La Guyane prise dans son ensemble, peut être regardée comme un pays tres auciennement colouisé par les nations européennes, aussi ne doit-on pas s'étonner qae sa faune et sa flore aient donné lieu a des travaux, qui ont fait époque dans la science. Toutefois en ce qui concerne richthyologie , bien que ces regions soient arrosées par des cours d'eau importants , c'est a une époque récente que l'esprit s'est porté sur l'étude de cette partie de sa population zoologique. Sans doute depuis longues années des espèces particu- lières de Poissons avaient été sigualées de ces contrées et les traites généraux en ont fait connaitre bon nombre. Mais pour trouver un travail spécial et réellement scien- tifique sur ce point, il faut arriver aux recherches de Richard Schomburgk, lequel en 1841 fit paraitre en deux petits volumes bien connus, l'ichthyologie de la Guyane anglaise. Ce travail fut repris par Muller et Troschel d'après ces mémes collections accrues et complétées , lorsque , quelques années plus tard (1848), on publia in-extenso Ie voyage de ce célèbre explorateur. On doit également citer les ouvrages de M. Kappler qui, ayant pendant de longues années reside a la Guyane, Notes from the Leyden ]Vliiseum, Vol. XX. 1 2 ICHTHYOLOGIE dans la partie hollandaise , a publié en 1854 et 1881 ^) sur ce pays des travaux plutót relatifs sans doute aux questions politiques et économiques qu'aux études seientifiques et particulièrement zoologiques , mais oü se trouve cependant une liste nominative d'animaux vertébrés envoyés par lui au Cabinet d'Histoire naturelle de Stuttgart. Il y énumère 98 espèces de Poissons , l'absence de détails ne permet pas de savoir exactement dans quelles conditions ils ont été recueillis, il semble que M. Kappler les donne comme pris dans Ie Surinam , c'est a dire comme d'eaux douce , quoique une vingtaine d'espèces au moins puissent être bieu plutót regardées comme marines et doivent avoir été capturées au voisinage de l'embouchure du fleuve. Cependant les poissons nettement dul9aquicoles sont encore nombreux dans cette liste, notamment les Siluridse et les Characinidse, families dans chacune desquelles il n'est pas compté moins de 27 espèces. Dans l'intervalle , sans parier de travaux sur les Poissons de TAmérique intertropicale oü quelques espèces ont pu être signalées, on ne trouve guère a citer que deux notes de Bleeker, l'une sur les Silures de Surinam conserves aux Musées de Leyde et d' Amsterdam (1864), l'autre sur un Stolephorus (EngrauUs) de la même localité (1866). La collection que Ie Musée de Leyde a bien voulu confier a mou examen ofïre eet intérêt que la rivière Berbice, oü elle a été recueillie par Ie Dr. C. G. Young, ne parait pas avoir donné lieu jusqu'ici a des recherches de ce genre. Situé entre Ie Coreutyne a l'Est, l'Essequibo a rOuest , ce cours d'eau semble moins considerable que ceux-ci , sou parcours est estimé a 186 kilometres, tandis 1) Kappler, 1854.

Notes from the Leyden Museum , "Vol, XX. DE LA GUYANE. Ó que Ie premier aurait environ 400 kilometres , Ie second , de beaucoup Ie plus considerable, 965 kilometres. On ne peut toutefois considérer cette collection comme donnant une idee complete de la faune , Ie nombre des sujets est évidemment trop restreint; d'autre part Ie point oü elle a été faite , New Amsterdam , se trouve situé vers Tembouchure de la rivière Berbice et il y a par suite mélange d'espèces dul9aquicoles et marines, cependant elle renferme, comme OU pourra en juger, quelques specimens tres curieux. Voici l'énumération des espèces recueillies : Fam. Gymnotidse. 1. Sternopycfus carapo (Linné). 2. Carapus fasciatus (Pallas). Fam. Siluridse. 3. Pimelodiis holomelas Günther. 4. Callichthys callichthys (Linné). 5. » littoralis Hancock. 6. Plecostomus plecostomus (Linné). 7. Loricaria maculata Bloch. 8. » filamentosa Steindachner. 9.

Batrachidse. 16. Batrachus surinamensis Bloch-Schneider. Fara. Scisenidae. 17. Ancylodon ancylodon (Bloch-Schueider). 18. Nehris microps Cuvier et Valenciennes. Les Poissons appartenant aux trois families des Gym- notidse, des Siluridse, des Characinidse, sont tous des eaux douces, nous ne voyous même pas ici pour la seconde de représentants du groupe des Arius, dans lequel se trouvent souvent des espèces marines ou tout au moins d'eaux saumatres , comme il en est cité dans la liste de M. Kappler. \j Achirus faciatus ^ Ie Batrachus surinamensis^ V Ancylodon ancylodon^ Ie Nehris microps, sans doute V Engraulis spinifer^ sont plutót marins, Cependant les deux Sciénoïdes , comme nombre de poissons de cette familie , pourraieut bien acci- dentellement remonter dans Ie fleuve, on peut en dire autant du Mugil incilis. MM. C. et R. Eigenmann dans leur Catalogue des Poissons des eaux douces de l'Amérique du Sud , ne citent cependant pas ce dernier, non plus que V Ancylodon ancylodon, ni Ie Nehris microps. Si nous comparons cette liste a celles donuées par Muller et Troschel , et par M. Kappler, ce qu'on trouvera rappelé a propos de chacune des espèces, on voit qu'environ huit espèces n'ont pas été signalées par ces auteurs, mais sur ce nombre trois seulement seraient nouvelles pour la faune a savoir: Loricaria filamentosa Steindachner, espèce récemment décrite du Rio Magdalena; Achirus fasciatus Lacépède , qui n'avait pas encore été signalé d'un point aussi meridional; Mugil incilis Hancock, celui-ci pourrait bien avoir été confondu jusqu'ici avec Ie Mugil hrasiliensis Agassiz. Notes from the Leyden ÜVIuseum , "Vol. 'X.'X.. DE LA GUYANE. Ö 1. Sternopygus carapo (Linué). Günther, 1870, T. VIII, p. 7. Un exeraplaire long de 330 millimetres. Muller et Troschel ne signaleut pas cette espèce, elle se trouve indiquée par M. Kappler. 2. Carapus fasciatus (Pallas). Günther, 1870, T. VIII, p. 9. Un exemplaire long de 300 mm. Muller et Troschel ne sigualent pas cette espèce , elle se trouve indiquée par M. Kappler. 3. Pimelodus holomelas Günther. Günther, 1864, T. V, p. 120. D. I, 6; A. 9. Ce Pimelode a Ie prolongement occipital sensiblement plus long que large, sans qu'il atteigne toutefois Ie bouclier interépineux , la seconde épine de l'épiptère est faible et sensiblement plus courte que les rayons articulés qui la suivent. L'adipeuse tres longue (79 mm.) est comprise environ 2'/^ fois dans la longueur du corps. Tous ces caractères Ie rapprochent des espèces du groupe du Pimelodus Seba' Cuvier et Valenciennes et particulière- ment du Pimelodus holomelas Günther, son adipeuse com- men9ant a une certaine distance de l'épiptère rayonnée, et la formule de l'anale étant la même. Toutefois il diffère de toutes par l'absence de serratures au bord antérieur de l'épine pectorale, qui ne peut, par conséquent, passer pour deutelée sur les deux bords. Ceci justifierait-il une distinc- tion spécifique? j'avoue que ne trouvant pas d'autre ca- ractère différentiel , je crois devoir rester dans Ie doute. Les deux exemplaires de la collection, a peu prés de même taille, mesurent 200 + 42 = 242 millimetres et sont done plus petits que l'individu type, lequel atteignait 305 Notes from the Leyden Museum, Vol. XX. 6 ICHTHYOLOGIE millimetres (12 pouces), l'absence des serratures ne peut alors , en tous cas , être attribuée a l'age , comme Ie fait a été constate chez d'autres Siluroïdes '). Ce poisson venait de l'Essequibo (Günther, 1864, T. V, p, 120), c'est a dire des mêmes regions. Nou cité par Muller et Troschel, ni par M. Kappler. MM. C. et R. Eigenmaun ne croient pas cette espèce distincte du Pimelodus Sebce Cuvier et Valenciennes , dans ce cas elle aurait été trouvée par les premiers de ces au- teurs dans toute la Guyane anglaise. 4. Callichthys callichthys (Linné). Günther, 1864, T. V, p. 226 (sous Ie nom de: C. asper Quoy et Gaimard). Un individu mesuraut 125 -|- 30 = 155 mm. Je ne trouve a la dorsale rayonnée que la formule I. 7 et pour les boucliers latéraux 27 a la rangée supérieure , 26 a la rangée inférieure, il y a de plus un petit espace nu entre les derniers boucliers et la base de l'adipeuse. L'individu présente des caractères mixtes entre Ie Callichthys callichthys (Linné) , auquel je crois devoir Ie rapporter, et Ie G. aj/inis Günther; ces deux espèces sont évidemment des plus voisines. Non compris dans les trois espèces citées par Muller et Troschel (C. ccelatus C. V., C. exaratus M. & T., C. pictus M. & T. = C. longijilis C. V.) mais cité par M. Kappler. 5.

Kuer a déja fait remarquer (1854, p. 80), que Ie point oü se réunissent les crêtes de la ligne laterale peut, suivant les individus, varier. lei nous Ie trouvons vers la 16e ou 17e écaille et non a la 20e comme l'ont dit, d'une ma- niere trop absolue, les anciens auteurs.

C'est a ce Loricaire que je crois devoir rapporter trois exemplaires, raesurant pour Ie corps 142 mm. a 164 mm. (aucun d'eux n'a l'uroptère intacte). lis en présentent les principaux caractères tels qu'on les trouve dans l'excellente description et Ie tres beau dessin donnés par M. Steindachner. Toutefois la disposition striée du bord postérieur du bouclier céphalique est loin d'etre aussi nette que Ie montrent les figures ou pour mieux dire n'existe pas. Le plastron abdominal est bien formé de scutelles sur quatre rangées, mais ces rangées ne com- prennent aux séries externes qu'une suite de 5 a 7 écail- les, au lieu de 12. Enfin le corps est sensiblement plus court, la distance du rostre a la base de l'aiguillon dorsal Notes from the Leyden Museum, "Vol. XX, 8 ICHTHYOLOGIE faisant Ie ^j^ de la longueur, abstraction faite de Turo- ptère, au lieu des '/jj et raême presque ^/^ chez les jeunes. Malgré ces petites differences, la forme du museau, la disposition des dents , la presence et la dimension de l'échan- crure post-orbitaire , surtout les prolongements tentaculi- forraes qui ornent Ie bord des voiles labiaux , établissent des rapports , qui me paraissent justifier l'assimilation proposée. Aucun des exemplaires ne présente en arrière sur les cótés de la tête de soies sensibles, ce seraient done des individus femelles. On remarque sur tous , dans l'espace en triangle tres allonge forme par les carènes latérales avant leur reunion, une série de taches sombres au nombre de cinq , régulièrement espacées. 9. Aspredo batrachus Linné. Günther, 1864, T, V, p. 268. Günther, 1864, T. V, p. 269 (A. sicyephorus C. V). Sept exemplaires dont la taille varie de 300 -|^ 18 ^ 318 mm. jusqu'a 180 -|- 15 = 195 mm. Par la longueur de la tête, mesurée jusqu'a l'extrémité du prolongement interparietal , supérieure au quart de la longueur totale (y compris la caudale par conséquent), ces Asprèdes se rapportent plutót a V Aspredo sicuephorus de Cuvier et Valenciennes. Ce caractère ne me parait pas avoir une valeur spécifique. Un autre particularité indiquée par les auteurs de l'Histore des Poissons pourrait être regardée comme plus importante a savoir : Ie pourtour des lèvres et Ie dessous des barbillons maxillaires garnis de points verruqueux ; mais précisément dans cette série d'individus on trouve toutes les transitions entre iles lèvres tres papil- leuses et des lèvres lisses ou presque lisses. L'Asprède a veutouses ne peut done être regarde au plus que comme une variété de l'Asprède batrachoïde. MM. C. et R. Eigenmann nomment cette esipèce Aspredo aspredo Linné; l'auteur du Systema Naturae ayant anté- Notes from the Ley den Miaseum., Vol. XX. DE LA GUYANE. 9 rieurement employé l'épithète de 6a^rac/ms, cette designation spécifique mérite d'etre conservée bieu que ce ne soit pas celle des dernières editions. L'espèce est signalée par Muller et Troschel (sous Ie nom d^Aspredo la>vis Cuvier et Valenciennes) et par M. Kappler. 10. Aspredo cotylephorus (Bloch). Güotber, 1864, T. V, p. 269. Un individu long de 230 ^ 18 = 248 ram. L'espèce ne se trouve pas citée par Muller et Troschel ni dans la liste de M. Kappler. 11. Aspredo tihicen Cuvier et Valenciennes. Günther, 1864, T. V, p. 270. Deux individus a peu prés de mênie taille mesuraut en- viron 192 4- 16 = 208 mm. L'un d'eux (feraelle d'après M. Günther) présente a la region abdominale ces prolongements spéciaux que Bloch a Ie premier fait connaitre, Cette observation porterait a quatre Ie uombre des espèces chez lesquelles aurait été authentiquemeut reconnue la pre- sence de ces singuliers appendices, les précédentes étant les Aspredo cotylephorus (Bloch), A. sicuephorus Cuvier et Valenciennes, A. hatrachus Linné ^). Grace a M. Günther c'est sur ce dernier que nous pos- sédons Ie plus de renseignements, par l'examen qu'il a pu faire d'un tres remarquable individu appartenant a la col- lection du British Museum. Ce savant ichthyologiste en a donné une étude détaillée dans Ie \^ volume de son Cata- logue ~), ses conclusions ont été résumées dans l'Introduction 1) On a vu plus haut qu'on peut élever des doutes legitimes sur la distinc- tion établie entre ces deux dernières espèces. 2) A. Günther, 1864. Catalogue of the Fishes in the British Museum, T. V, p. 268. Notes from the Leyden ÜMuseum , Vol. XX- 10 ICHTHYOLOGIE a l'étude des Poissons, oü se voit de plus une tres belle figure de ce curieux specimen ^). Suivant eet auteur on doit supposer , qu'a l'époque de la reproduction , la partie ventrale aplatie de la femelle prend une structure spongieuse, c'est dans ce tissu mou et en quelque sorte aréolaire , que celle-ci par pression fait péné- trer les ceufs au moment de la ponte. «Les espaces inter- médiaires sont remplis par les appendices mentionnés, dont les dilatations terminales jouent un róle essentiel pour maintenir les ceufs en position.» Une fois ceux-ci éclos Ie tegument reprend son aspect habituel , les prolongements , qui ne seraient en somme qu'un derive du tissu spongieux, persistent encore quelque temps, puis finissent eux-mêmes par disparaitre , tout revenant a Tétat normal. L'étude d'un certain nombre de specimens du genre Js- predo conserves dans la collection du Muséum: A. cotyle- phorus (= A. sex-cirrhis Cuvier et Valenciennes), A. sicue- phorus, mais en particulier de VA. tibicen provenant du Berbice et dont l'état de conservation est de beaucoup meilleur que celui de tous les autres exemplaires , me con- duit a des conclusions différentes. Comme toutefois en l'ab- sence d'observations directes sur Ie vivant, on ne peut encore qu'émettre des hypotheses plus ou moins plausibles, j'exposerai en premier lieu les résultats de l'étude anato- mique tant descriptive que générale , pour indiquer ensuite les consequences qui paraissent pouvoir en être tirées au point de vue physiologique. Les différents individus qui ont été jusqu'ici figures ou observes , sauf celui du British Museum , dont il vient d'etre question , ne présentent ni les uns ni les autres d'ceufs bien reconnaissables et l'on n'observe que les appendices singuliers que Bloch a fait connaitre. Ceux-ci ne se rencontrent jamais qu'a la face inférieure du corps, principalement sur Ie tegument abdominal, s'étendant quelquefois au dela de l'insertion des pectorales en avant, au dela de celle des 1) A. Günther, ]880. &n introduction to the study of Fishes, p. 160« et fig. 72. Notes from the Leyden Mixsenm, Vol. XX. DE LA GUYANE. 11 ventrales en arrière , j'en vois même sur la base du pé- doncule caudal chez V Aspredo cotylephorus du Muséum. On remarque aussi que eet accident peut atteindre la face in- férieure des nageoires paires elles-mênaes , mais , pour les pectorales, aux rayons mous et a la membrane interradiale, non a l'épine osseuse , sur laquelle du moins je n'en vois pas , en ayant égard soit aux figures données par les au- teurs, soit aux exemplaires que j'ai eu l'occasion d'examiner. Pour préciser davantage , sur Ie bel exemplaire du Musée de Leyde, Ie ventre porte environ une soixantaine de ces appendices , je n'en vois aucun sur les pectorales , mais sur les ventrales on en observe 8 du cóté droit , 5 a 6 du cóté gauche. A l'état de complet développement, et il convient pour les étudier de choisir parmi ceux de la peau de l'abdomen , l'appen- dice se compose de deux parties dont l'ensemble est comparable a un champignon, aussi les designa- tions de pied et de chapeau peuvent-elles leur être appliquées. Le premier (a) est plus ou moins cylindrique, se dilatant quelque peu vers la base, qui est continue avec le tegument , dont il parait être et est en effet une dépendance , sa longueur irait jusqu'a 3.9 mm. (mesure approximative) le plus grand diamètre ne dépasserait guère 1 mm. ; il est bon de remarquer, et ceci s'applique a l'ensemble des observations ici consignees , qu'il s'agit de sujets conserves depuis plus OU moins longtemps dans l'alcool. Le chapeau {b) en conti- de la coquille de l'oeut' nuité directe avec le pied par le centre de sa face adhérente, est discoïde, aplati, a bords arrondis , légèreraent Notes from the Ley den Museum, Vol. XX.

