross (ca. 12 mm. lang und ebenso breit), im übrigen ganz wie bei G. javanensis, an der Basis durch einen sehr schmalen Hautstreif verbunden , wie dies bei gewissen Exemplaren von javanensis auch der Fall ist (vergl. Fig. 5).

Die Art fehlt unserem Museum , ich untersuchte aber Exemplare von den Nicobaren (Wiener Museum) und An- damauen (Port Blair : Museum Turati) und verglich die- selben mit Exemplaren von Gr. intermedia von Burma und Gr. javanensis von Java. Nach meinen Aufzeichnungen unterscheidet sich Gr. andamanensis schon dadurch , dass der nackte Fleck unter dem Auge durch einen Federstreif von der nackten Basis der Nackenlappen getrennt ist (vergl. Fig. 16 und 15), und stimmt daher in diesem Character zunachst mit Gr. javanensis überein. Die Nackenlappen (15 17 mm. lang) sind so gross als bei letzterer Art, scheinen also grosser als bei Gr. intermedia ,vi\eA.\e Y)im.eu- sionen im AUgemeinen; dagegen ist die Farbung, wie die Ausdehnung des weissen Flügelspiegels (auf der 2ten bis 7ten Schwinge ^)) ganz so wie bei Gr. intermedia.

UEBER DIE ARTEN DER GATTUNG THERISTICUS WAGL,

Dr. O. PINSCH.

Dr. Sharpe unterscheidet im Cataloge des British Mu- seum (Vol. XX.VI, 1898, p. 21—23) nur zwei hierher ge- hörige Arten {Th. melanopis und Th. caudatus)^ indem er Th. Branickii Berlepseh als jungen Vogel mit ersterer Art vereinigt. Nach sorgfaltiger Vergleichung des Materials in uuserem Museum kann ich mich diesem Vorgange nicht anschliessen, sondern halte Th. Branickii fur eine ausge- zeichnete Art, der ich noch eine neue Art hiuzuzufiigen habe :

Theristicus columhianus,, sp. n. Ihis rnelanopis Schl. in Mus, Lugd.

Diagnose : wie Th. caudatus vom Kropfe an einfarbig schieferschwarz, aber die Schwingendecken und die ver- deckte Basis der Armsch wingen nicht weiss wie bei cawc^afus, sondern grau (wie bei melanopis).

Rücken, Schultern und die kleinen oberen Flügeldecken am Uuterarm sind braun, mit grünem Metallschein und kaum bemerkbaren helleren Endsaumen, die nur auf den kleinen oberen Flügeldecken deutlicher hervortreten. Kopf und Hals sind schmutzig rostgelblich, die etwas schopfartig

verlangerten Federn des Hinterkopfes duukler, rostbraun- lich. Kinn und Kehle sind befiedert und nur jederseits an der Basis des Unterschnabels zieht sicli ein (ca. 20 mm. langer) nackter Streif lierab.

Das Exemplar ist unzweifelhaft ein altausgefarbter Vogel den das Reichs- Museum 1867 voo DeyroUe in Paris kaufte, mit der Angabe »Columbie", leider ohne Augabe des nahe- ren Fuudortes und Sammlers.

Wie es scheiut ist bisher noch keine Art dieser Ibis- Gattung in diesem Theile Süd-Americas nachgewiesen.

Das Reichs-Museum besitzt davon zwei Exemplare, wo- von das eine (M.S. Cat. N». 1 = Schl. N». 4) noch aus dem alten Cabinet Temminck herstammt und hier als » Tan- talus albicollis Lath." bezeichnet war (Temminck : »Catal. syst. 1807, p. 168 N». 770), angeblich von »Cayenne". Das Exemplar ist keiueswegs »au plumage imparfait" (Schlegel) soudern altausgefarbt und zeichnet sich vor allem durch das tiefe Rostbraun auf Kropfmitte, Ober- u. Hinterkopf aus , der übrige Hals ist dunkel rostgelb. Die Oberseite ist dunkel graubraun mit wenig hervortretenden helleren Federenden. Kinn und Kehle sind nackt, mit einem schmalen Federstreif langs der Mitte, der aber nicht durchgeht.

Das andere Exemplar (M.S. Cat. N^. 2 = Schl. N«. 3) ist ein altes Weibchen und wurde am 21 Januar 1826 bei Cai9ara im Innern der Provinz Matto Grosso von Joh. Natterer ■•) gesammelt. Es stimmt gauz mit dem alten Vogel (N". 1) überein, ist aber im Ganzen heller gefarbt, das Rostbraun auf dem Oberkopfe ist blasser und fehlt auf dem

Sie uuterscheiden sich auf den ersten Blick durch den ansehnlich kiirzeren und schwacheren Schnabel, sowie die helle Fiirbung von Kopf, Hals und Brust. Nur der Ober- und Hinterkopf, sowie die unteren Halsseiten und die Kropf- mitte sind rostgelblich , der übrige Hals und die Brust sind fast rein weiss und dieses Weiss bedeckt auch die ganze Bauchmitte und zieht sich bis auf den After. Der graue Ton der Oberseite stimmt ganz mit Th. melanopis überein , aber die Schwingendecken sind nicht lichtgrau, sondern duukelgrau und kaum heller als der Oberflügel.

On a Benhamia-species from Paramaribo.

Among a lot of worms, collected in Paramaribo^), I met with a dozen of small ^éw/jama-specimens, which cannot

be identified with one of the species of this genus, descri- bed from America. The number of these species however is not very large. Rosa described a couple

of them from Mexico ^) and Pa- ragay '), and Eisen in a recent paper 1. 2. 3. on Pacific Coast

four new species from Mexico and California. In this

1) See Notes from the Leyden Museum, Vol. XX, 1898, p. 202. The specimens of Pontoscolex corethrwrus, mentioned in this paper, probably belong to Eisen's variety mexicanus (Festskrift for Liljeborg, 1896, p. 8), for they differ from the East-India specimens by having not 130 or more segments from head to caudal zone, but only 103 to 120.

plentifully illustrated memoir he not only published detailed descriptions and figures of his new species , but also of several other allied forms, making thus comparison of the different American species very easy. Though Eisen's dis- covery of Benhamia-species at Miraflores »in a locality to which plants of any kind have rarely if ever been intro- duced directly from foreign country" would indicate that they must be considered as truly endemic, I nevertheless thought it desirable to compare our worms also with the African species, 1°. because there exists a close connection between the fauna's of West- Africa and West-India, 2°. because , Paramaribo being a sea-port , our species could have been imported by man's interference, like in many other parts of the world. Thanks the investigations of Michaelsen we know about twenty species of Benhamia from Africa, whose body-length does not exceed 75 mm. ; on comparing them with our worms, B. pallida^) from Togo, appears to be the only species, that shows some resem- blance with them , especially in the feature of the penial setae. Unfortunately the description of this species is rather incomplete , being based on a single indifferently preserved individual.

Our specimens attain a length of no more than 50 mm. ; the breadth of the body in the clitellar region is about 3 mm. The number of segments of a large specimen is 133. The colour of the body is greenish , only the cli- tellum and setal areae are whitish. The intersegmental groove between the first and second segment is rather indistinct. The cephalic lobe extends with a roundish prolongation till the half of the buccal segment. The segments behind the clitellum show a circular ridge in the middle, upon which the setae are situated ; the distance between de ventral pairs of setae is a little larger than that between the ventral and dorsal ones. Clitellum saddle- shaped, occupying segments XIII XX, the anterior and

the posterior of them only partly glandular; the prostate- pores upon segments XVII and XIX, on an elevated, elliptical area, connected by a groove, that on segment XVIII is faintly curved towards the median line. The oviducal pores separate, hardly visible, at the mesial side of the ventral setae, a little more anteriorly. First dorsal pore in the intersegmental groove III/IV. The sperma- thecal pores in the groove between segments VII and VIII , VIII and IX , in the series of the ventral setae , connected by a glandular ridge.

The penial sac contains two setae of different shape, but of about the same length (0.6 mm.). The larger of them is 0.014 mm. thick, slightly curved over the fourth distal part of its length and furnished with several distant tubercles; the other seta is much more slender, quite plain , ending abruptly in a fine apex like in B. culminis Mich. Each prostata consists of a rather large, linguiform gland, with a knee-shaped bend in the middle, and opening unto the exterior by a curved , much thinner, muscular duct. Each spermatheca is a pyriform pouch separated by a constricted part from the wide, globular duct, which is about equal in size ; the latter bears in its middle a small spherical diverticulum, furnished with a short duct. In diffe- rent individuals however the shape of the spermathecae is somewhat variable, sometimes it is more elongated, resem- bling those of B. palmicola'). The 11th, 12th and 13th septa are specially thickened. The buccal cavity is usually everted ; the two gizzards lie in segment IX. There are three pairs of calciferous glands in segments XV XVII; only the two anterior ones contain lime crystals.

In the segments behind the clitellum the nephridia are arranged in five rows on either side of the median line, the first of them between the ventral and dorsal rows of setae.

As already stated above, our specimens most resemble

30 DESCRIPTIONS OF EAHTII WORMS.

B. pallida, especially with regard to the appearance of the peuial setae; however these setae seem not to be quite similar, for, according to Michaelsen's description and figures, they are of larger size, more curved and only furnished with tubercles at their concave side. Also his description of the prostata-glands »sehr fein, schlank, schlauchformig" does not exactly correspond to our species. As Michaelsen however only had a single specimen at his disposal, and his description therefore remained somewhat incomplete, it is difficult to decide whether our specimens belong to the same species.

LEPTOPOMA MANADENSE VAR. 34

NOTE IV.

ON A NE¥ VARIETY OF LEPTOPOMA MANADENSE PER.

M. M. SCHEPMAN.

The specimens of a lot of a Leptopoma, collected by Baron von Rosenberg at Gorontalo, Celebes, have the general ap- pearance of some varieties of L. vitreum Lesson, but their columellar margin is simple, I had compared them with the species of the genus known from Celebes, but I could not identify them with any of these. So I sent a few specimens to Prof. E. von Martens and asked his advice, and this author declared them to be a variety of L. mana- dense Pfr. (As I had compared them with typical speci- mens of this species agreeing with the figure in Pfeiffer's Novitates conchologicae, Vol. IV, pi. 128, fig. 9, I did not come to this identification). The specimens indeed agree rather well with the figure of von Martens' Ostasiat. Landschn. (PI. 2, fig. 8), but as this figure differs much from the typical one and from the original description, I thought it might be somewhat erroneous; now this figure may serve for the new variety, which I describe under the name of:

Leptopoma manadense Pfr. var. ohsoleta.

The shell differs from typical ones by the peripherical keel, which in most of the specimens is only indicated at

Isfotes from tlie Leyden Museuin, Vol. XXI.

the beginning of the last whorl and disappears towards the aperture, being only faintly visible on the whole whorl in very few specimens , the supra-peripherical keels are entirely wanting; right margin of aperture without the angle resulting from the keel in typical specimens.

The shells vary much in coloration, they are white, with or without a brown band at or slightly below the periphery, the upper part is spotted or flamed with brown, the spots and flames varying in size, a few specimens have a brownish yellow ground-colour; the lower part of the last whorl is lighter. Shape and size agree with typical specimens.

Herr R. Oberthür hatte die Güte , mir eine Reihe neuer Paussiden seiner Samraluüg zur Beschreibung zu übersen- deii. Einige andere Arten wurden von Herrn C. Ritsema aus dem Rijksmuseum von Leiden eingesandt. Hiezu kommt noch eine von Dr. Hans Brauns und eine von Herrn Rob. Ch. Wroughton aufgefundene Art. Ich statte den Herreu Einsendern hiermit meinen Dank ab. Leider liegt nur für eine eiuzige der hier erwabnten Paussiden die Angabe der Wirthsart vor.

Nach der Beschreibung der Arten werde ich einen Nach- trag beifügen zu der in Baud XVIII der » Notes" ^) S. 75 und 76 gegebeneu Liste der Paussiden- Wirthe.

Thorax transversus , sub- tiliter marginatus , basin versus modice angustatus , vix cordiformis, longitudinaliter canaliculatus, prope angulos posticos foveolatus. Elytra utrimque foveola basali instructa, lateribus subrotundatis. Tibiae basi angustae , apicem ver- sus sensim dilatatae, compressae; auticae siuuatae et apice emarginatae. Tarsi breves , art. 1*^ et 2^ angustis , perbre- vibus , 3"^ et 4^ late bilobatis , 5^ ceteris unitis lougitudine aequali. Loug. 5,5 mm.

Von H. hrasiliensis Westw. besonders durch die schma- leren Pühler, deren Glied 1 und 2 ganz anders gebildet ist, verschiedeu. Ueberdies durch geringere Grosse, dunklere Farbung, stark glanzende, glatte Oberflache , brei teres Hals- schild , seitlich gerundete Flügeldecken und die namentlich an der Basis schmaleren Schienen von jener Art abweichend.

Ein Exemplar aus der Sammlung von Herrn R. Oberthür lag mir vor mit der Etikette: » Ecuador, Semiradski, 1882—83."

Die Verwandtschaft mit den Oarabiden tritt bei Homo- pterus , besonders bei obiger Art , starker hervor als bei den übrigen Paussiden ; sie aussert sich namentlich in der Er- weiterung der Tarsen , die , wie die Form des Halsschildes und des gesammteu Rumpfes , an Lebia erinnert.

Von Cerapterus myrmido7ium Kolbe (Ent. Nachr. 1896, n''. 19) lag aus R. Oberthür's Sammlung ein Exemplar vor mit der Etikette: »Semnio , Njam-Njam (Bohndorff!)", wel- ches aus derselben Quelle stammt wie Kolbe's Original- exemplar und auch in allen Einzelheiten der Beschreibung, selbst in der Grosse, mit letzterem übereinstimmt.

NEUE PAUSSIDEN. 35

Für neu halte ich dagegen die folgendeu von R. Ober- thür zur Ansicht vorliegenden Arten :

Cerapterus longipennis , n. sp.

Gracilis , nigropiceus, antennis pedibusque rufopiceis, sub- nitidus , densius fulvohirsutus ; elytrorum macula hamata apicali ferruginea intus abbreviata instructa. Antennae ca- pite thoraceque multo longiores, latitudine fere quintuple longiores. Thorax longitudine plus duplo latior, margine antico et postico subtiliter punctato. Elytra latitudine duplo et dimidio longiora, subtilissime alutacea (propterea parum nitida), seriebus punctorum subtilium regularium extra re- gionem suturalem instructa ; limbo apicali recur vo utrim- que remote 4-dentato. Long. 14 mm.

Mit Cerapterus hottentottus Kolbe (Ent. Nachr. 1896, n°. 19) nahe verwandt, von derselben , auffallend schlau- ken Gestalt, auch mit ahnlicher Fühlerbildung und Punk- tirung der Flügeldecken. Er unterscheidet sich jedoch von ihm durch den ganz verschiedenen Apicalsaum der Flügel- decken , der nicht wie bei C. hottentottus , Smithi und con- color fein und dicht gezahnelt ist, sondern jederseits nur vier grosse, vs^eit von einander abstehende Zahne aufweist. Ferner ist C. longipennis viel dichter fuchsig behaart als hottentottus, das Halsschild ist breiter , am Vorder- und Hinterrande fein aber deutlich punktirt, die Punktreihen der Flügeldecken beginnen bereits nahe der Naht (sind also zahlreicher als bei hottentottus) und die Körpergrösse ist eine viel geringere. Er stammt vom Tauganika-See, wahrend hottentottus am Ngami-See in Südafrika gefunden wurde.

1 Exemplar mit der Etikette: » Region de M. Pala,Tan- ganika, (R. P. Guillemé!)".

Nur mit Bedenken beschreibe ich die folgende Cerapte- 7'Ms-Art als neu, da mir kein Exemplar von C. Lafertei Westw. zum Vergleiche vorliegt und ich nur nach der Beschrei- bung und Abbildung im Thes. Ent. Oxon. urtheileu kann.

36 NEUE PAUSSTDEN.

Cerapterus Denoiti , n. sp.

Nigropiceus , nitidus, antenais pedibusque piceis , ely- trorum macula ferrugiuea hamata a medio usque ad apicem pertingente. Antennae breves, latissiraae, elytrorum basin tantum attingentes, absque articulo basali latitudine duplo tantum longiora. Thorax longitudine plus duplo latior, impunctatus, linea longitudinali media impressa. Elytra brevia, densius subtiliter punctata, margine apicali simplici. Tibiae latissimae, etiam posticae latitudine vix dimidio lon- giores. Long. 11,5 mm.

Mit C. Lafertei Westw. nahe verwandt, aber mit noch kürzeren , breiteren Pühlern und kürzeren , breiteren Schie- nen. Die Fühler erreichen nur den Hinterrand des Hals- schildes, ihre Keule (Glied 2 10) ist nur doppelt so lang als breit, die Glieder 3 9 fast linienförmig wegen ihrer Kürze und grossen Breite, Glied 10 fast so lang wie die 4 vorhergehendeu zusammen.

Die Schienen sind ebenfalls sehr breit und kurz, kaum um die Halfte langer als breit. Die Farbung und Punk- tirung der Flügeldecken entspricht dem C. Lafertei', sie sind fein und ziemlich dicht puuktirt und haben einen be- reits in der Mitte beginnenden rothgelben Hakenfleck , dessen beide Aeste (ara Rande und an der Naht) gleich lang sind und eiuander parallel laufeu.

Das Halsschild ist sehr breit , schwarzbraun , mit deut- licher Mittelliuie.

Von Gerapt, trinitatis Kolbe (Ent. Nachr. 1896, n». 19), der ebenfalls sehr breite Fühler und Schienen besitzt, be- sonders durch den eiufachen Spitzensaum der Flügeldecken und den langen rothgelben Hakenfleck derselben ver- schieden.

I Exemplar mit der Etikette : » Uganda, R. P. Denoit!" aus R. Oberthür's Sammlung lag vor. Ich beueune die Art zu Ehren des Entdeckers.

Long. 6,5 mm.

Da ich ein von Raiïray übersandtes Exemplar des P, lineatus Thunbg. aus Capstadt besitze, welches ich für ty- pisch halte , sehe ich mich genöthigt, die oben beschriebene Form als neue Art aufzustellen , da sie in der Sculptur sowie in der Form der Fühlerkeule von ersterem bedeutend abweicht. Die Unterschiede sind folgende:

P. lineatus Thunbg.: Matt, fast glanzlos, die Flügel- deckeu séhr dicht ruuzlig puuktirt, ohne Puuktreihen. Die Langsrinne des Clypeus kurz und undeutlich. Die Fühler-

P. semilineatus Wasm. : Thorax stark glanzend , Flügel- decken etwas minder stark, nur der Kopf matt. Flügel- decken sehr fein chagrinirt , mit deutlichen Punktreihen. Die Langsrinne des Clypeus lang und deutlich vertieft. Die Fühlerkeule an der Spitze gerundet , glanzend , sehr fein chagrinirt und sparlich punktirt, die 5 Eindrücke des oberen Randes seicht, besonders der letzte (vor der Spitze befindliche).

1 Exemplar lag vor , von Herrn Dr. Hans Brauns bei Port Elizabeth (Capkolonie) im Nest von Acantholepis ca- pensis Mayr entdeckt.

Von P. Afzelii Westvr. {laetus Gerst.) unterscheidet sich semilineatus besonders durch den Mangel der Tuberkelu am oberen Fühlerrande und die viel schwacheren Eindrücke.

Eiue Art, deren Verwandtschaft ziemlich schwer festzu- stellen war. Unter den Arten mit tief zweitheiligem Tho- rax ausgezeichnet durch die relativ sehr kleine, blasenför- mige, beiderseits scharf gerandete Fühlerkeule , deren Basis oben einen massig langen , stumpfen , dreieckigen Zabn hat.

Von P. cilipes uud armatus Westw., die eine ahnliche Fühlerbildung haben, durch den Mangel des Stirnbornes verschieden ; von P. laevifrons , ajinis und cognatus Westw., durch den tief zweitheiligen Prothorax verschieden.

lm übrigen in der Gestalt ahnlich dem ostindischen P. cognatus, der eine ahnliche, relativ ebenso kleine Fühler- keule und ahnliche, aber starkere Stirueindrücke besitzt.

Ein Exemplar (9) aus dem Rijksmuseum von Leiden lag vor, mit der Etikette: »Stampfli, Junkriver, Liberia".

Paussus Humholdti Westw. und Var. laevicornis m.

Von P. Humholdti Westw. lagen mir aus dem Leideuer Rijksmuseum 2 Exeraplare vor aus Liberia (Starapfli, Junk- river). Das kleinere misst 9 mm., das grössere 12 mm. Beide stimmen mit Humholdti Westw. im wesentlichen überein und wurden auch von C. A. Dohrn als diese Art bestimmt. Bei dem grosseren der beiden Stücke ist jedoch der Thorax von der Breite des Kopfes, bei dem kleineren ist es sogar eher etwas schmiiler als den Kopf [bei West- wood heisst es (Thes. Ent. Oxou. p. 83) »prothorace capite evidenter latiore"]. Bei dem kleineren sind die 4 Querfur- chen auf der Fühlerkeule deutlich, wenngleich sehr schwach; bei dem grosseren ist die Keule ganz glatt und selbst bei starker Vergrösseruug sind keine Querfurchen zu erkennen (Var. laevicornis Wasm.).

Von Paussus WaterJiousei Westw. (Thes. Ent. Oxon. p. 90, PI. XVI, Fig. 4) lagen mehrere Exemplare vor, die

ich trotz der beim Vergleich rait Westwoods Beschreibung und Abbilduug sich ergebenden kleiueu Differenzen nicht von jener Art zu trennen wage. Die Seitenecken des vor- dern Prothoraxtheiles siad uicht so spitz vortretend und die Breite desselben daher kaum oder nicht bedeutender als die Kopfbreite. Der vScheiteleindruck bildet nicht eine tiefe ringsum gerandete Grube , sondern zwei hohe , fast ohnnuschelförmige Hoeker , deren Höhlungen einander zu- gewaudt und durch eine breite Langsfurche getrennt sind.

Die Fundorte der 4 mir vorliegenden Exemplare sind :

Taudjong Morawa, Serdang (N. O. Sumatra), Dr. B. Hagen ! 1 Ex. aus dera Rijksmuseum (5 mm. lang).

Malacca, Perak , W. Doherty! 2 Ex. aus R. Ober- thür's Sammlung (6 mm. lang).

Haute Birmanie, État de Momeit, 660 M., W. Doherty! 1890. 1 Ex. aus R. Oberthür's Sammlung (6 mm. lang).

Das Exemplar aus dem Rijksmuseum wurde auch von C. Ritsema als Waterhousei bestimmt.

Von Paussus Klugi Westw. lagen aus R. Oberthür's Sammlung 3 Exemplare vor vom Kilima Ndjaro (Ostafrika), von R. F. Le Roy 1890 gesammelt. Dieselben unterscheiden sich von den südafrikanischen Stücken nur durch ein we- nig starkeren Querwulst des Hinterkopfes und ein wenig stjirkere Punktirung der Flügeldecken.

Eiue scblanke Art , vou der Gestalt und Grosse des P. Klugi Westw. , auch durcb die Fühlerbildung zur Klugi- Gruppe gebörig. Der lange , breit langsgefurchte Kopf ge- hort jedoch eiuem ganz anderen Typus an und erinnert an P. Shuckardi und Curtisi, so wie an Germari und Schaumi. Die Fühlerkeule (Fig. 5) von LeRoyi ist so lang wie der Kopf und der vordere Theil des Prothorax zusam- men , sehr schwach aber doch deutlich gekrümmt, von ahn- licher Form wie bei P. Klugi, aber breiter und seitlich stiirker zusammengedrückt, nicht parallel, sondern von der Basis bis zur sehr stumpf gerundeten , fast abgestutzten , Spitze geradlinig verengt; der Vorderseite zeigt eine durch- gehende breite Langsfurche, der Hinterrand ist schmal und tief von der Basis bis zur Spitze gefurcht, mit 6 Gruben innerhalb der Furche , aber mit völlig geraden , ungezahn- ten Randern der Furche. Die verbreiterten Schienen , be- sonders die Hinterschienen, unterscheiden diese Art ebenfalls von allen Verwandten.

Geliört mit P. Kannegieteri Wasm. (Notes Leyd. Mus. XVIII, p. 67 u. Taf. 1, Fig. 2) zu jener Abtheilung der javanischen Paussiis, die eineu Uebergang zwischen deu A.rten mit eiförmiger (nicht ausgehöhlter) und mit muscbel- förmiger (tief ausgehöhlter) Fühlerkeule bilden; die eiför- mige, stark blasenförmig verdickte Keule ist namlich an ihrem Hinterrande nicht ausgehöhlt sondern nur flach ge- furcht, die Furche am Hinterrande gezahut; an der Basis der Keule befinden sich 3 Zahne. Javanus unterscheidet sich von Kannegieteri durch die braune Farbung, die dich- tere Punktirung und Behaarung, den kürzeren Prothorax und namentlich durch die viel kürzere und dickere Fühlerkeule (vgl. die Fig. 10 u. 11), an welcher der Rand der Rücken- furche nur ganz stumpf gezahnt ist ; von den 3 Zalmen der Basis ist der hintere noch langer und spitzer als bei Kannegieteri , der mittlere viel undeutlicher und stumpfer ; zwischen dem mittleren und dem vorderen Zahn findet sich ein tiefer Ausschnitt.

Mit P. Humhloti Raffr. und opacus Kr. verwandt, be- sonders mit letzterera. Von ersterem durch die matte Sculp- tur, die eiuförmig braunrothe Farbung und der Bildung der Fühlerkeule verscbieden, deren Vorderrand keine Grübchen besitzt sondern nur furchenartig eingedrückt ist. Mit P. opacus Kr. in der matten Sculptur und in der Form der Fübler sehr abnlich, aber scblauker, mit glanzenderem , langerem Kopfe, starker erweitertem und verlangertem Kopfschild und grösserer Füblerkeule, die nocb starker ausgeböhlt ist. Die Vorderecken des breiten Kopfschildes sind nicht niedergedrückt , sondern schwacb aufgebogen. Die Scbeitel bat drei tiefe scharf begrenzte Eindrücke, von denen der mittlere furchenförmig , die seitlichen gru- benförmig sind. Der vordere Theil des Prothorax ist ganz anders als bei opacus, indera die öcbeibe zu beiden Seiteu des Mitteleiudruckes starker gewulstet ist und die Seiten vor den spitzen dornförmigen Seitenecken tie f ausge- bucbtet sind, wahrend sie bei P. opacus geradlinig bis zu den stumpfen Seitenecken verlaufen (vgl. Fig. 12 a u. 13). Feruer ist der Prothorax bei opacus nur so lang als breit, bei Oberthüri tast um ein Drittel langer als breit.