Mais tous les appendices ne sont pas aussi parfaits, même sur un individu donné. Un certain norabre sont ré- duits au cliapeau immédiatement applique sur Ie tegument auquel il adhère par sa partie centrale , c'est a dire qu'ils sont sessiles. Chez d'autres au contraire, Ie pied plus aminci vers son extrémité, conique, au lieu d'un cha- peau discoïde tres développé ne porte qu'un petit bouton en sphere. üne autre particularité importante , qui s'observe tres clairement sur l'exemplaire du Musée de Leyde , mais qu'on retrouve sur d'autres individus une fois l'attention fixée sur ce fait, c'est la presence, sur les cupules sessiles et sur les chapeaux bien complets , de lambeaux lamel- leux (c) tres minces et d'une grande transparence, qui s'y rencontrent d'une maniere, on peut dire, constante, sur Ie sujet bien conserve. Examines a un fort grossissement ces lambeaux apparaissent comme une membrane hyaline a déchirure nette, s'ils sont replies sur eux-raêmes, ce qui est frequent, Ie point de la duplicature montre une ligne a double contour, permettaut d'apprécier l'épaisseur de la membrane, laquelle épaisseur serait de 10 ;Ct a 13 pt. Sur cette membrane se trouve a l'intérieur un revêtement d'a peine 2 (jl d'épaisseur, irrégulièrement depose, manquant parfois, de sorte qu'il en résulte des inégalités d'épaisseur, ce qui prod uit sur la membrane vue a plat des accidents d'aspect cratériforme, les diamètres mesurés de quelques uue de ces depressions, toujours plus ou moius régulière- ment circulaires, m'ont donné les dimensions extremes 93 ^ et 24: ,64. Il est impossible de ne pas croire que ces lambeaux proviennent d'une membrane coquillère, enveloppe de l'oeuf, la couche interne étant forraée sans doute de debris de la substance vitelline restés adherents après l'évacuation du contenu. Il faudrait , d'après cette observation , admettre que les oeufs, dans les individus dont il est ici question, n'étaient Notes from tlie Leyden JMuseum, Vol. XX. DE LA GUYANE. 13 pas places entre les appendices fungiformes mais sur leur extrémité dilatée. Au point de vue histologique la structure de ces oopho- res est tres simple, c'est d'ailleurs aussi bien pour Ie pied que pour Ie chapeau celle du tegument. La partie centrale est formée de fibres conjonctives assez lachement unies, comme dans la partie profonde du derme , on y distingue des vaisseaux. Les fibres deviennent ensuite plus serrées, formant un tissu d'autaut plus dense qu'on se rapprocbe davantage de la partie superficielle. Il doit y avoir un re- vêtement épidermique , mais je dois avouer que je n'ai pu en constater l'existence , ce qui n'a pas lieu de surpren- dre étant données les conditions dans lesquelles les études ont été faites. En se rappelant les formes diverses, signalées plus baut, de ces appendices, l'bypotbèse qui me parait se présenter naturellement a l'esprit, c'est qu'au moment de la ponte les oeufs doivent se fixer au tegument abdominal et cela sans doute, comme pour les oeufs de beaucoup d'autres poissons , par suite de la presence a leur surface d'une matière plus ou moins gluante, leur permettant de se colier sur les surfaces avec lesquelles ils se trouvent en contact. Ce qui induit a penser que la faculté adhesive reside dans l'oeuf plutót que dans les parties qui Ie supportent, c'est la maniere jusqu'a un certain point indiöérente suivant laquelle ils se fixent en dehors de la region abdominale , particulièrement sur certaines nageoires. Le tegument en se gonflant au point d'attache forme- rait une cupule de reception, le chapeau; un peu plus tard se produirait une elongation des tissus sous jacents, d'on résulte la tige centrale formant le pied de l'appendice oophore fungiforme. Après l'éclosion l'enveloppe de l'ceuf resterait adhérente au chapeau, puis se détacherait soit spontanément , soit par la retraction de celui-ci passant a l'état de simple boutou , enfin le pied reviendrait également sur lui-même rentrant en quelque sorte dans le tegument, qui reprend ainsi son aspect normal. Notes from the Ijeyden IMuseum, Vol. XX. 14 TCHTHYOLOGIE La raarche du phénomène est-elle bien celle que je pro- pose ici hypothétiquement ? des observations sur Ie vivant pourront , sans doute , seules decider la question , car il serait aussi possible que l'ceuf effectuat son développement sur uue cupule sessile et que Ie pied se produisit ensuite dans la marcbe de redintegration des tissus, ce qui pourrait expliquer la disposition observée sur l'exemplaire du British Museum préseutant a la fois des oeuf's encore adherents , entremêlés a des appendices fungiformes. En tout eas , d'après les faits ici consignes, ceux-ci ne seraient pas des organes protecteurs des ceufs mais de véritables oophores. Muller et Troschel ainsi que M.

Cet auteur indique en passant Ie caractère fourni par l'écarteraent des narines. Elles partagent en effet assez exactement Ie museau par tiers , au lieu d'etre placées Tune contre l'autre, comme elles Ie sout d'ordinaire cbez les Muges et genres voisins , particularité tres importante a noter.

En effet si les dents a la mandibule sont nombreuses (au moins 50) ciliiformes, unisériées, difficile- ment visibles , les dents inter- maxillaires sont au contraire peu nombreuses, une douzaine environ de chaque cóté, presque perceptibles a l'oeil nu, recourbées, ces animaux seraieut done a la rigueur tout aussi bien places dans Ie genre Myxus, auquel je les avais rapportés d'abord. L'espèce ne parait pas être tres commune , M. Güntber la cite de la Guyane anglaise et du Chagres , MM.

La confusion ordinairement faite avec Ie Mugil hrasiliensis, ne permet pas de savoir si cette espèce n'avait pas déja été trouvée a la Guyane. 16. Batrachus surinamensis Bloch-Scbneider.

Ligne laterale tres nette, bien que, comme on Ie verra plus loin, l'écaillure en soit assez imparfaite. On y compte uue cinquante de ce que j'appellerais volontiers des noeuds, mais Ie nombre des rangées d'écailles est plus grand et peut être évalué a 70 (comme l'indique la formule donnée plus baut). Les nageoires impaires sont fortement écailleuses et la ligne laterale se prolonge jusqu'a l'extrémité de la caudale. On remarquera que les formules ici données dif- férent un peu de celles qu'avaient trouvées Cuvier et Va- lenciennes, mais il ne faut pas, je crois, dans Ie groupe des S ei sen id 88, attacber a ce fait une trop grande im- portance. La nature des écailles varie suivant les points que l'on considère. Sur les flancs, au dessous de la ligne laterale, elles sont en quadrilatères a cótés plus ou moins convexes, allongées d'avant en arrière ; foyer central ou sub-central postérieur ; les cbamps antérieur et latéraux converts de crètes concentriques , interrompues sur Ie premier par des sillons centripètes; des festons au bord radiculaire; Ie cbamp postérieur, triangulaire, peu étendu, porte des spinules bien développées , sur plusieurs rangs; ces écailles sont done d'un type nettement cténoïde-polystique. Sur la joue ces organes sont plus OU moins exactement circulaires , a foyer central régulièrement entouré de crètes concentriques ; ils sont done d'un type cycloïde. Les tubes de l'appareil lateral paraissent membraneux et sont proteges par une multitude de petites écailles cycloïdes, disposition déja signalée cbez d'autres Scisenidse ^). Au dessus de la ligne laterale la forme des écailles est 1) Vaillant et Bocoiirt, Mission scientifique au Mexique et dans l'AmériqHe centrale. — Poissons, p. 172, PI. VIII, fig. Ic.

On sait que les auteurs de l'Histoire naturelle des Pois- sous décrivent et figurent cette espèce, d'après un exem- plaire envoyé de Surinam au Musée de Berlin , c'est a dire de la Guyane hollandaise. Pendant de longues aunées l'animal n'avait pas été revu lorsqu'en 1875 M. Steindachner annou9a l'avoir trouvé dans une collection faite a Panama, c'est a dire sur l'autre ver- sant américain , dans l'Océan pacifique. Le fait fut con- firmé par MM. Jordan et Gilbert en 1882. Toutefois ces différents ichthyologistes s'étaient bornés a une simple mention sans entrer dans aucun détail, en 1889 seuleraent, MM.. Jordan et C. H. Eigenmann, revenant sur ce point, ont donné une description des individus de l'A-mérique occidentale dans un travail tres complet auquel je renvoie pour les indications bibliographiques ').

D'après l'individu appartenant au Musée de Leyde, que j'ai entre les mains et dans un état d'admirable conservation , cette maniere de voir ne me parait pas exacte. On trouve dans l'excellente description fournie par MM. Jordan et C. H. Eigenmann, que Ie Nehris du Pacifique a les dents man- dibulaires unisériées , les écailles cycloïdes , tandis que Ie Nehris microps a les dents plurisériées a l'une et l'autre raachoire , les écailles , en grande partie au moins , nette- ment ctéuoïdes; Ie premier également, autant qu'on en peut juger, aurait Ie maxillaire moins prolongé en arrière puisqu'il s'arrêterait au dessous du bord postérieur de l'orbite. Les deux poissons doiveut par suite être considérés comme spécifiquement distincts ^) et l'on pourra designer Ie Nehris de rOcéan pacifique sous Ie nom de N. occidentalis. Ce dernier, d'après M. Steindachner et d'après MM. Jordan et C. Eigenmann parait exclusivement marin , Ie Nehris microps, a en juger par l'exemplaire de la rivière Berbice, serait plutót dul^aquicole, mais Ie fait n'a rien d'étonnaut dans la familie des Sciénoïdes, oü des espèces voisines, parfois une même espèce, peuvent indifférerament se rencontrer dans l'un ou l'autre milieu.

CEPHALOPODES. 21 NOTE IL SUR QUELQUES CEPHALOPODES DU MUSÉE ROYAL DE LEYDE ET DESCRIPTION DE TROIS ESPÈCES NOÜVELLES PAR M. L. JOUBIN, Professeur a TUniversité de Rennes (France). M, Ie Dr. R. Horst, Conservateur au Musée Royal d'his- toire naturelle de Leyde, a bieü voulu me coiifier la deter- mination des Céplialopodes de ce Musée. Je Ie prie de vouloir bien agréer tous mes remerciments. Parmi les nombreux échantillons que j'ai examines, j'ai rencontre trois espèces qui me paraissent nouvelles ; on en trouvera dans cette Note une courte description. Ce sont: Octopus Horsti, Octopus Hoeki et Sepioteuthis Sieholdi. En outre j'ai réuni ici diverses remarques sur quelques unes des espèces qui composent Ie Catalogue que l'on trouvera prochainement, au complet, dans une autre publication. Puisque l'occasion s'en présente je crois devoir vivement recommander aux voyageurs l'emploi du Formol a 3°/o pour la conservation des Cépbalopodes ; ils y gardent leur forme , leur couleur, leur transparence , pendant plusieurs années, et ensuite Timmersion dans l'alcool a 75° ne les leur enlève plus. W suffit pour employer ce liquide d'en mettre dans de l'eau, douce ou marine, environ 30 centi- metres cubes par litre, et d'y plonger les Cépbalopodes en Notes from tlie Leyden Museum, Vol. XX. 22 CEPHALOPODES. ayant soin de boucher ensuite herraetiquement le recipient qui les renferme. Ce procédé est beaucoup moins couteux que Talcool et moins encombrant puisqu'avec un litre de formol on peut faire 30 a 35 litres de liquide. Il serait vivement a désirer que les voyageurs hollandais continuent a apporter au Muséum de Leyde un grand nombre de Céphalopodes, mêmes communs; il serait alors possible, a cóté d'uu type de chaque espèce , de disposer d'une série d'échantillons de la même espèce de provenance différente. On pourrait dans ces conditions, étendre le tra- vail de comparaison des variétés locales , que je n'ai pu qu'ébaucher, ce qui amènerait vraisemblablement a la sup- pression d'un certain uorabre d'espèces et serait d'un grand intérét zoogéographique. Octopus macropus Risso (= O. Cuvieri d'Orbigny). Un échantillon, de Djeddah (J. A. Kruyt), est remarquable, malgré son piteux état , parce qu'il représente tres exactement V Octopus Lechenaulti d'Orbigny. Cet auteur a d'ailleurs, supprimé lui-même cette espèce et l'a rattachée a Octopus macropus. Les ventouses charuues sont tres irrégulièrement placées sur les bras; on eu voit 5 ou 6 de suite sur un seul rang, comme chez Eledone; plus loin au contraire elles sont tres serrées, et disposées sur deux rangées alternantes. Octopus granulatus Lamarck var. rugosa Bosc. ün exemplaire interessant, de Bahama (A. de Haas), parce que 7 de ses 8 bras sont en voie de reconstitution plus ou moins avancée par bourgeounement. Octopus areolatus de Haan, 1885. Dans un exemplaire de moyenne taille, bien conserve (von Siebold, Japon), la tache oculiforme garde encore son éclat métallique. Octopus ocellatus Appellöf. Une jeune femelle, pleine de gros oeufs, et dont le corps "Notes from the Leyden üMuseum, "Vol. XX. CEPHALOPODES. 23 est granuleux , ue porte pas de cirrhes orbitaires ; ses yeux sont plus saillauts que dans le type decrit par Appellöf (Amboine , Hoedt). Octopus fontanianus d'Orbigny. Un echautillon de TOcéaa Indien (Reinwardt) est iden- tique, par la disposition de ses veutouses, a la description et a la figure données par d'Orbigny. Mais celui-ci I'indique comme habitant seuleraent la cote de l'Amérique du Sud , tandis que Techantillon du Musee de Leyde provient de I'Oceau Indien. Octopus Horsti, n. sp. Octopus de grande taille provenant de Djeddah (J. A. Kruyt), en assez mauvais état. Cette espèce est interes- sante et je la dédie a Mr. Horst, du Muséum de Leyde. Le corps est gros , ovale , de couleur foncée. Les bras sont tres développés, et l'animal par sa forme générale rappelle O. vulgaris. La peau est entièrement lisse , et présente seulement sur chaque oeil un gros cirrhe postérieur et un petit antérieur. Une membrane natatoire unit les bras et se prolonge sur toute leur longueur. Sur la base de la couronne tentaculaire , de chaque coté , en avant de l'oeil et un peu plus bas , vers la racine du 2^ bras ventral (3^) on voit une grosse tache noire ovale. — Tout le long des bras, surtout dorsaux, sur leur moitié ventrale seule- ment , entre chaque veutouse , on distingue une grosse zébrure noire, irreguliere. Quand on ne voit qu'un cóté du bras , cela ressemble a une série de bagues noires qui y seraient enfilées. — Cela ne commence qu'au point oü finit la membrane palmaire. Les bras, charnus a la base, deviennent bientót filiformes. Les ventouses y sont tres enfoncées dans la peau, devien- nent rapidement tres petites et tres nombreuses, car j'en ai compté 350 sur un seul bras dorsal de 52 centimetres de longueur. Les 4 premières sont sur un seul rang. — Bras 1.4.8.2. Notes from tlae Leytlen JMuseum , Vol. XX. 24 CEPHALOPODliS. Le siphon est long et cylindrique. Cette espèce présente uue certaine analogie avec Octopus ocellatus Appellöf mais en diffère par la forme générale du corps, la longueur des bras, le nombre des ventouses , et I'aspect de la membrane palm aire. Octopus Hoekig n. sp. Cette nouvelle espèce d'Octopus a été rapportée d'Amboine par Schorel, Je me permets de la dédier a notre savant coUègue P. P. C. Hoek. Voici les caractères distinctifs de ce Céphalopode. Corps ovale , rétréci en haut , surmonte d'une tête tres étroite. Yeux saillants. Bras relativement courts, a ventouses enfoncées dans le tissu mou et d'aspect infiltré. L'ouverture palléale intéresse a peu prés toute la largeur du haut du corps. Siphon petit, ne dépassant pas le niveau des yeux. — Couleur du corps blanchatre, sur le milieu du dos et sur la tête violet foncé. Bras 1.2.4.3. — Membrane palmaire bien développée entre les bras ventraux, diminuaut a mesure qu'on se rapproche du dos ; cette palmure, blanche partout ailleurs , est rendue violette par de tres curieux petits organes pig- mentés , entre les bras dorsaux , et la moitié dorsale de la 2e palmure (entre le ler et le 2^ bras). Ces membranes s'éten- dent par des prolongements minces le long des bras. La peau est entièrement lisse, le corps mou et flasque. On trouve un seul cirrhe long et grêle susorbitaire. — Sur chaque bras les 3 premières ventouses sont disposées sur un seul rang, les autres alternent, et sur les 2 bras laté- raux les plus grandes sont de la S'^ a la ll*'. La Ir*^ de chaque bras contribue a former un cercle saillant peribuc- cal. La longueur totale du corps est de 230 millimetres. Sepia Filliouxi Lafontaine. Un gros exemplaire male du Cap (Horstock). C'est la première fois que cette espèce est signalée au Cap. Mais a a>fotes from the Leyden IMuseuin, Vol. XX. CEPHALOPODES. 25 cause de la grande ressemblance (pour ne pas dire identité) entre cette espèce et S. officinalis , il est probable que Ton trouverait des Filliouxi parmi les officinalis deja counus. Sepia aculeata van Hasselt. Un lot d'une quinzaine d'individus étiqueté St. Vincent, Nassau harbor, Bahama (A. de Haas). Cette espèce est jusqu'a present considérée comme exclusivement Indo- Malaise, et c'est pour la première fois qu'elle est signalee dans I'Atlantique. Le repli postérieur nacre n'apparait nettement que chez les individus ayant plus de 10 centi- metres , il est a peine indique chez les jeunes. Il me parait tres probable que S. indica d'Orbigny est identique a cette espèce. Sepiella iiurmis (van Hasselt). Trois petits échantillons assez mauvais de Timor. Sur l'un d'eux on constate nettement un caractère qui u'est presque jamais conserve: une série de gros points colorés situés sur la face dorsale de la nageoire, le long de son insertion , et dimiuuant de la queue vers la tête , absolu- meut comme dans la figure 2 , planche 22 , de d'Orbigny. Genre Sepioteuthis Blainville , 1825. L'examen des nombreux exemplaires appartenant au genre Sepioteuthis qui composent la collection du Muséum de Leyde , m'a amené a critiquer les subdivisions admises généralement dans ce genre. On peut conserver, provisoirement du moins, les deux sections basées sur la presence ou l'absence de ventouses sur la membrane buccale. Mais la subdivision suivante, établie sur la presence ou non de bords épaissis a la plume, doit être abandonnée. Je puis dire que tous les Sepioteuthis que j'ai examines , a quelqu'espèce qu'ils appar- tienneut, présentent ces épaississements tres nets chez cer- IVotes from the Leyden ÜMuseum, Vol, XX. 26 CEPHALOPODES. tains individus, moins nets chez d'autres, etendus sur tout le bord ou seulement limites au bas. Ces differences se trouvent dans la mêrae espèce, et dependent, a ce qu'il m'a semble, surtout de la taille des individus, conséquem- ment de leur age, peut-être même de leur sexe. Les épais- sissements marginaux ne peuvent servir en rien a deter- miner les espèces , et même il ne faut pas tenir compte de ce caractère qui peut, par ses variations individuelles , conduire a des erreurs de diagnose. Il en est de même de la forme générale de la plume qui peut être plus ou moins mince, étroite, large, droite, courbée , selon les variations sexuelles , de taille et d'age des individus. D'autres influences locales doivent certaine- ment contribuer a modifier eet organe, mais il faudrait pour les préciser , étudier un plus grand nombre d'échantillons. Sepioteuthis lessoniana Férussac et d'Orbigny. [z= S. mauritiana Quoy et Gaimard). J'ai examine un grand nombre d'échantillons de différents localités (Java, Timor, Morotai, iles Obi, Océau Indien, Cap) se rattachant soit a Sepioteuthis lessoniana Férussac et d'Orbigny, soit a Sepioteuthis mauritiana Quoy et Gai- mard. J'ai acquis la conviction que ces deux espèces n'en font qu'une. Si l'on compare les diagnoses, assez vagues et défectueuses d'ailleurs , proposées par les auteurs pour ces deux espèces , on voit immédiatemeut qu'aucuu caractère différentiel sérieux ne s'y remarque. Le bord de la plume est épaissi chez les deux types (j'ai dit d'autre part combien ce caractère doit être considéré comme fugace) ; la longueur proportionnelle des bras est ideutique de formule; les dents cornées des ventouses sont tout-a-fait semblables , car les légères diffe- rences qui ont été signalées par les auteurs peuvent se rencontrer jusque sur le même individu, et sont correla- tives de sa taille. Les differences pen sensibles , si tant est qu'elles soient appréciables, dans la forme des nageoires in- Notes from the Leyden Museum, Vol. XX. CEPHALOPODES. 27 diquées par d'Orbigny, ne correspondent même pas au texte explicatif de I'auteur. II n'y a pas de difference entre les écbantillons recueillis au Cap , dans l'Océan Indien , ou dans I'Archipel Indo-Malais. Je suis en outre porté a croire que certaines determinations n'ont été basées que sur la diffe- rence de provenance des individus. Dans ces conditions il me parait absolument justifie de considerer comme syno- nymes les deux espèces de d'Orbigny et de Quoy et Gai- mard. Le nom lessoniana etaut le plus ancien prend done la place de mauritiana. — Je ne serais pas autre- ment surpris que S. australis ne soit également destine a se fondre avec S. lessoniana; mais je ne veux pas l'aöir- mer actuellement. Sepioteuthis loliginiformis d'Orbigny. Je rapporte a Sepioteuthis loliginiformis d'Orbigny un ecbantillon en assez mauvais état , recueilli a Djeddah , mer Rouge (J. A. Kruyt). Cette espèce, peu connue et tres mal carac- térisée , présente les particularités principales suivantes : Les ventouses de la membrane buccale sont par petits groupes de 2 OU 3 situées tout-a-fait a la pointe des dents de cette membrane. La nageoire, étroite en avant, est arrondie en arrière. La plume est mince. Les bras longs et grêles présentent l'ordre d'importance suivant: 3.4,2.1. Le siphon est retenu a la tête par les 2 ligaments ordinaires, mais en outre par un troisième median. Les chromatopbores sont tres gros sur les cótés, plus petits sur le milieu du ventre. Sur la face ventrale de la tête, entre les yeux, il u'y en a que quel- ques uns ovales , tres espacés , fort gros. Sur les tentacules ils sont aussi de grande taille, ovales et allonges. Sepioteuthis Sieboldi, n. sp. Il me semble nécessaire de créer une nouvelle espèce de Sepioteuthis que je me permets de nommer aS. Sieholdi. Voici les raisons qui m'y conduisent. Les auteurs comme Notes from the Leyden IMuseum, Vol, XX. 28 CFPHALOPOÜES. Férussac et d'Orbigny, Gray, Tryon qui out écrit sur la specification des Sepoteuthis ont posé comme caractère im- médiatement décisif de S. lunulata , la presence sur la face dorsale de la uageoire d'une série de taches rondes régu- lièrement espacées ; puis ils posent en principe que les bras , longs et fort grêles, sont dans l'ordre d'importance suivant 3.2.4.1. C'est bien en effet ce que l'on observe dans les individus qui répondent au type lunulata. Mais on en trouve d'autres qui leur ressembleut au premier abord par les taches de la nageoire; cependant ils ont, comme les S. lessoniana les bras dans l'ordre 3.4.2.1; et de plus ces bras sont gros et courts , ce qui entraine une tête plus grosse et une difiéreuce sensible dans la forme générale du sac visceral. Ces caractères sont plus que suffisants , pour établir une section dans les Sepioteuthis portant des taches sériées sur leurs nageoires: 1°. S. lunulata a bras grêles 3.2.4.1, 2^.5'. Sieboldi a bras gros et courts 3.4.2.1.