Von P. Sikoranus Dohrn unterscheidet ihn der Mangel der Tuberkeln auf den Flügeldecken , die verschiedene Sculptur und Grosse. Von P. Sikorai Pouj. {Grandidieri Pouj.) namentlich die kahnförmige, nicht beilförmige Füh- lerkeule (vgl. Fig. 7 u. 12).

In der Furche zwischen Vorder- und flintertheil des Halsschildes steht jederseits ein kleiner gelber Haarbüschel und die Spitze der Flügeldecken ist wie bei opacus mit einer Reihe kürzerer dornförmiger Haarpinsel besetzt , vor denen einfache Börstchen stehen.

Mit P. opacus Kr. ebenfalls nahe verwandt, von ibm jedoch durch den tief eingedrückten , jederseits beulenartig aufgetriebenen Oberkopf verschieden ; jede der zwei Beulen bildet ein kurzes, offeues Scbeitelborn. Aucb ist die Fübler- keule viel langer uud sebmaler als bei P. opacus, gegen die Spitze ganz allmablicb stark verengt (daber von vorne geseben fast spitz-dreieckig) ; sie ist mebr als doppelt so lang als an der Basis breit und der Hinterrand ibrer Aus- böblung tritt nicht so hoch vor wie bei P. opacus. Von dem gleichfalls nahe verwandten P. Oberthüri W asm. duvch. das seitlich nicht ausgeschnittene Halsschild und durch den viel kürzeren , glanzlosen , viel tiefer und breiter einge- drückten Kopf verschieden. Das Kopfschild ist viel kürzer und sebmaler als bei jenen beiden Arten , in der Mitte nur ausgerandet und an den Seiten nicht aufgebogen oder vorgezogen ; es ist fein scbwarz gerandet (vgl. die Fig. 12, 13a, 14).

PaRT II. Brachyura. ') (Plates 5—12).

Like the Macroura, also the Brachyura collected by Dr. Biittikofer in Central Borneo ought to be considered as a valuable contribution to the Carcinological Fauna of this Island. Fifteen species were collected, all but one fresh- water forms, inhabitants of the Kapoeas-basin and of the Upper Mahakkam, and of these 14 Land- and Freshwater- species no less than eleven or twelve proved to be new to Science! As far as I am aware, only three freshwater crabs were hitherto known to inhabit the large Island of Borneo, viz. Parathelphusa tridentata H. M. E., Potamon borneense v. Mart, and Pot. loxophthalmum de M. Now, however, this number has increased quintuple ! Firstly a remarkable new species of Menippe ought to be mentioned.

that was captured at Sanggau on the Middle Kapoeas. It is closely allied to the rare Menippe Panope Herbst from Tranquebar, a species not yet found back since Herbst, as far as I know, and that perhaps once may prove to be also a freshwater crab, whereas the other representa- tives of Menippe and Myomenippe are marine forms. A new description and a figure of the equally little-known Myomenippe Fornasinii, made after a type-specimen from the Paris Natural History Museum, is added, though this species was not collected. A pretty small Sesarma proved also to be new, unfortunately the locality was not defined, but very likely it has been collected at Sintang.

The other 11 or 12 species are all Thelphusidae. Pa- rathelplmsa tridentata H. M. E. is represented by 15 spe- cimens; this species is, already since 1868, known to in- habit Borneo by von Martens. This author described in the same year also a new Potamon from Borneo, Potamon borneense, a new variety of which was now collected, pro- bably at Sintang. For this species and for two other new ones a new subgenus Perithelphusa is established.

An interesting new species, belonging to the subgenus Potamon s. s., was discovered by Dr. Nieuwenhuis on the Upper Mahakkam , and another allied form on Mount Damoes and on the Upper Sibau river. Both were compa- red with type-specimens of Pot. sinuatifrons H. M. E. from the Paris Museum.

On the Liang-Koeboeng Chain a remarkable new Po- tamon was captured, that bears a striking resemblance to Pot. austenianuni W.-Mas., a species that inhabits Assam and that evidently is represented in Borneo by the new species. The four remaining belong to the subgenus Geot/iel- phusa and are all new to science.

Professor Burger of Göttingen was so kind as to send me the type-specimens of the Thelphusidae described by him in 1894. None of these species from the Philippines and Cape York proved to be iden- tical with those of the Borne o-E xpeditiou and I

could state, moreover, that Potamon smwa^i/ro^rs H. M. E., the habitat of which was still unknown, is indeed an in- habitant of the Philippine Islands.

As regards the localities where the species were col- lected, I refer the reader to Dr. Büttikofer's account of the Expedition, published in Vol. XIX, 1897, pp. 1 25.

» Ortmunni, n. sp. Middle Kapoeas.

Notes from the Leyden Aluseum, Vol. XX.I.

56 CFIUSTACEANS OF THE

Myomenippe Hilgd.

Myomenippe apparently contains only two species : Myomenippe Hardivickii Gray. » Fornasinii Bianc.

Menippe Bumphii Pabr. is identical with Menippe Belan- geri H. M. E., but Menippe Bumphii H. M. E. is au American species, inhabiting the coast of Brazil (A. Milue Edwards, Etudes sur les Xiphosures et les Crustacés de la Region Mexicaine, p. 263, PI. 48, fig. 4).

Me7iippe granulosa Strahl (1861) is, according to von Martens (1872), identical with Menippe Panope Herbst.

There can be no doubt that Myomenippe Hardioickii Gray, the type of which is from the Indian Ocean, and Myom. duplicidens Hilgd. from South Celebes are one and the same species (confer: Miers, Annals and Magazine Nat. History, Ser. 5, Vol. 5, 1880, p. 233). As I have previously shown (in : The Journal of the Linueau Society, Vol. XXII, 1888, p. 40), Myom. duplicidens Hilgd. is also identical with Myom. granulosa A. M. E. (1867).

The second species of Myomenippe., found in the Indo- pacific Seas, is Myom. Fornasinii Bianc, described below.

Pelaeus armatus Eyd. & Soul. (Voyage de la Bonite) belongs, according to Dana, to the genus Menippe and I am of the same opinion. This species, that occurs at the Sandwich Islands, differs by several striking characters from the four other species of this genus. The front is quadridentate, the first and the second an tero -lateral tooth are lobate and incised, the third is acuminate anteriorly, the fourth is spiniform.

Menippe guadridens de Haan and 31en. af finis de Haan, both from the Moluccas, are nomina uuda (Fauna Japo- nica, p. 21).

Menippe Martensii Krauss from Natal and the Red Sea is apparently uo Menippe, because the fingers are exca- vated and because the cephalothorax and the front have a different shape.

Herklots (Symbolae cai-cinologicae, 1861 , p. 11) makes still mention of a Menippe tetrodon de Haan from the Moluccas, but this species is not recorded in the » Fauna Japonica."

Menippe signata White from the Mauritius and Meiiippe? Cuniingii White from the Philippine Islands are nomina nuda; the latter is apparently no Menippel (Gray, List of the Crustacea of the British Museum, 1847, p. 19).

Two type-specimens of Menippe Leguillouii A. M.

from the Coast of Mozambique that in 1878 were described by the former under the name of Menippe Fornasinii^ and Dr. Romer thereupon informed me that it was iden- tical with them. I therefore conclude that Bianconi's species and Myomenippe Leguillouii A. M. E. are indeed one and the same species.

Galene'^ Jiirtipes Jacq. and Lucas and Myom. Leguillouii A. M. E. are apparently ideutical, as both the description and the figures in the » Voyage au Pole Sud" fully agree with the type specimens of the latter.

Ortmann refers to this species also Haswell's Para- ruppellia saxicola from the Eastern coast of Australia, which indeed appears quite probable. As also a specimen of Myom. granulosa A. M. E. from the Mergui-collection is lying before me, it will be easy to indicate the prin- cipal differences between the two species of Myomenippe.

As regards their outer appearance, the general shape of cephalothorax and legs, both species closely resemble one another. The front and the orbits show the same characters, fully agreeing in the number and the form of the teeth. Behind the outer angles of the orbits that are acute and dentiform , in both specimens four teeth are observed and in both the second is the largest of all. This second tooth, however, appears in M. Fornasinii slightly longer in proportion to the first than in Myom. granulosa A. M. E. In M. granulosa A. M. E. the distances between the tip of the second tooth and those of the third and first are about in proportion as 3:2, but in Bianconi's species as 5:3. The first and the second tooth are moreover less prominent in M. Fornasinii., the second tooth indeed is 8-times as long as high, but in Myom. granulosa 6 times: in other words the anterior margin of these teeth appears somewhat shorter in proportion to their length than in Myom. granulosa A. M. E. The margins of the autero-lateral teeth are finely granulate in M. Fornasinii, but in the other the granules are conical, more prominent and less numerous. The inter-

regional grooves are, at least on the anterior half of the upper surface, quite distinct and moderately deep in M. granulosa, but they are almost wanting in M. Fornasinii', the mesogastric furrow that bifurcates posteriorly, reaching, however, only till the middle of the gastric region , is faintly indicated and so also the lateral portions of the cervical suture, the grooves between the gastric region and the anterior branchial one , but other grooves are not to be seen. In M. granulosa the regions of the upper surface before the line that unites the antero-lateral teeth of the last pair with one another, are distinct and well- defined, more or less prominent and covered with coarse granules, but the interregional grooves and furrows are smooth ; in M. Fornasinii on the contrary the regions are scarcely distinct, inconspicuous, and the whole upper surface of the cephalothorax appears smooth to the naked eye. Only when the carapace is examined under a strong magnifying glass, one observes a minute granulation near the antero-lateral and on the postero-lateral margins, on the frontal teeth, on the upper margin of the orbits and on the epigastric lobes. In both species, immediately behind the frontal teeth of the second pair, a small tubercle is present; this tubercle is less cons- picuous, more rounded in the species described by Bianconi. The general shape of the chelipedes is the same in both and even as regards the form and the toothing of the fingers , M. Fornasinii agrees with M, granulosa. These legs, however, are everywhere quite smooth in Bianconi's species, but conspicuously granulated in M. granu- losa, as has been described in my Report on the Crustacea of the Mergui Archipelago. The chelae of M. Fornasinii appear, however, distinctly punctate to the naked eye; these puncta are more numerous and somewhat larger on the upper margin of the palm than on its convex outer surface and between them a much finer microscopical punctulation is moreover observed, when the legs are exa- mined under a strong lens.

to dedicate to Dr. A. E. Ortraann of Princeton N. J.,the author of so many important carcinological memoirs, bears such a striking resemblance to Menippe Panope Herbst from Tranquebar that I thought it necessary to send this specimen to Prof. Hilgendorf at Berlin, who kindly com- pared it with the type of Herbst, also a female, and then indicated to me the differences, so that this species, an inhabitant of freshwater, proved to be new to science. The cephalothorax has exactly the same width and length as the type of Menippe Panope^ so that the new species is probably also one of small size and the general shape of the carapace is the same. Prof. Hilgendorf informed me that both species also agree with one another as re- gards the convexity and the outline of the cephalothorax. The greatest width, at the tips of the penultimate antero- lateral teeth, is not yet once and a half as large as the length , measured in the middle. The cephalothorax is strongly convex fore and aft, somewhat less from side to side. Just behind the middle one observes the usual H-shaped figure, that is not formed by furrows as usual, but only by the absence of the minute granules with which the whole surface of the cephalothorax is covered. The regions are inconspicuous, not at all defined, for besides the H-shaped figure only the meso- gastric furrow is to be observed, and even the lateral branches of the cervical groove, the boundary between the gastric and branchial regions, are completely wanting. A little before each anterior extremity of the H-shaped figure, I observed an impressed point, corresponding to the posterior extremity of the protogastric areae. An imaginary line that unites these two points, crosses the lateral margins about in the middle between the tips of the two posterior antero- lateral teeth and the distance between this line and the frontal margin measures almost two thirds of the distance between it and the posterior margin of the cephalothorax. Just as in Menippe Panope., the two epigastric lobes are lying at some distance behind the free border of the front,

Notes from the Leyclen Museum , "Vol. XXI.

62 CRUSTACEANS OF THE

between the orbits; these lobes are declivous forward and towards the orbits and are separated from one another by the meso<^astric furrow that, after bifurcating, extends only over the anterior fourth part of the cephalothorax. In Menippe Panope, however, the interregional groo- ves are well-defined, though Hilgendorf informs me that they are less conspicuous than in Herbst's figure. The whole upper surface of the cephalothorax shows, under the lens, an extremely fine and close microscopic granu- lation, but it appears smooth to the naked eye; only just near the penultimate autero-lateral teeth these minute granules are a little larger, though still only visible by means of a magnify ing-gl ass. The anterior moiety of the cephalothorax of Menippe Panope, however, is covered anteriorly and on the a n ter o-later al regions with numerous red pearly granules at least twice as large as the microscopic granules described above and observed also on the species from Tranquebar. Such large granules are observed, in Menippe Orimanni, only on the front, just behind the free border, so that they are already fully wanting on the epigastric lobes. On each side of the upper surface of the cephalothorax one observes six or seven impressed points, situated in a semicircular line, that runs from the impressed point des- cribed above, just before the ends of the H-shaped figure, to the extremity of the ridge of the last antero-lateral tooth. The upper surface is also somewhat pitted on the front, just behind the supra-orbital margins and near the autero-lateral border of the carapace.

The front is obliquely deflexed and as prominent as in Menippe Panope ; it is cut by a rather deep trian- gular notch into two obtuse lobes. The granulated fore edge of these lobes shows at its outer angle a small ob- tuse tooth before passing into the supra-orbital margin, so that the front may be described as four-lobed; these small external teeth reach about as far forward as the inner lower angle of the orbits and form an obtuse angle

Notes from tlip Leyden JVIuseum , Vol. XXI.

nurCH BORNEO-EXPEDITION. 63

with the upper margin of the orbits; the distance between these two obtuse angles, i.e. the width of the front, mea- sures a little less than a third of the greatest breadth of the cephalothorax.

The distance between the outer angles of the orbits is little more than half the greatest width ; these angles are dentiform, but small and not very conspicuous. The finely granulated supra-orbital margin is tumid, well delimited from the carapace, with two distinct grooves near the outer angle. The orbits are almost circular, scarcely broad- er than high. Immediately below the outer angle there is a small triangular groove or gap; the lower margin of the orbits is concave in the middle and both its inner and its outer angle are dentiform, the former being larger and projecting more forward than the latter. This external lobe or angle of the infra-orbital margin (Fig. and 2*) is a little larger than the extra-orbital angle and a little more prominent.

The fairly sharp, finely granular antero-lateral margin of the carapace is about as long as the postero-lateral and divided into four teeth, the first three of which are broad and anteriorly acuminate, the last narrow and carinated ; these teeth are, however, lower and less pro- minent than in Menippe Panope Herbst, as Hilgendorf writes. The distance (1^/2 mm.) between the outer angle of the orbit and the tip of the first antero-lateral tooth measures three fourth the distance between the tips of the two first teeth and this latter measures two thirds of the distance between the tips of the second and third tooth ; the tip of the third tooth finally is still slightly more distant from the fourth than from the antepenultimate. The four first teeth therefore, including the extra-orbital angle, gradually increase in length. The outer margin of the penultimate tooth runs backward and slightly inward, so that the cephalothorax presents its greatest width at ■the tips of these teeth ; the last tooth is carinated above and the ridge that gradually diverges from the postero-

lateral border , is nearly as long as the outer margin of the penultimate tooth. Just as in Menippe Fanope, the straight postero-lateral borders strongly converge backward, so that the slightly concave posterior margin ofthecepha- lothorax is scarcely as wide as the front.

The basal joint of the external antennae is small and even slightly more distant from the front than it is itself long; the second, much smaller joint reaches scarcely the front and the third joint is narrower than the orbital hiatus ; unfortunately the flagellum is broken , but it is certainly as long as the orbits are broad. The internal antennae (Fig. 2*) are a little oblique , the epistome is short. The endostome is faintly ridged, the ridges being only distinct on its posterior part.

The external maxillipedes (Fig. 2^) are covered every- where with a close microscopic granulation and a few fine hairs are distributed over them ; they have about the same form as those of Menippe Rumphii from the Indian Ocean.

The fore edge of the merus-joint is slightly convex, the antero-external angle is obtuse and the outer margin is somewhat concave.

The whole under surface of the carapace, between the lateral margins and the buccal frame, presents the same close microscopic granulation as the upper surface; the granules on the internal infra-orbital lobe are a little larger and near the lower border of the orbits the surface is somewhat pitted (Fig. 2''').

The abdomen of the female is a little broader than that of Menippe Panope , it presents its greatest width at the penultimate joint and the terminal joint is semi- circular; the seven joints are quite smooth, though some- what pitted near their lateral- and anterior margins.

The chelipedes difler from those of Menippe Panope es- pecially by their different granulation. They are, as in Herbst's species , massive and unequal , the right being the larger. The strongly curved upper margin of the quite short arm of the right leg, which scarcely extends

beyond the lateral margin of the carapace, is rather sharp and unarmed ; the aaterior margin is less sharp and the lower border is rounded. The smooth inner surface of the large massive wrist fits close to the antero-lateral border of the cephalothorax and its inner angle is bluntly pro- minent. To the naked eye the upper and the outer sur- face of the wrist appear smooth and shining, but under a lens one observes just the same close micro- scopic granulation as on the surface of the carapace ; in Menippe Panope Herbst, however, granules of large size, similar to those of the outer surface of the hands, are distributed over about three fourth parts of the convex upper surface of the wrist. Near the anterior margin, that articulates with the hand, the granules are a little larger. The upper surface of the wrist is moreover somewhat pitted. Hilgendorf writes me that the hand of the larger leg is one millimeter longer and a little lower than that of the type specimen of Mejiippe Panope Herbst, so that the shape of the hand is not exactly the same. The length measured horizontally is a little shorter than the greatest width of the cephalothorax and the hand is almost twice as long as high. The fingers are somewhat less than half as long as the whole hand, measured horizontally. The lower margin of the palm makes a straight line with that of the immobile finger.

According to a former information received from Prof. Hilgendorf, the granules on the middle of the outer surface of the hand are, in the species described by Herbst, ^j^ mm. broad and dis- tinctly larger than those of the upper and of the lower margin (confer: de Man, The Journal of the Linnean Soc. of London, V. 22, 1888, p. 43). In the specimen from Sanggau, on the contrary, the convex outer surface of the larger chela is covered with a not quite uniform granulation, distinctly visible, however, to the naked eye ; this granulation is somewhat closer near the upper and near the lower margin of the palm than in the

middle of the outer surface. On the middle the gra- nules have but a diameter of ^/^ mm., near the upper margin and at the base of the immobile finger they are a little larger, being '^j^ mm. broad. Under a lens I observe moreover a close micro- scopic granulation on the whole outer and inner surface of the palm, as also on the lower border on which the larger granules are absent.

The outer surface of the immobile finger shows a longi- tudinal furrow near the lower margin and a shorter one at the base of the teeth, and the granulation disappears gradually towards the obtuse tip (Fig. 2'*'); this finger bears just in the middle a strong conical tooth, on either side of which two smaller teeth are observed. The strongly curved dactylus is granular at the base and bears two rows of impressed puuctures; this finger is also bluntly pointed and is armed with 7 or 8 low, obtuse teeth. The left hand is considerably smaller, its horizontal length measures indeed only two third of the greatest breadth of the cephalothorax and this hand is a little more than twice as long as high. The fingers are almost as long as the palm and more sharply pointed at their tips. The immobile finger carries five incisiform teeth that gradually decrease in size, the dactylus is less curved, distinctly grooved and its teeth are also incisiform, but lower than those of the index. The outer surface of the palm is rather uniformly covered with granules, all of about the same size, ^4 ^t^- broad, and between these granules one observes under a lens the microscopic granulation. The lower border of this hand is a little concave in the middle. The wrist and the arm agree with those of the other leg, also with regard to the granulation.

The short ambulatory legs resemble those of Menippe Panope. Their joints are smooth on the outer surface, only a little punctate, but their anterior margin is finely granular ; the margins are a little hairy, mostly those of the terminal joints that end into sharp horny claws.

The fingers of the chelipedes are dark brown, excepted at the base, with white tips. The cephalothorax, preserved in alcohol, has a light yellowish brown hue, without a trace of the small red spots with which Menippe Panope is mottled.

Menippe convexa Rathb., from Honolulu, seems to be a closely allied species, but the anterior portion of the rae- sogastric region is defined and the median lobes of the fi'ont are small, separated by a shallow groove, characters not observed in Menippe Ortmanni. The habitat is more- over quite different.

6 specimens (2 cf cf, 4 $?) without definite locality though probably from Sintang.

2 males and 1 female from the southern foot of Mount Kenepai, collected in December 1893.

2 young males from Nanga Raoen.

2 young males from the forest near the small Siniai river, captured in March 1894, and finally

1 young female collected by Dr. Nieuwenhuis at Bloe-oe, a locality situated on the Upper Mahakkam.

Not one of all these specimens may be considered to have attained its full growth : the cephalothorax of the largest individual, a male from Mount Keuepai, is 49 mm. broad, but the female from the Solor-Islands, that has been mentioned in my paper quoted above, was 70 mm. broad. The proportion between the width and the length of the cephalothorax appears to be somewhat variable in this species. In the specimen figured by Milne Edwards (1. c.) the proportion is as 23 : 19. Just the same pro- portion is shown by the female from Sanggau and by a younger female from Buitenzorg, .Java, in my own col- lection; in both the form of the carapace fully agrees with the figure in the » Archives du Muséum." In all the other specimens, however, the cephalothorax appears a little broader, the proportion between width and length being as 23 : 18. In the old female from the Solor-Islands the cephalothorax was 70 mm. wide and 52 mm. long, the proportion between both therefore as 23: 17, but this may be a consequence of the large size of this specimen.

Almost in all those individuals in which the proportion between width and length of the cephalothorax is as 23 : 18, the tip of the first epibranchial tooth is a little less distant from the external orbital angle than from the tip of the second epibranchial tooth, that seems to be usually the case in this species (de Man, 1. c. p. 64) ; in the female from Sanggau, however, as also in that from Buitenzorg, the cephalothorax of which specimens is less enlarged, the distance between the tips of the two epi-

branchial teeth appears a little shorter than the dis- tance between the tip of the first epibranchial tooth and the outer angle of the orbits. I presume that these both characters coincide.

Von Martens (1. c.) says that in his specimens from Borneo the extra-orbital tooth presented a »zwar abgerun- deten und stumpfen , aber doch deutlich begrenzten Vor- sprung", that he considered as homologous to the first epibranchial tooth of Parathelphusa sinensis. In the spe- cimens now lying before me no trace of such a promi- nence is perceptible.

According to the same author the penultimate segment of the male abdomen should be about once and a half as long as broad, but in the present specimens it is but slightly longer than broad. In the older specimens the lateral margins of that segment show a small blunt prominence (Fig. 3), so that it appears here broadest; behind these prominences the lateral margins run parallel with one another. In the largest male, that from Mount Kenepai, the penultimate segment (Fig. 3) appears at the two prominences only for one ninth part, and behind them for one sixth less broad than it is long.

In two specimens without definite locality, viz. in the male specimen 4, measured below, and in a female, the ambulatory legs are a little more slender as is ordinarily the case : this species therefore varies also in this character.

Cephalothorax and legs of most specimens have a dark olive-green colour, sometimes with a reddish hue, as espe- cially in the female from Sanggau ; the fingers are darker, often blackish with reddish yellow tips.

Perithelphusa, n, subg.

I propose this nevt^ subgenus for Potamon borneense v. Mart, and two new species described in this Report. It is characterized by the existence of one single, well- developed, acute, spiniforra epibranchial tooth, and by the post- frontal ridge being as little developed as in the subgenus Geothelphusa . In these three species the male abdomen has the same form, its sides converging from the base of the third to the apex of the fifth seg- ment, thence to its extremity narrow. The meropodites of the clifilipedes bear a sharp spine on their superior margin, just behind the distal extremity ; the lower sur- face of these joints is smooth, without a tubercle near the carpal articulation and having the margins entire, not tubercular.

This new subgenus forms a remarkable transition to

Notes Iroin the Leytleii INlusieum, Vol. JXXI-

DUTCH BORNEO-EXPEDITION. 71

the subgenera Parathelphusa and Geothelplmsa. It difiers from the former by the existence of only one single epi- branchial spine and by the absence of a postfrontal ridge, for in Parath. spinigera White, the only form with one epibranchial tooth, the lateral portions of the postfrontal crest are well-developed and sharp. Perithelphusa may be distinguished from Geothelphusa by the well-developed epi- branchial spine and by the existence of a spiniform tooth on the upper angle of the arms of the anterior legs.

Five specimens (3 cfcT, 2 99) were collected by Max Moret at Sintang.

The two females, though adult, carry no eggs.