Resembling A. laevicollis Lansb. from Java and Sumatra, but at once distinguished from that species by the clypeus which is shorter, deeply emarginate in the middle and, between the eyes, separated from the face by a deep sulcus. Moreover the punctuation ou the elytra is stronger. Length 7,5 — 8,5 mm. — Broadly ovate; glabrous, black, the head, prouotum and scutellum with green and purple or coppery tinges, the antennae and palpi pale ferruginous, the tarsi pitchy brown. The head is large, the clypeus broadly emarginate in the middle, the emargination with rounded lateral angles, the anterior margin reflexed ; a deep sulcus between the eyes separates the clypeus from the face; the clypeus is rather remotely covered with large punctures ; the punctures on the face are fine and distant. The prothorax is strongly transverse and very convex ; the pronotum is distantly covered with punctures which are a trifle larger than those on the face ; a small impres- sion is present at the basal margin in front of the basal angles of the scutellum; the sides are rounded just behind the middle when viewed laterally, the basal angles are obtuse, the anterior ones acute but not protruding. The Notes from the Leyden IVIiiseuiri, Vol. XX. 30 APOGONIA SÜLCATICEPS. scutelluni is smooth, impunctate, and of a broadly triangular shape. The elytra are strongly punctured, with two very distinct narrow costae ; the third costa is not discernible as the punctures on the sides of the elytra are in regular rows. The propygidium is rugosely punctured ; the punctures on the pygidium are large but wider apart. The punctuation on the sides of the metasternum agrees with that of the abdomen; the latter (with the exception of the propygidium) is surrounded by a raised line. The anterior tibiae are minutely tridentate. Hah. East Sumatra: Serdang (Dr. B. Hagen); Deli (Ed. Veen). — Leyden Museum. Apogonia Blanchardi^ n. sp. A deep black species without metallic lustre, which is, according to the authentic specimens in the Paris Museum, erroneously identified by E. Blanchard (Cat. Coll. Ent. 1850, p. 228) as A. rauca Fabr. Length 9,5 — 11 mm. — Ovate, glabrous, shining black, the apex of the elytra and the two basal ventral segments, however, opaque ; the antennae and palpi pale ferruginous ; the under surface and legs sprinkled with pale coloured setae. The clypeus is rather long, almost regularly rounded, faintly truncate in the middle, and separated from the face by a distinct suture; the anterior margin is reflexed and the punctuation very dense. The punctuation on the face is much finer and wider apart. The prothorax is transverse and very convex; the pro- notum very shining, its punctuation rather fine (the punctures agreeing with those on the face) and remote; the sides are broadly rounded just behind the middle when viewed laterally; the anterior angles are acute but not protruding, the basal ones obtuse ; the middle of the base, just before the scutellum, is faintly raised and projects Notes from the Leyden IVIuseum , Vol. XX. APOGONTA BLANCHARDI, 31 slightly backwards. The scutellum is smooth, impunctate or provided with a few very fine punctures; it has a triangular shape with convex sides. The elytra are strongly punctured, the punctures large but not deep ; provided with three costae, the first slightly broader than the second and third, the narrow interspace outside from the third provided with a row of punctures. The propygidium and pygidiura rugosely punctured, the latter in several of the specimens before me with a raised smooth line along the middle. The sides of the metasternum and of the abdomen are rather remotely punctured. The anterior tibiae are tridentate, the upper tooth is small, often very obscure. Hah, East India: Bengal, Chota Nagpore and Mysore. — (Leyden Museum and Mr. Rene Oberthür's collection). Apogonia impressa, n. sp. A pubescent species which is easily recognizable by the conformation of the scutellum this being broadly and deeply impressed at some distance from the base. Length 10 '/o mm. — Broadly ovate, the thorax con- spicuously narrower than the elytra ; dark brown with a faint greenish and purplish hue, the head and thorax blackish, the antennae and palpi pale ferruginous. Covered with a fine glittering pale ochreous pubescence which is denser set on the elytra than on the head, thorax and underside. The head proportionately small, the face confluently punctured, the punctures forming longitudinal striae sepa- rated from the clypeus by a narrow streak which bears large isolated punctures; the clypeus long, coarsely punct- ured, subtruncate (not emarginate) in front, the margin reflexed. The prothorax conspicuously narrower than the elytra, the sides (when viewed laterally) strongly rounded just behind the middle; the anterior angles acute, almost im- Notes from, tlie Leyden JVLuseum , Vol. XX.. 32 APOGONIA IMPRESSA. perceptibly protruding, their lateral margin narrowly ex- planate; the sides before the obtuse basal angles faintly emarginate; the pronotum is confluently striated in a longitudinal direction, the raised interspaces are smooth and shining, the sulci provided with hair-bearing punctures. The scutellum triangular with rounded tip, broadly and deeply impressed or excavated at some distance from the base, impunctate, the impression however with a few in- distinct longitudinal wrinkles. The elytra at the shoulders conspicuously broader than the base of the thorax, very densely punctured, the punct- ures fine and of equal size all over, the costae only indi- cated by their faint convexity. The punctures on the under surface larger and wider apart, more approximate however on the sides, propygidium and pygidium ; on the latter the punctures are slightly larger than those on the propygidium. The anterior tibiae are tridentate, the upper tooth how- ever is small. Hah. The island of Sumbawa, — The described specimen is in the collection of the Leyden Museum. Leyden Museum, November 1897.

Q. Length 30,5 mm., breadth at the shoulders 10 mm. — Black, covered with a reddish brown pubescence which is very dense round the eyes and forms two slightly diverging vittae on the vertex ; on the prouotum the pubescence forms a broad band along the middle and a narrow stripe on each side ; on the scutellum it is divided along the middle by a smooth stripe ; the elytra are speckled with small spots of a dense reddish brown pubescence and marked, just behind the middle, with a large oblique velvet-black patch which is broader anteriorly than posteriorly and here more approximate to the suture than to the lateral margin ; in front of and behind this black patch the pubescence is of a paler colour and on both sides of the scutellum there is a similarly coloured short, slightly obli- que basal stripe ; the basal joint of the antennae is covered with a thin greyish brown pubescence, the 3rd and follow- ing joints have a dense grey pubescence and are ringed with sooty black on their apical portion. The head shows some punctures on the face, behind the upper lobes of the eyes and on the middle of the vertex; the scape of the antennae is slightly rugose and strongly narrowed towards the base. Notes from, the X^eyden Mluseum, "Vol. XX. 3 34 PELARGODERUS NIGROPLAGIATUS. The prothorax has a small but very distinct tooth on each side; on the bare streaks, especially on their basal portion, very distinct transverse wrinkles are present, and the surface of the thorax is sprinkled with a few black points ; a bare longitudinal line divides partially the median pubescent streak. The elytra have a large depressed space on the middle of their basal fourth ; they are granulate at the base, especially towards and on the shoulder region , and each granule is generally followed by an impressed puncture ; further on the elytra are covered with punctures which become smaller towards the end; the apices are obliquely truncated, the sutural angle is rounded, the outer one distinctly spined. Body beneath and legs sparingly punctured. The inter- coxal part of the mesosternum is slightly raised along the middle and minutely protruding. Hah. The eastern part of the Malay Archipelago, — The Leyden Museum has received the here described female specimen, without indication of a more precise locality, from Dr. H. J. Veth. The distinctly spined outer angles of the apex of the elytra and the ringed antennae together with the large velvet-black patch about the middle of the elytra make this species easily recognizable from the allied P. arouensis Thoms. Leyden Museum, December 1897. P.S. The above description was already printed when Dr. Veth communicated to me a male specimen of this species received by him together with the described female. The male agrees with the female except in the sexual characters, viz. less robust shape, longer antennae, elongate anterior legs etc., but the tooth on the sides of the prothorax, which is very distinct in the female, is almost entirely wanting in the male specimen.

Notes from the Leyden Museum , Vol. XX. JAVANESE BRENTHIDAE. 51 NOTE VIL ON SOME BRENTHIDAE COLLECTED BY M\ J. D. PASTEUR IN JAVA BY Dr. ANGELO SENNA, Assistant in the K. Museum at Florence. Lately I have had the pleasure to receive an interesting collection of Brenthidae from West Java, very kindly offered to me by Mr. J. D. Pasteur to whom I here wish to express my sincere thanks. In the letter accompanying this valuable lot of specimens, Mr. Pasteur gives some remarks on the coloured lines and spots of the elytra in living Brenthidae and says: »Les taches jannes sont toujours d'un jaune tres clair (jaune de paille ou bien de gomme gutte) faisant un vif contraste avec la couleur laque noire des élytres; aussitót que I'in- secte est desséché ces taches jannes deviennent d'une couleur fade , brune claire ou même foncée." In my note : Enumeration of the species known as yet from Java'), treating of Eutrachelus Temmincki Latr., I wrote : »this species varies in having the elytral spots more or less evident", but Mr. Pasteur notices: »Les E. Temmincki Latr. que j'ai collectionnes par vingtaines de toutes dimensions et des deux sexes a Sumatra aussi bien qu'a Java, avaient toujours les taches d'une couleur jaune tres claire de gomme gutte." And indeed, in a few specimens belonging not only to the 1) Notes Leyden Museum, XIV, p. 161, 1892. Notes from the Leyden Musetiin, Vol. XX. 52 JAVANESE BRENTHIDAE. genus Eutrachelus but also to Miolispa , Baryrrliynchus , Orychodes, Pseudorychodes etc. that Mr. Pasteur sent tome preserved in arsenical glycerine , the colour of the elytral lines and spots is very bright and strongly contrasting vrith the dark general tint. In dry specimens preserved in the collections , the differences of colour of the elytral markings are probably due to the different manners of conservation , but I believe also that some species are less subject to this darkening. As I have already worked out in this periodical the Javanese Brenthidae presented by Mr. J. D. Pasteur and other collectors to the Leyden Museum, the greater number of the species contained in the present collection has been previously recorded '), nevertheless I have the satisfaction to find the genera Jonthocerus Lac. and Hi- gonius Lew. not yet collected in Java and some undescribed species. I add also two other genera new to Java, Cy- phagogus Parry and Epicoenoneus Senna, obtained by Mr. Pasteur and presented by him to the collections of the Leyden Museum. Cyphagogus longulus , n. sp. Elongatus, gracilis, niger, sparsim pilosus ; capite elongato, basin versus modice angustato ; metarostro antice vix atte- nuato ; prothoracis lateribus posticis vix recurvis , cono regu- lari, vertice oblique declivi; elytris dorso anguste striatis , striis fere impunctatis , lateribus striato-pimctatis , interstitiis angustis , dorso depressis ; tibiis anticis intus apicem versus curvato-ampliatis , tarsis posticis elongatis , modice robustis. — Long. S'/g mm., latit. max. prothor. 1 mm. 1) These species are the following: Zemioses Icetus Senna, Cerohates tri- striatus (Lund), C. adustus Senna, C. angttstipennis Senna, Trachelizus bisul- catus (Lund), Iliolispa javanica Senna, M. metallica Senna, M. exarafaMe^hr., M. nupta Senna, Prophthalmus longirostris Gylh., P. pugnator Pow., Baryr- rliynchus latirostris Gylh., Orychodes cinnamomi {Hevhst}, Eufrackelus Temmin cki Latr., Schizotrachehis hrevicaudatus Lac, Sch. intermedins Senna, Cediocera tristis Senna and Biurus furcillatus Gylh.

Head elongate, moderately narrower at the base than behind the eyes , convex above , with some hair-bearing punctures scattered at the sides and near the base. Rostrum very slightly longer than the head : metarostrum hardly attenuate anteriorly , prorostrum enlarged towards the tip, scarcely emarginate in the middle, above deplanate, smooth. Antennae compressed, with the joints 3 — 5 almost moni- liform, the ^^'^ — 8*^ broader than long with the sides un- equal in length , the 9th and 10^^ larger, like the preceding ones obliquely cut anteriorly, the apical joint is shorter than the two precediug taken together and acuminate. Prothorax equalling in length the head and rostrum taken together, the sides of the posterior half are slightly curved , those of the cone are regularly oblique, the vertex is subacuminate and obliquely sloping on the apical margin; the prothorax above is scattered with fine punctures bearing long hairs. Elytra elongate, slightly shorter than the head and prothorax together, with the shoulders moderately callous and the sides parallel till the apical third; striate above with the dorsal striae almost impuuctate, the sides are striato-punctate , the interstices broader than the striae, depressed , very obsoletely punctured and hairy. Anterior tibiae with the inner edge enlarged and curved near the apex, penicillate ; hind tarsi elongate, moderately robust and punctured, the metatarsus is slightly shorter than twice the following joint. Metasternum and base of the abdomen convex , almost smooth. C. longulus is the first species of this genus taken in Java ; it belongs to the group of C. Eichhorni Kirsch and C. signipes Lewis from which it is easy to recognize by the characters of the head, prothorax and elytra above indicated. Jonthocerus angulaticeps , n. sp.

Hab. Western Java. cf. Head angulate at the sides behind the eyes, truncate at the base, convex above, channelled ; the portion between the eyes narrow in front; eyes moderate for the genus; metarostrum furrowed, prorostrum distinctly enlarged at the tip. Antennae almost as long as the entire body, slender, delicately hairy, with the joints cylindrical. Prothorax sub-ovate, constricted at the apical margin, convex above , channelled. Elytra elongate, emarginate at the base with the shoul- ders rounded and slightly callous, the sides almost parallel, the tip emarginate in the middle with the external angles margined and almost rounded ; depressed above along the sutural region , striate with the dorsal interstices curved , the 1st (sutural) deplanate , the 2nd interrupted behind the middle , the 3'"^ enlarged near the apex ; sides of the elytra distinctly striate. Legs regular. Body beneath chestnut , shining ; the head and rostrum punctured except on the median line, meta- sternum and base of the abdomen convex, shallowly im- pressed. In the female the head is hardly shorter and broader, the portion between the eyes broader, the eyes smaller, the antennae short and robust, shaped as in some species of Cerobates but with the apical joints slightly longer, the apex of the elytra is margined and rounded, the tarsi are shorter ; beneath the rostrum only is punctured. By the head , angled behind the eyes , J. angulaticeps is allied to J. carinensis Senna but distinguished by the eyes which in the new species are smaller, by the head being chan- nelled and not furrowed, by the prothorax differently co- loured and finally by the elytral apex which is otherwise shaped.

Elytra longer and slightly broader before the middle than the prothorax, the shoulders distinctly angulate, the sides moderately curved, the apex rounded; above with two furrows on each side of the sutural interstice, the remain- ing portion is smooth , shining. Legs as in T. bisulcatus (Lund). Body beneath very shining, the apophysis of the prosternum is broad, the metasternum and the base of the abdomen are slightly furrowed. The female differs by the metarostrum and the apical joint of the antennae which are shorter and by the pro- rostrum which is longer and more slender. This interesting species may be placed near T. bisulcatus by the general shape of the prothorax and elytra, but the rostrum is not enlarged at the tip in the male and the shape of the head recalls the genus Ceocephalus; the cha- racter of the eyes (touching the base of the head) is peculiar to this species.

Of this peculiar and rare species I have hitherto examined a single male, the type, captured by Prof. A. A. W.

Mr. Pasteur has been successful in obtaining of it a female by which I am able to indicate the sexual differences.

Prothorax ovate, narrower anteriorly than behind , with a broad margin at the base, transversely furrowed, convex above, scattered with very fine punctures which bear short hairs. Elytra twice as long as the prothorax and broader than it, the shoulders are rounded, the sides almost parallel in the middle, gradually curved and narrower behind the middle, the tip is almost truncate with the external angles obtusely toothed; above the elytra are strongly punctured and furrowed; some punctures at the sides are hair-bearing but the hairs are shorter than in Ps. piliferus (Senna) ; the 1st furrow is impunctate, the l^t interstice (sutural) is depressed and regular, the 2'^'^ depressed but of irregular width, the following interstices are more raised and convex, broader where they have the yellow-ferruginous lines. The disposition of these lines is the following : the S^d interstice bears two lines in the apical third, the 4*^ has a line near the base, another near the middle and a spot behind it, the 5th has a short line at the base and another be- hind the middle, the 7th a line behind the middle, the Sth a short line at the same position and another longer one on the basal third , where a short line is visible on the 9'h interstice which has also a longer one near the tip. Thighs clubshaped and spiued in the apical third. Body beneath shining, head and metarostrum with a line of punctures beariug hairs and the median interspace raised ; metasternum foveolate at the apex , the base of the abdomen is convex. Of this handsome species, Mr. Pasteur sent me a single female. The male has certainly a slender rostrum, the eyes more prominent, the prothorax more attenuate near the apex and broader behind the middle. Ps. dentipennis is easily distinguishable from all the species which have likewise a slender rostrum, by the obtusely toothed external apical angles of the elytra and by the 2^'! interstice being depressed in the median portion.

In the male the pro- rostrum is longer, much curved, slightly enlarged from its rise till the tip ; in the female on the contrary the prorostrum is shorter, more curved , and more rapidly and conspicuously enlarged at the tip.

Belongs to the group of M. pygmaea Senna and M. sycophanta Senna (though the head is nearly square) and is allied to M. lineata Senna from Java, of which the present is certainly the representative at Borneo. 1 have distinguished it in consideration of the following characters taken after a careful examination of two specimens (males) equal in size. In M. borneensis the head is slightly shorter with the vertex not channelled; the median joints of the antennae, especially the 7^^ and 8^^ , have the sides ZVotes from the Leyden Museum, Vol. XX.

Notes frora the Leyden IMuseum, Vol. XX. 72 PSEUDORYCnODES CRUENTATUS. Belongs to the group of Pseudory diodes which has a slen- der rostrum ; the species of this group may be divisable according to the shape of the elytra at the tip. The new species has the elytra rounded and emarginate in the middle at the apex and consequently must be placed near Ps. insignis Lewis from which it differs by the smaller head, by the shorter rostrum, by the elytral furrows being narrower and shallowly punctured and finally by the different dis- position of the elytral lines which are also more numerous. Any confusion of this new species with the others of the same group is not possible, and indeed from Ps. Fruhstor- feri Senna it is recognizable by the head which is smooth above, from Ps. piliferus (Senna) by the elytra which are bare, without hairs, and from Ps. Ritsemae (Senna) by the rostrum , prothorax and antennal joints which are shorter and otherwise shaped. Schizotrachelus interruptus , n. sp. cf.

The wing is round ; the primaries nearly hidden under the long and soft coverts; the first primary is 40 mm. long and 15 mm. shorter than the S^d and 4*^, which are the longest, though only a little longer than the 2°^ and 5th; the exact number of primaries is difficult to ascertain with- out injuring the specimen. For the same reason I am able to find only two tailfeathers (dark coloured, soft, narrow and 20 mm. long), as they are hidden under the extremely thick , long and soft upper tail-coverts and are difficult to distinguish from the latter. So this species may be called „ecaudatus'^ as truly as Pennula ecaudata (King) , and , as seen by the structure of the wings , is no doubt a flightless form. The feet are feeble; the nails short and small. The type specimen in the Leyden Museum is stuffed and not too well ; the stuffing , however, is apparently not of very old date , as may be judged from the artificial eyes (with red irides), which seem to be of enemelled glass, or — at any rate — of a kind, which was unknown in the beginning of this century. The wire used for stuffing is of brass, as commonly used by the taxidermists of the Leyden Museum.

WlLSONl. 79 » observe dans les iles Sandwich; voyage de Cook", but this statement does not seem to rest on any reliable foundation , for there does not exist any notice when and from wJiom Temminck acquired the specimen! This fact must be men- tioned , as Dr. Hartlaub assures us that Temminck bought this Rail at the auction of Bullock's collection (3 June 1819) for £ 1.10, which may have been the case; but it cannot be proved that it was the specimen in question. That it was not brought home by Cook from the Sand- wich Islands is without the slightest doubt, for, according to the researches of Prof. Newton, Cook's specimens were not skins but dried examples and have long since perished. Besides this, Latham described his » Sandwich Rail" from the collection of Sir Joseph Banks; so his type cannot be the same as the specimen in the Leyden Museum. Latham's » Dusky Rail" {Rallus obscurus Gm\.), said to come also from the Sandwich Islands, is, according to his descrip- tion, a quite different and much larger bird («legs two inches" = 50 mm.; »legs red brown"; »bill scarcely one inch" — our specimen has the bill only 7^ ƒ2 lines long!), and is most likely not a „Pennuhi' at all. Evidently Latham would have mentioned the rudimentary tail ^), as he did not over- look this prominent character iu the description of his » Sandwich Rail". The type of Latham's » Dusky Rail" was in the Leverian Museum , but unfortunately appears to have been also lost. Schlegel's »Crex sandwichensis'^ is only known from the specimen in the Leyden Museum and is no doubt one of the rarest of birds , being most certainly not the same as ■» Rallus sandioichensis''' or ■» Rallus obscurus'^ of Gmelin; it must therefore be renamed. I have the pleasure to name it after Mr. Scott B.

Ley den Museum, February 1898. Notes from tbe Leyden. IMiisevim, Vol. X. ON PSOPHIA VIRIDIS AND PS. OBSCURA. 81 NOTE XL ON PSOPHIA VIRIDIS AND PS. OBSCURA BY Dr. O. FINSCH. When Dr. Sharpe wrote the Catalogue of the Fulicariae and Alectorides (Birds, vol. XXIII, 1894) he referred with regard to the above two species to the material in the Leyden Museum , as they were not then represented in the collection of the British Museum. Misled by the wrong determination of the specimen labelled »Psophia viridis Spix" Dr. Sharpe declared both species named above iden- tical, saying, and no doubt quite correctly, in reference to the two specimens in our Museum »I have seen one of the typical specimens of Psophia obscura in the Leyden Museum and could not find any character distinguishing it from Ps. viridis". But the specimen out of the old collection of Temminck and labelled in his handwriting » Psophia viridis Spix , Bolivia" does not belong to this species , but is a true Ps. obscura Natt., of which species our Museum fortunately possesses one of the 3 examples collected by Johan Natterer at Para. This specimen , an old female , is the type of Sharpe's description of his »Ps. viridis" and differs from the other one {»Ps. viridis Temm. nee Spix) in having purple tips to the greater series of the wing coverts. Otherwise both specimens are exactly alike; the feathers of the neck are almost black like the under parts, and show only a faint purplish gloss, but by IS'otes £roca. the X^eydeu ]\Xu.seu.m, "Vol. X.X.. 6 82 ON PSOPIITA VIRimS AND PS.

Bras. 11, 1825, p. 66, tab. 83), of which we possess no specimen, is, judging from descriptions , an allied but decidedly distinct species. W. Blasius ') in his review of the species of this genus says: »die Federn des ünterhalses stark metallisch kupferfarbig und hauptsachlich violettglanzend" which is not the case in Ps. obscura. And besides »der Rücken, die verlangerten weichen Schulterfedern grün , rait llostfarbe vermischt", it does also not answer to our specimen of Ps. obscura , which has the feathers of these parts (the back and shoul- ders) only margined with green , and therefore only shining with green in certain lights. 1 append a list of the species of the genus Psophia in the collection of the Leyden Museum: 1) Psophia crepitans L.

In Vol. XVIII, pag. 135, of this periodical I have des- cribed a uew Melania with the specific name Junghuhni. Now some time ago Prof. K. Martin directed my attention to the fact, that this name was preoccupied for a fossil species, described in 1879/80 in his work: Die Tertiar- schichten auf Java; Palaeontologischer Theil, pag. 89, pi. XIV, fig. 20. So his name has the priority, and my spe- cies must receive another name , for which I propose Melania Martini., after the person who has detected the error. I may make the apology, that, as it is already not an easy matter to avoid such errors with the names of recent spe- cies, it becomes very difificult, to know also the names of the numerous fossils. Fupina sucinacia Boettger. In studying some specimens of Pupina from Java , I got for comparison the types of Pupina Junghuhni (Herklots ms.) from the Leyden Museum , described by Prof, von Martens , in : Die Preussische Expedition uach Ost-Asieu ; Zool. Theil , 1867, pag. 156, and was struck with the extreme resem- blance of this species to P. sucinacia Boettger, described ;Notes from the Leyden IVIuseuin, "Vol. XX. CONCHOLOGICAL CORHECTIONS AND ADDITIONS. S5 in : Bericht über die Senckenbergische naturf. Gesellscbaft in Frankfurt a/M., 1890, pag. 157, especially with the variety bearing the manuscript name porcellanea; indeed I could not detect a single character that might have specific value. The Museum specimens are partly deprived of the enamel , but this is only individual , probably they were not col- lected alive, as the operculum is wanting. Prof. Boettger, having seen a typical specimen, fully agrees with my opinion and so P. sucinacia falls in synonymy, since the name Junghulini has the priority for twenty three years. I think this error may be accounted for, by the different method of measuring; von Martens says: «Long. 11, diam. maj. 9, min. 5~/.j ; apert. alt. 6, lat. 5 Mill.» and Boettger: «Alt. 9 — 9'/2, diam. max. 6'/2 — 7, apert, intus 3^4 mni. alta, 3 lata.» Now the largest specimen in the Leyden Museum has from the apex to the base of the peristome only lO'/j mill, long.; so «Long. 11» by von Martens is probably a typographical error for 10, the other specimen measures scarcely 10 mill.; these measurements are taken diagonally; if taken perpendicularly they are still smaller. The diam. maj. of 9 mill. , is even scarcely reached if one takes the utmost breadth in an oblique direction ; if measured horizontally without the peristome it is a trifle more than 7 mill. Von Martens has measured the aperture with the peristome in its largest extension, Boettger without the peristome. It is a new proof how desirable it is to have a uniform method for measuring shells. Cyclotus dimidiatus Kobelt. A few months ago I had to study some shells from Celebes, belonging to the Leyden Museum, amongst which I found a Cyclotus which I suggested to be C. dimidiatus Kobelt, described in: Abhaudlungen und Berichte des Königl. Zool. und Anthropol. Ethnogr. Museums zu Dresden, 1896/97, N° 5, under the title »Schnecken von N. O. Notes from, the Leyden INluseum , Vol. XX. 86 CONCHOLOGICAL CORRECTIONS AND ADDITIONS. Celebes u. Banggai." The shell agreed in every respect, but as I fonud that it had the rapidly increasing upper whorls radiately and concentrically striated , the last whorl being comparatively smooth , and that the peristome was orange yellow , which important characters wanted in the description, I asked Dr. Kobelt to inform me if his shell possesses the same characters. Dr. Kobelt wrote that the specimen was returned to Dr. A. B. Meyer, Director of the Dresden Museum, who on his turn told me, it was sent for comparison to the brethern P. and F. Sarasin in Basle, who wrote in reply on my request, that the speci- mens have: »eiuen hell orange rothen Mundsaum und dass sie die erwahnte Gittersculptur auf den oberen Windungen aufs deutlichste zeigen." Thus I found my determination to be right. I thought it might be useful to publish these facts, as especially the sculpture of the upper whorls may greatly tend to recognize the species , for 1 cannot find a similar structure in any of the other species of Cyclotus from Celebes.

The scutellum is broadly rounded at the tip. The sides of the elytra are nearly parallel, the shoul- ders armed with a pointed granule, the apices obliquely truncate and armed at the sutural as well as at the outer angle with a sharp spine. The basal fifth of the elytra is is covered with large shining black granules which are somewhat smaller and more densely set on the sides where they extend moreover further backward, almost down to the first naked band.

Apriona buruensis , n. sp. cf. Length 52 mm., breadth at the shoulders 18 mm. — Black, the elytra dark brown; covered with a delicate greyish brown pubescence which is denser on the sides of the metasternum and of the abdomen where it forms an indistinct dirty white vitta. The antennae are rather slender, distinctly longer than the body and entirely sooty black, not ringed with grey. Irapunctate. The scape of the antennae slightly scabrous towards the top on the outside. The disc of the pronotum with very few transverse wrinkles, the lateral spines acute and straight. The scutellum broadly truncate posteriorly. The base of the elytra is provided, solely on the shoulder region , with some shining black granules ; the shoulders are armed with a distinct tooth; the apices are obliquely truncate, their outer angle is rounded, the sutural one provided with a short spine. The above described male specimen , originating from the island of Burn (Dr. Bernstein), was regarded by the late Dr. Snellen van Vollenhoven as belonging to Apriona humeralis Kaup , but , according to Mr. Neervoort van de Poll who has seen Prof. Kaup's types in the Museum at Darmstadt , the last quoted species does not belong to the genus Apriona but is synonymous with Jothocera tomen- tosa (Buq.).

Shell somewhat squarely oblong, moderately inflated, very inaequilateral , covered with a dark-brown fibrous epidermis, giving to the shell the appearance of being concentrically striated; striae coarser towards the margins, if seen by transparent light the colour is yellowish-brown. The um- bones being decorticated , no sculpture is perceptible on these parts, but the posterior slope is provided with radia- ting folds, usually becoming bifurcate towards the margin. Upper margin moderately curved, anterior margin rounded, passing insensibly into the rather straight ventral margin ; posterior margin sinuous above, then abruptly truncate, forming two angles, one at the upper part of the trunca- tion and one at the beginning of the ventral margin; from this point an obtuse ridge runs towards the umbones. Nacre iridescent, bluish white near the margins , olive yellow near the umbones. Hinge strong, one thick tooth in the right valve , with crenated edge , two in the left valve , the posterior one being the largest; both are obsoletely crenated. One lamella in the right valve, two in the left one, they are slightly curved, somewhat crenated posteriorly. An- terior scars irregular, deep, posterior ones shallow, pallial line distinct. A flat callosity runs from the umbones, obli- quely towards the ventral margin. Long. 69, alt. near the umbones 37, at the angle of superior and posterior margin 40, diam. 19 mill.

I have named the species in honour of its discoverer. Rhoon near Rotterdam, March 1898. Notes from the Leyden. ]Museum , Vol. XX. ON MUSCICAPULA WESTEUMANNI AND M. MELANOLEUCA. 93 NOTE XVI. ON ïtlE IDENTITY OF MUSCICAPULA WESTER- MANNI, SHARPE AND M. MELANOLEUCA, HODGS. BT Dr. O. PINSCH. Under the first name Dr. Sharpe describes (Proc. Z. S. L. 1888, p. 270) a small flycatcher, a single specimen col- lected by Mr. L. Wray in the principal mountain range of Perak (Mt. Ulu Batang Padang, 4200 f. h.). This spe- cimen was marked » adult male", but Mr. Sharpe adds:» it may not be the fully adult of its species, but I believe it to be so" and remarks further: »the reddish upper tail- coverts and tail remind one of the female of M. maculata^ but the blue-grey upper surface distinguishes it at a glance." The relationship is here correctly pointed out, for the type- specimen of M. Westermanni is undoubtedly not an » adult male" but an » adult female", as proved by Dr. Sharpe himself on a pair of flycatchers collected by Mr. White- head on the Kina Balu. About these two birds Dr. Sharpe says (Ibis 1888, p. 885): »I cannot see any difference between this male bird and specimens from the Himalayas {M. maculata Tick.). The bird Mr. Whitehead sends as the female is undoubtedly the same as my M. Westermanni, so that if those two birds are sexes of one species, the latter may have to be separated on the females alone, while M. Westermanni (» female"!) is certainly different from any Himalayan specimen of M. maculata^ Notes from. th.e Leyden JVCuseum, Vol. XX. 94 ÜN MUSCICAPULA WESTERMANNI AND M. MELANOLEUCA. Species in which the males are precisely alike and which can be only distinguished by differences in the colours of the female, may always be considered as rather doubtful, and this as more if these differences are so slight as between the females of M. melanoleuca and of the so- called M. Westermanni. The more grey tone on the back of the latter, scarcely to be termed » blue-grey", is seen in freshly moulted females, as in the specimen (N'^ 14) in our Museum from the highlands of Luzon. Other females from Java (N" 8), already specifically separated by Tem- minck s. n. Muscicapa Hasselti, and from Timor, show the upper surface more brownish grey and agree perfectly with Dr. Sharpe's description of the female oi M. maculata from Sikkim (Cat. B. Brit. M. IV, p. 207). As in many other similarly coloured species the colouring of the back varies therefore somewhat. So Mr. Oates notices: » females from Mauipur are commonly much darker than such from the Indian peninsula", and Mr. Grant likewise says (Ibis 1896, p. 540): » upper parts of females from Negros are of a rather darker grey than in Luzon specimens." The male birds show also certain variations after age and season, chiefly in the extension of the white parts; the white longitudinal stripe above the eyes is more or less developed, as this is the case with the white basal portion of the tailfeathers, and the white longitudinal mark on the wings. The freshly moulted male (N" 10 from Timor) has the whole outerweb of the last secon- daries white, whereas other males show only a more or less broad white external margin on these feathers. I may add that the male assumes his full dress immediately from the first plumage, as clearly proved by specimen N°^- 9 and 7 (from Java) in our Museum. The example N^ 9 is a nestling in the first plumage, spotted like in our Musci- capa grisola; no white superciliar stripe; the white on the wings is nearly developed and the freshly grown tail- feathers are already precisely agreeing with these in the old male. The specimen N^ 7 is of more advanced age Notes from tlie Leyden >luseu.m. Vol. JX.X. ON MUSCICAPULA WESTERMANNI AND M. MELANOLEUCA. 95 and shows nearly the same black and white garb as the old male, only mixed on the upper surface with a few mottled feathers of the nestling dress. In the synonymy I follow Oates adopting the specific name » melanoleuca Hodgs." (1849), an unpublished name also bestowed by Temminck to the same species, as Ti- ckel's older appellation •»maculata' (1833) was published without a description. According to Oates » Erythrosterna pusilla Bl." is only the female of this species, and Dr. Sharpe gives also Muscicapa pooensis BL, Muscicapula acornaus Bl. and M. leucoschistos Bl. as synonyms. Accord- ing to a note by Blyth (Ibis 1866, p. 372) this last spe- cies seems however a quite different bird and nearly allied to Muscicapula superciliaris. Muscicapula melanoleuca Hodgs. Bl. Journ.