This interesting species bears some general resemblance to Parath. spinigera White from Calcutta, but differs by the absence of the postfrontal ridge. It appeared to me probable that either this species or one of the two follow- ing might belong to Potamon borneense v. Mart., and therefore one male specimen of each was sent to Prof. Hilgendorf at Berlin, who, after a close examination, wrote me the following about the species which 1 go to describe: »Diese Form kann zur Noth mit T. borneensis zusaramen- gebracht werden. Ich würde aber doch jedenfalls eine Varietat daraus machen". The individuals described by von Martens have been collected near Seminis in the Sampas- basin and at Lempai near the lake of Danau Sriaug, in the Upper-Kapoeas-basin, in the same region therefore as our specimens. The specimen sent to Berlin, was the male 2.

is one third broader than that described in the » Archiv fur Naturgeschichte". As is proved by the measurements, the proportion between the greatest width and the length of the cephalothorax is somewhat variable in our speci- mens , but in all these the cephalothorax appears, however, slightly more enlarged than in the type with which our specimen was compared. The carapace is little en- larged, the greatest width is in proportion to the length as 4:3 and is observed just behind the epibranchial teeth, on the limit of the foremost third of the upper surface. The upper surface is somewhat convex from before backwards, less so, although still distinctly, from side to side. The mesial cresceutic portion of the cervical groove is distinct and moderately deep, excepted just in the middle, but the lateral portions are inter- rupted (Fig. 4) ; the median part of the semicircular groove is just twice as far distant from the free border of the front as from the posterior margin of the carapace. The anterior lateral portions between the gastric region and the anterior branchial one are two rather deep, oblique furrows, that in the adult end about 4 mm. short of the notch that bounds the epibranchial tooth anteriorly. A post- frontal crest cannot be said to exist as it is only represented by the wrinkled and rugose slope, with which the gastric region subsi- des towards the front and the post-orbital furrow. The epigastric portion, however, is more or less distinct and slightly bent forwards; the mesogastric furrow is linear, very narrow and shallow, not con- tinued on to the front nor backwards and not bifurcating, so that the anterior extremity of the mesogastric area, in other species well-defined, is not at all distinct.

The anterior branchial region is moderately swollen, scarcely marked off from the posterior one; shallow depres- sions separate the posterior branchial and the cardiac re- gions from the intestinal, but the cardiac region is scar- cely limited off laterally. The small, somewhat wrinkled

urogastric areolets are not contiguous, but separated ft'om one another by an interspace almost as broad as the areo- lets themselves.

The upper surface of the carapace appears under a lens very finely punctate, the punctation is rather close, some- what less so on the cardiac and mesogastric areae than elsewhere; on the front and behind the orbits the puncta are coarser. The gastric region is quite anteriorly, as well on the epigastric lobes as on the slope towards the post- orbital furrow, distinctly wrinkled and foveate. The lateral margin of the cephalothorax is covered, from the epibranchial tooth till the posterior margin, with oblique raised lines and is posteriorly slightly concave. For the rest the surface of the cephalothorax appears smooth and shining to the naked eye.

The front is obliquely deflexed, the anterior border is straight in the middle, or, as in the youngest male and in the youngest female, very slightly concave. In the type described by von Martens the free border is a little curved upward, so that the upper surface of the front appears slightly concave; this is also the case in the youngest male, but in the other specimens not or scar- cely so. The free border curves into the very oblique inner somewhat raised portions of the upper orbital margins, or the frontal angles are at least very obtuse and rounded; the frontal margin measures about one fourth the greatest width of the cephalothorax, it is somewhat difficult to measure exactly its breadth, ac- cording to von Martens, however, one third. The distance between the free border of the front, near its outer angles, and the epigastric lobes is scarcely half as long as the former is broad. The front appears considerably broader at its base than at its free border.

The external orbital angles are moderately sharp and reach as far or almost as far forwards as the free border of the front, but not beyond it; the distance between them measures three fourth or little more than

three fourth the length of the cephalothorax. The outer margin of the extraorbital tooth makes a right angle with the upper margin of the orbits. The epibranchial tooth or spine, directed straightly forward or slightly in- ward, is, as in Parath. spinigera, widely distant from the external orbital angle, the distance between the latter and the tip of the epibranchial spine measuring about one fourth the whole length of the lateral margin. The base of the epibranchial tooth is about as far distant from the outer angle of the orbits as the epistome is broad, but in the type of von Martens the epistome is somewhat broader than that distance.

The epibranchial spine is strong, acute and sa- lient, has a black point and is bounded anteriorly by a deep notch. The slightly sinuous outer margin of the extraorbital tooth makes with that notch an obtuse rounded angle, but in the type described by von Mar- tens this angle is less distinctly marked on one side, faintly so on the other, the margin curving more regu- larly towards the base of the tooth. The posterior margin of the cephalothorax which is a little concave is, in the adult, almost twice as broad as the free border of the front, in the younger specimens somewhat shorter.

The small orbits (Fig. 4«) are almost transverse, they are once and a half as broad as high and their width measures two thirds of that of the frontal margin. The outer margin of the extraorbital teeth, the upper and the lower margin of the orbits and the free border of the front are smooth, entire. The somewhat sinuous infraorbital margin has no hiatus near the outer angle and the obtuse inner angle is small, little prominent: the inter- space between this angle and the front is wide. According to Hilgendorf the cornea of the eye-peduncles should be slightly larger and the distance between the free border of the front and the posterior margin of the epistome somewhat shorter than in the Berlin type: in the adult specimens this distance is half as long as the free border

of the front is broad. The anterior margin of the epistorae, the surface of which is smooth , is as far distant from the frontal margin as from the tip of the triangular pro- cess that the posterior margin of the epistome sends back- wards and downwards ; on either side of this median tooth , the smooth posterior margin shows still another smaller, less prominent tooth, so that it is twice notched on each side.

The subhepatic area is limited ofi from the branchial floor by a finely granular transverse line and both regions are beset with oblique raised lines or rugae, that are also finely granular and as usual reach to the postero-lateral margins. The groove between the hepatic region and the branchiostegite is rather deep, especially anteriorly; one observes on the latter, near that groove, a few oblique rugations, but it is for the rest smooth.

The ischium-joint of the outer foot-jaws appears finely punctate under a magnifying glass, the longitudinal furrow on it is deep and runs close to and parallel with the inner margin. The merus-joint is some- what broader than long, its antero-external angle is obtusely rounded ; this joint appears also punctate under the lens and somewhat rugose at its postero-external angle, the punctatiou , however, is in some individuals rather indistinct.

The sternum and the abdomen of the male are smooth , though appearing finely punctate under a lens. There is at the anterior extremity of the sternum, between the pos- terior margins of the maxillipedes, a transverse fur- row or impression, but there are no ridges on the sternum near the insertion of the chelipedes. In this species the distance between the anterior extremity of the ischial furrow and the outer margin of the ischium-joint appears a little broader than the distance between the anterior extremity of the abdominal cavity and the posterior margin of the buccal frame. Prof. Hilgendorf made me acquainted with this character.

The male abdomen bears some resemblance to that of Potamon (Geothelphusa) loxophthalmufn, de M. (deMan,in:

Notes from the Leytleu Museum, 1892, pi. 9, fig. 3 c). The terminal joint is obtusely rouuded and the sides are slightly concave. The sixth segment is a little longer than the seventh, the straight anterior margin is just as broad as the concave posterior one and measures little more than two thirds of the length of the joint, so that the latter is almost once and a half as long as broad. Just be- hind the anterior margin, the sides of this segment slightly bulge out laterally, so that it shows here its greatest breadth and in the type of Berlin the sixth joint is very slightly shorter than in our specimens. The antepenultimate joint is a little more than half as long as the sixth and exactly half as long as the posterior margin of it is broad. The closely punctate abdomen of the female has the usual form, the posterior border of the terminal joint is 2^1^ times as broad as this joint is long.

The chelipedes are greatly unequal in the males , but subequal in the female (the younger female has lost all its legs) and in all the right leg is the larger. The arms project but little beyond the lateral margin of the cephalothorax. The upper edge is rugose and bears, just behind the constriction at its distal end, a sharp spine as usual in this subgenus; in the type examined by Hil- gendorf it appears less slender, but it is probably worn oö, as is also the case on the larger chelipede of the youngest male. The outer surface is covered with transverse rugo- sities, but the lower is smooth and bears no tooth or spine near the anterior margin; the anterior and the ventral angle are not rounded off, as is the case in Parath. spinigera. The upper surface of the carpopodites is faintly rugose and appears finely punctate under a lens; these joints are armed with a single stout spine at the inner angle. In the adult male the larger chela, measured horizontally, is just as long as the cephalothorax is broad, but in the younger males one fourth shorter. The fingers, measured horizontally, are as long as, but never shorter than" the palm, that is almost just as

high as long. The lower margin of the palm is contex and makes thus no straight line with the index. The con- vex outer surface of the palm is covered with extremely shallow, small depressions or foveae, giving it a reticu- late appearance and the interspaces between them show, under a magnifying, glass, a minute granulation; one observes under a lens also a fine punctulation , more distinctly in the younger males than in the adult. The sliglitly compressed fingers are moderately slender and leave, in the adult, a narrow interspace between them when closed ; they are covered, from their base untill the pointed extremities, with an extremely fine and close granulation, hardly visible to the naked eye. The fingers are not at all grooved, the fine puncta, however, are arranged more or less distinctly in longitudinal rows. The dactylus is somewhat curved and both fingers are multidentate; the immobile finger (Fig. 4^^) is armed with about 20 small conical and unequal teeth of which the fifth and the eighth are somewhat larger and more prominent than the others. The teeth of the dactylus are a little smaller, also unequal, one in the middle is larger than the rest.

The smaller chela of the adult male is, horizontally measured, just as long as the cephalothorax and twice and a half as long as high ; the fingers are a little longer than the palm, in contact throughout their length and the dactylus is less curved. In its other characters this hand agrees with the other.

Unfortunately in the adult female the immobile finger of the right hand, that is but very slightly larger than the other, is broken off and in the other female all legs are lost. The hands are much smaller than in the male, the horizontal length of the right chela measures three fourth the length of the carapace , the other is only 2 mm. shorter ; the fingers of the right hand are about as long as the palm, in the other they are slightly longer. The teeth are smaller, but for the rest they resemble the hands of the male.

the larger chela is less stout and palm and fingers are less high than in our specimens, but the type has a smaller size, as was already observed. The ambulatory legs are of moderate length, so e. g. those of the penultimate pair of the adult male are 60 mm. long, i.e. almost once and a half as long as the cephalothorax is broad; the meropodites are nearly three times as long as broad, their outer surface is granular, their upper mar- gin is rugose and provided near the distal end with a sharp spine. The propodites of the penultimate legs are in the middle scarcely half as broad as long and in the adult the dactylopodites are somewhat longer. The ambulatory legs are glabrous. In the type these legs appear, as Prof. Hilgendorf wrote to me, a little more slender. The cephalothorax of our specimens preserved in alcohol, has above an olive-green or yellowish-green colour and is mottled with innumerable small red spots, the fronto-orbital margin and the epibrancbial tooth are yellow. The chelipedes and the other legs present above the same green colour and spots, but on the chelipedes the latter are a little larger than on the carapace. The lower surface of the latter and of the legs is yellow and devoid of spots. In the type specimen at Berlin the small red spots are completely wanting.

Parathelphusa spinigera 'Wh.xie {Qoniex: Wood-Mason, in : Journal Asiatic Soc. of Bengal, Vol. XL, Pt. II, 1871, p. 194, PI. XII, Figs. 1 4) bears some resemblance to Po- tamon borneense, but is certainly different. I studied two specimens of that species during my last visit to the Bri- tish Natural History Museum in 1896. The cephalothorax is more enlarged, that of an adult male from Calcutta is 59 mm. broad and only 39 mm. long. The post-frontal ridge is better defined , its lateral portions especially are cristiform and sharp ; the free border of the front is slightly concave. The male abdomen has a different form, the penultimate or sixth joint is more quadrate, for in the adult male from Calcutta, that 1 examined, it is 8 '/a mm.

long and the anterior and the posterior margins are re- spectively 6^/2 mm. and 7^/4 mm. broad. The immobile finger of the larger chela has a different shape, being higher at the base and the meropodites of the ambulatory legs bear no spine near the distal end of their upper margin.

Potamon {Perithelphusa) Biittikoferi, n. sp.

(Plate 6, fig. 5).

Four males of difi'erent size from Sintang, collected by Max Moret.

This new species bears some resemblance to the prece- ding one: the meropodites of the ambulatory legs present a spine on their anterior margin and the upper angle of the arm of the chelipedes also, the abdomen has about the same form and as regards the postfrontal ridge , as little defined , both species agree with one another. There- fore this species, that I have the pleasure to dedicate to the Zoologist of the Expedition, may be likewise referred to Perithelphusa. The second male has- been compared by Prof. Hilgendorf with the type of Potamon horneense v. Mart, and he wrote me that he considered this species to be new.

As in Pot. horneeyise v. Mart. var. hilaris, the greatest width of the cephalothorax is in proportion to its length as 4:3, but the distance between the epibran- chial teeth and also that between the outer orbital angles are in proportion to the great- est width a little shorter and as the lateral margins have a different form and direction, the cephalothorax of both species presents a different shape and figure.

As regards the convexity of the carapace, as well from end to end as from side to side, both species almost agree with one another; in the largest specimen the gastric region appears slightly less convex transversely but this may be an individual difference. Concerning the little deve- lopment or rather absence of a post-frontal ridge, both also agree with one another; it is only indicated by the slope, by means of which the gastric region subsides to- wards the front and towards the post-frontal furrow. The epigastric lobes are slightly advanced, wrinkled anteriorly, not limited off posteriorly, but continuous with the gastric

region ; the declivous lateral parts are coarsely punctate, scarcely wrinkled. The cervical groove is interrupted, just as in the preceding species and in both equally far dis- tant from the anterior margin of the front ; the posterior, median, crescentic portion is deep, the anterior portions are just as deep as in Pot. borneense var. hilaris, hut iheiv direction is less oblique: these furrows, indeed, when continued backwards would form a right angle with one another in the preceding species, but an acute one in Potamon Büttikoferi. The gastric region is not subdivided and even the anterior prolongation oftheraeso- gastric area is not defined, the mesogastric furrow being short and not bifurcating; the antero-external parts of the gastric region appear, in the adult, somewhat wrinkled, the ramifying wrinkles diverge from the anterior branches of the cervical groove, in the younger individuals these wrinkles are less conspicuous. The urogastric areolets agree with those of Pot. bornemse^ and shallow depressions sepa- rate the anterior branchial lobe from the posterior one, that is considerably smaller, and the latter from the cardiac region.

The front presents distinctly a broad, shallow bay that extends till the rounded lateral angles, which pass with a curve into the upper margin of the orbits, so that it is here also somewhat difiicult to measure exactly the breadth of the free border of the front: it is about one fourth the greatest width of the carapace. The somewhat raised lateral margins of the front are slightly less oblique than in Pot. hor^ieense var. hilaris^ so that the front appears at the base a little less broad in proportion to the width of the frontal anterior margin. Just before the foveate epigastric lobes the surface of the front is marked with a few transverse rugosities, but for the rest it is coarsely punctate. The supra-orbital margins are sinuous and form almost right angles with the outer margin of the extraorbital tooth ; the outer angles of the orbits are moderately sharp and reach almost as far forward as the

free border of the front. The epibranchial teeth are wi- dely distant from the external orbital angle, though the distance between the latter and the tip of the epibranchial tooth is a little shorter than in the preceding species, measuring in the adult male one sixth the length of the whole lateral margin. The outer border of the extraorbital tooth is in most specimens almost straight, with no ob- tuse angle in front of the notch that separates it from the epibranchial tooth ; the third male, the carapace of which is 30 '/a ïUQi- broad, resembles, however, in the form of this outer border, Pot. borneense var. hilaris. The epibranchial tooth is acute, with a brown point, directed forward and slightly inwards, but these teeth are some- what smaller than in the other species. Otherwise as in the latter, in which the distance between the epibranchial teeth is almost as large as the greatest width of the ce- phalothorax, the lateral margin runs, behind the epibran- chial tooth, obliquely outwards so that the branchial lobe bulges out laterally with a convex outer margin; the greatest width of the cephalothorax is situated along a line dividing the anterior from the middle third of the upper surface. The oblique raised lines on the slightly concave postero-lateral margins are a little less nume- rous but more salient than those of the variety hilaris of the preceding species. The whole upper surface is finely and closely punctate, on the cardiac and mesogas^vic areae the minute puncta are less numerous. The posterior margin of the cephalothorax is, at least in the adult male, i. little less broad with regard to the greatest width of the cepha- lothorax than in Pot. borneense var. hilaris.

The orbits are small, slightly oblique in a front view and little broader than high; in a front view the sinuous course of the upper margin is well visible, the lower margin is regularly curved, without a notch or hiatus near the outer angle and the obtuse inner angle is very small, scarcely prominent and widely distant from the front.

The nasal plate is somewhat broader, but less

high than in the preceding species, the epistome has about the same form, but the median tooth is obtuse. As in that species the subhepatic region is limited off from the branchial floor by a distinct transverse furrow and with regard to the wrinkles and rugosities on the lower surface of the cephalothorax both species agree.

The ischial line of the external maxillipedes has the same situation and direction as in the preceding form and also with regard to their other characters the outer foot- jaws agree, but the merus-joint is slightly less en- larged with regularly rounded anterolateral angle.

In the male of Pot. borneense var. hilaris the abdominal cavity reaches as far forwards as a line uniting the outer angles of the buccal frame and there are no impressions or only very slight ones between these angles and the end of the cavity ; in Pot. Büttikoferi, however, the cavity reaches not so far forwards and the sternum bears, just before its extremity, a rather deep transverse fur- row between the outer angles of the buccal frame, in front of which one sees, in the angle of the sternum, the same transverse groove that also exists in Pot. borneense var. hilaris^ and equally there are no ridges near the insertion of the chelipedes. The distance between the an- terior end of the ischial line of the external maxillipedes and the external margin of the ischium is a little shor- ter than that between the anterior extremity of the ab- dominal cavity and the oblique posterior margins of the buccal frame, in Pot. borneense var. hilaris, however, a little broader. The sternum is smooth, punctate. The male abdomen has the same form as in the preceding species, but the penultimate segment is comparati- vely shorter, being but very slightly longer than the terminal ; the lateral margins have the same form and direction in both and the punctation is the same.

The chelipedes are very unequal, in the largest male the left is the larger, in the others the right. The meri project as little beyond the carapace as in Pot. borneense,

the upper margin carries a rather small spine or tooth, that is acute in the two youngest individuals, but worn off in the two others. For the rest the meri resemble those of Pot. borneense, the angles of the flattened lower surface being moderately sharp, not rounded and this sur- face presenting no trace of a spine or tubercle. The wrist carries above oblique rugosities and wrinkles and is armed at the inner angle with a rather short, but stout spine. In the largest specimen the large chela is almost as long, measured horizontally, as the cephalothorax is broad, in the others it is comparatively shorter, so that in the youngest individual it measures only two thirds of the greatest width. In the adult male the somewhat compressed fingers that leave an interspace between them, when closed, meeting only at the pointed tips, are almost once and a half as long as the palm; they have about the same height, in Pot, borneense var. hilaris, however, the index is higher at the base than the dactylus. This finger is armed near the articulation with a strong tooth, that bears a few smaller ones and between this tooth and the extremity 9 or 10 very small teeth are observed. The somewhat curved dactylus carries in the middle a conical tooth, much smaller than the strong tooth of the immobile finger and a few very small teeth stand on either side of it. The fingers are smooth, punctate, on the middle the puucta form a longitudinal row. The con- vex palm is, at the articulation of the fingers, a little higher than it is long, measured horizontally ; it appears smooth to the naked eye, but presents under a lens the same structure as the palm of the larger hand of the pre- ceding species. The lower margin of this chela is slightly concave in the middle.

In the younger males the fingers are as long as the palm, that is about as high at the articulation of the fingers as it is long; the fingers are almost in contact with one another, the toothing is about the same as in the adult. The longitudinal rows of puncta are still more distinct, so

that the fingers appear faintly grooved. Under a strong lens a similar close and fine granulation is shown by Pot. borneense var. hilaris, the palm presenting fine reticulating lines that are minutely granular.

The smaller hand of the adult male measures scarcely three fourth the width of the cephalothorax, the fingers are but little longer than the palm and almost in contact with one another. In the younger specimens the smaller chela is still shorter, so in the youngest male ifc is little more than half as long as the cephalothorax is broad.

The ambulatory legs are comparatively as long as in the preceding species and are also quite glabrous, but they are more slender. So e. g. the legs of the penultimate pair are almost once and a half as long as the cephalo- thorax is broad, measuring 56 mm. in the adult male. The upper margin of the meropodites terminates into an acute tooth and the outer surface is granular, excepted those of the last pair ; they are slender, so e.g. those of the penultimate pair are a little more than 3 times as long as broad, the propodites are 2'/2-times as long as broad, in the middle, and the stout terminal joints are somewhat longer than the propodites. The upper surface of carapace and legs is mottled with similar small spots of a red colour as in Pot. borneense var. hilaris.

Potamon (Perithelphusa) silvicola, n. sp. (Plate 7, Fig. 6).

Four males about of the same size aud two youoger females without eggs, were collected in March and May 1894 in a forest near Nanga Raoen and in the following month one quite young male was captured at Poetoes Sibau.

This species is closely allied to Pot. borneense v. Mart, and its variety hilaris, and bears a great resemblance to them, but it differs more from Pot. Bilttikoferi, at first sight by the different general outer appearance. It may be distinguished from the first named species and its va- riety especially by the cephalothorax being a little longer in proportion to its greatest width, by the different shape and length of the extraorbital teeth.

The third specimen, the carapace of which is 32 '/2 mm. broad, was sent to Prof. Hilgendorf at Berlin, who com- pared it with the type of Pot. borneense v. Mart, and then wrote me the differences.

The carapace is little enlarged, being little longer than three fourth the greatest width and it is constantly so-

mewhat less enlarged than the cephalothorax Pot. borneense and of the variety hilaris. Tlie upper surface is a little less convex in the antero-posterior direction than in Pot. borneense var. hilaris and the posterior half viz. the cardiac and intestinal regions together with the con- terminous parts of the undivided branchial region, appears rather flattened from side to side. The cervical groove is interrupted and the oblique anterior furrows have the same direction as in Pot„ borneense var. hilaris^ for they would make a right angle with one another, when prolonged backwards. The postfrontal ridge is as little developed as in Pot. borneense ; the slightly advanced epigastric lobes, that are foveate anteriorly, smooth above and not limited off posteriorly from the gastric region, are well-defined, but on each side of them one observes, as in the two preceding species, only the rugose and coarsely punctate slope by which the gastric region subsides towards the post-orbital furrow. The mesogastric furrow is short and narrow, the anterior end of the meso- gastric region is therefore not defined. The upper surface is finely punctate, rather closely on the branchial, cardiac and intestinal regions, but on the gastric region the puncta are less numerous ; they are visible to the naked eye, the carapace, however, appears smooth and shining. The shallow depressions that bound the cardiac region are often in- distinct.

The front resembles that of Pot. borneense var. hilaris. The free border measures one fourth the width of the carapace and is straight, not bayed at all; the lateral margins of the front have the same oblique direction and form obtuse angles with the anterior margin. Prof. Hil- gendorf informs me that in the type of Pot. borneense these angles are more rounded off, so that the anterior frontal margin appears narrower, von Martens indeed says that it measures one third the width of the cephalo- thorax. As in the other form the mesogastric furrow is not continued on the front. The front is flattened, not

concave, the free border being not curved upwai'd ; the surface is somewhat granular.

The upper margin of the orbits has the same form and direction as in Pot. borneense var. hilaris and is not si- nuous, as is the case with Pot. Büttikoferi; it forms a right or somewhat obtuse angle with the outer margin of the extraorbital tooth. The orbits and the eye-peduncles resemble those of the variety hilaris, the lower margin shows no notch near the outer angle, the inner angle is obtuse and little prominent. The external angles are ob- tuse and reach almost as far forward as the frontal margin ; they are comparatively a little less distant I'rom the epibranchial teeth than in Pot. borneense and its variety hilaris, so that the extraorbital tooth appears shorter. In the species described by von Martens the outer margin of the extraorbital tooth, from the outer angle of the orbits till the base of the epibranchial tooth, appears distinctly longer than the orbits are broad, but in Pot. silvicola just as long. The outer margin of the extraorbital tooth appears in most specimens slightly convex, but in others it has the same form as in Pot. borneense var. hilaris and the notch that separates it from the epibranchial tooth is just as deep. The epibranchial teeth are acute and salient, the lateral margin curves slightly outwards, so that it appears a little more convex than is usually the case in Pot. borneense and its variety. The oblique wrinkles are in both species numerous and moderately salient. The front-orbital and the lateral margins of the carapace are smooth, entire.

As regards the nasal plate, the epistome, the outer maxillipedes and the pterygostomiau regions, there is no difference between both species. As in Pot. borneense var. hilaris, the median tooth of the epistome is triangular, acute, there is also a granular line dividing the subhepa- tic from the subbranchial region and these regions as also the branchiostegite carry the same rugosities. The ischial

line of the external maxillipedes is jast as deep and has the same situation and direction.

The sternum shows another difference. Tn Pot. borneense and its variety hilaris the distance between the anterior extremity of the ischial line and the external margin of the ischium of the outer foot-jaws is always a little broader than the interspace between the anterior extre- mity of the abdominal cavity and the oblique posterior margins of the buccal frame ; in Pot. silvicola, however, these two distances are equally broad. The two transverse furrows on the sternum in front of the anterior extremity of the abdominal cavity are shallow.

The abdomen has the same form as in the species that was described by von Martens.

The chelipedes of the male are very unequal, in all the left is the larger ; they agree almost entirely with those of Pot. borneense var. hilaris. The upper margin of the meri bears near the distal end an acute tooth, which in the variety hilaris appears more spiuiform. The hands re- semble also those of this variety and present the same characters; the pointed fingers show, under a strong lens, the same minute granulation and rows of puncta, the toothing of the index is slightly different. The convex outer surface of the palm is smooth and shining, appears finely punctate under a strong lens, but the microscopic granulation is hardly perceptible. In the female the ante- rior legs are equal.

The ambulatory legs resemble those of Pot. borneense var. hilaris. The meropodites are granular on their outer surface except those of the last pair that are only punctate and their upper margin terminates into an acute tooth, the following joints are also similar in both species.