The specimens N° 5, 6, 7, 9, 10 and 11 were labelled by Temminck himself »Muscicapa melanoleuca, n. sp.", N^ 8 »Muscicapa Hasselti, n. sp." but not published; the specimens N° 12, 13 and 14 were received s. n. »M. Wes- termanni". Specimen N" 12, collected by Mr. Everett and marked » female", is no doubt an »old male" in freshly moulted dress, some of the wing- and tail-feathers are not yet full grown (shot in October). Muscicapula melanoleuca is a mountain bird, breeding in high altitudes, as shown by the references given before in the synonymy, and visits low land only during the cold season.

ON THE SPECIFIC DISTINCTION OF THE GROUND- CUCKOOS OF BORNKO AND SUMATRA (CaRPOCOCCYX RADIATUÖ AND C. VIRIDIS) BY Dr. O. PINSCH. Among the birds collected by the French naturalist Mr. P. Diard , who in the service of the government of Dutch India in 1826 first explored the district of Pontiauak , west-coast of Borneo, the most interesting is no doubt a Ground-Cuckoo , peculiar by its large size and vivid colours. Diard got only one specimen , which reached Leyden not before 1828 and which was described and figured by Tem- minck in his » Planches coloriees" (91e Livr., 1832, PI. 538) under the name » Calohates radiceus'\ afterwards changed in » Calohates radiatus" (Tabl. méth. or Index to the above work, p. 53, 1838). I mention these dates only to show that publication in those days did not go on so quickly as at present. This type-specimen of the PI. col. is »La femelle adulte", and Temminck anxiously waited , but in vain, for the »male", said to be, according to Diard, more vivid in colours and with a tail » double plus longue" (!) No other explorer of that period mentioned this sing- ular bird with the exception of Dr. Salomon Muller , who, however, gives only the name {Calohates radiatus^ in » Ver- handl. over de Natuurl. Gesch., Land- en Volkenk., etc. (1839—44) p. 234, Note) with » Borneo and Sumatra." Strange enough he does not mention having got the bird Notes frora thie Leyden ÜVIuseuixi, Vol. XX. 7 98 ON CARPÜCOCCYX RADIATUS AND C. VIRIDIS. himself during his explorations in Western Sumatra (1833 — 36), although there is one specimen in the Leyden Mu- seum labelled » Sumatra, voyage Salomon Muller." Pro- fessor Schlegel in his Catalogue of the Ouculi (Mus. Pays- Bas , 1864, p. 60), apparently misled by the duller colours, enumerates this specimen as the »fem. adulte" of the bright coloured Bornean-specimen , which latter he labels » male adulte." The specific identity of the large Ground-Cuckoos of Borneo and Sumatra was thus confirmed , although the measurements given by Schlegel show such unusual difie- rences in size that one might feel inclined to base upon specific value. But Schlegel does not say that there are also conspicuous differences in coloration , and it was not before many years afterwards that Count Salvadori, who got three specimens collected by Odoardo Beccari on Mount Singalaug, west-coast of Sumatra, pointed out the specific differences and, although hesitatingly, proposed a new name (C. viridis) for the Sumatran bird. And this is in- deed an excellent species, as will be seen by the following characters taken from specimens in the Leyden Museum , which possesses an interesting material on these birds , still very rare in collections. In the British Museum , for example, C. viridis is wanting. Carpococcyx radiatus (Temm.). Calobates radiceus Temm. PI. col. 538 (91e Livraison, 1832). C. radiatus Temm. Tabl. méth.

Larger; shoulders, secondaries and tail purplish- violet, with coppery-red reflections; head, nape, sides of head, chin and throat black, shining with violet on the vertex and nape. Notes from the Leyden IVIiiseum , Vol. XX. ON CARPOCOCCYX RADIATUS AND C. VIRIDIS. 99 Moreover in this species the back and wing-coverts are of a vivid green , the sides of the neck and the crop grey. Besides the old female (Cat. N\ 1) figured in the PL col., from Poatianak (Coll. Diard 1826), the Leyden Mu- seum possesses another old female (Oat. N°. 3) collected by Dr. Nieuwenhuis on the Loug-Bloe , a branch of the upper Mahakkam , Central-Borneo (October 1896), and an old male (Cat. N°. 2), collected by Mr. Hose in the in- terior of Sarawak and presented by him to the Museum. The female N°. 3 shows faint dark green apical margins on the feathers of the rump , and therefore this part is not so distinctly barred with dark ; but both sexes are precisely alike , in size as well as in colours. »Irides grey, with a narrow brown outer circle; bill, feet and the naked space round the eye oilgreen" : Dr. Nieuwenhuis. Diard describes the naked part round the eye as »red" and accordingly this colour is used also in the PI. col. and our type to it. Mr. Hose got this fine Cuckoo in the interior of Sarawak (Mt. Dulit, Baram district and Kalulong) and gives only the following short notice: »a very rare bird, only found on the ground. Native name »Kruai Manang" (Ibis, 1893, p. 415)." Dr. Nieuwenhuis remarks only: » contents of stomach remains of beetles and other insects; native name »Manok bawai" (M.S.). Carpococcyx viridis Salvad. et C. radiatus (Temm.)? in: Annali del Mus. Civ. di St. nat. di Genova, vol. XIV (1879), p. 187. Neomorphus radiatus Schleg. (nee Temm.), Mus. P. B. Cuculi (1864), p. 60 (N°. 2 >femelle"). C. viridis Shelley, Cat. B. Brit. Mus. XIX, p. 415. Smaller; shoulders, secondaries and tail dark green, without any purplish or coppery reflections; top of the head black (without violet shine) ; nape dark green ; the chin black as also a longitudinal stripe margining the naked space round the eye from below. Notes from the Leyden IMuseuiri , Vol. X.X.. 100 ON CARPOCOCCYX RADIATUS AND C. VIRIDIS. Besides that in this species the throat and sides of the neck are greenish-grey , the back and wing-coverts are darker green than in C. radiatus ; the dark crosslines on the ab- domen are narrower and stand more closely , the sides of the breast and vent are washed pale rufescent, which co- lour is very distinct on the black barred lower tail-coverts. The Leyden Museum possesses two specimens : one (Cat. N°. 1) collected by Dr. Salomon Muller in western Su- matra (Padang), the other (Cat. N°. 2) by Mr. van Has' selt (1880) in the same district; this last specimen is af- terwards signed by Schlegel's handwriting » Neomorphus radiatus sumatranus" . None of the specimens are sexed , but we may trust that in this species too both sexes are alike. The specimen N°. 2 shows remains of the first plumage: on the head there are a few rufous-brown feathers and among the not yet full grown primaries is an old one: brownish-black, narrowly margined with rufous-brown on the outer web. Salvadori describes the young bird as blackish , with chestnut-brown crossbands ; occiput blackish, quills greenish- black , margined with rufous. The naked space round the eye is: »di vari colori; verde, blue, e rosso-vinato chiaro." Judging from our skins the naked space round the eye , and the bill and feet are green. Of the habits of this species nothing is known. Al. caud. culm. tars. 256 mm. 306 mm. 49 mm. 97 mm. radiatus NO. 1 ?. (French) 9,04 inck. 11,2 inch. — 3,6 inch.

A. JENTINK. June 1898. The other day I read in a dutch popular periodical a paper dealing with the different species of Bears aud their geographical distribution. To my great surprise the Ma- layan Bear was uaentioned from Java : the locality Java being quite new to me I wrote to the author of that paper and asked him some informations about the matter: he referred me to Brehm's »Tierleben" and Flower and Ly- dekker's » Mammals." Indeed on p. 245 of Brehm's Tierleben , Saugethiere , zweiter Band, 1890, Dr. Pechuel Loesche stated: »der Biruang [Ursus malayamis) bewohnt Borneo, Java, Suma- tra, die Malayische Halbinsel und verbreitet sich nordwai'ts durch Tenasserim bis nach Burma und durch Arakan bis nach Tschittagong" ; and in Flower and Lydekker's Mam- mals, 1891, p. 559, the geographical distribution of the Malay Bear or Sun Bear [Ursus malayanus) runs as fol- lows: »this small species inhabits the Malay Peninsula, Sumatra , Java , Borneo , Tenasserim , Arakan , Chittagong and the Garo hills of India." Scrutinizing what has been published concerning the geographical distribution of the Malay Bear I see that there are more authors who believe that in the island of Java is living a Bear. I only have to remember the opi- nion of the following authors. Notes from the Leyden M.u.seuin , Vol. XX.. 110 WHAT ABOUT THE JAVAN BEAR? 1829. J. B. Fischer.

As the description of V. Wurmb's otter as well as Illiger's name for that animal are to be found in rather unknown or difficultly accessible books, it may perhaps bear some interest to give the full and exact titles of the mentioned books , the more as Thomas himself is not quite correct in his quotation and as Blanford in his » Fauna of British India, Mammalia, 1888 — 91" though accepting Thomas' interpretation commits an- other error (Illiger 1815 instead of llliger 1811).

Dr. Nieuwenhuis relates that the animal is living along the upper and middle Mahakkam, Batang, Badjang and Upper Silat. It frequents in small troops principally young bush and shrubs; the Baham-men hunt it very seldom as they do not like its flesh as a meat ; the Malay however are more fond of it. The indigenous men (so Dr. Nieuwenhuis reported) dis- tinguish two varieties : a large black one and a smaller red form. The photo (plate 2) and the skull belong to spe- cimens of the black variety. It is well known that the adult female is more reddish , not so dark colored as the adult male. According to Dr. S. Muller the Dajaks along the Doeson-river call the (black-colored) adult animal Roempoe and the (red-colored) calf Banteng — and by that way I explain Dr. Nieuwenhuis' black and red varieties.

In the beginning of this year our herpetological collec- tion was enriched with a specimen of the gigantic land- tortoises from the Galapagos-islands. The specimen, a male one, directly struck me by the peculiar arrangement of the pectoral shields , which have a triangular form , and do not meet in the middle of the plastron. On further information as to the exact locality where our tortoise was captured , I learned from Prof. Giglioli , to whom the specimen had formerly belonged, that it was captured by the captain of an Italian merchant-vessel in 1884 on the island of Duncan, together with a similar but smaller male specimen, which was still in the Florence Museum. Now the peculiar arrangement of the pectoral shields of our specimen quite agrees with the form and position of these shields in Testudo emys and in Tesfudo Phayrii; the former species showing the said arrangement with both sexes, the latter only with the males ^). For this reason I thought it probable that our specimen, together with the Florence 1) See my note on Testudo emys and its affinities. Notes Leyden Museum , Vol. XVII, p. 197.

I therefore had the lower part of our specimen photographed , and sent a photograph to Prof. Giglioli , asking him to be so kind as to compare my photograph with his specimen and to give me information as to the pectoral shields. Prof. Giglioli very graciously answered my letter expressing his regret that he was unable to give me the information I had asked for, as the smaller speci- men was sent in communication to the Hon. Walter Roth- schild. Accordingly, I addressed myself to the well-known proprietor of Tring Museum , explaining my case to him , and asking for information about the smaller Duncan- specimen. The Hon. Walter Rothschild, whose interesting contributions to zoology are valued by all zoologists, not only gave me the particulars I had asked for, but with extreme kindness and great liberality gave me all infor- mation he could furnish to help me to decide this diffi- cult question. He expressed as his opinion that the tor- toises of Duncan-island all belong to one and the same species viz. Testudo ephippium Gthr., the specimens varying much at different ages. His opinion is based on the com- parison of 31 living and dead specimens of different sizes, obtained from that island and now in his collection , and of 5 other specimens including the type, which is in the Edinburg Museum. To enable me to judge myself, he very graciously sent me for comparison 2 specimens of P. ephippium: one skeleton measuring 62 cm. over the curve, and a very large unmounted specimen measuring 83 cm. Moreover he sent me : 1". an outline sketch of the front part of the plastron of Prof. Giglioli's specimen, which shows the pectorals meeting one another in the middle of the plastron. 2**. an outline sketch of the front part of the plastron of a large male, weighing 180 kilogram, and showing the right pectoral shield normally developed, while the left has its middle part reaching its fellow , but atrophied to half its proper size. Notes from the Leyden JMiiseuiii , Vol. 'X.X., 128 ON TliSTUDO EPHIPPIUM. In view of all these evidences , and as our specimen in all essential points , the pectorals excepted , resembles the specimens of' Testudo ephippium , I feel inclined to regard the peculiar arrangement of the pectorals in our tortoise as an individual abnormity. However , with regard to the normal occurrence of this special arrangement of the pectoral shields in Testudo emys and Testudo Phayrii^ I think the individual abnormity of our specimen of Testudo ephippium so remarkable, that I think it worth while to publish the figures together with the measurements of the different shields of the plastron.

After a careful comparison the specimen proves to belong to a new species, nearly allied to G. inomata Wall, and G. Everetti Hartert, but easily to be distinguished by the markings of the tailfeathers, which show only a pale whitish marginal spot before the end of the inner web (faintest on the outermost feather) and no broad distinct white end (tipped with smoky) and running over both webs on the two outermost as in the above mentioned species. The bill is as large as in G. Evei^etti, and the legs are even somewhat longer than in this species. The Leyden Museum possesses 4 specimens of G. inor- nata Wall. (Proc. Z. S.

It appears to me, however, probable that other species which occur exclusively in fresh water, are distributed over a small area , inhabiting e. g. one single large river with its tributaries. To the latter seems to belong Pal. sintangensis , the specimens of which have been collected by the Expedition in the interior of Borneo at Sintang. Pal. sintangensis is apparently a species of small size, the largest specimen, a male, being only 57 mm. long from the apex of the rostrum to the tip of the telson. It bears a considerable resemblance to Pal. (Eupal.) Ritsemae de M. from Atjeh , exhibiting indeed almost the same cha- racters, but it differs at first sight by the size of the eggs. An ova-bearing female and a younger one of Pal. Ritsemae, original type-specimens from the collection made by capt. Storm, are lying before me: the eggs are very numerous and small, being only 0,6 mm. long and 0,5 mm. broad. The two females of Pal. sintangensis , however , carry a much smaller number of eggs and these eggs are more than twice as long and more than twice as broad as those of the Atjeh species: they are 1,6 mm. long and 1,2 mm. broad. The ensiform rostrum has nearly the same form as that of Pal. Ritsemae and reaches to the end of the antennal scales, in young individuals it extends sometimes even slightly beyond them. The upper margin is usually slightly convex above the eyes and the apex mostly a little turned upwards ; in a very young male specimen even almost the whole rostrum is slightly upturned and tapers more than usually towards the apex (Fig. Id). On the upper margin 12 or 13 teeth are observed, rarely 9 or 10; the first tooth is commonly separated from the second by an interval twice as large as between the following, which above the eyes are equidistant and mostly placed close Notes from th.e Leyclen IMuseum, Vol. XX- 140 CRUSTACEANS OF THE together (Fig. la); towards the apex the intervals become again larger. Usually the first three teeth are placed on the cephalothorax , the fourth immediately before its anterior margin ; sometimes only two are placed on the carapace and then the third tooth stands above or just before the anterior margin. The lower margin is armed with 4 or 5 teeth. The cephalothorax of the adult male appears slightly scabriculate anteriorly , especially towards the inferior lateral margins, when seen under a strong magnifying glass, but that of the female and younger specimens is smooth. The telson fully agrees with that of Pal. Ritsemae and of most other species of the genus: it terminates into an acute point, that reaches slightly farther than the external subterminal spinules. The external maxillipedes exceed the antennal peduncles by the larger part of their terminal joint. The first pair of legs exceed the antennal scales by their chelae and their merus reaches the distal end of the antennal peduncle; the carpus is slightly more than twice as long as the hand, the former measuring T'/g mm. in the adult male, the latter 8' ,'4 mm. The second pair of legs of the adult male are of equal size and length, and just as long as the body; their joints are cylindi*ical , so that this species belongs to the subgenus Eupalaemon. The merus measures one fifth of the length of the whole leg and extends to the tip of the antennal scales. The carpus and the hand appear at first sight equally long, but, when accurately measured, the hand of both legs proves to be very slightly longer than the carpus (confer the measurements). The slender carpus, once and a half as long as the merus, presents nearly the same breadth until the middle of its length , but then gradually grows thicker until its distal end and here its diameter measures '/o — ^lo ^^ ^^^ whole length. The palm , nearly as long as the merus , is cylindrical , being about as broad as thick , and justly as broad as Notes from the Leyden Museum, Vol. X.X.. DUTCH BORNEO-EXPEDITION. 141 the distal extremity of the carpus. The fingers are four fifth or three fourth of the length of the palm and meet along their inner edges when closed. The dactylus , examined with a lens , presents two small teeth near the articulation, the first of which appears double , the second conical ; the immobile finger is also armed with a small conical tooth , placed between the two opposite teeth of the dactylus. Like in the other allied species on each finger a sharp cutting-edge runs between the second tooth and the tip. These legs are covered with minute points , those on the inner margin of the joints are a little larger , appearing here as sharp thorny spinules , directed forewards ; the fingers are nearly smooth. The latter are covered with rather close hairs on each side of the basal teeth and of their cutting- edge , until slightly beyond the middle of their length ; for the rest the second pair of legs are glabrous. The second pair of legs of a younger male, which is 47 mm. long , are comparatively a little shorter , measuring two thirds the length of the body : they are also less stout and thinner than the described legs of the adult male. The merus does not reach the tip of the antennal scales, so that only three fifth of the carpus project beyond it; it measures also ^j- the length of the whole leg. The carpus, again nearly once and a half as long as the merus, is almost as long as the hand, not shorter as is the case in the adult male. Its diameter at the distal end measures scarcely ^/u of its length. The fingers have exactly the same length as the palm and are not yet covered with hairs , but the teeth are already developed (Fig. Ig). Finally, the second pair of legs of a quite young male which measures only 33 mm., are but half as long as the body. The merus projects scarcely beyond the antenoal peduncle and measures again one fifth of the whole leg. The carpus is only a third longer than the preceding joint and, accu- rately measured, proves to be slightly longer than the hand, as in Pal. Ritsemae', its diameter at the distal Notes from ttie Leyden Museum, Vol. XX. 142 CRUSTACEANS OF THE extremity measures '/jg of its length. The fingers are a little longer than the palm, still glabrous and the basal teeth are scarcely visible. The larger ova-bearing female has about the same length as the adult male and is still provided with the right leg of the second pair. This leg measures about two thirds the whole length and is thus shorter and less stout than the legs of the adult male. The merus reaches the distal end of the antennular peduncle, as far as in the male of 47 mm. The carpus, once and a half as long as the merus, is still slightly more slender than in the male, its diameter at the distal extremity measuring only '/jj of its length, though the form is quite the same. The hand is di- stinctly shorter than the carpus, measuring four fifth of the latter, and the fingers are somewhat shorter than the palm, in the same proportion as in the adult male. Examined with a lens, the fingers present the same minute basal teeth (Fig, li) and the same cutting-edge as in the male, but they are not covered with hairs. The minute points and spinules on the surface of the joints are scarcely visible and the leg appears smooth for the naked eye. The other ova-bearing female, that has also lost one of the legs of the second pair, agrees fully with the other. In a still younger female, 38 mm. long, the carpus appears also distinctly longer than the hand. We may conclude from the preceding description 1° that the carpus of very young male individuals is a little longer than the hand, that both joints have the same length in middle-sized male specimens, but that the chela of the adult male is slightly longer than the carpus, 2° that the carpus of the female is constantly slightly longer than the hand, and finally that in adult specimens the carpus is once and a half as long as the merus, in younger indivi- duals once and a third. Notes from the Leyden Museum, Vol. XX. DUTCH BORNEO-EXPEDITION. 143 The ambulatory legs are as thin and slender as those of Pal. Ritsemae^ but the terminal joints are a little longer, measuring nearly one third ofthe pro- podi, those of Pal. Ritsemae only one fourth. In the adult male the third pair of legs exceed the antennal scales by the length of their terminal joints, those of the female reach only to their tip. The fourth and fifth pairs of legs of the male extend as far as the third, but those of the fifth pair in the female project with their dactyli beyond the antennal scales. As has already been observed, the ambulatory legs are about as slender as those of Pal. Ritsemae. So e. g. the breadth of the propodi of the 5th pair measures in the adult male only ^/gg — '/24 of their length, in the ova-bearing females ^ac — ^'2-5 ^^ ^'^^ male of 47 mm. also ^\^- and in the young female, which is 38 mm. long, even only ^/jg. In the adult male and in the adult female the dactyli of the third pair of legs are a little longer, those ofthe fifth pair but little shorter than one third of the length ofthe propodi. In Pal. Ritsemae these joints are shorter in proportion to the length of the propodi. Closely allied to Pal. sintangensis is Pal. (Eupal.) Idae Heller, a species that has also been collected »auf Borneo" (Heller, Sitzungsber. Akad. Wiss. Wien, Vol. 45, 1862, p. 417). Pal. Idae, however, is an inhabitant of the Java Sea (vide de Man, in: Zool. Jahrb. 1897, p. 767) and may perhaps have been collected by Ida Pfeiffer in one of the sea-ports of Borneo; as far as I know this species is not yet known to live also in the rivers of that great island. The eggs of Pal. Idae are therefore probably nu- merous and small. This species attains a much larger size, the carpus of the second pair of legs has a different form and the difference in length between carpus and hand is much greater than in our new species. The eggs of Pal. (Eupal.) sundaicus Heller are also numerous and small, the ambulatory legs are less slender and the second pair of legs present different characters.

Fig. Three males from the Mandai river at Nanga Raoen and one young male from the Ketoengau river. Though no ova-bearing females of this apparently new species have been collected, I suppose nevertheless that the male specimens are adult or nearly fully developed and that Fal. {Macrobr.) callirrhoë belongs , like the two preceding, to the species of small size. The largest specimen measures only 43 mm. from the apex of the rostrum to the extremity of the telson. The rostrum of all four specimens extends to the ex- tremity of the anten 11 al scales and is slightly Notes from the Leyden ^Museum , Vol. XX. DUTCH BOHNEO-EXPEDITION. 153 directed downward, so that the apex is situated a little below the surface of the carapace ; an imaginary line that unites the points of the teeth of the upper margin , appears very slightly convex. The upper margin is armed with 9 or 10 teeth; in the specimens from Nanga Raoen the three first teeth are placed on the cephalo- thorax, the fourth above the orbital margin; in the young individual from the Ketoengau river the four proximal teeth stand on the carapace, the fifth immediately before the orbital margin. The first tooth stands justly before the middle of the cephalothorax and is a little smaller than the following; the teeth are equidistant and they occupy the whole upper margin until the apex. The rostrum is vertically rather low, though not in such a degree as in Pal. pla- cidulus de M. lu the two adult specimens from Nanga Raoen the lower margin of the rostrum presents two well-developed teeth justly in the middle, in the indivi- dual from the Ketoengau river three; the rostrum of the youngest specimen from Nanga Raoen is broken off. Examined with a lens , the carapace appears very slightly pubescent, minute microscopical hairs being scattered on it; for the rest it seems to be smooth , not scabrous. The hepatic spine is situated behind and distinctly below the antennal one. The shape of the telsoji is diffe- rent from that of the two preceding species, as may be seen by a comparison of the figures. The t el- son is less elongate, as it is comparatively shorter and broader; it appears broader to- wards the triangular apex, which terminates into a small apical spine. This spine reaches a little farther backwards than the external subtermiual spinules. The short flagellum of the internal antennae is distinctly serrate. The external maxillipedes exceed the antennal peduncle with two thirds of their terminal joint , reaching to the r^otee froixi the Leyden IMuseuiu , "Vol. XX. 154 CRUSTACEANS OF THE distal extremity of the penultimate joint of the anten- nular peduncle. The first pair of legs exceed the extremity of the antennal scales witli a third of the carpus , in the young specimens with a fourth ; the carpus of the two adult specimens is exactly twice as long as the hand, the fingers of which are about as long as the palm , the chela of the younger individuals is slightly more than half as long as the carpus. The second pair of legs are a little unequal; with the exception of the young male from Nanga Raoen , the right leg is the larger. The right leg of the male from Nanga Raoen, which measures 43 mm., is but little shorter than the body. The cylindrical merus reaches almost to the end of the antennal scales , the carpus and the hand pro- jecting beyond it. The obconical carpus is very slightly shorter than the merus, its diameter at the distal end measures ^j- of its length, so that the carpus is of a compact shape. The hand is about three times as long as the carpus and the fingers are very slightly shorter than the palm; the latter is about three times as long as broad and appears distinctly broader than the carpus, because the palm is in the middle once and a half as broad as the distal extremity of the preceding joint. The palm is a little wider than thick, the proportion being as 7:5; it is, however, not compressed, because both the upper and the under surface are transversely slightly convex and because the inner and outer margins are likewise rounded. The fingers are slender , the index makes a concave line with the inner surface of the palm ; on each finger one observes above and below a longitudinal elevated ridge that runs from the arti- culation to the tip. The dactylus (Fig. 3/) is armed with a strong and sharp conical tooth exactly in the middle of its length , a second similar though slightly smaller tooth Notes from tlie Leyden Museum, Vol. XX, DUTCH BORNEO-EXPEDITION, 155 is observed between the former and the articulation , some- what closer to the latter than to the tooth on the middle of the finger. The immobile finger presents two similar teeth ; the distal one has the same size and form as the middle tooth of the dactylus and is situated immediately behind it, the proximal just behind the proximal tooth of the other finger. A sharp cutting-edge unites on each finger the distal tooth with the pointed curved tip. The upper surface of the palm is closely covered with small thorny spinules that occur also on the outer surface; on the lower surface these spinules are somewhat larger and stand not so close together and on the inner margin they form two longitudinal, parallel rows of larger spines, between which the surface is smooth. The fingers are somewhat hairy. The carpus is covered with similar spinules, rather closely set, except on the inner surface, where larger spines form two longitudinal rows and these spines have the same size as those on the inner surface of the palm. Similar spinules are everywhere placed on the merus, and they are larger on the lower surface than on the upper. The left leg is 6 mm. shorter than the right and exceeds the end of the antennal scales by the hand and two thirds of the carpus. The latter is likewise a little shorter than the merus and both joints have the same shape as in the other leg. The chela is 2^1^ times as long as the carpus and the fingers have the same length as the palm ; the form of the palm is the same as in the other leg but it appears scarcely broader than the distal end of the carpus. The proportion of the width and thickness of the palm is the same as in the other leg. The fingers present also the same toothing, but the index is armed with a third tooth just behind and contiguous to the proximal one; they are likewise slightly hairy. As regards the spinulation of the surface of the joints, both legs agree with one another. The second pair of legs of the other male , long 41,5 mm., Pfotes from the Leyden IMuseum , Vol. XX. 156 CRUSTACEANS OF TUK are somewhat shorter in proportion to the length of the body ; the carpus is a little more slender and the spines on the inner surface of this joint and of the hand are less deve- loped , but for the rest these legs agree with those descri- bed above. The young male from the Ketoengau river likewise agrees with the preceding, in both legs the merus appears quite as long as the carpus ; the carpus of the shorter left leg is a little more slender , being slightly more than three times as long as broad at the distal extremity and the fingers are a little longer than the palm. In the youngest male from Nanga Raoen the left leg (Fig. 3^) is longer than the right and reaches with the hand and a third of the carpus beyond the end of the antennal scales; the right leg, 1,5 mm. shorter, exceeds the scales with the hand. In both legs the carpus is slightly shorter than the merus and appears a little more slender than in the adult specimens , its diameter at the distal extremity measuring scarcely one third of its length. In both legs the dactylus is armed with two , the immobile finger with three minute teeth. The distance of the distal tooth of the dactylus from the articulation is , in both legs , slightly larger than one third of the length of the finger, that of the proximal tooth exactly one fourth of it. The distance of the foremost or third tooth of the index from the articulation measures , in both legs , one third of the length of the finger , that of the second tooth from it one fourth; in the left hand the first or proximal tooth, somewhat smaller than the two others, is conti- guous to the second , in the right hand its distance from the articulation measures one sixth of the length of the finger. Minute thorny points are already developed on the inner surface of carpus and palm ; they present themselves as small spinules on the inner margin , but the outer surface of these joints is still nearly smooth. The third pair of legs extend to the end of the antennal scales , the following reach slightly less foreward. Notes from ttie Leyclen Museucn, "Vol. XX!. DUTCH BORNEO-EXPEDITION. 157 The ambulatory legs are moderately slender. The breadth of the propodi of the third pair measures '/,o — Vii of their length , the dactyli of the adult individuals measure 1/3 of the propodi or slightly less, in the young specimens they are slightly longer. The propodi of the fifth pair are as usually a little more slender, their breadth measuring 1/,^ — 1/,. of their length; the dactyli measure in the adult •/^ of the propodi , in the younger specimens they are a little longer. I may add that the meri of the third pair of the largest male are 4,6 mm. long and seven times as long as broad. The ambulatory legs are a little hairy , short fine hairs being distributed over their joints. Palaemon [Parapalaemon] Horstii de M. from Celebes is an allied species, but has a larger size. The chela of the second pair of legs, however, is not broader than the carpus, the fingers are considerably shorter than the palm and less slender, the ambulatory legs finally are still more robust , the meri of the 3rd pair e. g. are only five times as long as broad. Pal. {Macrobr.) hariensis de M. from Flores is likewise a species of small size. The rostrum is shorter and armed on the upper margin with 12 — 16 teeth. The hand of the second legs is broader in proportion to the distal extremity of the carpus and the palm is more com- pressed, namely in the proportion of 7 : 4'/2 and its inner margin is rather sharp; the palm is covered with minute rounded tubercles that stand not close together and the fingers of the larger chela are considerably shorter than the palm. Pal. (Macrobr.) pilimanus de M. from Sumatra is also a quite different species. Pal. callirrhoë is represented in the State of Santa Catharina, Brazil, by Pal. potiuna F. Mull., to which it is most closely allied. (Confer: Ortmann , Os camaroes da agua doce da America do sal , in : Revista do Museu Paulista N". II, 1897, p. 209, PI. I, fig. 9).

Notes from tlie Leyden Museum, "Vol. XX. DUTCH BORNEO-EXPEDITION. 159 As has beeu indicated in my paper quoted above, this species , that hitherto was only known to inhabit the lakes and rivers of Sumatra and Western Java, exhibits consi- derable variation in the characters of the rostrum and of the second pair of legs. The measurements given below prove that also the form of the ambulatory legs is varia- ble, that their joints appear rather robust in some indi- viduals , as e. g. in the adult male from the Upper-Sibau , in others tolerably slender, as in the adult female from Sintang. The same variation is exhibited by specimens from Sumatra, which are before me, as may be seen by comparing the specimens from the lake of Singkarah with those of the lake of Manindjau. Palaemon pilimanus belongs to those species the ferti- lized eggs of which are large. The eggs of the two fe- males from Sintang , one of which is adult , the other of middle size, are equally large, viz. 1,8 mm. long and 1,1 — 1,2 mm. broad; those carried by the small female from the Ketoengau river that is only 30 mm. long, have the same size. The eggs of Sumatra-specimens are also 2 mm. long (de Man, 1. c. p. 472). The largest specimen , the male collected in the Upper- Sibau river, is 60 mm. long from the tip of the rostrum to the end of the telson. The formula of the rostrum , that reaches to the end of the antennular peduncle, is A, the fifth tooth is placed above the orbital margin and the rostrum is directed slightly downwards. The rostrum of the adult female from Sintang extends straightly forwards , as far as in the preceding specimen , and its formula is 1 3 ; the teeth above the eyes stand closer together than the proximal and distal ones. For the other female the formula is i_3 and for the three males 9 , u and u ; for 2 2 2 1 the male from Nanga Raoen it is i '. and for the female ij.

Die nachfolgeuden Bemerkuugea sind das Ergebuiss einer Durchsicht und Vergleichuug des reichen Materials unseres Museum , das seit der letzten Catalogisirung durch Professor Schlegel (» Revue de la collection des oiseaux de proie etc. Aves Noctuae. Juillet 1873, pp. 11 — 13) noch mauchen erwünschten Zuwachs erhielt und (mit den Doubletten) 94 Exemplare ') , z. Th. in sehr instructiven Seriën enthalt. Jedes einzelne Stuck dieser betrachtlichen Reihe ist genau auf Farbung und Zeichnung, sowie Befiederuug der Laufe untersucht und nach den Localitaten untereinander ver- glichen worden, ausserdem habe ich mir noch die Mühe gegeben jedes Exemplar genau zu messen. Was zunachst die Farbung und Zeichnung anbetrifft so herrscht , wie bei so vielen Eulen , auch bei diesen Arten der Gattung Scops , eine grosse Variabilitat. Ausser dem vorherrschend graulichbraunen bis rostbraunlichen Grund- tone der Hauptfarbung kommen, bei den hierher gehörigen 1) Das British Museum besass 1875 nur 25 Exemplare der hierher gehöri- gen Arten; siehe «Catalogue of the Birds in the British Museum, vol.