The cephalothorax of the males shows above a dark olive-green colour, marked with innumerable small spots; the margins are often ochraceous. The chelipedes are yel- lowish red, as also the lower surface, and like the ambu- latory legs more or less distinctly spotted.

however, by the epibranchial tooth that is rudimentary, presenting itself only as a small obtuse prominence and furthermore by the different form of the abdo- men. The terminal segment with obtuse tip and very slightly concave lateral margins is a little shorter than its base is broad; the penultimate segment is trapezoi- dal, about as long as the terminal. The anterior margin is very little broader, the posterior, however, almost once and a half as broad as this segment is long, so that the straight lateral margins diverge somewhat backwards.

The meropodites of the ambulatory legs are a little broader and there is no acute tooth at the distal end of their anterior margin. The free border of the front is slightly arcuate, in Pot. silvicola, however, straight. The chelipedes are still equal and feeble, the fingers in contact throughout their length and slightly longer than the palm are distinctly grooved longitudinally, but this is also still the case in the young male from Poetoes Sibau.

I cannot therefore decide whether this specimen belongs to another species or only ought to be regarded as a va- riety of lot. silvicola.

Subgenus Potamon s. s.

Potamon {Potamon) mahakkamense, n. sp. (Plate 8, Fig. 8).

One adult female, without eggs, was captured by Dr. Nieuwenhuis at Bloe-oe, a locality situated ou the Upper Mahakkam, in the source-region of this river, not far from the source-region of the Upper Kapoeas.

This species bears such a striking resemblance to Pot. sinuatifrons H. M. E., three type-specimens of which from the Paris Natural History Museum are lying before me, that I at first hesitated to regard it as different. The three type-specimens, all males and collected by M. Leguillou during the Voyage of la Zélée, are of different size, the largest, however, is still considerably smaller than the female from the Interior of Borneo. Potamon m^ahakkamense now differs from Pot. sinuatifrons by the extraorbital tooth being slightly longer with regard to the distance between the external orbital angles and having a more oblique direction, by the characteristic granulation with which the whole upper surface of the carapace is covered. Though the specimens of Pot. simiatifrons are varnished, this granulation seems, indeed, to want com- pletely. For the rest, as regards the general shape of cephalothorax and legs, this species almost fully agrees with Pot. sinuatifrons.

The carapace is rather much enlarged, the proportion of its breadth to the length (the abdomen excluded) being as 4:3, just as in Pot. sinuatifrons ; it is much broader at the anterior branchial regions than posteriorly and so presents a cordiform aspect. The upper surface is flattened posteriorly, moderately convex anteriorly and declivous towards the orbits and the front. The interregional groo- ves are very faint. The semicircular groove is shallow, in Pot. sinuatifrons it is deeper and the oblique lateral por- tions of the cervical groove are also very shallow. They

reach the postfrontal ridge at the end of the lateral cristi- form portions, about 5 millimeters internally to the epi- brauchial teeth. The mesogastric furrow is narrow, does not pass ou to the front and bifurcates posteriorly into two faintly defined, parallel grooves, that are situated close together and reach only to the middle of the gastric region, so that, just as in Pot. sijiuatifrons, the mesogastric area is not defined anteriorly. This area is rather small and in proportion to the width of the cephalothorax a little less broad than in Fot. sinuatifro?is : in the latter species it measures about one fourth, in Pot. mahakkamense only one fifth the width of the carapace. The rugose urogastric areolets, that are not contiguous, are well- defined, but the depressions bounding the cardiac region are very shallow and iudistinct. The anterior branchial region, twice as large as the posterior, is almost not se- parated from the latter; a shallow groove bounds the posterior branchial region posteriorly, just in front of a raised line, that runs close to and parallel with the lateral parts of the posterior margin and that ends above the legs of the fifth pair. The distance between the external orbital angles measures little more than half the breadth of the carapace. The free border of the front (Fig. 8*), that, like the upper margins of the orbits, is obscurely crenulated, measures scarcely one fourth the width of the cara- pace; it shows in the middle a broad shallow bay, which is about half as broad as the frontal margin, but which, in Pot. sinuatifrons (Fig. 9«) is a little less broad ; the la- teral sinuses are almost indistinct. The outer angles of the front are moderately sharp, the lateral margins are a little oblique, slightly divergent; they make, however, right angles with the contiguous parts of the free border, because the latter are somewhat oblique. The lateral mar- gins of the front curve regularly into the external por- tion of the orbital margin and these external portions run somewhat obliquely forwards.

The interrupted post-frontal ridge resembles that of Pot.

sinuatifrons. The internal portions, bouucling the slightly declivous epigastric lobes, are placed a little in front of and quite separate from the lateral portions; the internal portions are about as broad, taken together, as the free border of the front and are not cristiform, but only rugose and wrinkled. In Pot. sinuatifrons, how- ever, they are more or less cristiform. The lateral portions are cristiform, obscurely crenulate, almost straight; they extend a little beyond the outer angles of the orbits, but stop then abruptly, at a distance of about 5 millimetres internally to the epibranchial teeth, at the end of the cervical groove. Between this spot and the epibran- chial tooth one observes four or five rounded granules. The postfrontal ridge is rather far distant from the free border of the front and from the orbits; the distance be- tween the former and the internal portions measures, in the median line of the carapace, 5 millimetres, so that the front is nearly three times as broad as long. Just as in Pot. siiiuatifrons, the trapezoidal epigastric lobes are bounded posteriorly by shallow furrows, but they are less distinct.

The obscurely denticulate outer margin of the extra- orbital tooth is nearly straight and makes almost a right angle with the contiguous portion of the upper margin of the orbits; this margin has a much more oblique direction than in Pot. sinuatifrons (Fig. 8 and Fig. 9). The extraorbital tooth is slightly concave above and the outer angles of the orbits are moderately sharp ; they reach almost as far forwards as the free border of the front. The epibranchial tooth is also moderately sharp, but small and little prominent; these teeth are placed, just as in Pot. sinuatifrons, a little before the postfrontal ridge, so that a line uniting them passes along the upper margin of the orbits. The epibranchial tooth is comparatively farther distant from the outer angle of the orbits, i. e. the outer margin of the extraorbital tooth is comparatively longer than in Pot. sinuatifrons. The

Motes from the Leyden IMuseum, Vol. XXI.

distance between the epibranchial tooth and the outer angle of the orbits measures justly one sixth, in Pot. sinuatifrons, however, only one ninth of the distance between the outer angles of the orbits, and that distance between the two teeth measures in Fot. smuatifro7is about one third the breadth of the orbits, but in our new spe- cies it is a little more than halfas long as the orbits are broad. The small epibranchial tooth passes into a regularly curved, slightly raised and obscurely granu- late or denticulate crest, that ends about at the level of the posterior boundary of the gastric region, so that the cephalothorax presents its greatest width a little in front of the limit of the anterior third of the upper surface. The postero-lateral margins are straight, rounded and converge as much backwards as in Fot. sinuatifrons; the posterior margin of the cephalothorax finally is slightly concave and measures about one third the breadth of the cephalothorax.

The whole upper surface appears slightly granulate. The upper surface of the front is densely covered with small, little prominent granules, about '/g mm. broad; similar, though somewhat smaller granules are seen between the orbits and the postfrontal ridge. The anterior branchial area is densely beset, just behind the epibranchial tooth, with granules similar to those of the front and these granules pass gradually backwards into short, granulated, oblique rugae that rather den- sely cover the lateral margin of the carapace; they are longest and most distinct near the middle of the lateral margin and become gradually smaller backwards. Near the cervical and branchio-cardiac grooves the granules and short raised lines gradually grow smaller, more flattened and scarcely prominent at all. Flattened, partly confluent and coalescent granules are observed on the epigastric and protogastric areae and these granules become likewise smaller, more flattened and less salient posteriorly and on the car- diac and intestinal regions. To the naked eye, how- Notes from the Ley den ]Museum, Vol. XXJ.

ever, the granulation is visible over the whole upper surface of the carapace.

In the type-specimens of Pot. sinuatifrons^ on the con- trary, the upper surface appears almost everywhere smooth, there are only small granules on the front and on the extra-orbital tooth, while oblique rugae cover the lateral margin of the carapace.

The orbits are transverse, almost twice as broad as high and their width measures two thirds the breadth of the frontal margin ; the lower border that is obscurely crenu- late and more curved than in Fot. sinuatifrons, presents, as in this species, just below the outer angle of the orbits, a small triangular hiatus.

The epistome almost agrees with that of Pot. sinuati- frons. It is smooth, like its anterior and posterior margin ; the process in the middle of the latter is formed chiefly by the median palatal ridge. The lobe at the anterior ex- tremity of the lateral margins of the buccal frame appears regularly curved and distinctly crenulate in Pot. sinuatifrons, but in the new species it is angular and quite smooth (vide Fig. and Fig. 9^).

The subhepatic region is marked in the middle with a transverse row of granules that are partly confluent and so constitute a rather salient, transverse ridge, some other granules are lying around it. The floor of the branchial chamber is densely covered with finely granu- lated, short oblique rugae and is distinctly defined by a groove from the subhepatic region ; the brauchiostegite is rugose externally and a row of small granules is seen along the furrow that separates it from the subhepatic area.

The outer maxillipedes fully agree with those of Pot. sinuatifrons. The furrow on the rather densely punctate ischium-joint runs a little closer to the internal than to the external margin and proceeds from the posterior to the anterior margin of the joint.

The abdomen is densely punctate.

The right chelipede is somewhat larger than the left.

DUTCH BORNEO-EXPEDITION. 97

The meri reach but little beyond the lateral margins of the cephalothorax, the upper edge is unarmed, but trans- versely rugose, the two angles of the lower surface are granular and rather sharp, especially the outer. The lower surface bears a small conical tubercle distally near the inner edge and is somewhat granular around it. The outer surface is also somewhat rugose. The carpopodites are slightly rugose above and armed at the inner angle with a strong spine, that, especially in the smaller cheli- pede, is somewhat flattened and compressed; beneath this spine a much smaller one is seen. The hori- zontal length of the larger hand measures two thirds the width of the carapace, the fingers are about just as long as the palm and the latter is almost just as high at the articulation as long. The outer surface of the palm is co- vered with little salient , transverse rugosities ; on the upper and on the lower margin flattened granules, not at all prominent, are found, but the granules as well as the rugosities are visible to the naked eye. The pointed fin- gers cannot be brought into complete contact, but leave a narrow interspace when closed ; they resemble those of Pot. sinuatifrons, presenting the same longitudinal grooves and rows of puncta ; they are for the rest smooth, the dactylus appears only indistinctly granular at the base. The fingers show several teeth , that are small, obtuse and unequal. The other chela agrees with the described one, but the fingers are distinctly somewhat longer than the palm.

The ambulatory legs are also similar to those of Pot. sinuatifrons. They are of moderate length , so e. g. are those of the antepenultimate pair one third longer than the carapace is broad. The meropodites are rather slender, so are those of that pair almost 4-times as long as broad, and the following joints are also slender, the propodites of this pair being about 3-times as long as broad. The meropodites carry transverse rugosities on their outer sur- face near the upper margin, that is quite unarmed at its

distal end, those of the last pair are a little punctate, smooth. The two following joints are also rugose exter- nally ; the crest on the outer surface of the earpopodites is well-marked except on the legs of the last pair and the propodites present a longitudinal groove in the middle] of their outer surface. The last joints are stout, elongate, a little longer than the propodites, well armed with small spines and slightly arcuate towards their extremities.

The cephalothorax has a light violet colour, the legs are yellowish red.

Amongst the type-specimens that I received from the Zoological Museum of Göttingen is also a female, without eggs, of that species that was referred by Burger (in : Zoolog. Jahrbücher, herausgegeben von J. Spengel, Abth. f. System. V. 8, 1894, p. 2) to Potamon sinuatifrons. It belongs certainly to this species for there are no other differences from the type-specimens from the Paris Natural History Museum than with regard to the dactylopodites of the ambulatory legs. According to the measurements these joints indeed appear comparatively a little longer and so- mewhat narrower than in the Paris types. Burger referred his specimens with some doubt to Pot. sinuatifrons^ for he was misled by the figure of this species in the »Nou- velles Archives du Muséum", that is inexact as shows at first sight a comparison with my figures (Plates 8 and 9, Fig. 9). Potamon sinuatifrons proves consequently to in- habit the Philippine Islands (Zamboanga and Rio Jibon): the habitat was hitherto remained unknown. It is represented in Central Borneo by Pot. maliakkamense and Pot. consohrinum.

(I.e.) under the name of Telph. sinuaiifrons , but they ought to be considered as a new species, though bearing a close resemblance to the former, three type-specimens of which are lying before me (confer p. 92). Fot. consobrinum differs by the still more depressed and flattened cephalo- thorax, by the different shape of the front, by the more enlarged joints of the ambulatory legs and by the shorter dactylopodites. ')

The two specimens, collected at localities rather far dis- tant from one another, though certainly belonging to one and the same species, do not fully agree, so that I prefer to treat of them separately. As the female bears a closer resemblance to Pot. sinuatifrons than the male does, I will describe it in the first place.

With regard to the proportion of the measurements of the carapace, the female fully agrees with the types of Po^ sinuatifrons. The front, however, is very little deflexed, still less than in this species, and it appears a little broader in proportion to its length. The upper margin of the orbits has namely a different direction (Fig. 10* and Fig. 10<^) ; its superciliary portion, forming the lateral margin of the front, makes a very obtuse angle with the adjoining middle portion of the margin and this middle portion runs very slightly backwards before curving towards the external orbital angle. In the types of Fot. sinuatifrons^ however, the lateral margins of the front pass constantly with a regular curve into the middle por- tion of the margin (Fig. 9 and Fig. 9*) and this middle portion runs transverse ly outwards or even slightly forwards; the lateral margins of the front are compara-

1) Milne Edwards (in: Annales Sciences Nat. 1853,. T. XX, p. 211) says that Th. sinuatifrons «ressemble au Tfi. fiuviatilis par sa forme générale". This, however, can hardly be said. When I compare specimens of the European species from the river Sarno near Naples with the types of Pot. sinuatifrons, the carapace of the latter appears more enlarged and more flattened, the extra-orbital tooth has a quite other shape and direction, the antero-lateral margins are more finely denticulate, the front has a difTerent form and is but finely granular and there are still more differences.

tively longer than in the female from the Upper Sibau and in consequence of it the front of the latter appears slightly broader. When the carapace is looked at from above, the median sinus of the frontal margin appears, in Fot. sinuati- frons, a little deeper than the lateral ones (Plate 8, Fig. 9^^) ; in the female from the river Sibau, however, the free bor- der of the front appears almost straight in the middle, but the lateral sinuses are well-defined (Plate 6, Fig. 10«). The postfrontal ridge almost fully agrees with that Pot. sinua- tifronSi the median or internal portions, however, are cris- tiform, in the type-specimens of the other species indistinctly so. The oblique grooves between the gastric and the epi- branchial region are somewhat deeper than in Pot. sinua- tifrons and the cardiac area is bounded posteriorly by a transverse depression from the intestinal one. In both spe- cies are the epigastric lobes distinctly defined posteriorly by a transverse furrow. The raised line above the legs of the 5*15 pair is more prominent than in the other species. As regards the course of the lateral margin of the cepha- lothorax, the form of the extra-orbital tooth and of the epibranchial one, the proportion between the distance of these teeth from one another and that between the external orbital angles, the female from the Upper Sibau agrees with Pot. sinuatifrons. The free border of the front and the supraorbital margin are almost smooth, but in Pot. sinua- tifrons distinctly crenulate.

Though the type-specimens are varnished , the upper surface of the cephalothorax seems, however, to present the same structure in both species. The anterior branchial region is covered with oblique rugosities that, near the postero- lateral margins, gradually pass into less salient, short, raised lines. The extra-orbital tooth is granular above, the front finely granulate. The epigastric lobes and the proto- gastric regions appear very slightly rugose anteriorly, the rest of the surface is minutely punctate.

The inferior orbital margin is distinctly crenulate in Pot. sinuatifrons, but in the female from the upper Sibau scar- Notes from the Leyden JMuseum, Vol. XXI.

cely so. With regard to the rugosities on the subhepatic and subbranchial regions both species nearly resemble one another, they are, however, less prominent. The epistome presents also the same characters, but the lobe at the ante- rior extremity of the lateral margins of the buccal frame, that in Pot. sinuatifrons is crenulate, appears nearly smooth, just as in Fot. mahakkamense. The external maxillipedes fully agree in both species. Sternum and abdomen are smooth, finely punctate.

Though the type-specimens of Pot. sinuatijrons are all males, the anterior legs seem to resemble those of the female from the Upper Sibau. The left is a little larger than the right. The angles of the lower surface of the arms are distinctly granulate in Pot. sinuatifrons, but almost smooth in the female, the rugosities on the upper edge are also less defined. The upper surface of the wrists carries very small , partly inosculating grooves and depressions , but in the males of Pot. sinuatifrons one observes finely granulated raised lines ; just as in this species the inner augle is armed with a short conical spine, beneath which is a very small one. The chela of the left leg is just as long as measures the distance between the outer orbital angles, the fingers, in contact throughout their length, are a little longer than the palm, that is somewhat less high at the articulation of the fingers than it is long. The outer surface of the palm is beset with transverse rugo- sities and inosculating foveae , but in the types of Pot. sinuatifrons transverse granulated lines are seen at least on the upper margin and on the upper half of the outer surface and some granules at the base of the index. The fingers are distinctly grooved and multidentate. The ambu- latory legs resemble those of Pot. sinuatifrons, but the propodites of the 5^^ pair are slightly broader and the dactylopodites a little shorter and stouter.

The male from Mount Damoes differs from the female by the following. The cephalothorax isalittle broader anteriorly, as is proved by the proportion between its length

and the distance between the external orbital angles or that between the epibranchial teeth. The extraorbital tooth is comparatively larger. In the female the distance be- tween the external orbital angle and the tip of the epi- branchial tooth measures just one eighth part of that between the external orbital angles ; in the male from Mount Damoes, however, one sixth, but perhaps may this difference be attributed to the different size of these spe- cimens. In the female the free border of the front mea- sures exactly one third the length of the carapace, just as in the type-specimens of Pot, sinuatifrons ; in the male from Mount Damoes it is, however, considerably broader and such a specimen was described by Miers (1. c). The front, the frontal margin, the orbits and their margins fully resemble, however, those of the female ; the free border of the front (Plate 6, Fig. 10^^ and Plate 9, Fig. 10*) presents three very shallow bays, the middle of which is not deeper than the lateral.

The postfrontal ridge is a little less salient, but for the rest agrees with that of the female. The grooves between the gastric region and the epibranchial are not so deep. The median process of the posterior border of the epi- stome has a different form in the male and in the female (Fig. iOf and Fig. 10^), but this is also the case in the two specimens of Pot. sinuatifrons, in the larger one it is triangular about as in the female from the Upper Sibau, but in the smaller specimen its form agrees very well with that observed in the male from Mount Damoes. This dif- ference therefore cannot be a sexual one. The posterior margin of the epistome is transverse in Pot. sinuatifrons, but both in the male and in the female o? Pot. consobrinum it runs on each side slightly backwards.

The lower surface of the carapace and the outer foot- jaws fully agree in both individuals.

The abdomen (Fig. 10») resembles that of Pot. sinuati- frons. The terminal segment is a little shorter than its base is broad, the lateral margins are slightly convex, the tip

is obtuse. The penultimate segment is a little shorter, its posterior margin is somewhat more, the anterior a little less than once and a half as broad as this segment is long and the lateral margins are nearly straight.

The anterior legs are unfortunately lost. The joints of the ambulatory legs are slightly broader in proportion to their length than in the female from the Upper Sibau, the dactylopodites, however, even those of the 5*b pair, fully agree.

Both specimens have the same colour. The upper sur- face of the cephalothorax and of the ambulatory legs is olive-green, the free border of the front, the orbital and the antero-lateral margins are yellow, the lower surface presents the same colour though lighter; the anterior legs of the female are reddish with a greenish hue and the extremities of the fingers are dark brown.

I suppose that the described differences will prove to be individual or sexual or a consequence of different age, when a large series of specimens from the same localities once will be examined.

Potamon (Potamon) Melanippe, n. sp. (Plate 9, Fig. 11).

Two males and two females were collected on the Liang Koeboeng Mountains, March and April 1894.

The largest specimen is a female without eggs, the other female somewhat younger and the abdomen of which is still triangular, was found in the forest. The larger male has about the same size as the younger female, the other male is quite young. Perhaps, however, even the largest specimen has not yet attained its full size. This remarkable species has the same enormously long and slender ambulatory legs as Pot. austenianum W.-Mas. from Cherra Piinji, Assam, but it appears to be a different species. As was rightly remarked by Wood- Mason (1. c. p. 204), Pot. austenianum differs from all its

known congeners at first sight by the extraordinarily long and slender ambulatory legs and I will therefore firstly indicate the differences between the Indian species and that from Central Borneo.

Pot. mistenianum W.-Mas. was described after a single adult female, the carapace of which is 48 mm. broad; the cephalothorax of the largest specimen from Central Borneo is not yet half as broad, but, as was already re- marked, our specimens are perhaps not yet fully deve- loped. The two females show an epibranchial tooth, obtuse and small, but the males present only a trace of it; the epibranchial teeth of Pot. austenianum, however, are de- scribed as » extremely salient". The epibranchial teeth pass backwards as crests that in the species from Assam are prominent and dentate, in the Borneo specimens, however, only finely denticulate or granulate. The epibranchial teeth are situated comparatively more back- wards, farther distant from the external orbi- tal angles than in the Indian species so that the extra- orbital tooth appears larger and the postfrontal ridge placed more backwards. The post-frontal ridge runs as in Pot. mistenianum', the epigastric lobes that are finely gra- nulate and confluent with the protogastric regions, are somewhat advanced, the mesogastric furrow between them is deep, but not continued untill the cervical groove. The epigastric lobes are somewhat oblique and separated by shallow furrows from the contiguous portions of the post- frontal ridge. These external portions are granular but do not reach until the epibranchial teeth. The mesogastric area is bounded in the Indian species by distinct furrows from the rest of the gastric region; these furrows are wanting completely in Pot. Melanippe. The external portions of the supraorbital margins are more oblique, as may be seen by comparing my figures with those of Wood-Mason, and the orbits are little broader than high, those of Fat. austenianum appear to be only half as high as broad (Wood-Mason, 1. c. fig. 2). The

Notes from the Leyclen Museum , "Vol. XXI.

posterior margin of the cephalothorax is considerably broader: in the species described by Wood-Masou, an adult female, the breadth of the posterior margin is not yet half as large as the distance between the external orbital angles, but in Pot. Melanippe it measures about three fourth parts of the latter. The merus-joint of the outer foot-jaws has a different form, the external margin being convex ; the ischial line is situated a little closer to the internal margin of the ischium.

These are the principal differences, I will add still the following. The front has apparently the same shape in both species. The mesogastric furrow is continued on the front, that is strongly deflexed and its rather coarsely punctate upper surface is raised on each side into a slightly convex eminence and the superciliary portions of the upper orbital margins are also longitudinally convex. As the lateral margins of the front converge rather much towards the anterior margin, the front is much wider at the base than at the free border. The latter is slightly bayed in the middle and convex on each side; it forms obtuse rounded angles with the lateral margins. One observes , parallel with the anterior margin of the front and close to it, a very finely crenulate crest or ridge; this crest appears (Figs. 11« and 11*) also concave in the middle, but does not reach to the lateral margins of the front, the lateral ex- tremities being separated from them by narrow fissures. The outer orbital angles are very salient, acute, and pro- ject a little beyond the anterior border of the front (Fig. 11«) ; the outer margin of the extra-orbital tooth has a S-like form , its upper surface is somewhat concave and granular.

The antero-lateral portions of the branchial region are marked with coarse granulations and the postero-lateral margins show finely granulate, oblique wrinkles. Oblique deep grooves separate the anterior branchial lobe from the protogastric region, but these furrows are not continuous to the semicircular groove, with other words the cervical groove is interrupted. The protogastric regions are also

108 CRUSTACEANS OF THE

finely granular, the granules gradually decrease in size backwards and change into impressed puncta on which microscopical hairs are inserted, so that the metabranchial, cardiac and intestinal areae appear densely punctate. The posterior margin of the carapace is slightly concave.

The finely crenulate lower margin of the orbits shows no hiatus or incision near the external orbital angle, is regu- larly arcuate and the inner angle is obtuse. The posterior margin of the epistorae (Fig. 11^) is smooth and the trian- gular, rather obtuse tooth in the middle is separated by narrow fissures from the lateral parts that run like a S.

The branchial floor is covered with oblique wrinkles, the subhepatic region is also somewhat rugose and parallel rugae are seen on the brancbiostegite near the boundary of the subhepatic area. The merus-joint of the outer foot- jaws (Fig. 11^) is quadrate, its anterior margin is straight or a little concave, the outer margin convex; the ischial line runs near the internal margin of the ischium, some- what obliquely and does not reach the anterior margin.

The male abdomen (Fig. 11^) bears some resemblance to that of Pot. borneense v. Marts, var. hilaris. The terminal joint is once and a half as long as broad at the base, has a rounded extremity and its margins are slightly concave posteriorly. The penultimate joint is a little shorter, quadrate, as long as broad anteriorly and its posterior margin is a little less broad than the anterior. Sternum and abdomen are densely punctate. The abdomen of the largest female resembles that of Fot. stoliczkanum (Wood-Mason, 1. c. pi. XII, fig. 10), but the terminal joint is triangular, its length being in proportion to its breadth at the base like 4 : 7.

Like those of Pot. austenianum, the chelipedes are un- equal, either the right or the left being the larger; they seem to agree in both species. The upper margin of the meri carries transverse or oblique wrinkles and is unarmed at the distal end ; the margins of the lower surface that bears no tubercle near the articulation of the wrist, are a little tuberculate. The wrists are granularly rugose above

and armed with a short, somewhat flattened spine at the inner angle, below which there is no other. The horizon- tal length of the larger chela is equal to the length of the cephalothorax and this hand is slightly more than twice as long as high ; the fingers are a little shorter than the palm and are, both in the male and in the female, in contact throughout their length. The palm is densely covered with fine granules, that are partly arranged in transverse rows. The fingers are very finely granular, they are marked with longitudinal rows of puncta ; the dactylus is not grooved, but a longitudinal groove is observed on the outer surface of the index, that, however, is rather shallow.