JMuseum , Vol. X.X, 164 ÜBER SCOPS MAGICUS Arten, eiuzelu auch sehr duDkel(braun) gefarbte ludividuen vor, sowie solche die unterseits mehr oder minder lebliaft rostgelb oder rostroth gefarbt sind, und verbaltnissmassig nicht selten eine ober- und unterseits lebhaft rostrothe Phase, wie sie auch von anderen Eulenarten bekannt ist (z.B. unserer Ulula aluco). In wie weit diese Farbuugs- stufen von Alter und Geschlecht abhangig sind lasst sich nicht anniihernd feststellen ; als ziemlich sicher darf man aber annehmen , dass auch die ganz rothe Phase alte Vogel betrifft. Neben diesen Verschiedenheiten der Grundfarbung sind diejenigen nicht minder erheblich , welche sich auf die Farbung und Zeichnung einzelner Theile des Federkleides beziehen. So sind die braunlichgrauen bis rostbraunlichen Federchen des Schleiers bei rostrothen Exemplaren ebenfalls lebhaft rostroth , wahrend die Schleierfedern vor dem Auge (also an der Basis des Schnabels) an der Basis haufig mehr oder minder deutlich weiss erscheinen , welche Farbung zuweilen als mehr oder minder deutliches Supercilium das Auge oberseits begrenzt. (Vergl. Sharpe , Gat. PI. VII , Fig. 2). Die Schleierfederchen der Ohrgegend sind hinter- seits meist von einem schmalen schwarzen halbmondförmigen Bogen begrenzt, der indess sehr haufig nur theilweis sicht- bar ist , zuweilen ganz fehlt. Die grossen Schulterdeckeu zeigen am Ende der Ausseu- fahne in der Regel einen grossen , weissen , bis blassrost- gelblichen , bei rotlien Exemplaren meist blassrostrothen Fleck, der aber haufig mehr oder minder verdeckt ist oder selbst ganz fehlt, well die betreffenden Federn mehr oder minder stark dunkel vermiculirt resp. quergebandert sind. Aehnlich verhalt es sich mit den weissen oder blassfablen Endflecken der vorderen Deckfedern der Armschwingen , sowie einiger der vorderen grössten oberen Flügeldeck- federn , welche indess nur ausnahmsweis sehr deutlich sicht- bar hervortreten. Endlich mag noch erwahnt sein , dass bei manchen Exemplaren der weisse Grundton auf Bauch und auf den Bauchseiteu etwas deutlicher bemerkbar ist, dass Notes from the Leyden IMuseutn, "Vol. XX. UND DIE VERWANDTEN ARTEN. 165 solche Individuen aber auch bei Scops riitüus (von Mada- gascar) vorkommen. Die Befiederung der Tarsen , mit kurzen dicbtstehenden , zuweilen mehr sparlich gestellten Federchen, erstreckt sich meist auf die oberen zwei Drittel bis vier Fünftel der Vorder- seite, haufig mehr oder minder auch auf die Hinterseite des Laufes, zuweilen reicht sie auch bis zur Basis der Zehen herab. Bei der Werthschatzung dieses Characters ist die Praparatiou des betreffenden Exemplares sehr zu be- rücksichtigeu ; denn nicht selten ist beim Trocknen oder Aufweichen des Balges die Befiederung der Tarsen mehr oder minder beschadigt worden, ja zuweilen ganz verloren gegangeu. Dagegen zeichnet sich Sc. sulaënsis durch fast nackte Laufe aus. Einige der soeben erwahnten Verschiedenheiten sind als characteristisch zur Aufstellung besonderer Species oder Subspecies benutzt worden , deren Werth sich bei Ver- gleichung grosser Reihen indess meist nicht halten lasst. Ueberdies sind auch die ausführlichsten Beschreibungen (wie sie z.B. Sharpe giebt) völllg ungenügeud um Exemplare (zumal ohne sichere Lokalitatsangabe) darnach zu bestim- men, und selbst die brauchbareu Abbiklungen (PI. V — VIII) welche wir Sharpe zuerst verdanken , sind dafür nicht ausreichend. Soweit ich nach dem von mir untersuchten Material zu urtheilen vermag, scheinen mehr als alles Andere zwei Charactere zur Unterscheidnng der Arten von Werth, namlich : die Zeichnung der Schwingen und die Grössenverhaltnisse. Beide Eigenthümlichkeiten habe ich in den beifolgenden genauen Abbildungen der ersten Schwinge (rechts , von der Unterseite gesehen) darzustellen versucht, sowohl um die vorherrschende Zeichnung, als die hauptsachlichsten Abweichuugen zu zeigeu. Die letzteren sind freilich bei allen hierher gehörigen Arten sehr erheblich und ich will nicht verhehlen , dass Individuen vorkomnien könneu und werden , die auch nach diesem illustrirten »Key", zu Bedenken Anlass geben. Notes from the Leyden Museum, Vol. XX. 166 ÜBER SCOPS MAGICUS Die haufig fehlenden oder unzuverlassigen Geschlechts- angaben erschweren die Bestimmung und stehen nicrht selten mit der auch für diese Arten gültigen Grössenver- schiedenheit der Geschlechter (Mannchen kleiner als Weib- chen) im Wiederspruch. Immerhin werden die beigegebe- uen vergleichenden Messungen von Nutzen sein , die trotz betrachtlichen Schwankungen doch immerhin gewisse An- haltspunkte geben , wobei besonders auf die Lange der er- sten Schwinge hiugewiesen sein mag. Sie ist unter den angegebenen Artcharacteren von der Basis au gemessen , die Figuren der Tafeln zeigen dagegen die erste Schwinge (und zwar die des reebten Flügels von der Unterseite) nur soweit sie nicht von den unteren Deckfedern bedeckt ist. Dabei ist bei Figur 3 — 10, der Einfachkeit halber , dieselbe Grosse beibehalten worden ohne Rücksicht auf das Ge- schlecht , deren Untersehiede ja aus den Artcharacteren er- sichtlich sind. 1.

The ruff and ear-coverts are ochraceous buff, and there is no sign of white on the scapulars , which are externally yellowish ; the entire up- per surface is very strongly banded with fulvous". Die ausfiihrliche Beschreibung, welche Sharpe giebt bezieht sich auf die seltenere mehr rostbraunliche Farbungsstufe (» sandy buff"), wahrend die Abbildung (PI. V) die ober- und unter- seits rostrothe Phase darstellt. Letztere ist unter den 23 Exemplaren , welche das Reichs Museum von Amboina und Ceram (durch Dr. S. Muller, Hoedt, Teijsmann, van Mus- schenbroek und Schadler) besitzt (gegen 4 im British Mu- seum) in acht Exemplaren vertreten. Zwei derselben (N^. 5 und S) zeigen die langsten oberen Schwanzdecken einfar- big tief rostroth. Die vorherrschende Grundiarbung der Oberseite ist ein mehr oder minder rostfarben verwasche- nes Braun , die des Schleiers fahlbraunlich , bei mancheu Exemplaren heller , fast braunlichweiss oder grau ; der weisse Superciliarstreif ist bei manchen Exemplaren so deutlich als auf der Abbildung bei Sharpe (PI. VII, Fig, 2) ; der zu- weilen sehr versteckte Schulterfleck ist meist weiss und nur selten blassrostgelblich verwaschen , zuweilen auch auf der Aussenfahne rostfarben und schwarz quergebandert. Mit die- ser Farbungsstufe stimraen auch die beiden noch von Dr. Sal. Muller in 1828 auf Amboina gesammelten Exemplare (Kat. N°. 1 u. 2; Schleg. Cat. 1862, N". 2 u. 3) überein, welche als Typen der Art betrachtet werden dürfen. Das eine derselben (N". 1) war mit Temminck's Hand- schrift als „Strix hemipodia-magica" bezeichnet.

Der Bauch erscheint etwas heller fweisser) , doch nicht mehr als bei gewissen Exemplaren von Amboina (N". 10) und Ceram (N". 15). Unter den Exemplaren von Halmahera (Dr. Bern- stein 1861 ; V. Rosenberg 1870) zeichnet sich namentlich ein jüngeres Mannchen (N". 36) durch helleren (weissen) Bauch aus, dasselbe zeigt aber die versteckten weissen Schulterflecke noch quergebandert , wahreud alte Vogel (z. B. N". 35 u. 36), ebenfalls mit hellem Bauch, deutliche grosse weisse Schulterflecke besitzen. Die Federn des Schleiers sind raeist braunlich (ganz so gefarbt wie bei Amboina-Exemplaren) , die an der Schnabelbasis zuweilen weiss, welche Farbung sich auch als mehr oder minder deutliches Supercilium über den oberen Augenrand fort- setzt (vergl. Sharpe PI. VI und VII , Fig. 2) , wie dies auch bei Exemplaren von Amboina , Ceram , Buru und Celebes der Fall ist. Manche Exemplare von Halmahera (z. B. N''. 37) sind auch auf der Unterseite ebenso dunkel gefarbt als solche von Amboina. Die Querbindenzeichnung des Schwanzes ist übrigens bei keinem unserer Exemplare so deutlich markirt als dies die Abbildung bei Sharpe (PI. VI) zeigt, wobei noch bemerkt sein mag, dass die Zeichnung der Schwanzfedern in mehr oder minder deutlichen , oft nur vermiculirt angedeuten- den Querbinden so ausserordentlich variirt, dass sich kaum eine allgemeiu guitige Beschreibung geben lasst. Dunenjunge , mit mehr oder minder in der Entwicke- lung begriffenen Schwingen und Schwanzfedern , zeigen feine dunkle Querbanderung (wie der Nestvogel von Am- boina).

Ura Wiederholungen zu vermeiden will ich nur bemerken , dass unsere Exemplare von Ternate (Dr. Bernstein 1861, von Rosenberg 1872, van Musschenbroek 1878) durchaus mit solchen von Amboina , Halmahera u. s. w. überein- stiramen und die von Sharpe angegebenen Charactere in keiner Weise als constante bestatigen. Die Abbildung (PI. VII, Pig. 1) zeigt ein dunkel gefarbtes Exemplar von Sc. magicus^ wie solche auch auf Amboina vorkommen.

Erste Schwinge (von Basis an) 63 — 77 mm. lang (Mannchen) oder 80 — 87 (Weibchen) an Aussenfahne (von unten gesehen) mit 6 hellen Querbinden (wie Fig. 3, 5 u. 6), ausnahmsweis nur mit 5 (wie Fig. 4) oder mit 7 — 9 (wie Fig. 7); an Innen- fahne meist mit 6 hellen Randflecken oder undeutlichen Querbinden (wie Fig. 3), die sich nur bei jüngeren Vögeln zu mehr oder minder deutlichen Quer- binden gestalten (wie Fig. 5 u. 6) , ausnahmsweis mit 7 undeutlichen Randflecken oder Querbinden (wie Fig. 7) , oder nur mit 2 Randflecken (Pig. 4: rothe Phase). Die übrigen Sch wingen zeigen aussen 6 — 7 (ausnahms- weis 8) helle Querbinden (meist 6 deutlich) ; die Innen- fahne der Handschwiugen erscheint mehr einfarbig als bei den verwandten Arten , nur der Spitzentheil zeigt 3 — 4 hellere , aber dunkel vermiculirte Querbinden , der Basistheil Notes from the Leyden Museum , Vol. XX. 174 ÜBER SCOPS MAGICUS 3 — 5 helle einfarbige Raudflecke (ahnlich Fig. 3), die nur bei juugen Vögeln (wie N". 1 u. 4) deutliche Querbinden bilden (wie Fig. 5 u. 6); die Armschwingen zeigen 6 — 7 Raudflecke, die bei jungen Vögelu über beide Fahnen laufen. Bei zusammengelegten Flügeln zeigen die Hand- schwingen aussen meist 5 helle Querbinden ; die Unterseite der Schwiugeu 5 — 6 helle Querbinden (zuweilen nur 3). Laufe, Zehen und Krallen erheblich schwacher und zier- licher als bei Sc. magicus ; der Lauf vorn meist bis zur Zehenbasis befiedert auch auf der Hinterseite (wie dies die Figur bei Sharpe S. 77 richtig zeigt). Verbreitung: Celebes (Makassar, Minahassa); Sangi, Wetter, Flores , Sumbawa'), Lombok. Mit Ausuahme der zwei letzteren Lokalitateu ira Reichs- Museum durch 24 Exemplare vertreten (gegen 5 im British Museum von Celebes und Flores). Die Vergleichung dieser ansehulichen Reihe lasst keinen Zweifel , dass «Sc. manadensis keineswegs uur als eine Subspecies , sondern als eine von «Sc. magicus verschiedene , sogenannte »gute" Species be- trachtet werden muss. Sie unterscheidet sich schon leicht durch die merkbar geringere Grosse, da auch die grosseren Weibchen von «Sc. manadensis immer kleiner sind als die grössten Mannchen von «Sc. magicus , Verhaltnisse die bei Exemplaren mit richtigen Geschlechtsangaben kaum Zweifel lassen werden. Lauf, Zehen und Krallen sind viel zierlicher als bei «Sc. magicus und der Lauf ist ringsum bis nahezu oder ganz bis zur Zehenbasis dicht befiedert. Die Schwingen sind im Allgemeinen nicht so deutlich quergebandert als bei «Sc. magicus ; wo dies aber, wie bei jüngeren Vögeln , vorkommt, sind die Querbinden minder zahlreich , wie dies die Figuren auf Taf. 9 zeigen. Wenn hier z.B. Fig. 7 an der Aussenfahne ebensoviel helle Querbinden (9) auf der Aussenfahne aufweist als «Sc. magicus (Fig. 1), so unter- 1) Pisorhina albiventris Hartert, Nov. Zool.

UND DIE VERWANDTEN ARTEN. 175 scheidet sich dies Exemplar doch uoch durch den Mangel deutlicher Querbinden au der Innenfahue. lm übrigen ist Sc. manadensis in Gesammtfarbung wie Zeichnung ein getreues kleinerer Abbild von Sc. magicus , und die bei letzterer Art erwahnten individuellen Abwei- chuugen , (grössere oder geringere Ausdebnuug eines weisseu Schulterfleckes , helle (weisse) Endflecke auf den vordersten oberen Deckfedern , Weiss an der Basis der Schleierfederu an der Schnabelbasis , zuweilen als mehr oder minder deutliches weisses Supercilium den oberen Augeurand be- grenzend), kommen auch bei «Sc. manadensis vor. Manche Exeraplare sind nur auf der ünterseite rostroth , andere ganz rostroth gefarbt, doch scheint diese rothe Phase (uuter 24 Exemplaren uur 4) seltener als bei Sc, magicus. Ausser dieser rothen Phase kommt auch noch eiue ober- und unterseits sehr dunkelbraun gefarbte Farbuugsstuf'e vor, die merkwürdiger Weise bis jetzt noch nicht zur Begründung einer eigenen Art benutzt worden zu sein scheint.

Hierzu kommen noch die Ver- schiedenheiten in der Zeichnung der Schwingen , wie ich dieselben vorher darzustellen versuchte, Mit Ausnahme eines Exemplares aus dem Siiden (Macas- sar: Teijsmann 1878) stammen alle übrigen Exemplare unseres Museum aus der Minahassa im Norden her (Goron- Notes from ttie Leyden Musemn, Vol. XX. 176 ÜBER SCOPS MAGICUS talo : Dr. Forsten 1841, v. Rosenberg 1864; Manado' Renesse van Duivenbode 1866; van Musschenbroek 1878 und von Faber 1883). Das Exemplar von Macassar (N". 1) gehort zur rothen Phase, zeigt einen grossen weissen Schulterfleck und die vorderen Deckfedern der Scb wingen, wie die vorderen grösten Deckfedern am Ende breit weiss, wahrend ein anderes rotbes Exemplar (N''. 3) nur einen kleinen ver- steckten rostgelblichen Schulterfleck aufweist. Einzelne Exemplare (z.B. N". 1, 6 und 13) haben die Bauchpartie so hell (weiss) gefarbt als solche von Flores und Wetter, Die Exemplare N°. 5 und 9 geboren zu der auffallend dunkleu Farbungsstufe , die ich vorher erwahnte. Auch die Befiederung des Laufes ist hier (anstatt weisslich bis rost- braunlich) tiefbrauu (mit rostbraunen Querbandern). Die Innenfahne der Handschwingen ist bis auf 2 — 3 undeutliche rostfahl vermiculirte Querbinden des Spitzentheiles einfarbig schwarz ; dagegen zeigen die Armschwingen die gewöhn- liche Zeichnung. Dunenjunge sind ganz so gefarbt und gezeichnet als bei Sc. magicus, unterscheiden sich aber schon durch die fast bis zur Zehenbasis befiederten Laufe. Von den Sangi Insein (Kat. N^. 15; Schleg.

Wallace) auf- gestellt, das Sharpe wie folgt als eigene Subspecies charac- terisirt: »It has a distinct wash of grey on the upper surface and has the cheeks greyish white; but the principal diffe- rence lies in the white belly, where it is the prevailing colour, the cross-markings and lines being very scanty." Bei einer grosseren Reihe von Exemplaren erweisen sich die angegebenen Kennzeichen als nicht stiehhaltig. Unser Exemplar von Flores (N"'. 16 Larantuka : Semme- link 1863), oberseits rostroth gefarbt, ist ganz so als ein anderes oberseits rostrothes von Celebes (N^. 11); dasselbe gilt bezüglich eines Exemplares von Wetter (N", 18: Hoedt 1866) im Vergleiche mit Exemplar N^. 1 von Macassar. Das Exemplar von Flores zeigt auf der Aussenfahne der ersten Schwinge 7 helle Querbinden, zwei andere von Wetter die gleiche Zahl (eins, N*^. 19, sogar 9, wie Fig. 7), allein andere Exemplare von dieser Insel (in Spiritus durch Schadler 1898 eingesandt) zeigen dieselbe Zeichnung als Exemplare von Celebes (wie Fig. 3). Unter den kürzlich durch Schadler von Wetter einge- sandten Exemplaren gehören zwei zu der ober- und unter- seits lebhaft rostroth gefarbten Phase. Sehr nahe verwandt damit scheint Sc. {Pisorhina) alfredi Hartert (Novit. Zool. IV, 1897, p. 527; id. V, PI. 1, Fig. 1) von Flores (Coll. Everett); auch bei Sc. manadensis ist zuweilen nur » one- fifth of tarsus bare"; im übrigen ergeben Beschreibung , Maasse und Abbildung bei Hartert keinerlei durchgreifende Unterschiede mit unseren rothen Exemplaren von Wetter. Meyer und Wiglesworth betrachten auch die folgende Art als Subspecies von Scops inanadensis : Scops sibutuensis Sharpe. Buil. B. O. C. N°. XII, p.

Sharpe hat bereits auf diese Verhaltnisse hingewiesen (Cat. II, p. 78) und sagt in Betreif der Fleckeuzeichnuug der ersten Schwinge »m S. menadensis the spots are 8 or 9 in number, in S. rutilus they are no more than six" giebt also fur beide Arten mehr helle Flecke an , wahr- scheinlich weil die unter den Deckfedern versteckten mit- gezahlt wurden. Soweit diese Fleckeu oder Querbinden sichtbar sind ohne die Deckfedern aufzuheben , machen sich bei Sc. manadensis in der Regel 6 , bei Sc. rutilus nur 5 bemerkbar. Freilich kommen ausnahmsweis auch bei Sc. manadensis uur 5 helle Querbinden auf der Aus- senfahne vor , wie Fig. 4 zeigt , aber dies ist ein Exem- plar des rothen Phase (N'\ 3) und hat die Innenfahne fast einfarbig, wahrend rothe Exeraplare von Madagascar hier mehr oder minder deutliche Querbinden (6) aufzuweisen haben. Dies gilt auch bezüglich der Zeichnung der übrigen Schwingen, deren Innenfahne zwar nur verwischte, ver- miculirte Querbinden zeigt, die aber immerhin deutlicher bemerkbar sind als bei Sc. manadensis^).