The ambulatory legs resemble those oi Pot. aiistenianum, so are e. g. those of the penultimate pair 3-times as long as the carapace and the meropodites of this pair are just as long as the cephalothorax. The meropodites and the propodites of the penultimate pair are 5-times as long as broad and the terminal joints are almost as long as the propodites. The meropodites are unarmed at the distal end of their upper margin, that is transversely wrinkled or somewhat granular ; their outer surface is densely punc- tate, though smooth. The ambulatory legs are glabrous.

The cephalothorax of the three large specimens has a dark bluish-black colour above, below on the sternum and the abdomen it is yellowish; the chelipedes are dark olive green, the fingers have yellow tips and are marked in the middle with one or two narrow yellow stripes. The ambu- latory legs are black with yellow tips. The young indivi- dual is reddish brown coloured.

Potamon {Geothelphusa) kenepai, n. sp. (Plates 10 and 11, Fig. 12).

One single male collected, January 1894, in a forest on Mount Kenepai.

Though this specimen bears a close resemblance to Pot. hendersonianum n. sp., it is to be considered, I think, as a different species.

The cephalothorax is subquadrate, little broader than long, the greatest width being in proportion to the length about as 5 : 4 and the distance between the outer angles of the orbits being but little shorter than the length of the cephalothorax. The branchial region, moreover, is somewhat expanded laterally, so that above the legs of the antepenultimate pair the cephalothorax appears almost just as broad as at it greatest width. The carapace is moderately convex anteriorly, depressed poste- riorly and the interregional furrows are rather deep. The deep cervical groove is interrupted, as in so many other species ; the anterior portions directed towards the epibran- chial teeth, would make a right angle with one another when prolonged backwards. Rather deep depressions sepa- Notes frora tlic Leyden IMuseum, Vol. X!XI.

DUTCH BORNEO-EXPEDITION. Ill

rate the cardiac region from the intestinal one and shal- low depressions are observed between the somewhat convex, anterior branchial lobe and the much smaller posterior. The slightly concave posterior margin of the cephalothorax is just half as broad as the latter.

The post-frontal ridge is only represented by the promi- nent epigastric lobes, that are wrinkled, advanced, con- fluent with the protogastric regions , but subsiding abruptly towards the front; the mesogastric furrow is deep and extends almost to the middle of the gastric region, but the mesogastric area is , however, confluent backwards with the protogastric lobes. The postorbital groove is shallow. The front fully agrees with that Pot. hendersonianum^ but it is slightly narrower and the lateral margins are somewhat less oblique. The upper sur- face of the front is a little more concave in the middle and the postorbital groove is smooth.

The nearly transverse upper margin of the orbits (Fig. 12«) is slightly sinuous and the acute external orbital angles reach not as far forward as the front. At a short distance behind the outer angle of the orbits one observes a rudimentary epibranchial tooth, represented only by a slight notch in the margin and the small prominence passes backward and inward, for a very short distance, as an obscure crest, that is just as long as the distance between the extra-orbital angle and the epibranchial tooth. A little more backward, the cephalo- thorax appears very slightly swollen outside of and beneath the antero-lateral margin and, posterior to the antero-lateral crest, the whole margin of the cephalothorax is marked with oblique raised lines. To the naked eye the upper surface of the cephalothorax appears smooth and shining, but, examined under an ordinary lens , a fine and close punctation is observed on the whole surface; the puncta are of different size, larger puncta being distributed amongst numerous microscopical other ones. Strangely enough the right half of the cardiac region is quite smooth, devoid of Notes from the Leyden IMuseum, "Vol. X^X.1.

112 CRUSTACEANS OF THE

puncta. The margins of tbe front and of the orbits are smooth.

The orbits and the eye-peduncles fully agree with those of Fot. hendersonianum and this is also the ease with the lower surface of the carapace. The median process of the posterior margin of the epistome, however, is not pro- minent and broadly rounded.

The ischial line on the somewhat punctate, outer maxil- lipedes (Fig. \2d) is a little oblique and runs somewhat closer to the internal than to the external margin of the ischium-joint ; it reaches not to the anterior margin. The merus-joint is somewhat broader than long, the slightly arcuate outer margin makes a right though rounded angle with the straight anterior one.

The abdomen resembles that of Pot. hendersonianum, so that I refer to the figure of that species and to the mea- surements. The distance between the extremity of the abdominal cavity and the posterior margin of the buccal frame (Fig. 12^") is distinctly shorter than that be- tween the extremity of the ischial line on the outer foot- jaws and the outer margin of the ischium. Sternum and abdomen are finely punctate.

As well the anterior as the ambulatory legs resemble almost completely those of Pot. hendersonianum, but the fingers of the larger hand (Fig \2<^) show a very fine granulation, when examined under a lens. For the rest I refer to my figure and to the measurements. The upper surface of the cephalothorax has a reddish-brown colour, that is somewhat lighter on the ambulatory legs ; the chelae are yellowish, but the distal half of the fingers is brown.

Potamon (Geofhelphusa) hendersonianuin, n. sp. (Plate 11, Fig. 13).

Two males and four females, one of whicli is ova-bearing, were collected, October 1893, by Dr. Hallier at the top of Mount Damoes, Sambas, at an altitude of 1100 1800 meter.

One very young male, collected by Dr. Nieuwenhuis, 1893, at the foot of Mount Damoes.

This species , that I have the pleasure to dedicate to Prof. ,1. R. Henderson of Madras, belongs to the subgenus Geothelphusa, because the post-frontal ridge is only repre- sented by the more or less distinct, epigastric lobes and it differs from allied species by the epibranchial teeth wanting completely.

The cephalothorax is little enlarged, the greatest width

being iu proportion to the length as 4:3. The gastric region is somewhat convex from before backwards (Fig. 13*) and also from side to side; the anterior branchial lobe is slightly swollen and scarcely distinct from the pos- terior. The cardiac and intestinal regions finally are flat- tened. The cervical groove is interrupted; the two anterior shallow depressions between each protogastric region and the anterior branchial grooves that reach till near the lateral margin of the cephalothorax, would, when prolonged backwards, make an angle with one another slightly larger than a right one, their direction being very oblique ; the median portion of the cervical groove is also shallow. An anterior and a posterior pair of puncta, ad- joining the cervical groove on the gastric region, are quite distinct. The mesogastric furrow is moderately deep, slightly continued on to the front but not backwards, so that the gastric region is not subdivided. The epigastric lobes that are little prominent and confluent backwards with the protogastric regions, are two small areolets covered with oblique wrinkles and directed somewhat obliquely, but sometimes they are scarcely defined ; they are together a little less broad than the front. On each side of the epigastric lobes the anterior boundary of the protogastric regions appears more or less distinctly wrinkled. The flat- tened cardiac region, somewhat broader than long, is boun- ded posteriorly by a shallow transverse depression from the intestinal area that is likewise much broader than long and covered with very fine transverse wrinkles, but the cardiac area is confluent, on each side, with the posterior branchial one. The urogastric lobules are small, rugose and not contiguous to one another.

The front is strongly deflexed downward and raised into two very slightly convex eminences, that are defined laterally from the upper margin of the orbits by a well- marked furrow, which curves laterally towards and issues into the quite shallow post-orbital groove or depression between the orbits and the protogastric regions. The upper

surface of the front, consequently slightly concave in the middle, appears very finely wrinkled and granular, when examined under a lens and by means of the latter a still finer granulation is observed on the post- orbital groove. The free border of the front, which, just like the upper margin of the orbits, is smooth, is divided by a moderately deep and broad median sinus into two distinctly arcuate lobes, that pass with a regular curve into the lateral margins of the front i.e. into the upper margins of the orbits, so that it is somewhat diffi- cult to measure exactly the breadth of the free border. It appears, however, to measure about one third the width of the cephalothorax. The lateral margins of the front diverge moderately backward, so that the front is much broader at its base than at its free border; measured in the middle, the height of the front i. e. the distance be- tween the epigastric lobes and the anterior margin, appears to be one third the breadth of the latter. A distinct trans- verse crest runs immediately behind and contiguous to the free border of the front, though this crest extends not along the whole breadth of the margin (Fig. 13*).

The moderately sharp outer angles of the orbits reach a little less forward than the front; the distance between them is about as large as the cephalothorax is long. The lateral margins of the cephalothorax are S-like arcuate, so that the carapace is narrowest at the level of the posterior boundary of the gastric region and the postero-lateral mar- gins are somewhat concave (Fig. 13). One observes almost along the whole extent of the lateral margins numerous, partly interrupted , oblique raised lines ; they are rather long, reaching nearly to the middle of the branchial regions. The foremost of these lines that bounds anteriorly the oblique anterior portion of the cervical groove, runs obliquely towards the lateral margin of the cephalothorax and other interrupted lines border that groove posteriorly ; between the outer angles of the orbits and these foremost oblique Hues the lateral margin of the cephalothorax is slightly

carinate, but for the rest the margin is rounded. An epi- branchial tooth, even an epi branchial notch, that e. g. is observed in Geothelphusa Kuhli de M., are wanting completely. The gastric, cardiac and bran- chial regions are densely punctate, for the rest smooth ; the puncta are somewhat larger on the protogastric lobes than posteriorly. The slightly concave posterior margin of the cephalothorax is, in the male, about once and a half as broad as the free border of the front, in the female somewhat broader.

The orbits are transverse, their width measures two thirds of the free border of the front and they are once and a half as broad as high (Fig. 13*). The lower margin that is finely crenulate, is slightly arcuate, without a notch near the outer angle and the obtuse- inner angle is not prominent. The eye-peduncles are finely granular.

The oblique raised lines of the lateral margin of the cephalothorax pass forwards on to the inflected portion of the carapace, i.e. to the branchial floor; a smooth inter- space, though no furrow, separates it from the subhepatic region, which is likewise beset with several raised lines, running, however, more transversely. The groove between the subhepatic region and the branchiostegite is deep and the latter is also covered with transverse and oblique, prominent, raised rugosities. The median process of the posterior border of the epistome is prominent, obtuse.

The well-marked ischial line on the slightly punctate outer foot-jaws runs much nearer to the inner than to the outer margin and is not continued to the anterior margin of the ischium-joint; the merus-joint is a little broader than long, the curved outer margin makes an obtuse angle with the shorter, very slightly concave anterior margin (Fig. IB*^).

The sternum of the male is smooth, finely punctate. The distance between the anterior extremity of the abdomi- nal cavity and the posterior oblique margin of the buccal frame (Fig. 13»') is a little broader than the distance

between the anterior extremity of the ischial line on the outer foot-jaws and the external margin of the ischium.

The male abdomen (Fig. 13^^) much resembles that of Geothelphusa Kuhli. The terminal joint, the lateral margins of which ai'e slightly concave posteriorly, is a little longer than its base is broad ; the penultimate segment is just as long or scarcely longer than the terminal and appears al- most just as broad as long. The antepenultimate segment is a little shorter than the penultimate and just half as long as its posterior margin is broad, the lateral margins of this segment are very slightly concave.

The terminal segment of the abdomen of the female is triangular, half as long as its posterior margin is broad, with obtuse extremity.

The eggs (Fig. 13y) are few in number, but large, their diameter measuring about 1,75 millim.

In both males the left chelipede is the larger one. The meri are short, projecting but little beyond the lateral margins of the carapace, the dorsal edge without a tooth at the extremity is transversely rugose and the outer sur- face is covered with finely crenulate trausverse rugosities, the two inferior margins are granular, the lower surface is smooth, without a tubercle near the carpal articulation. The wrist is covered with transverse rugosities and bears at the inner angle a short tooth. The larger chela of the adult male (Fig. 13/") is, measured horizontally, as long as the cephalothorax is broad ; the fingers that leave an interspace between them when closed, are slightly longer than the palm and the latter is about as high as long. The inferior margin of the hand is slightly concave below the articulation of the fingers. The somewhat convex outer surface of the palm is smooth and shining, one observes only, by means of a lens, a few finely crenulate, trans- verse lines near the carpal joint. The fingers are regularly tapering; both are smooth, not grooved but marked witli fine puncta, arranged in longitudinal rows, scarcely visible to the naked eye. The index is straight and bears

several small teeth, that decrease ia size toAvards the tip, and one of which, on the middle of the finger, is the lar- gest; the teeth of the dactylus are less prominent and this finger is strongly curved; the extremities of both fin- gers are pointed.

The smaller chela of the adult male measures only two thirds the length of the other; the fingers that are almost in contact, are just as long as the palm and the latter is a little less high than long. The transverse finely crenulate lines near the carpal joint extend almost to the middle of the palm and the longitudinal rows of puncta are faintly grooved.

In the second male the larger hand measures only two thirds the width of the cephalothorax, the fingers that are just as long as the palm , are in contact with one another and the dactylus is not yet arcuate; they are not grooved, but marked with longitudinal rows of puncta. The fingers of the smaller chela are slightly grooved.

In the female the anterior legs are equal or subequal.

In the ova-bearing specimen the left chela is very slightly larger than the right. The fingers are in contact, feebly toothed and more or less distinctly longitudinally grooved.

The ambulatory legs are of moderate length (Fig. 13). So are e. g. those of the penultimate pair almost twice as long as the cephalothorax is broad ; the meropodites that bear no tooth at the distal end, are 3-times and the pro- podites a little more than twice as long as broad ; the terminal joints finally are a little longer than the propo- dites. The compressed dactylopodites are straight, only slightly arcuate at the horny tips and stout; their edges are armed each with 6 or 7 spinules. The meropodites are marked on their outer surface with transverse rugo- sities, except those of the last pair that are only finely punctate. Six or seven spinules are observed along the posterior margin of the propodites. These legs carry on their margins, especially of the three terminal joints, ex- tremely short, setose hairs.

The specimen from Mount Kenepai, that I described above as a new species, Potamon kenepai^ is closely allied, but seems to belong to a different species. The cephalo- thorax, indeed, is slightly longer in proportion to its breadth, less expanded laterally at the level of the anterior branchial region and less narrowed posteriorly. There exists a rudi- mentary epibranchial tooth. The epigastric lobes are more prominent and the front is a little less broad. The median lobe of the posterior margin of the epistorae is less pro- minent, broadly rounded. The distance, finally, between the anterior extremity of the abdominal cavity of the male and the posterior margin of the buccal frame is distinctly shorter than the distance between the anterior extremity of the ischial line on the outer foot-jaws and the external margin of the ischium. The fingers of the larger chela appear very finely granular under a lens, in Pot. hender- sonianum, however, this minute granulation is scarcely perceptible.

Potamon {Geothelphusa) montanum Burger, from the island of Luzon, a male type-specimen from the Göttingen Mu- seum is lying before me, is a different species. The cepha- lothorax is not enlarged posteriorly, so that the postero- lateral margins are not concave , as is the case in the Borneo-species. The oblique wrinkles on the lateral mar- gins are shorter, less distinct and the oblique, lateral por- tions of the cervical groove are almost completely wanting.

The extra-orbital angle is less prominent. The free- border of the front has a different shape and the posterior margin of the epistome is much deeper notched on each side of the median process. The orbits are higher in proportion to their breadth , and have a different form ; the male abdomen has also another form, sternum and abdomen are much more coarsely punctate. The ambulatory legs finally are more slender than those of Pot. hendersonianum.

Burger is quite wrong when he describes the cephalo- thorax as being not punctate: the punctulations, on the contrary, are quite distinct.

Fotamon (Geotlielphusa) Kuhli de Man, from Java, is still more closely allied. Two adult males and two young females from Tjibodas, described in my paper on the Crus- tacea collected by Prof Max Weber in the Indian Archi- pelago, are lying before me. In the Java-species one observes, a little behind the outer angle of the orbits, a distinct epibranchial notch and the distance be- tween the outer angles of the orbits is a little shorter in proportion to the width of the carapace, so that the latter appears less broad anteriorly than in Pot. hendersonianum. The lateral margins of the front that is more profoundly emarginate, are a little more oblique and the external portions of the supra-orbital margin that runs transversely outward in Pot. hendersonianum are direc- ted somewhat obliquely forward in the Java-spe- cies; in the latter the outer angle of the orbits is much less prominent. In a front view of the cephalothorax the gastric region appears transversely a little more con- vex in the Borneo- than in the Java-species; the front appears in that view higher in Pot. hendersonianum and the two halves of the free border are arcuate in the Borneo species, but almost straight in Kuhli (vide de Man, in: Max Weber, Zoologische Ergebnisse einer Reise nach Niederlandisch Ost-Indien, T. IT, 1892, PI. XV, fig. 3a).

The interspace between the inner angle of the inferior orbital margin and the front is broader in the Java spe- cies than in the other. The merus-joint of the outer foot- jaws has a somewhat different form and in Pot. Kuhli the ischial line reaches to the anterior margin of the ischium. The male abdomen presents not exactly the same form. The dactylus of the larger chela of the male is more strongly arcuate in Pot. hendersonianum ; the ambulatory legs have about the same shape in both species, but the dactylopodites are different. In Pot. Kuhli they are narrower, more slender and bear in this species a smaller number of spines on their posterior margin, so e. g. on the penultimate pair only three, but five in the other species.

Potamon {Geothelphusa) Burgerij n. sp.

(Plates 11 and 12, Fig. 14).

One single male, captured on Mount Liang Koeboeng.

This species that I have the pleasure to name after Prof. 0. Burger of Göttingen , author of a paper on Thelphusidae, has a rather thick eephalothorax, for it is a little thicker than half the greatest width. The eepha- lothorax is almost quadrate, little enlarged, the greatest width, anteriorly, being only one and one fourth times as broad as the eephalothorax is long. The upper surface appears, in a lateral view, strongly convex from be- fore backwards, very slightly also from side to side. The semicircular groove, bounding the gastric region posteriorly,

is shallow, but the oblique lateral portions of the cervical groove are wanting completely. The branchial regions that are undivided, are separated by a shallow transverse groove from the intestinal area, but the cardiac region that is very slightly convex transversely, is confluent both with the adjoining intestinal and branchial regions. The two urogastric areolets are distinct, they are not contiguous and slightly wrinkled. The mesogastric furrow dividing the two little prominent epigastric lobes, is narrow and continued neither on the front nor backwards, so that the gastric region is undivided and, as has already been observed, this region is also confluent with the branchial lobes. The two epigastric lobes are wrinkled above, slightly declivous towards the front, but confluent with the gastric region as well backwards as laterally. The gastric region as well as the branchial one slightly slope downwards towards the orbits, but, except the epibranchial lobes there is no trace of a postfrontal ridge. The scarcely salient outer angles of the orbits, that pro- ject somewhat less forward than the front, are almost as far distant from one another as the cepha- lothorax is long, the distance between them being but very slightly shorter than the length of the cepbalo- thorax. In a front- view of the cephalothorax (Fig. 14^), the orbits show a very slight oblique direction ; they are just as broad as the free border of the front and once and a half as broad as high. They have an oval outline, the finely crenulate lower margin is entire, without a notch near the outer angle and the inner angle is triangular, not at all prominent. The front is very narrow, the free border measuring exactly one third the distance between the extraorbital angles, and the front is about half as high as the free border is broad. When the carapace is looked at from above, the free border appears divided by a median triangular emargination into two ar- cuate lobes (Fig. 14''), but in a front-view (Fig. 14*) the frontal margin appears almost straight. The front is slightly

inflected inward in the middle, and the small inflected portion is bounded above by an angular crest (Fig. 14*). The outer angles of the front are rounded, they are almost right, so that the lateral margins of the front are nearly parallel, very little convergent.

The lateral margins of the cephalothorax are S-like cur- ved (Fig. 14). They at first diverge somewhat outward, ascending upwards, so that the cephalothorax appears broad- est anteriorly, along a line dividing the anterior fourth part from the second. This foremost portion of the lateral margin is surmounted by a finely creuulate raised line or ridge and it appears slightly angular at a distance of one millimeter from the extraorbital angle, but there is no trace of an epibranchial tooth. The lateral margins then curve inward and at last again outwards, so that at their posterior extremity, above the legs of the penulti- mate pair, the cephalothorax presents its greatest width (Fig. 14), being here even a little broader than anteriorly. The postero-lateral margins are rounded and marked with oblique raised lines that are continued on the lower sur- face of the cephalothorax ; these lines are altogether want- ing, however, just above the bases of the ambulatory legs. A few short, oblique, finely crenulate raised lines are also seen on the anterior branchial lobe. The upper surface of the cephalothorax is smooth and shining ; exa- mined under an ordinary lens it appears finely punctate, the puncta are more crowded on the posterior branchial and intestinal regions than elsewhere. The front, that is very slightly concave in the middle, appears somewhat un- even near the lateral margins.

A faint groove separates the branchial floor from the subhepatic region on which one observes a few small ru- gosities, and rather prominent oblique rugae are found on the branchiostegite. The epistome is smooth, the median tooth is narrow, prominent and obtuse (Fig. 14*). The outer foot-jaws (Fig. 14^^) are a little punctate , the puncta on the ischium-joint are somewhat larger than those on the

roerus-joint. The ischial line on the outer foot-jaws runs near the internal margin and is prolonged till near tlie anterior border of this joint; the merus-joint is quadrate, the slightly arcuate outer margin makes an obtuse angle with the much shorter anterior one.

The abdomen (Figs. 14^ and lA'-') resembles that oi Fota- mon horneense^ var, hilaris, being quite narrow and with concave lateral margins. The distance between the anterior extremity of the abdominal cavity and the oblique posterior margins of the buccal frame is a little larger than that between the anterior extremity of the ischial line on the outer foot-jaws and its external margin (Fig. 14^). As regards the shape of the abdomen, I refer to the figure and to the measurements. Sternum and abdomen are smooth with rare punctulations.

The right chelipede (Fig. 14/) is much larger than the left. The arm is short, its upper margin without a tooth at the distal end and with short transverse rugosities on its outer surface ; the lower surface is smooth , without a tubercle near the carpal articulation and with rather sharp margius that are beset with acute granules. The carpus is covered with small rugosities and its inner margin shows a row of small acute tubercles; there is a short, acute, slightly compressed spine at the inner angle. The larg*er chela is stout, almost as long as the cephalothorax is broad and the fingers, in contact throughout their length, are just as long as the palm. The palm is very slightly higher than long, a few very small granules, that are not at all prominent, are scattered on the rounded upper mai-gin of the palm, a few also on the very convex outer surface near the carpal articulation and on the rounded lower margin, but the greater part of the outer surface is quite smooth, even not punctate. The fingers are together less high than the palm, so that the lower margin of the index is not placed in the same horizontal line as the arcuate lower margin of the palm. The outer surface of the some- what compressed immobile finger is very slightly convex,

Notes from the Ley den Museum, Vol. XXI.

DUTCH BORNEO-EXPEDITION. 125

but flattened at the base and covered with small, acute, little pi'ominent granules, that are more crowded on the lower margin than on the outer surface. The dactylus is also covered with similar granules, especially above, and under a lens rows of very fine puncta are moreover observed, but the fingers are not grooved. Both fingers carry some small teeth, two of which on the index are somewhat larger than the others. The inner surface of the hand is almost smooth.

The smaller chela measures only two thirds the width of the cephalothorax, the palm is a little less high than long, and the fingers that are slightly longer than the palm, are distinctly grooved longitudinally, each groove presenting a row of puncta. The fingers are more slender than those of the other hand and more feebly toothed.

The ambulatory legs are long and slender, so are e. g. those of the penultimate pair three times as long as the cephalothorax. The meropodites of this pair, just as long as the latter, are three times as long as broad ; the propodites of this pair, half as long as the cephalo- thorax, are 2'/2-times as long as broad in the middle and the dactylopodites are a little longer than the pro- podites.

The dactylopodites are slender, straight and quite narrow, tapering but very slightly towards the extre- mities, so are e. g. those of the penultimate pair about 9- times as long as broad at the base; they are armed with several small spinules along their edges. The posterior margin of the propodites, that are covered with small depressed granules arranged partly in a longitudinal row, carries also 6 or 7 spinules, the anterior margin of the meropodites is quite unarmed, without a tooth at the distal end and their outer surface is covered with a few small rugosities, except those of the last pair that are smooth. For the rest the ambulatory legs are glabrous.

is lying before me , is a different species. In this form, indeed, there is an epibranchial tooth ; the front is much broader than the orbits and appears more enlarged, with the lateral margins more oblique. The postorbital groove is much deeper and the cephalothorax is much narrower posteriorly than anteriorly, that is not the case in Potainon Burgert. The dactylopodites of the ambulatory legs have about the same form in both species, but they are longi- tudinally ridged above in the Australian species, smooth in Pot. Bilrgeri and the propodites of these legs are some- what more slender in the latter.

The Borneo-collection contains also a female without eggs, unfortunately the locality has not been indicated. This specimen very probably belongs to the same species though it shows a few slight differences (Plate 12, Fig. \^g). In the male, described above, the upper orbital margin runs very slightly backwards, in the female however slightly forwards. The epigastric lobes are ill- defined. The ambulatory legs are a little more slender, as will be seen by comparing the measurements. The chelipedes seem to present only the usual sexual differences. The right chela is somewhat larger than the left; it is less high than that of the male, the granulation extends almost over the whole surface of the palm and the index is very slightly grooved. The smaller chela agrees with that of the male, but the granulation is more distinct. The female has a somewhat larger size than the male.

Potamon {Geothelphusa) bicristatum^ n. sp. (Plate 12, Fig. 15).

Two females , without eggs , were collected by Dr. Biitti- kofer Mount Liang-Koeboeng. Both specimens are almost of the same size , the larger one was captured in a forest.

This species presents some affinities to Pot. {Geothelphusa) Dehaani White and Pot. {Geothelphusa) ohtusipes Stimps., both from Japan ; specimens of the former are lying be- fore me.

The cephalothorax is rather much enlarged, the pro- portion between the width and the length being like 7 : 5 ; it presents its greatest breadth along a line dividing the anterior third of the upper surface from the middle. The upper surface appears slightly convex anteriorly, as well from before backwards as transversely, curving regularly downwards towards the front, but it is flattened poste- riorly. The interregional grooves are a s little developed as in Pot. Dehaani. The cervical groove is distinctly

marked mesially as the usual semicircular groove, but tliere is no trace at all of the lateral portions, the gastric region being confluent with the branchial one. The cardiac region is likewise not defined, the brauchio-cardiac grooves are quite indistinct. The small urogastric areolets that are not contiguous, are only defined by minute puncta, but by no grooves and the depression between the anterior and the posterior branchial region is very faint. The nar- row linear mesogastric furrow is continued on the front and also backwards, almost to the middle of the gastric region but does not bifurcate. The epigastric lobes are faintly marked; they are separated anteriorly by a trans- verse groove from the front and each lobe is bounded posteriorly by a slightly oblique ridge, in front of which one observes a row of fine puncta. These two ridges (Fig. 15") meet together at the mesogastric furrow and they are a little farther distant from the anterior groove than the latter from the free border of the front. In the smaller specimen the two ridges are indistinct, the transverse rows of minute puncta being only developed. On each side of the epigastric lobes one observes a transverse ridge, that runs somewhat obliquely forward and outward ; these two ridges that are characteristic of our species and that are equally distinct in both individuals, so that the specific name is derived from them, are apparently the rudimentary traces of the post-frontal ridge. They reach laterally as far as the eye-peduncles and are nearly straight. The distance between the outer orbital angles that are not at all prominent, measures about two thirds the greatest width of the cephalothorax, the proportion be- tween both being as 5:3. The free border of the front (Figs. 15*^ and 15*) that is straight, not emarginate in the middle, measures one fourth the greatest breadth of the cephalothorax. It makes angles of 135° with the upper margins of the orbits, about as in Pot. Dehaani, so that the shape of the front is nearly the same in both species, the front being distinctly broader above than at the free border.

Notes from the Ley den Museum, Vol. XXI.

DUTCH BORNEO-EXPEDITION. 129

The front is almost vertically deflexed downward, appears very slightly concave in the middle and its height, in the middle, measures one third the breadth of the free bor- der. The front projects a little more forward than the outer angles of the orbits.

The lateral margins of the cephalothorax are regularly arcuate. The antero-lateral margin is raised into an ob- scurely denticulate crest that curves a little inward there where the cephalothorax is broadest. There is even no trace of an epibranchial tooth. The postero-lateral margins that are straight, converge slightly backwards, so that at their posterior extremity , above the base of the legs, the cephalothorax is still almost once and a half as broad as measures the distance between the external orbi- tal angles; the postero-lateral margins are rounded and marked with 8 or 9 short oblique, raised lines. The pos- terior margin of the cephalothorax that is somewhat con- cave in the middle, is just twice as broad as the free border of the front and but little less broad than the distance between the external orbital angles.

The upper surface of the cephalothorax is smooth and shining; examined under a lens one observes everywhere a fine punctation, the puncta are more numerous on the cardiac and posterior branchial regions than anteriorly and are rare on the mesogastric area. Near the antero-lateral margins a few oblique wrinkles are more or less distinct, but a granulation is nowhere observed; on the front and just behind the orbits a few larger puncta are distributed. The free border of the front and the upper margin of the orbits are quite smooth. In a front view of the cephalothorax (Fig. IS'^), the oval orbits appear so me- what oblique; they measure two thirds the breadth of the frontal margin and are about half as high as broad. The regularly arcuate and obscurely crenulate lower margin presents no hiatus near the outer angle and the inner angle is not dentiform, not at all prominent. The eye-peduncles are smooth, punctate.

130 CRUSTACEANS OF THE

The median process of the smooth posterior margin of the epistorae is broadly triangular and terminates into the prominent, compressed, median, palatal ridge, visible in a front- view of the cephalothorax ; the lateral ridges are also distinct. A faint transverse groove separates the subhepatic region from the branchial floor, both these re- .gions as also the branchiostegite are nearly smooth, the oblique wrinkles on the postero-lateral margins of the cephalothorax reaching not far on the floor of the bran- chial chamber. The merus-joint of the outer foot-jaws is a little broader than long (Fig. Ih^^); the arcuate outer margin makes an obtuse angle with the shorter straight anterior one. The ischial line runs, a little obliquely, just in the middle of the ischium-joint , but does not reach the anterior margin. The outer foot-jaws are punc- tate, smooth.

The abdomen of the female is also finely punctate, the terminal segment is triangular with obtuse extre- mity. The chelipedes of the female are small, the right is somewhat larger than the left. The arms are short, the upper margin unarmed at the distal end, the lower surface smooth, with no tubercle near the carpus and with entire margins ; the upper margin carries a few oblique wrinkles. The upper surface of the wrist is slightly wrinkled out- wards and near the inner margin, but almost smooth in the middle ] there is a small acute spine at the inner angle. The right chela is a little more than half as long as the carapace is broad , the fingers, in contact with one ano- ther, are slightly longer than the palm that is just as high as long. The palm bears on its outer surface a few small, more or less sharp tubercles, that are somewhat larger at the base of the immobile finger and that are also observed on the two ridges bounding the longitudinal groove on the outer surface of this finger ; the faintly grooved dactylus is also a little tubercular. The immobile finger is armed with eight or nine acute teeth , about of the same form and size, those of the dactylus are

smaller. The other chela is smaller, but for the rest agrees with the right.

The ambulatory legs are sleuder and moderately long, so are e. g. those of the penultimate pair a little more than twice as long as the cephalothorax. The meropodites of the penultimate pair are 4-times as long as broad, their upper margin is slightly rugose, but devoid of a tooth at the distal end and their outer surface is nearly smooth. The propodites of this pair are about 3-times as long as broad, they show a few small spines along their posterior margin, but they are also smooth. The terminal joints of the penultimate legs are 6-times as long as broad at the base, slightly longer than the propodites and taper rather regularly towards the slightly arcuate tips; some small spinules are observed along their margins. The three ter- minal joints of the ambulatory legs are also smooth and glabrous.

The cephalothorax is lead-coloured, the legs are lighter and yellowish marmorate.

Fotamon Dehaani may at first sight be distinguished by its less enlarged cephalothorax, that is considerably longer in proportion to its breadth. The antero-lateral margin is more coarsely granulate and one of these gra- nules is sometimes more prominent than the others and then appears as a rudimentary epibranchial tooth, but in other specimens there is no trace of such a granule. The lateral ridges, traces of the postfrontal crest, that are observed in Pot. hicristatum, are quite absent in the Japanese species. The oblique rugosities on the postero- lateral margins are indistinct or quite wanting in Pot. Dehaani. The posterior margin of the cephalothorax is much broader in the Borneo-species than in the other and so still other differences might be enumerated.

Potamon ohtusipes Stiraps. from the Japanese island of Ousima is also different, I think. According to measure- ments of this species published some time ago (de Man, in: Max Weber, Zool. Ergebnisse einer Reise uach Nieder-

Il, 1892, p. 290) the cephalothorax of this species appears also somewhat longer in pro- portion to its breadth than that of Pot. hicristatum., the upper surface is somewhat granular near the antero- lateral margin and probably not ornamented with the ridge-like traces of the post-frontal crest that are charac- teristic of the species of Mount Liang-Koeboeng : no doubt still many other differences exist.

I was enabled to compare it with the ova-bearing fe- male from Padang, mentioned in the first of the two papers quoted above. Both specimens closely agree with one an- other and certainly belong to the variety gracilipes, esta- blished by myself in 1891 (Notes from the Leyden Museum, Vol. XIII, p. 49) after a young male from the Pacific Ocean, but the carapace of the female from the isle of Lemoekoetan is somewhat shorter in proportion to the distance between the outer orbital angles. In Dr. Hal- lier's specimen the front is a little less prominent and its anterior margin is straight in the middle, but in the other a median emargination, though quite shallow, is still percep- tible. The ambulatory legs fully agree. The named diffe- rences may, I think, be regarded as individual.

Five specimens, viz. 2 males and 3 females, were collected by Max Moret, probably at Sintang.

Miss Rathbun has recently proposed (in: Proc. Biol. Soc. of Washington, Vol. XI, 1897, pp. 89 and 90) the name of Sesarma for my subgenus Episesarma and that of Holometopus M. E. for my subgenus Sesarma and I think she is in the right.

This new species now belongs to the subgenus Sesarma

Rathb. and bears some resemblance to Sesarma angustifrons A. M. E. The male from Tahiti that was referred by my- self, iu 1889, to the latter species (in: Zool. Jahrbücher, Abth. für System. T. IV, p. 432, PI. X, fig. 10), was, upon my demand, kindly sent me by the Direction of the Senckenbergische Gesellschaft at Frankfort on the Main , so that I now am able to indicate the differences.

The 5 specimens of Ses. Amphinome are, 1 think, still young, none of the females carrying eggs and therefore it is a pity that no more specimens were collected.

As regards the general shape of the cep halothorax, the new species closely resembles Ses. angustifrons, the slightly concave lateral margins diverging also somewhat back- wards, so that the cephalothorax is broadest above the legs of the antepenultimate pair. The cephalothorax is , however, a little shorter in proportion to the distance between the external orbital angles and the straight pos- terior margin is comparatively broader than in Ses. an- gustifrons.

In the male from Tahiti the posterior margin is just half as broad as the distance between the outer angles of the orbits and less broad than the front, but iu Ses. Amphi- nome it is considerably broader and distinctly broader than the front. The upper surface is slightly con- vex from before backwards. The interregional grooves are somewhat deeper and more distinct than in the Sesarma from Tahiti ; in the male of Ses. angustifrons the mesogastric region is undivided , but in Ses. Amphinome it is distinctly tripartite. The protogastric regions are covered with some small tubercles anteriorly, immediately behind the post-frontal lobes and the hepatic area is also somewhat tubercular; in the male from Tahiti these small tubercles are not observed. The upper surface of the cepha- lothorax appears finely punctate under a maguifying glass, but the puncta are irregularly distributed. On the tuber- cular anterior half of the protogastric regions, on the hepa- tic area, on the grooves between the three parts of the

mesogastric lobe and on the intestinal and posterior bran- chial regions the puncta are very fine, numerous and crowded ; on the rest of the surface the puncta are rare and the transverse anterior branchial lobes, that are situa- ted immediately behind the protogastric regions, are almost smooth, devoid of puncta. The strongly declivous lateral sides of the cephalothorax are covered with numerous obli- que raised lines.

The upper margin of the front is a little more than half as broad as the distance between the extra- orbital angles, the proportion of its breadth to the latter is the same as in Ses. angustifrons. The four post-frontal lobes, placed in a straight transverse line, are separated from one another by rather deep grooves just as in Ses. angustifrons ; they are prominent, though they do not conceal the inferior margin of the front, when the cara- pace is looked at from above. The internal lobes (Fig. 16«) are once and a half, in Ses. angustifrons (Fig. 17) al- most twice as broad as the external ; they are rounded and almost smooth. The front (Figs. 16«and 16*) that is a little concave and vertically deflexed downwards, making a right angle with the upper surface of the cephalothorax , is almost 4- times as broad as high in the middle ; it has a somewhat different form in both species. The lateral mar- gins, indeed, that are parallel with one another in Ses. angustifrons, slightly converge in Ses. Amphinome and the inferior margin is a little arcuate. The latter presents a slight, moderately broad emargination in the middle, in Ses. angustifrons (Fig. 1 7) the median sinus is much deeper; in a front- view of the cephalothorax this median emargination is also visible, in the other species not. On each side of the median sinus one observes on the front a transverse ridge, about as broad as the inner post- frontal lobes and contiguous to the lower margin of the front; these ridges that do not reach the lateral angles of that margin, are quite absent in Ses. angustifrons.

In the middle the front appears somewhat granular. lu

one of the female specimens the lateral grooves dividing the postfrontal lobes from one another are wanting, the internal lobes being coalesceut with the external ones, but this is of course an abnormity. The orbits are large as in Ses. angustifrons and the eye-peduncles project a little more beyond them than in the species from Tahiti.

Both species may at first sight be distinguished by the different shape of the extraorbital tooth. In Ses. Amphinome (Fig. 16«) this tooth is less prominent, less acute and comparatively much smaller than in Ses. angustifrons, its outer margin is more curved iuward and the notch separating it from the epibranchial tooth is larger and deeper. In the species from Ta- hiti only a trace of a second epibranchial tooth is ob- served, but in Ses. Amphinome this second tooth is quite distinct though small and little prominent, and separated from the first by a distinct notch ; both epibranchial teeth project laterally less outwards than the extra-orbital tooth and are obtuse. In Ses. angustifrons the extra-orbital tooth is slightly longer than the epibranchial, but in Ses. Am- phinome the first epibranchial tooth appears distinctly somewhat larger and longer than the extra-orbital; the outer margin of the first epibranchial tooth is slightly arcuate and this tooth is somewhat raised upwards. A few short fine hairs are seen on the postfrontal lobes, on the tubercles of the hepatic area and on the lateral margins of the epibranchial teeth.

As regards the lower surface of the cephalothorax, e. g. the form of the epistome and of the outer maxillipedes, the two species closely resemble one another; in both the merus-joint of the latter is little longer than broad, the proportion being as 6 : 5, it is oval and rounded anteriorly.

The abdomen of the male (Fig. 16<") has also about the same form, but the penultimate segment is a little shorter in proportion to its breadth: in the male of Ses. angustifrons the penultimate segment is 2^/3 mm. long, its posterior margin 5^/- mm. broad.

The chelipedes of the male are almost equal ; they nearly agree with those of Ses. angustifrons. lu both species the inner angle of the wrist is obtuse, without a trace of a tooth and the upper surface is granular. In the larger male the horizontal length of the hand (Fig. IG'^') measures two thirds the width of the cephalothorax. The fingers are regularly tapering and have pointed tips, while those of Ses. angustifrons are slightly excavated at the extremities, but this may perhaps depend upon their young age. The fingers are a little longer than the palm. The convex outer surface of the latter is granular as also its upper margin, that presents no trace of pectinated ridges ; the convex inner surface bears a transverse row of granules, between which and the wrist the surface is somewhat granular, in Ses. angustifrons^ however, one observes a prominent transverse crest with granulated edge. The dactylus is somewhat granular at base, for the rest quite smooth and the immobile finger is also smooth; a few very short fine hairs are distributed on palm and fingers. The ambulatory legs almost closely resemble those of Ses. angustifrons, as is also proved by the measurements. The meropodites e. g. of the penultimate pair are 3-times, the propodites almost 4-times as long as broad and the ter- minal joints are just as long as the propodites. The mero- podites are armed with an acute tooth at the end of their upper margin and show transverse rugosities on their outer surface, while those of the last pair are almost smooth. The dactylopodites (Fig. 16^) are slender, slightly curved towards the pointed extremities; along the posterior margin of these joints and of the propodites two rows of mo- vable spines are observed. Along the anterior and the posterior margin of the three terminal joints, short stiff hairs are distributed, black at their proximal and white at their distal half, but for the rest all these joints are smooth, not tomentose; a few similar hairs are also seen on the margins of the meropodites. One observes these hairs like- wise on the ambulatory legs of 5*^5. angustifrons .1 but the

List of all the species of Potamon Sav. (inclusive Para- thelphusa H. M. E.) described up to the present time, May 1899 ').

1) This List was published already last year in: Annali del Museo Civico di Storia Nat. di Genova, Ser. 2, Vol. XIX, 1898, p. 435, of course without the Borneo-species described in this paper.

The african species are printed in italics. The three following, a description of which has never appeared as far as I know, are nomina nuda and are not mentioned in the List. These species are Pot. gracilipes White 1847 from the Philippine Islands and furthermore Fot. granidostim Marts, and Pot. Schwein- furthi Marts., two species quoted by Hilgendorf (^Monatsberichte k. Akad. d. Wiss. Berlin, 1878, p. 802).

As habitat I have only quoted the locality indicated in the first description of the species.

(Plates 13—15).

When writing my introduction to Dr. Jentink's treatise on the Mammals collected during my sojourn in Borneo (N. L. M. XIX (1897), pp. 1—26), I bad no idea that the publication of the present paper, which at that time was nearly ready for the press, would have to undergo such a long delay. But the duties of my new position as Director of the Zoological Garden at Rotterdam absorbed so much of my time that I could not think much about finishing my manuscript. And even now I am, for want of time, unable to do what I originally had proposed myself to do, i. e. to give a critical review of the birds of Borneo, but must content myself with an enumeration of the spe- cies obtained by myself and my companions, especially by my assistant Mr. Max Moret, who, after my return to Europe, made a small collection of birds in the surround- ings of Pontianak near the west coast, and of Dr. A. W. Nieuwenhuis ^), who, from May 1896 to May 1897 and

from November 1898 to March 1899, made collections of birds on the Upper Kapoeas ') and on the River Mahakkam (East-Borneo) and its tributaries.

Moreover I am indebted to Mr. L. Westeneuk, an oflBcer in the Dutch colonial civil service, at that time » Assistent Resident" at Sanggau, for a small collection of birds preserved in spirits, from the junction of the Sekajam with the Kapoeas River and sent to me after my return to Leyden.

In my above-mentioned introduction ^) I have plainly sketched the oro- and hydrographical conditions of the country as well as its climate and vegetation, factors which are of great influence upon the oro is of the explored ter- ritory, so that I hardly need to add any more particulars to it.

At the same place I called attention to the lack of water-birds in my collection, due to my neglecting to spend some time in the coast-region, and the small collection made by Mr. Moret at Pontianak has not added an impor- tant number of species of water-birds.

The bird-collections made by Dr. Nieuwenhuis, also enumerated in the present paper 3), contain among the 815

specimens, representing 165 species, only 26 species which were not stated by myself from the western side of the watershed, and none were obtained which most likely would not occur in the Kapoeas-basin as well.

With such a great number of species, this collection is quite sufficient to state that east from the watershed the ornis does not show any essential difference from that of the Kapoeas-region. It may now, as I already suggested in my introduction to the enumeration of the mammals, be considered as a matter of fact that the homogenity of the ornis of Borneo is extremely great throughout the vast island, especially as far as the lowland up to an altitude of 1000 meter is concerned.

The region of the Upper Kapoeas having previously been entirely unexplored; I expected to obtain a number of new species, especially in the mountain-forests, but although I worked very hard in collecting as many interesting species as possible, paying special attention to the smaller and more unobvious forms, there is not a single really new form among the 269 species collected, and only two species {Harpactes orrhopliaeus and Cyano- derma poliogaster)^ already known from other islands or from the Continent, were obtained which had not been recorded before from Borneo.

These facts are pleading very strongly for the perse- verance and the great success with which the Kina Balu and the mountainous interior of Sarawak have been explo- red by energetic naturalists as Whitehead, Everett and Hose, who added so many new species, especially mountain forms, that we were not able to enrich this great number with a single new species.

The specimens treated of in the present paper, have been collected in the following localities and on the following dates ').

This collection vs'as accompanied by a journal from the hand of Mr. von Berchtold, with a number of interesting field-notes which are made use of in the present paper, with the exception of the vernacular names. These latter, as a rule, have not the value ascribed to by several authors, as they very often are untrustworthy and misleading. It happens not seldom that one and the same name is be- stowed upon several species (manau tana ^ ground-bird on all the species of Pitta and some other terrestrial birds) or that quite different names, even in the same places and by the same people, are in use for one and the same species.

A very large and important bird-collection has been made by Dr. Nieuwenhuis on his second voyage on the Upper Mahakkam from November 20th 1898 to March 1st 1899. This collection arrived in the Leyden Museum a week ago and was enregistered in the present paper after this latter was made ready for the press. The collection contains 658 specimens representing 141 species, ten of which had not been represented in our previous collections.

Dr. Nieuwenhuis having meanwhile undertaken a new expedition in East-Borneo, this time more to the north, we may hope that he will be able to continue his col- lecting work in a territory which is zoologically still quite unknown, and that his new collections will strongly increase our knowledge of the ornis of the island, though

we may not expect many forms not stated already from Central-Borneo.

For conveniances sake I have adopted in the present list, with but a few exceptions, the systematical arrange- ment used by Count Salvadori in his »Catalogo sistematico degli Uccelli di Borneo", published in »Annali del Museo Civico di Storia Naturale di Genova, 1874", which excel- lent work, treating of 392 species, may still be considered the most important publication on this subject ^).

Another review of the birds of Borneo, enumerating 472 species, has been published by Dr. Vorderman under the title: »Liste des Oiseaux de Borneo" in Natuurkundig Tijd- schrift van Nederlandsch Indie, Vol. XLVI, afl. 3 (1887).

A very important review of the birds of Borneo, worked up to date, is A. H. Everett's »List of the Birds of the Bornean Group of Islands" in the Journal of the Straits Branch Royal Asiatict. Society, 1889, pp. 91 212, with map 2). This list treats of not less than 570 species, a good number of which however are restricted to the island of Palawan, an island which cannot readily be understood as belonging to the » Bornean group of Islands". Since the issue of this useful publication, very successful explo- rations have been made by Mr. Charles Hose and also by Mr. Everett in the Baram valley and the mountainous interior of Sarawak. Especially in this latter region the work of these indefatigable explorers was crowned with enormous success, especially with regard to the great num- ber of new species discovered in the dense and inaccessable mountain-forests (Mount Penrisen, Mount Kalulong, Mount Mulu, Mount Dulit and other mountains with an eleva- tion of more than 1000 meter above the level of the sea).

As I already pointed to in my above-mentioned intro- duction, I was able to state some of those special moun-

taiu-forms, such as Calyptomena Hosei, Cyanops monticola, Malacopteron kalulongae, Rhinornyias rujicrissa, Mesolophus {Ruhigula) montis, Hemixus connectens, Staphidia Everetti, Turdinulus exsul and others in the forests of Mount Kenepai and Liang Koeboeng, and we may be quite sure now that this special ornis of this more elevated zone of Borneo is quite the same on all the mountains of the island, and that these special forms are represented by closely allied forms on the mountains of Malacca, Sumatra and Java.

From the above mentioned localities may be seen that this species is found in the plain as well as in the mount- ain forests. Captain Shelley in his above quoted Catalogue allows only subspecific rank to this Bornean representative of C. chrysopogon^ but our bird is so constantly distinct by its smaller size and the bright yellow forehead that it fully merits to be considered a quite distinct species.

The question whether the adult females are similar in color to the adult males or not, has hitherto never satisfac- torily been settled, though the species is very common in the forest-regions of the above mentioned countries.

Goffin (1. c.) considers the adult female to be of the same color as the adult male, but this opinion is solely based upon a specimen collected by Schwaner and mentioned as a female, while there are strong reasons to consider it an adult male.

Salvadori (1. c.) does not share the opinion of Goffin 's, the collections of Doria and Beccari containing not a single specimen in full color (i. e. with golden yellow fore-head) sexed by the collectors as a female.

Shelley (1. c.) on the contrary, says that the adult female does not differ from the adult male, but amongst the numerous specimens enumerated in the Catalogue, there is only a single female (specimen c') mentioned as adult, thus with yellow fore-head, while all the other numerous authentical females are considered to be immature.

The mentioned two » females" in the Leyden- and in British Museum are, in fact, the only specimens in full color which are mentioned to be females, while in littera-

ture the great number of females are all considered to be immature. Besides the registered specimens in the Leyden Museum the one in Goffiu's Catalogue and my own series, I have before me a number of specimens from Sumatra, collected by Vorderman, Klaesi and Hagen, and all the specimens marked as males have the fore-head more or less golden yellow while this is not the case in any of those marked as females.

After thoroughly considering these heavily weighing facts I come to the conclusion that the adult female of this species may constantly be distinguished from the adult males by the following characters : Chin yellowish greeu (not red), shading off into the blue throat, basal part of the moustachial streak blue (not yellow), fore-head green, somewhat shaded with blue (not golden yellow), extreme base of fore-head tinged with yellow, hinder part of the superciliary streak blue (not black), the occipital patch duller red and less extended than in the male, base of lower mandible whitish instead of black, size alike in both sexes. Immature birds may be recognized by the less . overlapping edge of the basal part of the upper mandible. Yonng birds of both sexes are much like the adult females, but have the chin tinged with olive-gray, and the blue on throat, angle of mouth, under the eye and on the hind part of the superciliary streak is more or less absent, while the red occipital patch is more or less wanting.

In the nearly adult male the green chin is intermixed with red feathers and the red patch on the sides of the throat begins to show very early in males and females.

from Nanga Raoen wants the blue crown-patch and the red collar on the hind neck, while the yellow on the front is not so deep as in adult birds and not extending over the sides of the crown ; the blue color on the throat is paler and less extended, and the red patches on the sides ot the throat are smaller. The whole bird is much smaller than the adult and even smaller than the young specimens from Sumatra, and the bill much shorter, the culmen measuring only two cm. instead of 2,5. Having no adult male from Borneo to compare with, I dare not say that the Bornean specimens as a rale have the bill shorter than those from the Malay Peninsula and Sumatra. Hab.

Dr. Finsch, whom I asked to examine the bird in question, writes me that it is really a good species, allied to Prodotiscus regulus Sund. and that Heterococcyx of Salvadori is a valid genus.

This species is mentioned, as quoted above, under the name of Cuculus Sonnerati by Everett aud Shelley. I feel, however, obliged to maintain the generic name Penthoceryx for the two species Sonnerati and pravatus, convinced as I am that these two species cannot be placed in the genus Cuculus proper. This latter is always characterized by more or less pronounced longitudinal shaft-spots on at least some of the tail-feathers, which character is quite peculiar to this genus only, and as it is not found in Cacomantis Sonnerati and C. pravatus, which two species are, moreover, much smaller than the average size of Cuculus, I do not hesitate to place them under the generic name Penthoceryx as proposed by Cabanis and Heine and later on maintained by Salvadori and other ornithologists.

Notes froin the Leyden Museum, ^'ol. XXI.

DUTCH BORNEO-EXPEDITION. 169

The genus Pentlwceryx is closely allied to Cacomantis^ but differs from it in having the barrings on the tail, as far as they are present, always placed transversely, i. e. in a right angle to the shaft, while in all the species of Cacomantis the barrings on the tail-feathers, as far as they are present, are placed obliquely, which character it has in common with the square-tailed genus Surniculus.

As to the identity of the species pravatus with Sonnerafi, I cannot agree with the view of Shelley's, and prefer to keep both species separate. P. Sonnerafi is a much larger bird than F. pravatus, its wing measuring 5 inches, while in the Malayan birds (P. pravatus) the largest specimen at hand measures but 4,3 inches.

A great series, collected at Ptoema Manoeal, Mount Kenepai, Mount Liang Koeboeng, Poelau, Poetoes Sibau, and on the Upper Mahakkam. The color of the iris differs much in the different specimens, but this difference must be considered to be absolutely individual, and not due to either sex or age, as, for instance, out of two adult males both obtained on the same place and at the same date, one has the iris bluish white, while in the other it is blood-red. Amongst the specimens collected in Borneo, there are some with the iris pure white, bluish white, orange-yellow, orange-red, fiery red and blood-red. The bill is pea-green plantain-green" as I called it in my annotations), lower mandible (with the exeption of the green tip) and the lower corner of the base of the upper

Hab, Throughout Borneo, in the plains as well as in the mountain-forests. Count von Berlepsch, in his above quoted paper, was the first who stated the constant diffe- rence of the Bornean specimens from those from Malacca and Sumatra, which hitherto had been united under the specific name of Ramphococcyx erythrognathus. The principal differences consist in the shape of the nostrils, which are oblong in the Bornean specimens while they are circular in the birds from Sumatra and Malacca, and in the length of the red terminal part of the central tail-feathers which is constantly less in Bornean birds than in those from Sumatra and the Malay Peninsula. The length of wing and tail, said by von Berlepsch to be inferior iu Bornean birds, does not differ constantly in the rich material at hand from Borneo and Sumatra.

Count von Berlepsch, iu his above quoted paper, also mentions the reasons why he re-unites the genera Ram- phococcyx^ Rhinococcyx and Urococcyx, and Dryococcyx with Fhoenicophaes, and I fully agree with the view based upon his arguments. I also confirm the difference in the sex of the present species, which holds well in all the numerous specimens which I have collected and sexed myself during my stay in Borneo, although this is not the case with the three specimens from the Upper Mahakkam, which are probably wrongly sexed by von Berchtold.

eyebrow; a young, not yet fullgrown female with white bill and casque, which latter is but faintly developed, and ashy gray eyebrow, and moreover what I should call a nearly adult female (the sex is thoroughly stated) with black bill and casque, and hardly any trace of a gray superciliary stripe, and the naked skin round the eye and at the base of the lower mandible dark flesh-color (N° 1392 from Poelau), and an adult female (N° 78) from the Upper Mahakkam, with black bill, well-developed black casque and very distinct gray superciliary stripe. Iris in adult and young birds of both sexes reddish brown, bill in adult males yellowish white with black basal edge, in the adult female black, in young birds of both sexes white ; feet dark greenish gray.

Salvadori, in his Uccelli di Borneo, followed Blyth and others in separating the black-billed birds as a distinct species, a supposition which is followed by Vorderman in his above quoted contribution to the Ornithology of Sumatra. I cannot agree with this supposition, but yield to the opinion of Schlegel's who, in his Catalogue of the Bucerotes, p. 7, considers the black-billed birds the adult females of Buceros mnlayanus, and the white billed adult birds as the males, while young birds of both sexes should have the bill white. This latter supposition is not in contradiction with the four young birds in the Leydeu Museum, which all have the bill white. Mr. Grant, in his Catalogue of the Bucerotes in the British Museum (Vol. XVII, p. 369) seems not to agree with the opinion of Schlegel's, as he says that the only diiference between male and female is to be found in the color of the superciliary stripe, which should be white in the male and gray in the female. The black bill is considered by him to indicate a transitional stage of immaturity to be found in both sexes, while young birds of both sexes should have white bills. As to the supposi- tion of the black bill being representing a stage of imma- turity, I cannot agree with Mr. Grant, nor can I consider the color of the superciliary stripe as a characteristical of

the sexes in this species. As I have mentioned already, one of my adult white billed males has the superciliary stripe white, while in the other it is gray, and the same is the case with the white-billed specimens of this species in the Leyden Museum, while one of these latter has no superciliary stripe at all. The black-billed specimens in the Leyden Museum have, as a rule, the eyebrow gray, but three specimens, one from the Continent, one from Banka and one from Sumatra (the specimen described by Vorder- man in his above quoted paper) have broad, pure white eyebrows. For this reason I cannot consider the color of the eyebrow a sexual character. Young birds are easily recognized by having the white terminal part of the tail- feathers spotted with black.

Wahreud er im Flussgebiete des Kapoeas haufig vorkommt, habe ich ihn im Gebiete des Mahakkam nur einmal, und zwar Mitte September 1896 am Bruny-Flusse angetrofFen. Am Koetei-Flusse, unterlialb den Fallen des Mahakkam, habe ich einige Exemplare zu Gesicht bekommen. Doch hier war ihr Betragen ein gauz anderes! Mitte Mai 1897, als ich in der Morgendammerung in einem Boote durch die überschwemmten UferwJilder des Koetei-Flusses hinfuhr, bemerkte ich in den höchsten Baumkronen ein Maunchen, einen starken, pfeifenden und klagenden , Ton ausstossend. Auf diesen Lockruf flog das Weibchen herbei, schien das Mannchen zu necken und flog dann wieder davon. Das Maunchen verfolgte es, setzte sich auf einen andern gros- sen Baum und schrie von Neuem, bis sich das Weibchen abermals naherte. Bei diesem Jagen, das ich einige Tage hinter einander, aber nur am frühen Morgen bemerkt habe, entfernten sich die beiden Exemplare bis auf einige hundert Schritte in den Wald hinein. Nach diesem eigen- thümlichen Benehmen schliesse ich, dass sich die Vogel in der Paarungszeit befanden".

A great number of adult, immature and young speci- mens of both sexes from Pontianak, Poetoes Sibau, Nanga Raoen, the Siniai Valley, and Poelau.

Two fledged young birds have breast and abdomen barred with rosy-red and grayish brown, but in the male the throat is blackish, while in the female this part is yellowish white, which color is separated from the barred breast by a dusky blackish broad bar across the chest. The red color on the rump and the white shoulder-coverts are plainly developed, but the black color of the upper surface yields to a brownish tinge and is destitute of any gloss. The white on the inner edge of the outer tail-feathers varies very much in extent and in some specimens is even entirely wanting. This difference seems to me quite individual, and not due to locality, age or sex of the bird (see also my explanations in N. L. M. 1887, p. 43).

Thirteen specimens of both sexes, from the fledged young to the fully adult bird, obtained on Mount Kenepai, at an altitude of 600 meter, and in the thick primeval forest on the western slope of Mount Liang Koeboeng (800 meter).

As there is not yet published a full description of this species, and Dr. Sharpe having compared it, in his short diagnosis, with S. cyanea (Hume) ') from Tenasserim, which is very rare in collections, I venture to give here a more detailed description.

Adult male. Upper surface deep indigo-blue, more lively on crown and upper wing-coverts, a broad frontal band extending above the eye cobalt-blue, lores and a narrow base of the frontal band black, wing black, all the quills, with the exception of the two outermost primaries, edged with the color of the back ; central tail-feathers like the back, the outer pairs black on the inner and blue only on

the outer web; sides of head and neck, chin, throat, chest and sides of breast blue like the upper surface, centre of breast and flanks more purplish gray, intermixed with white; abdomen, vent and under tail-coverts pure white, as well as a long tuft of fluffy feathers on the sides of the rump; tail and wing unterneath black, the quills faintly edged on their inner webs with smoky brown, under wing- coverts dark gray, the outer parts slightly tinged with blue, edge of wing entirely blue. Iris dark brown, bill black, feet bluish gray, soles orange-yellow. Wing 8 8,4 cm., tail 5,5, tarsus 2, culmen 1,8.

Adult female. Upper surface and anterior part of lower surface russet brown, strongly tinged with ferru- ginous on forehead, superciliary region, lores, sides of head, chin and throat; wing-coverts like the back, quills dark brown, the inner primaries and still more so the second- aries broadly edged with chestnut-brown, upper tail- coverts likewise chestnut-brown, tail dark brown, the cen- tral pair above rufous brown, the lateral pairs edged with rufous brown on the outer web and with white on the inner, the white margin being very narrow if not entirely absent on the outermost pair and rather broad on the three following pairs, but not reaching entirely to the tip. Moreover the third, fourth and fifth pair are margined with leaden blue on the basal two thirds of the outer web, while on the fourth pair this blue color borders a white longitudinal spot. Centre of throat pure white, partly con- cealed by the tips of the posterior feathers being tipped with rufous brown ; breast, flanks and thighs olive-brown ; centre of breast, abdomen, vent and under tail-coverts white, more or less spotted and streaked with the color of breast and flanks ; under wing-coverts white, varied with fulvous, inner web of the quills margined with ashy white. Color of iris, bill and feet as in the male. The female is very much like male and female of Rhinomyias gularis Sharpe in its general coloration and the white gular patch, but is easily distinguished from the latter by

the white pattern on the tail-feathers and the absence of the isabellina superciliary stripe. Wing 8 era., tail 5,3 5,5; tarsus 2, culmen 1,8.

Two fledged young birds (cf and 9)> killed April 2'^ and 5^^, probably just after having left their nest, are dark brown, back and wing- coverts with a large rusty brown subterrainal spot on each feather; the quills broadly margined with the same rusty brown, which color predomi- nates also on the whole head, where it forms broad shaft- streaks, as well as on fore-neck and chest. The centre of throat is already showing the white half-concealed spot of the adult female, the abdomen and under tail-coverts are white, but strongly suffused with dark brown. In both, male ') and female, the white pattern on the tail-feathers is indicated, though they hardly exceed a centimetre iu length.

The adult stage in male and female seems to be attained by a slow change of color rather than by a moult, beginning at the base and slowly proceeding towards the tip of the feather.

The plumage of the adult is first acquired on back, upper wing-coverts and breast, and the last remnants of the rufous spots are found, as is shown by some specimens before me, at the base of the bill and on the superciliary region.

This species belongs to the larger forms of the genus, and especially the bill is rather clumsy. Like its nearest ally, S. concreta from Tenasserim, it is only found in mountain-forests.

This is undoubtedly an error, the bird in question, which still makes part of the Leyden collections, being a female in transitional stage of plumage of S. lanyumas (Horsf.) = Muscicapa cantatrix Temm. The pure white lores combined with the red color of the entire lower surface leave no doubt as to its identity with the female of 5. hanyumas.

Notes from the Leyden JMuseuin, Vol. XXI.

196 UIRDS OF THE

This species is exclusively an inhabitant of the lower country. In the Kapoeas- region we never met with it at any considerable elevation above the plain or the bottom of the valleys, nor is any instance known in literature of its occurrance on the hitherto explored mountains of Borneo, except a female stated by Dr. Sharpe (Ibis 1889, p. 205) to be found by Mr. Whitehead »on Kina Balu at 3000 feet".

I have, however, very strong reasons to doubt the identity of the mentioned female from Kina Balu with 5. elegans. Nay, from the synonymy of S. elegans in the Catalogue of Birds we learn that Dr. Sharpe considers the female of this species to have a white loral spot, as the learned author adds to this synonymy Muscicapa cantatrix Temm. PI. Col. Ill, pi. 226, fig. 2 (9) and Cyornis banyumas Tweedd., P. Z. S. 1878, p. 615 (9), both having white lores. The first is, however, as is proved by the original specimen still preserved in our Museum, nothing but an immature female of S. banyumas, and the second has afterwards been identified by Mr. Everett (Ibis 1895, p. 25) as the female of S. Lemprieri Sharpe. The female in question, from Kina Balu, 3000 feet, very probably belongs to S. coeruleata (Bp.), which is, at least for the basin of the Kapoeas, unquestionably a mountain form, of which I collected females in different stages of plumage, all with more or less distinct rufous or whitish lores.

The real females of S. elegans (two of them were killed together with their males) have no loral spot at all and can only be distinguished from the males by the want of the blue color on chin and throat, which parts are of a somewhat paler rufous than the chest. They can by no means be distinguished from S. turcosa, which is, in fact, nothing but the female of our S. elegans, a conclusion which gets still more strength by the fact that 5. turcosa is likewise an inhabitant of lower countries and was never found above an elevation of 1000 feet.

Six adult males and a nestling of the same sex, and five females in more or less fully developed dress, all obtained in the mountain-forests of the Liang Koeboeng- range, not below 800 meter. Iris dark brown, bill black, feet in fresh specimens purplish, in dry state pale brown, but by far not so whitish as in our typical specimen.

This species is allied to S. banyumas, having the lower surface entirely orange rufous, the centre of the abdomen only being white in some specimens, but it difiers from the latter in having the black chin-spot very small and the moustaches dark blue instead of blackish. Much more important than between the males the difference is between the adult females. In S. hanyumas the adult female much resembles the male in color, but is provided with a conspicuous white loral spot and instead of the large black chin-spot and ditto beard-stripes these parts are rufous like the rest of the under surface. The adult female of S. coeruleata agrees with that of S. hanyumas as to the want of a dark chin-spot, but the upper surface is not entirely blue like in the male, but olive-brown, with a darker, more grayish

1) Dr Sharpe includes Java in ihe geographical distribution of this species, probably on account of a female in the collection of the British Museum, but for the above developed reasons I guess that the specimen in question is an immature female of S. lanyumas.

2) The female of S elegans mentioned at the quoted place will very likely prove to belong to the present species (see my remarks on this subject antea "ander the head of S. elegans).

tinge on the crown, and the blue color is reduced to the upper tail-coverts and the outer webs of the tail-feathers; moreover the lores (and in some specimens also a ring round the eyes) are rufous instead of pure white. In younger females the blue color on upper tail-coverts and tail are entirely wanting. The young male does not pass through the color of the female as is clearly shown by our above mentioned nestling, which, though spotted with rufous all over the upper surface, has the very short quills and upper wing-coverts already edged with the blue color of the adult bird. The entire lower surface of this nestling is orange rufous with a narrow black margin to some of the feathers, but no trace of a black chin-spot can be seen. The feet in the dried skin of this nestling are whitish yellow, like in the type of the species in our Museum, which is, by the way, not a fully adult bird, as it has some rusty red spots to the tips of the greater wing- coverts.

I may not neglect here to say that my series of males from the Liang Koeboeng does not absolutely agree with the type, this latter showing a slightly more purplish tinge on the upper surface, and a more distinct cobalt color on the rump, while the numerous black feathers on the chin indicate a larger black chin-spot than in any of my spe- cimens from the Liang Koeboeng-range. The type being, however, not fully adult (having a few rusty tips to the wing-coverts) and in worn plumage, I dare not keep them separate on account of the above mentioned difie- reuces. Unfortunately I cannot dispose of any specimen of the so-called S. rufifrons from other localities of Borneo and therefore I am unable to tell whether this latter form agrees more with the typical specimen of our S. coeruleata or with my specimens from Liang Koeboeng.

males collected in the above mentioned localities there is not a single one in fully mature dress, all having wings and tail chestnut and breast and abdomen white with a tinge of fulvous. There are, however, specimens amongst them with some blue feathers in the wings and on the lower back and abdomen, and I should say, from this fact, that the fully blue dress of the adult male is only assu- med in the dry season, which, in the Kapoeas basin, be- gins about May. On the other hand I am obliged to state that a specimen obtained on January 29^^ has just as much blue in the wing as others which were shot in April, and a male obtained on May lOt^i has no blue on the wings at all. It is rather incomprehensible that amongst the many males their would only immature specimens be obtained. Strange enough Mr. Oates (Faun. Brit. Ind. Birds, II, p. 43) does not mention the entirely blue dress of the adult male at all.

Twelve specimens from the forests of Mount Kenepai, Nanga Raoen and the western slope of the Liang Koe- boeng, also two specimens from the Upper Mahakkam. A young female (N°. 1123), shot together with an adult male on April 25tli, in the forest of the Liang Koeboeng, probably not many days after having left the nest, is quite different from the adult birds in color. The whole plumage, with the exception of wings and tail, is chest- nut-brown, yieldiug to maroon on the upper surface, espe- cially on the head, but much lighter than the throat in the adult male. Wings and tail, which have not yet attained their full size, are of the same color as in the adult birds, but the scapularies and all the upper wing-coverts are brown like the back. The change of color seems to be

undergone by a complete moult, as amongst the wing- coverts and scapulary feathers there are numerous young feathers making their appearance which are entirely blue (see also Oates, Fauna Brit. Ind. Birds, II, p. 43). Iris blood-red, in the young specimen dark brown, bill black, feet dark gray. The breeding season seems, according to the above mentioned young bird, to be in Marcb and April. Hab. From Tenasserim through the Malay Peninsula to Sumatra and Borneo, on which latter island it is widely dis- tributed and an inhabitant of lower as well as mountainous countries. The Leyden Museum is in possession of speci- mens from Java and Timor. On the Natuna Islands this species seems to be represented by a somewhat different form, Philentoma dubium Hartert.

H. Everett.

The immature male is still wearing the plumage of the young bird, which does not differ from that of the female, but here and there on the brown head and back can be seen some beginnings of the glossy black plumage of the adult male. The rump in the male and both females is

pure white with a few black cross-bars on the anterior part; the shorter upper tail-coverts are also white, while the longer are black like the three innermost pairs of tail- feathers. The three outer pairs of tail-feathers are black with white tip, which latter is largest on the outermost pair, where it has an extent of 3 cm, on the outer, and of about 2 cm. on the inner web. The basal third of the outer web is black. In one of the two females even the fourth pair are, though narrowly, tipped with white.

In a treatise on Sumatran birds (N. L. M. 1887, p. 52) I uttered some doubts as to the distinctness of H. picatus, H. capitalis aud H. iyitermedius, and Dr. Sharpe (Ibis 1889, p. 190) believes that H, picatus and H. capitalis are iden- tical. But in the same year, Mr. Oates (Faun. Brit. India Birds, I, p. 471) points out a constant distinguishing cha- racter, saying that the adult male of H. picatus has head and back glossy black, while in H. capitalis only the head and hind neck are black, strongly contrasting with the back, which is brown. As females and young birds of both species are alike, the difference is entirely based upon the color of the back in adult males. Hemipus capitalis is enumerated by Mr. Ch. Hose (Ibis 1893, p. 395) in his paper on the birds of Mount Dulit. But this is very pro- bably a mistake, as the same bird is mentioned in a pre- vious list (Ibis 1892, p. 434) as H. picatus. It is, on the contrary, very probable that H. capitalis does not exist in Borneo at all aud that the only highland-form occurring on that island as well as in Sumatra belongs to H. picatus.

In my above mentioned paper on Sumatran birds I sug- gested that B. intermeclius Salvad. might be identical with H. picatus. Count Salvadori (Uccelli di Sumatra, p. 209) says that H. intermedins agrees with //. picatus in the shining black color of the upper parts, while in the extent of the white tips to the tail-feathers it resembles H. capi- talis from Nepal. But since there is, in fact, no difference in the extent of the white color on the tail between the mentioned species, this cannot be used as a distinguishing

character for H. intermedius^ which agrees in every respect with the adult males of //. picatus from Burma, Sumatra aud Borneo, contained in the Leydeu Museum. Only the size of the type of H. intermedius (6,5 cm.) is rather sur- passing the average size of H. picatus^ but a male of the latter species from Burma, recently received in exchange from the British Museum, is quite as large, so that the size cannot form a distinguishing characteristical.

This species is a mountain form, representing the lowland- form A. siparaja in the higher regions of Mounts Kenepai and Liang Koeboeng. The female of the present species, for the first time described by Sharpe (see above), is easily distinguished from that of A. siparaja by the orange-red outer edgings to the quills and tail-feathers, and by the shorter tail, measuring only 2,5 cm. instead of 3,3.

Four adult males and a female from Pontianak, Smitau and Roema Manoeal, and an adult male from the Upper Mahakkam. Iris red, bill black, feet olive-brown, soles yellow. This species is easily distinguished from A. malac- censis by the red instead of olive tinge of the sides of the head, the great extent of the red color on the wing-coverts, the absence of purplish blue on upper back and mantle, and by the green instead of yellow color of the lower surface. In the above-mentioned localities it is generally found together with A. malaccensis. Captain Shelley, who in his above-mentioned monograph was the first to separate it from A. malaccensis, mentions as habitat of the present species Malacca and Sumatra, but the Leyden Museum is in possession of a great number of specimens from Borneo, which island is for the first time mentioned as the habitat of this species by Dr. Sharpe (1. c).

Arachnothera modesta Sharpe, Ibis 1889, p. 425. Arachnoraphis Everetti Sharpe, Ibis 1893, p. 561; Whitehead, Ibis 1894, p. 316.

An adult female from the Liang Koeboeng range and an adult male from the Upper Mahakkam, collected by Dr. Nieu- wenhuis in January 1899. Iris brown, bill black, lower mandible horny, feet flesh -color.

Hab. Mountain regions of Borneo: Kina Balu (White- head), Mount Penrisen (A. H. Everett) and the two above- mentioned localities.

This species stands between A. modesta and the Java- nese A. afjinis. With the first it agrees in the olive-green (not golden green) tinge on the upper surface, and with the latter in showing the dark shaft-streaks more distinctly and extending also over the abdomen, and in being larger than A. modesta. The single specimen obtained on the Liang Koeboeng agrees fairly well with a specimen from the Kina Balu in the Leyden Museum but is somewhat less strongly striped and somewhat smaller. It must be observed, however, that the size is not very constant in either of these species, and that the stronger shaft- streaks do not hold well in all the specimens of the present species, so that the validity of this species seems somewhat doubtful. According to Mr. Whitehead (1. c.) the specimens from the Kina Balu, enumerated by Sharpe in

Ibis 1889, p. 425, under the name of A. modesta, belong to the present species, which, on account of the ridged culmen, is a true Arachnothera. I may be allowed to remember, that the Sumatran specimens in the Leyden Museum, from the Highlands of Padang (Dr, Klaesi) and Deli (Dr. Hagen), belong to A. modesta and not to A. af finis, which latter species seems to be restricted to Java.

This opinion is based upon a specimen in the Leyden Museum, labelled «Forsten, Celebes", but no other evidence being known as to its occurrence on that island, the proveniance of the specimen in question must be considered as very doubtful.

Adult male and female from Mount Liang Koeboeng, where the species is found in the undergrowth of the high forest; also from Long Bloe. Iris dark brown or gray, bill black, feet pale blue, soles ochre. The above-men- tioned two birds are similar in every respect to four spe- cimens of R. cyaniventris from Sumatra and one from Ma- lacca in the Leyden Museum, so that I am absolutely unable to find distinguishing characters. Those mentioned by Sharpe in his above-quoted Catalogue do not hold at all in the specimens which I have before me. The larger size of the Bornean specimens is mentioned by Sharpe as the strongest argument for a specifical separation, but the following measurements will show that this argument does not hold with the specimens in the Leyden Museum.

Micropus melanoleucus Sharpe, Cat. B. Br. Mus. VI, p. 69; id. Ibis 1889, p. 274; Everett, L. B. Born. p. 112.

An adult female from the southern foot of Mount Ke- nepai and an adult male from Nanga Raoen, both shot in brushwood, and two specimens from the Upper Ma- hakkam. Iris, bill and feet black. The adult female has the lower surface less dark brown than the male. An imma- ture specimen in the Leyden Museum, from Sumatra, has the upper surface earthy brown, the feathers being broadly edged with olive-brown, while the lower surface is olive- gray. The white patch on the wing is only indicated by a few white feathers.

Hab. Malay Peninsula, Sumatra (Muller, Horner) and Borneo, where it seems to be spread over the whole island. One of the specimens in the Leyden Museum was collected at Koetei on the east-coast and presented by Dr. Vorderman.

species with H. striolatus (Bp.), the types of which are in the Leyden Museum. Both Ramsay and Salvadori stated that their specimens from Western Sumatra differ from the Malaccan and Boruean birds in the following essential points: Upper surface olive-brown instead of olive-green, and the white-striped throat, chest and upper breast olive-green like in H. virescens instead of ashy olive. I regret to say that, after having looked over our material again and com- pared it with my Bornean specimens, I am unable to alter my former opinion (N. L. M. 1887, p. 63) as to the spe- cimens from Sumatra in the Leyden Museum. Our types of Trichophorus striolatus as well as the specimens collected by Dr. Klaesi in the Highlands of Padang have throat, chest and upper breast ashy gray with an olive tinge, while, according to Ramsay and Salvadori, they ought to be olive-green. As to the color of the upper surface, I must say that in our stuffed typical specimens it yields somewhat to olive-brown, but this very slight difference is probably due to their having been exposed to the light for more than fifty years in our galleries. Dr. Klaesi's birds are olive-green above like those I have obtained in Borneo.

Strange enough Nicholson, who described the birds col- lected in Sumatra by Mr. H. O.Forbes (Ibis 1883, p. 246), says that the Sumatran birds have throat and breast streaked with white as in H. malaccensis, but that the edgings of the feathers are olive-brown instead of greenish, and that the head is brown, characters which neither agree with those given by Ramsay and Salvadori, nor with H. malaccensis which has a green head and ashy gray edgings to the breast-feathers.

The birds described by Ramsay and Salvadori are col- lected on Mount Singalang at a height of about 1600 m., and near the Lake Toba about 1500 m. above the sea. Having never seen one of those green-breasted specimens from Sumatra, I cannot tell much about their identity with B. malaccensis^ but all our Sumatran specimens in the Leyden Museum, with the inclusion of the types of Tri-

Hab. From Tenasserim throughout the Malay Peninsula, Malacca, Sumatra and Borneo.

Wardlaw Ramsay (Ann. Mag. Nat. Hist. 1882, p. 431) described 11 Suraatran birds, collected by Karl Bock, as belonging to a new species, which he called C. sumatra- nus, and which would represent C. gutturalis in Sumatra. The material in the Leyden Museum evidently shows that C. sumatranus is a valid species, distinguished from C. gut- turalis by an olive-brown instead of reddish brown crown and a somewhat longer occipital crest, by more richly developed and pure white feathers on chin and throat, and by having the under tail-coverts darker reddish ochraceous. To C. sumatranus belong also the specimens collected by Dr. Klaesi in the Highlands of Padang and wrongly (see also Salvadori, Ucc. di Sumatra, in Ann. Mus. Gen. 1892, p. 61) mentioned by me as C. gtitturalis in N. L. M. 1887, p. 64, though their under tail-coverts do not diöer in color from those in our series of C. gutturalis from Borneo.

On the other hand I learn from the specimens in the Leyden Museum, that C. sumatranus does not represent C. gutturalis, but is found together with this latter species in Sumatra. Besides the typical specimens from

Borneo our collections contain two specimens of the true C. gutturalis from Sumatra, both collected by S. Muller.

As to C, sumatramis, our Museum is in possession of an adult male, collected by S. Muller in Sumatra and strange enough, of another, also of an early date, said to come from Borneo. This latter fact is the more strange, as from Borneo was already known a second species of Criniger, C. ruficrissus, which would take a similar position in Borneo as C. sumatranus in Sumatra. It must be left to later investigations to make out whether C. sumatranus is really an inhabitant of Borneo as indicated by that single specimen in the Leyden Museum.

Finsch (1. c), in describing his C. gutturalis after the specimens in the Leyden Museum, used as objects the male of C. sumatramis and a female of C. gutturalis, as we learn from his remarks about the female.

Six specimens from Mount Liang Koeboeng, where they are found in high forest. Iris blood red, bill horny blue, feet flesh-color.

This species is closely allied to C. gutturalis, from which it differs more strikingly than C. sumatranus especially in the following points: like in C. sumatranus the crown is olive-brown instead of rusty brown, the occipital crest more developed, the white feathers on chin and throat longer and purer white and the under tail-coverts darker brown. Moreover C. ruficrissus is somewhat larger and of a duller color above and below than both its above-mentioned congeners, being less lively olive-green but rather grayish

1) The specimen (N° 653), ranged by Salvadori with some doubts to C. gutturalis, though it is larger and darker above and below, undoubtedly belongs to the present species.

olive, the tail-feathers as well as the upper and lower tail- coverts are much browner than in the other two species. Hab. Restricted to Borneo, where it is not so generally distributed as C. (jutturalis, but rather an inhabitant of the hilly regions than of the plains and coast regions. It is a rather strange fact that two so closely allied species as C. gutturalis and C. rujicrissus were both found together at the same time in the forests of the Liang Koeboeng.

A great number of specimens collected at the foot and on the slopes of Mount Kenepai, on the western slope of the Liang Koeboeng, at Nanga Raoen and in the Sibau valley; also from Long Bloe on the Upper Mahakkam. It is an inhabitant of low and high forest. Iris brown, bill horny gray, feet yellow.

Males and females do not differ in size and color. Birds in transitional stage of plumage have the secondaries strongly margined with rufous. A nearly fledged nestling, obtained on Mount Liaug Koeboeng, differs remarkably in having the upper surface, especially the secondaries and wing- coverts, russet brown instead of olive-green, the crown olive-brown instead of ashy gray, the throat yellow instead of pure white, the chest olive-green instead of ashy gray, and the rest of the lower surface pale sulphur-yellow. Al- though the plumage is quite downy, the long nuchal hairs are already strongly developed.

Hab. Restricted to Borneo, where it seems to be distri- buted over the whole island.

Two specimens (adult male and female) were shot near my station on the western slope of the Liang Koeboeng, at an altitude of 750 m., and an adult male on the Bruny River (Upper Mahakkam). Iris dark brown, bill horny brown, naked skin on the neck blue, feet dark grayish blue.

It is by no means easy to see these birds, as they are running along the ground in high forest hidden by undergrowth and protected by their brown color which

is much that of the dead leaves amongst which they are scratching in search for insects and their larvae. As soon as such a bird finds itself observed, it will rest motion- less on the same spot until it believes the danger to be over. This species is known from Malacca, Sumatra and Borneo. From this latter island it was unknown until a few years ago, when it was found by Mr. Everett on M* Penrisen, and by Mr. Hose on M* Dulit, Mt Kalulong and MtMulu.

An immature male and an adult female with a nestling, all from Nanga Raoen, and ten specimens from the Bruny River (Upper Mahakkam). The younger bird differs from the adult in having the crown strongly tinged with rusty brown, a shade of which color is also to be seen on the abdomen and especially on the thighs; the white beard- spot is fully developed, while the white edging of the black gular spot is but faintly indicated. In the adult bird the white edging is formed by the lateral and hindmost black feathers of the throat having a rather broad and pure white subterminal band. The young bird seems to have no black on the throat, the extent of black in our immature bird being less than in the adult, and some of the lateral feathers being gray with a tendency of getting black, and showing a small central spot of white. Iris in the adult bird red, in the immature one brown, bill in the adult bird black, lower mandible pale blue, while the latter is yellow in the younger bird, feet grayish blue.

The nestling has the entire head, neck and lower sur- face uniform sooty brown ; back, wing and upper tail-coverts chestnut. The white spot at the angle of the bill is fully developed, as also the white spot behind the eye.

neau series there is some difference in the shade of the rufous-brown on the lower surface, some specimens being darker, other paler brown, but this difference appears to be quite individual, having nothing to deal with either sex, season or locality. Especially the darker specimens agree extremely well with the types from Sumatra. Iris brick-red, in some specimens pale yellow, bill black, angle of mouth yellow in a young specimen, feet pale green, soles yellow. Lives in brushwood and the undergrowth of high forest.

Six specimens and a nestling collected on Mount Kenepai, six on Mount Liang Koeboeng, one near Poelau on the Sibau River and three specimens on the Upper Mahakkam. Iris dark brown, bill black, lower mandible horny blue, feet flesh-color. The specimen from Poelau has the quills and tail-feathers broadly edged with rufous, which pecu- liarity is due to its immaturity.

In my above cited note I have already pointed to the difierence in color, probably due to the different localities, of this species. Having no sufficient material, especially from the Malay Peninsula and Sumatra, at my disposal, I cannot tell about the specific value of these differences, but I may be allowed to observe that our two Sumatran specimens have their upper surface browner than all our Bornean birds. Strange enough, there is no difference in coloration amongst my 13 specimens from different loca- lities, though both sexes are represented. Ail, except the above mentioned immature bird from Poelau, have the upper surface, with inclusion of the crown, olive, becoming more brown on rump and upper tail-coverts, while the tail-feathers are earthy brown and edged with rufous brown towards the base. From these the Sumatran specimens in the Leyden Museum differ in having the whole upper sur- face more ruddy brown and the tail-feathers entirely rufous. If all our Bornean specimens would be alike those men- tioned above, they could be easily distinguished ; there are,

however, two specimens from southern Borneo, belonging to the types of Myiotkera poliogenys Mull. MS., and two specimens from Trusan (A. Everett) with the tail rufous like in our Sumatran specimens; they have, moreover, the crown strongly tinged with rufous, which is not the case with my specimens from the Kapoeas-region.

Our specimens, both from South and Central Borneo, are, moreover, much more richly tinged with orange rufous on the lower surface than those from Trusan and from Sumatra. The nestling agrees tolerably well with the adult bird in color, but has the back and quills reddish brown.

Hab. Malay Peninsula, Sumatra and Borneo.

In my above-quoted revision of the genus Turdinus and allied genera, I have already called the attention upon the curious fact that the male (N° 1280) has the tarsi abnor- mally short (18 mm. instead of 25), although this abnormity cannot be ascribed to rhachitis or any other obvious dis- ease. This striking fact is plainly shown in the adjoined figures which my friend Dr. Finsch was kind enough to

draw for this purpose. The bird in question is in every other respect a true T. rostratum, though the shortness of the tarsi does not agree at all with the character of the genus, which latter is chiefly based upon the tarsus being half the length of the tail.

N. B. On his last journey on the Upper Mahakkam (No- vember 1898 to March 1899), Dr. Nieuwenhuis obtained seven males and eight females, some of which were imma- ture or still in down, but even the latter had the tarsus of normal length, i. e. 24 27 mm. A young bird, partly in down, has the upper surface, wing and the still very short tail of the same color as the adult bird, but the downy lower surface is dirty gray with a rufous tinge, and the base of the feathers white.

An adult male and a female, both collected in March at an altitude of 800 m., in the high forest region on the western slope of the Liang Koeboeng Mountain. Iris blood-red, bill black, feet flesh-color. The female looks much like an immature bird, on account of the fulvous markings on front and the sides of head and neck, but in looking over the specimens in the Leyden Museum, I find that the four fulvous- throated birds, which all are marked females, show the same characteristics, so that this might be the really adult stage of the female of this spe- cies. On the other hand I have to state the fact that one of our gray-throated adult birds, collected by Schwaner, is marked » female" on the label.

This species, which frequents the undergrowth of the high forest and is often seen hopping along the ground, is found in Malacca (Wallace a. o.), in Sumatra (a spec- imen from Padang in Mus, Lugd., collected by S. Muller) and in Borneo. On this latter island it has been recorded from the North and from Sarawak, while the Leyden Mu- seum contains specimens from Pontianak (Diard) and from the Barito Kiver (Schwaner and S. Muller).

An adult male from Mount Kenepai and another from Mount Liang Koeboeng. Obtained in the undergrowth of the mountain-forest. Iris gray, bill gray, lower mandible whitish, feet grayish blue.

Hab. The mountain-regions of Sarawak and Central Borneo. Dr. Sharpe recently separated this species from M. magnirostre on ground of its dark crown and the want of dusky streaks on the throat. I may not neglect to say, however, that only in the specimen from Mount Kenepai the throat is entirely unstriped, while in that from Mount Liang Koeboeng the longitudinal dusky streaks on the throat, so characteristical in M. magnirostre, are rather distinct, so that our species differs in fact from M. magni- rostre only by the blackish crown. At the first glance one might be inclined to consider the specimen from Mount Liang Koeboeng as a valid different species on account of its striped throat, but the same peculiarity being found in the most closely allied M. arfine, I consider it more reason- able to unite both birds under one and the same species. In fact there are amongst the great number of sooty brown- crowned M. af/ine, which I collected in Borneo, many specimens with the throat plain white, while in others the throat is more or less distinctly striped with gray. These stripes cannot be ascribed either to the sex of the

Salvadori (I.e.) mentions Alcippe pyrrJio- ptera, but I feel sure that a re-examination of his specimens from Borneo, if really obtained on that island, will prove that they belong to A. cinerea.

A number of specimens obtained at Smitau, Mounts Ke- nepai and Liang Koeboeng between December 8^^ and April 27tli, in low jungle. Also 12 specimens obtained by Dr. Nieuwenhuis on the Upper Mahakkam (Oct. 24'li to Dec. 23id 1898).

There is no difiereuce to be observed in the obtained specimens with regard to the date at which they were shot, but two of them, both shot at Smitau, probably younger birds, are greener above and tinged with yellow on the superciliary streak and on the throat and breast, while in one of them the greater wing- coverts are moreover tipped with white.

An adult male, from Pontianak, an adult male and female, both similar in color, obtained in May at Nanga Raoen, an immature male with red tail but the red on the head not yet fully developed from Smitau (Dec. 9^^) and a young male from Poelau, Sibau R. (April 15^^). Four specimens from the Upper Mahakkam. The specimen from Poelau has, in strong contrast to the adult birds, the upper sur- face olive-green and the white lower surface, and especially the sides of head and neck, very strongly washed with yellow. A few red feathers are making their appearance on the olive-green crown, while on the tail the red color is more strongly developed. The iris in the adult birds is brick- red, the upper mandible brown, the lower whitish, feet pale flesh-color; in the young bird the iris is gray, the lower mandible yellow.

This species is found round the native settlements, very often together with the following species. In the jungle and high forest it was never observed.

Hab. The Indo-Malayan region, Java excepted, and the Philippines. In Borneo it seems to be a rather common bird over the whole island.

This species has a rather wide distribution, as it is re- corded from Malacca, Sumatra and Billiton, and seems to be spread over the whole island of Borneo. From Java it is not mentioned in literature, but the Leyden Museum con- tains three specimens bearing »Java" on their labels. It is a rather curious fact that a specimen was killed as high up as my station on the slope of the Liang Koeboeng, the nearest human habitations being far ofi from this place at the bottom of the valley.

Two adult males and a female, all collected at Nanga Raoen, where we found it in low forest, and three speci- mens from Poetoes Sibau, the Upper- and the Lower Ma- hakkam, collected by Dr. Nieuwenhuis. The specimen from the Lower Mahakkam is immature, showing some remnants of the brown-spotted dress of the young bird, especially on neck and upper wing-coverts. Iris cofiee-brown, bill glossy black, feet purplish white.

The male 1254 and the female 1255 (matched) were shot near their nest (N° 1248^) on May 15*^ in an old, deserted plantation. The nest was placed in a hollow tree ten feet above the ground, and consists of a coating of dead leaves lined with rootlets, small feathers and the abdominal scales of a snake. It contained two eggs of a bluish green color, very thickly speckled all over with reddish brown. Size of the eggs 2,3 -|- 1,8 cm. As both eggs were already fairly set, it is very probable that two is the regular number of the clutch in this species.

This exclusively Bornean species is known from the south- eastern, southern, western, north-western and central parts of the island. In the North it is represented by the white- crowned C. Stricklandi Motley & Dillwyn.

pendem Schwanze, lasst er seinen scliönen, kraftigen Ge- saug, ausgenommeu in der Mittagszeit, den ganzen Tag mit grosseren und kleineren Zwischeuraumen im dichten Busch ertöneu. Dieser Gesang besteht aufangs aus leisen piependen, dann trilleruden raannigfaltigen, schliesslich starken und schwachen, souderbar abwechseluden, steigen- deu und fallenden Tonen, Derselbe wird aber noch schoner und angenehmer, iudem er zuweilen durch die Nachahmung des Gesanges anderer Vogel vermannigfacht wird. Er ist unstreitig der beste Sanger von Borneo und erinnert dem Gesange nach an unsern europiiischen Rohrsanger. Durch nachgeahmten Schlag wird man oft den Vogel augenblick- lich herbeilocken. Mit aufgebauschtem Gefieder und scheinbar kampfbereit erscheint der gestorte Sanger, um wahrschein- lich seinen Nebenbuhler aus dem Reviere zu vertreiben. Doch kaum hat er den Beobachter bemerkt, so ist der Vogel schon wieder verschwunden. Er sitzt dann irgendwo in der Nahe, still doch gut geborgen, und erwartet das neue Gepfeife, Dann aber beginut er zu trillern und zu schlagen mit solch mannigfaltigen Variationen, dass es ein wahrer Genuss wird, diesem Gesange zuzuhören. Der Vogel wechselt den Standplatz jeden Augenblick, verlasst aber den Beobachter nicht, sobald dieser zeitweise irgend etwas vorpfeift. Ich hatte die Freude, einen dieser Vogel das Mili- tarsignal »Vorwarts" in circa 40 Minuten gelehrt zu haben. Des andereu Tages hörte ich in derselben Gegeud den Vogel die neu erlernte Melodie, doch mit einigeu schonen Varia- tionen, pfeifen. Ich ahmte den Lockruf »fi, fi, fi", nach und pfiö darauf das Militarsignal, worauf der Vogel sofort erschien und der Unterricht von Neuem begaun.

Die Kayan-Dajaks in Mendalam (oberer Kapuas) zollen diesem Vogel eine ganz besondere Verehruug. Sie betrachten ihn als den Ueberbringer der Botschaften guter Geister.

A fine series of adult and young birds of both sexes was collected at Pontianak, Smitau (Kapoeas R.), Nanga Raoen (Mandai R.), Poelau (Sibau R.) and on the Upper Mahakkam. Iris dark brown, bill and feet black.

This is the ooly species of Copsychus I met with in Borneo. Along the Kapoeas and its tributaries it is a com- mon bird in and round the native campougs, and we found it also very often in old ladangs (plantations) far off from any human habitation, and, when the water was getting low, on the exposed mud- aud sandbanks along the rivers, searching for worms and insects. It is a very lively bird and an excellent singer. Its breeding time is about April, but as I was collecting that time in the Liang Koeboeng Mountains, where it is not found, I had no chance to pro- cure its nest and eggs.

This species is spread over the whole Indo-Malayan re- gion, being known from Siam and Malacca, Sumatra, Banka, Billiton, West-Java and Borneo. On this latter island it seems to be less generally distributed than its black-bellied congener C. amoenus, as it was hitherto only recorded from Sarawak (Salvadori, Everett). As to the distribution of the present species on the island of Java, a series of 26 spe- cimens contained in the collection of Mr. Vorderman shows

A matched pair of this species (N*^» 986 and 1091), be- longing to the nest and eggs described below, were obtained near my station »Poenan-Grot", on the western slope of the Liang Koeboeng Mountain, on April \A^^ and 23'^ (the female caught on the nest) and a second female, also adult, in the same locality.

As Dr. Sharpe already pointed out (Ibis 1887, p. 444), the first description of this species, by Mr. Slater, is made after an immature bird with the white drops on the lower surface, which reminds much the corresponding parts in our European Nutcracker. Dr. Sharpe considers the present species to be nearly allied with M. Blighi from Ceylon, but

it is wanting the blue shade of the latter on back and breast. As the learned author does not mention any further details about the plumage of the adult birds, it may be useful to give here a plain description.

Adult male: General color sooty black, somewhat darker on the fore-parts above and below; these darker parts are, especially when viewed under a certain light, more or less strongly glossed with purplish blue, the hind margin of each feather being of that color; lesser wing-coverts glossy purplish blue, rest of the wing throughout sooty brown, outer under wing-coverts white at their larger basal half, thus forming a small white area which is preceded by some purple-shaded feathers. Feathers on back, rump, flanks, breast and abdomen pure white over nearly their basal half, this color decreasing in extent on mantle and chest, where it is reduced to mere white shaft-streaks, while it is entirely wanting on head, neck, throat, upper- and under tail-coverts and on the thighs. Iris dark brown, bill and feet black. Wing 14,4 cm.; tail 8,2; tarsus 4,5; cul- men 3,3.

Adult female: Similar to the adult male, but some- what lighter and showing, over nearly the whole plumage, a hue of olive- brown when seen under a certain light; the purplish gloss is less obvious than in the male, the pur- plish blue shoulder-spot, however, hardly less strongly de- veloped. It is also somewhat smaller tlian the male. The second female seems to be somewhat younger, being lighter brown and larger, its wings depassing in length those of the adult female.

A young male, to judge from its spotted plumage, is still browner and differs, moreover, from the adult birds in having drop-like white shaft-streaks on the sides of head and neck, on throat, chest, breast and abdomen and even on the under tail-coverts, the drop-like shape of these streaks being strongly visible on chest and breast, reminding our European Nutcracker. The under wing-coverts and the edge of the wing are almost entirely white. This specimen,

collected by Schwaner in South Borneo and registered as a young male of M. cyaneus (Horsf.) is a little larger than the adult male.

This species was found near my above-mentioned sta- tion (784 m. above the level of the sea), at the foot of the high rocks which bear the top-plateau of the moun- tain and over which are dashing down a great number of waterfalls. Along the small rivulets fed by the water- falls and running through the high forest which covers the slope of the mountain, the birds were found running up and down the rocky banks or frequenting the thick underwood, uttering some soft, melodious notes and scratch- ing the ground and turning over dead leaves and other decaying matter in search for insects and small molluscs. In a narrow hole of the perpendicular rock near the sta- tion, about five feet from the ground, we found a nest of this species, and having shot the male, we a few days afterwards took the female, which had not stopped breeding, with nest and eggs during night-time. The nest forms a rather thick and solid construction of moss, and the cup is neatly lined with black rootlets and a few dead leaves, no mud being used in the whole nest. The length of the rather deep cup is 10, the width 8 cm., while the diameter of the whole nest is about 17. Directly behind this nest and even connected with it we found two empty and pro- bably old ones of the same size and construction. The hole being rather narrow and deep, I only succeeded in getting the two foremost, which are now, together with the eggs, in the Leyden Museum.

The two eggs I had in vain waited for more before capturing the female are rather long, slender and conical, their color is white with numerous minute pale reddish puuctulations, which are rather more concentrated round the thicker pole. Louger axis 4 cm., shorter 2,2.

From the fact that the two eggs already contained fairly developed young birds, and that during a weeks waiting no new eggs were laid, considering further that Charles

Hose found a nest of this species with two young birds only, we may fairly conclude that this is the full number of the eggs of a clutch.

Another (empty) nest belonging to this species, and of the same construction, I found very near the top-platform of the mountain, at an elevation of 1100 m., on a pro- jecting boulder of a hugh rock, being protected from the rain by an overhanging part of the rock just above it.

From all we know from the few collectors who hitherto chanced to meet with this species, it must be considered a highland form, living along small mountain-streams in rocky territory. Mr. Whitehead is the first to tell us about its nesting in crevices of rocks (Ibis 1889, p. 269), while Mr. Hose found his above-mentioned nest placed on a tree-stump.

This species is, up to this date, known from North and North-west Borneo and the Liang Koeboeng. The above mentioned young bird from Southern Borneo in the Leyden Museum is hardly collected at Banjermasiu as is mentioned on the label, but is most likely collected in the mountain- region during Schwaner's journey across the island from the mentioned place to Pontianak in West Borneo.

A small number of this species obtained on Mount Ke- nepai 1^550 m.) in January, and on the Liang Koeboeng (800 m.), March and April 2*1. This very nice little bird is found in high forest as well as in low jungle, very quickly running along the ground in search for insects, especially white ants and their larvae.

This species breeds in Eastern Siberia and passes the winter months in more southern districts of the continent and in Borneo. On this island it is recorded from Labuan (Low), Kina Balu (Whitehead) and Baram District (Hose).

230. Ilenicurus horneensis.

Henicurus borneensis Sharpe, Ibis 1889, p. 277; Everett, L. B. Born, p 100.

A small number of this species were collected on the western slope of the Liang Koeboeng, near my station »Poenan-grot",at an altitude of 700 800 meter, and another at a less considerable height on the Liang Gagaug (800 m.) south of Nanga Raoen. Iris dark brown, bill black, feet (claws included) rosy white.

This Bornean representative oi the genus Henicurus stands between the very closely allied H. Leschenaulti (Vieill.) from Java and H. sinensis Gould from China. From the first it differs by the shorter and posteriorly rounded white crown- patch, and from the latter by the narrower tail-feathers which are broadly tipped with white like in H. Leschenaultij while in H. sinensis they show a rather narrow, oblique terminal bar. Curiously enough the reddish wash on upper and under tail-coverts, recorded by Dr. Sharpe in his diagnosis of the Bornean species, is entirely wanting in all my above-mentioned specimens, these parts being pure white.

A young female (nearly full-grown) has the top of the head uniformly colored with the back ; chin and upper throat are white with a slight fulvous tinge, while chest and breast are sooty brown with white shaft-streaks.

As to the habits of this bird I have nothing to add to what is told by Mr. Charles Hose (Ibis 1889, p. 277).

the Malay Peninsula to Sumatra, Banka, Borneo and the Philippines.

I feel obliged, after a close comparison of all the ma- terials in the Leyden Museum, to unite T. nasica Schleg. with T. nipalensis Hodgs. "When describing T. nasica, Schlegel was not acquainted with T. nipalensis Hodgs., and in his Catalogue of Columbae, p. 55, he declares that T. nasica seems to differ from T. nipalensis only by its smaller size, but comparing the sizes of both species as stated by Sal- vadori in the Catalogue of Birds mentioned above, I cannot find any noteworthy difference. Salvadori, in his Catalogue says that the Malayan birds are smaller and duller than those from Nepal and Tenasserim, but these differences do not hold well in the numerous specimens before me.

Eight specimens from Poiitianak, Roema Manoeal, Nanga Raoen, Poelau and three from the Upper Mahakkam. Iris white, outer ring purplish rosy, bill yellowish green, feet red. Among the specimens from the Upper Mahakkam there is a fine adult male (December 19tli 1890) in gray plumage, an aberration in color which is very uncommon among Trerons. It may be described as follows : crown, sides of head and the whole neck entirely gray ; forehead, chin and centre of throat more whitish ; back and shoulders entirely olive-yellow ; rump, upper tail-coverts, wings and tail gray, tinged with olive-yellow; under wing-coverts gray, lower surface of the body normally colored, but the orange- brown of the chest paler, thighs and under tail-coverts gray, faintly washed with pale rufous.

Four males and four females from Mount Liang Koeboeng and from the Bruuy River (Upper Mahakkam). Iris red, bare skin on face and the wattles sky-blue, hind edging of the erect ear-wattles in the fully adult male black, con- sisting of a very short, brush-like covering of scale-like hairs, bill horny brown, lower mandible horny blue, feet coral-red.

This bird is, like the previous species, very shy and living very retired in the thickest mountain-forest. Two of the above mentioned females were caught in snares by my Dyak huntsmen, and the same is said in Mr. von Berch- told's annotations about the specimens obtained on the upper Mahakkam. It is of interest that, while the occi- pital feathers in an adult male are steel-blue and rather short, they are, iu another adult male with still more de- veloped spurs and strongly developed testes (probably in the breeding-season) lengthened to a kind of crest, and reddish brown with black tips. This crested specimen has the wattles very strongly developed and, as mentioned above, the hind edge of the ear-wattles covered with a kind of brush-like hairs. As a rule, I suppose, the wattles will show the greatest development in the breeding season, the male with strongly developed testes and full plumage, obtained in December, has the wattles very long and broad, while in others showing signs of moulting and caught in October, have the wattles less fully developed. Besides the long ear- and baird-wattles, the adult males show a third pair of wattles, though very small, halfway between eye and nostril. All our fully adult specimens have chin and throat thinly covered with short black feathers. In adult males the spur is less strongly developed than in the genus Lo- phura, and not longer than 12 mm., while in the female the spur is only represented by a conspicuous knob. As to the

number of tail-feathers, which is said by Sharpe to be thirty-two in the male and twenty-eight in the female, I can say that it is thirty in males and females. The outer- most as well as the innermost tail-feathers are shorter than the neighbouring one, while the seventh or eighth pair are the longest. The longer upper tail-coverts in the adult male are pure white and rather long and nearly halfway covering the tail-feathers. The wings are strongly rounded, and the primaries are surpassing the secondaries by not more than 10 20 cm, in the male, while in the female they are nearly covered by the secondaries.