Bei zusammengelegteu Flügel sind auf den Handschwin- gen meist 4 helle Querbinden sichtbar; auf der Underseite der Schwingen 3 — 4 (selten 5) helle Querbinden. Die Laufe sind bis fast zur Zehenbasis herab befiedert, auf der Rückseite anscheinend nicht so dicht als bei Sc. manadensis. Die haarahnlichen verlangerten Schafte der Schleierfedern an der Schnabelbasis erscheinen bei manchen Madagascar-Exemplaren auffallend lang (bis 33 mm.)> sind in der Regel aber nicht langer als bei Sc. manadensis (21 — 23 mm.). Tm übrigen stimmt Sc. rutiliis , sowohl in Grosse, allge- nieiner Farbung wie Zeichnung des Gefieders durchaus mit "Sc. manadensis überein , auch hinsichtlich der mehr oder minder grossen (haufig versteckten) weissen Schulterflecke. Der helle (weisse, aber dunkel vermiculirte) Superciliar- streif scheiut dagegen minder haufig vorhanden als bei Sc. manadensis und ist nur bei einem unserer Sc. rutilus sehr deutlich vorhanden. Dasselbe gilt für die weissen En- den der obersten grössten Deckfedern , welche auch nur an einem Exemplare bemerkbar sind. Dagegen giebt es Exem- plare mit hellerem Bauch, ahnlich wie die Form :»albi- ventris'" von Sc. manadensis , und wie bei der letzteren Art unterseits rostrothe Exemplare (N^. 5) , sowie eine lebhaft rostrothe (N°. 4 u. 12) und sehr dunkelbraune Phase (N". 7). Diese letztere ist jedenfalls identisch mit Sc. capnodes Gurney von den Comoren (Anjouan), von woher mir kein Exemplar zur Hand ist.

AND DESCRIPTION OF A NEW SPECIES FROM ZANZIBAR B? Dr. ANGELO SENNA, Assistent in the R. Museum at Florence. Some time ago I have had occasion , in speaking of the genus Cerobates Schh. ^), to note the logical position in the Brenthids arrangement of the genus Jonthocerus Lac. after the suppression of the subfamily Ephebocerinae lately proposed by Prof. Sharp. This position is among the Stere- oderminae near Cerobates to which the genus Jonthocerus is allied. In this subfamily, Jonthocerus represents the South American genus Ephebocerus Schh. of the Tracheli- zinae. The characteristic of all the species of this genus is, in the males, the remarkable development of the eyes oc- cupying often the greater part of the head, and the long and slender antennae clothed with delicate hairs. The females have the eyes smaller and normal, the antennae shorter and more robust; it is not easy to distinguish them from Cerobates. The genus has a wide geographical distribution, its species inhabiting Ceylon, Upper Burma, Penang, Singapore, Saigon, Japan, Borneo, Sumatra, the Andaman andMentawei Islands, Java, New Guinea, Australia, finally Zanzibar and Cameroon. 1) Notes Leyden Museum, Vol. XVII, p. 209, 1896.

The species are moderately numerous and all probably live under the barks of the fallen trees, like J. nigripes ^ observed by Mr. Lewis in Japan. Two species , J. sondaicus and J. foveolatus , described by me are imported in Europe with dry tobacco from Sumatra. In the following table I indicate all the species known to me at present and, subsequently treating of each species, I give only the taxonomical characters, being of opinion that anyone using these diagnoses has made himself fami- liar with the generic characters.

Though we kuow already several species of this genus from the Malay Archi- pelago, thanks the careful in- vestigatons of Dr. Sluiter, du- ring his stay at Batavia V), the present specimen could not be identified with one of them. The body of our specimen (fig. 1) has a nearly cylindrical shape; it measures '^^j^vam.. in breadth, its length being about eight times greater (26 mm.). The colour of the body is brownish-yellow, that of the anal and terminal shields dark brown, almost black. In the anterior half 1) Beitrage zu der Kenntniss der Gephyrëen a. d. Mai.

On a distance of 3 mm. from the terminal shield, nearly on the place where the retractor- muscles are attached to the body-wall, the skin shows a girdle-shaped area of a glistering appearance. The cutaneous bodies (Hautkörper) are not very densely scattered over the surface of the body; they resemble those of ^. Steenstrupii (Selenka, die Sipunculiden, taf. XIII, fig. 191), but only a single glandular opening could be detected , somewhat by the side of the centre. The anterior and posterior shields have about the same size , but not the same shape ; the first of them is elliptical and lies at an oblique angle to the trunk. It is convex and divided in a great number of small polygonal areas, consisting of a dark brown chitinous substance ; on the passage between this shield and the adjacent skin , similar areas are visible over a narrow space, but they are only surrounded by a dark brown margin. The posterior or terminal shield is of a paler colour, circular and concave; its margin is also divided by grooves in numerous polygonal areas. The proboscis or introvert is very short, about 8 mm. long, though he may perhaps not be totally protruded. Its terminal part is, over a third of its length, densely beset with parallel rows of small brown hooks, the remain- ing posterior part showing larger hooks, irregularly scattered. The smaller hooks (fig. 4) are only 0.048 mm. high ; they have the shape of a triangular pyramid , with a large convex face and two smaller concave ones. The edge between the two latter faces bears a small , hardly visible tooth in its basal half. The hooks of the basal part of the proboscis are two and a half times larger and look like conical spines, faintly bent and furnished near their base with several prominent ridges. Between both kinds of hooks the usual conical excretory ducts of glands can be observed. Notes from the Leyden IMuseiiiii, Vol. XX. ASPIDOSIPHON CYLINDRICUS. 197 The layer of longitudinal muscles is continuous, of glister- ing appearance, much thicker in the anterior third part of the body, where at the dorsal side some irregular slits are visible. Two strong retractor-muscles (fig. 2) are attach- ed with broad base near the caudal end of the body, on about ^/- of its length, the left a trifle more anteriorly than the right one; they are fused nearly in the middle of the body. The spiral of the alimentary canal shows nine double coils and is furnished with a complete spindle- muscle, which is attached in the middle of the posterior shield. An other muscle (Befestiger) arises from the place of passage of the oesophagus into the intestinal spiral , passes through the angle between the two retractor muscles and is attached to the body-wall at the left of the nerve-cord. A diverticulum could not be observed. The nephridia are long and slender; they do not extend quite till the end of the retractor-muscles, and the right appears not to be so long as the left one. Over a great part of their length the nephridia are fixed to the body-wall by a mesenteric ligament. Of the ten species of Aspido siphon , observed in the Indian Ocean , our specimen most resembles in its external appearance A. Steenstrupii Dies. ^); however, this species belongs to the group having the longitudinal muscles split up into bundles. In structure it more agrees with A. ravus, found by Sluiter in the bay of Bantam and kindly placed by him at my disposal for comparison '^). This species , however, differs from the Kisser-specimen in several external and internal characters. Its body is only 5^/2 times as long as broad , the anal shield is finely 1) Selenka, de Man und Biillow, Die Sipuncnliden, Taf.

It belongs to the division I (base of elytra coloured as the apex), A (elytra with four convex flavous spots), h (pronotum finely and evenly punctured, without raised patches), but it has the prosternum neither entirely fulvous {x), nor fulvous in the middle with the lateral portions metallic green (/3) : in the new species the prosternum is entirely of a dark metallic green colour. & Helota Candezei , n. sp. cf • Length G'/.^ mm. — Subshining; above dark bronze green with purple tinges along the middle of the elytra, especially round the elytral spots; antennae dark pitchy approaching to black ; the elytra provided with two pairs of small con- vex flavous spots which are placed between the 2)^^ and 6*^ striae; the anterior spots are larger than the posterior ones. Underneath the head , the prosternum and the elytral folds are dark bronze green ; the raeso- and metasternum , the abdomen , the coxae and the femora (the tip of the latter excepted) reddish testaceous; the tip of the femora and the entire tibiae and tarsi are dark pitchy , the claws reddish testaceous.

The prothorax is at the base distinctly broader than long, and narrows in slightly curved lines towards the front- margin ; the sides are indistinctly crenulate , the front- margin is curved backwards, the anterior angles are slightly protruding; the base is deeply bisinuate, the basal angles are acute, the median lobe is truncate; the upper surface is covered with punctures which become larger and more closely set towards the lateral margins; in front of the scutellum a longitudinal impunctate streak is present on the basal half, and it is accompanied on each side by a large but indistinct impression. The scutellum is strongly trans- verse , glossy and impunctate. The elytra are subparallel narrowing somewhat to the apices which are slightly dehiscent and almost conjointly rounded. Each elytron is provided with ten regular rows of punctures (the iC^li j-qw is marginal); the punctures of the 7tli — IQA rows are larger than the others; the inter- stices are provided with some extremely fine punctures and become more or less costate towards the apex, especially the 3"! and Qtt which extend to the apical margin. The under surface of the head shows in the middle very distinct but rather remotely placed punctures , on the lateral portions the punctures are very close together. The middle of the prosternum is sparsely punctured , on the sides how- ever the punctures are larger and more densely set. The middle of the metasternum is impunctate, the abdomen finely but very distinctly punctured. The apical ventral segment is flattened , transversely impressed before the apex which is broadly truncate. The tibiae are provided with large punctures, the anterior ones are strongly curved.

ON PERICHAETIDAE. 201 NOTE XXIX. ON THE VARIABILITY OF CHARACTERS IN PERICHAETIDAE BY Dr. R. HORST. Every one occupied with the study of Perichaetidae , no doubt will be persuaded , that too much species of this genus are based on a single specimen , that showed some slight diSerences from well-known type-species, whether by its being not quite mature, or by the variability of some of its organs. In a recent paper Michaelsen ^) as well as Benham ^) especially called attention to this fact and urged the necessity of examining as many individuals of a species as possible , to augment our knowledge of the variability of the characters of these worms and of their value for the discrimination of the species. Whether Michaelsen is right in uniting so many species of Perichaeta, as done by him in his paper, above referred to, I hope to discuss later on; for I think Benham rightly says: » until we know more of the variability of the animals we are justified in regarding a given position as 'fixed, if any considerable number of specimens reveal it." In the present paper I wish to point out for a couple of them the varia- bility of some characters always used in differentiating Perichaeta-apecies , viz. the number of spermathecae, and the number and arrangement of copulatory papillae. 1) Oligochaeten in Kükenthal's Ergebn. einer Zodog.

Lens, Surgeon of our West-India army, kindly forwarded me a bottle with earthworms, collected in Paramaribo. Among them there are several examples , which must be identified with P. biserialis Perr. '), though this species hitherto is not ob- served in South-America , and only mentioned from the distant isles of Madagascar and the Philippines. Like several other earthworms this species therefore appears to have a very wide distribution, probably due to man's interference. According to the investigations of Perrier ^), Beddard ^) and Michaelsen '') P. biserialis is distinguished by the following characters: chaetal ring on a prominent ridge, presenting a ventral gap , on each side of which there is an enlarged bristle , forming thus behind the girdle an apparent longitudinal row of setae on the left and the right of the ventral median line ; upon the segments in front of the girdle, except the anterior ones, two or three setae on each side are thus enlarged. The male generative pores situated on prominent, conical papillae upon segment XVIII and the 3 to 7 succeeding segments each with a pair of copulatory papillae in positions nearly corresponding with them. First dorsal pore in the intersegmental groove XII/XIII. The fifth, sixth and seventh septum are specially thickened; for Beddard's assertion that they should lie one segment more posteriorly 1 think to be erroneous. Two pairs of spermathecae, opening into the intersegmental grooves V/VI and VI/VII, consisting of a globular main pouch , with short excretory duct and a tubular diverticulum, extending over 2/3 of its length. i) The collection contained also P. posfAuma Vaill., P.

The two specimens examined by Beddard and first iden- tified by himself with P. hiserialis , afterwards were des- cribed as belonging to a new species, on account of the absence of spermathecae; however, I cannot agree with his assertion , as will appear from the following. Perrier, who in 1875 first described P. hiserialis from the Philippines, already pointed out the variability of the number of copulatory papillae in this species; he says »ou peut en effet constituer une série d'individus presentant, en arrière des orifices males , de chaque cote de la ligne médiane veutrale , une rangée de trois, quatre , cinq, six ou sept papilles. Quelques iudividus ont même trois , quatre ou cinq papilles d'un cote, quatre, cinq ou six papilles de I'autre." In 1890 Beddard examined two specimens from Manilla, both characterized by the presence of 5 pairs of copulatory papillae. In the foregoing year Michaelsen published a detailed description of the same species , based on the examination of five individuals, collected in Madagascar. He confirmed the variability of the number of copulatory papillae , for of these specimens four showed but 3 pairs of papillae , while the fifth one had 5 pairs of them. My own observations about the worms from Surinam are quite in agreement herewith. Eight mature worms came under examination and of these two have 4 pairs of copulatory papillae on segments XIX — XXII ; three of them show only 8 pairs on segments XIX — XXI; one specimen has 3 papillae on segments XIX — XXI at the right side, and on segments XX — XXII at the left, while on both remaining worms one has only 3 papillae at the right, the other one at the left side of the body on segments XIX — XXI. None of them thus showed the number of 5 pairs of papillae , as observed by the above- named naturalists. In our specimens, however, the variability is not ZVotes from ttie Leyden Museutn, Vol. XX. 204 ON PERICHAETIDAE. limited to the number of papillae; they also show remark- able differences in the number of spermathecae. Only in a single specimen two pairs of spermathecae were observed in segments VI and VII; they agree rather well with Michaelsen's description , though I found the main pouch more pear-shaped than globular and the diverticulum only extending till the half of its length in stead of two thirds. Considering however that the shape and size of this pouch depends somewhat on the state of being more or less filled, I think no much value can be ascribed to those differences. Of the seven remaining worms one spe- cimen (with 4 pairs of papillae) only shows a single spermathecal pore at the left side in the intersegmental groove V/VI, corresponding with a spermatheca without diverticulum in segment VI ; another specimen (also with 4 pairs of papillae) has three spermathecal pores in a row in the same situation. Comparing the spermathecae of the last individual with those of the first one , the main pouch proves to be somewhat more slender and the diverticulum does not extend quite till the half of its length. In the fourth specimen also at one side (the right) spermathecal pores are visible, 4 in the intersegmental groove V/VI and 3 in that between segments VI and VII. On the contrary in four other specimens no trace whatever of spermathecal pores or spermathecae could be found; they agree in this character with both individuals examined by Beddard , and represent , I think , his species P. acystis. As Benham already suggested , that in this species the spermathecae might perhaps be not yet functional and therefore extremely minute like in some specimens of Lumbricus herculeus with fully-developed sperm-sacs and clitellum, I made transverse sections of one of our worms , but no trace of spermathecae was visible. Also the arrangement of the setae showed some irregu- larity in a couple of worms. Ordinarily the distance between both enlarged ventral bristles measures four times the usual distance; on some segments, however, it can amount Notes from the Leyden ]VIuseu.ni, Vol. X.X. ON PERICHAETIDAE. 205 till five or six times that distance, and thereby the con- tinuity of the series of large setae is also broken oS. In the number of setae our worms agree very well with Michaelsen's statement; I found on segment X 83 bristles, while he mentions 81 on segment V and 90 on segment X. The length of the enlarged setae is two and a half to three times that of the ordinary ones; at their distal extremity they are ornamented with obvious transverse grooves. Similar variations in the number of spermathecae were already observed by Beddard some years ago in a lot of worms from Manilla belonging to P. posthuma^); besides normal specimens with four pairs of spermathecae, he found one individual with three pairs of them , another one with no trace whatever of spermathecae , while in one specimen there were in segment VIII on the right hand three spermathecae in a row, instead of a single. Perichaeta Stelleri Mich. (P. Everetti Bedd., P. papillata Bedd., P. saraioacensis Bedd., P. kinabaluensis Bedd.). In 1891 Michaelsen described a remarkable PericJiaeta- species ^) from the Sangi-isles, distinguished by the fact that it possesses numerous (16 — 28) spermathecae in segments VI and VII , furnished with diverticula , which are swollen at their base.

In Kiikenthal's Ergeb- nisse einer zoologischen Forschungsreise Michaelsen describes another badly preserved specimen of P. Stelleri from Borneo , with 5 and 9 spermathecae in segments VI and VII respectively, and he makes the suggestion that the above-named species of Beddard all could be identified with his P. Stelleri. I think Michaelsen's suggestion quite right, for the number of papillae and spermathecae, characterizing Beddard's different species appear not to be constant, but liable to much variation. I had the opportunity to examine a great number of Perichaeta-specimens , collected by Dr. Biittikofer in Western-Borneo (Poetoes Sibau, Nanga raoen , the Liang Koeboeng) ; they agree with each other externally in the presence of a pair of papillae on several segments behind the male pores, internally in the presence of more than one pair of spermathecae in segments VI and VII, and the absence of intestinal coeca. They all I believe must be identified with P. Stelleri and are characterized in the following manner. The length of their body varies from 115 to 300 mm.; the number of segments amounts to 150. The colour is is olive-brown, violet on the upper side, often with a dark line in the dorsal mid-line; chaetal circles whitish. Cephalic lobe extending over two-thirds of the buccal segment, which is longitudinally folded. Setae on a pro- minent ring in front of the clitellum , with obvious dorsal Notes from the Leyden M^useum, Vol. XX. ON PERICHAETIDAE. 207 gap; 54 of them on segment VI, 68 on segment XIX. The ventral setae are straighter and longer than the dorsal ones. No setae on clitellum. First dorsal pore in the in- tersegmental groove XII/XIII. Several small spermathecal pores in a transverse row, in the grooves between segments V and VI, VI and VIL Oviducal pore single, on an oval area upon segment XIV. Male pores , on prominent conical papillae, formed by a longitudinal crescent fissure with crenulated lateral margin. In the interspace between the male pores 12 to 14 setae; their number is somewhat variable, and depends on the development of the papilla. The number of pairs of copulatory papillae on the suc- ceeding segments is different in several individuals. In most of them there are four pairs of papillae on segments XIX — XXII ; but this number can increase to eleven pairs and decrease to a single one. On comparing the number of papillae of different in- dividuals they will prove to form an almost uninterrupted series, as demonstrated by the following table: LengI XIX. XX . XXI.

Museuin , Vol. X.X. 208 ON PERICHAETIDAE. XXVII and a single papilla on segment XXVIII at the right ventral side, so we may conclude that of the tenth pair the left one is not developed. In a third specimen (e) we find 9 papillae at the left and 3 at the right ventral side, forming a complete pair only on segments XIX, XXVI and XXVII, while on the interposed segments (XX — XXV) the right papilla is not developed. Next follows an inter- ruption in the series , for specimens with 7 and 8 pairs have not been observed by myself, but an individual (d) collected on the Liang Koeboeng showed 6 pairs on segments XIX — XXIV. Another specimen {e) presents 4 pairs of papillae on segments XIX — XXII and a single one, at the right side , on segment XXIII ; it is likely that of the last pair the left papilla was not developed. In another individual there are no papillae on the anterior segments XIX and XX, but segments XXI and XXII show a pair of them and segments XXIII a single one ; it may be presumed that in this specimen both anterior pairs of papillae and one of the last pair are checked in their development. Specimens with 4 pairs of papillae on segments XIX — XXII, like ƒ, are very common; even in immature individuals, without clitellum, these papillae are recognizable. A specimen, that has only two pairs of papillae on segments XXI and XXII, but wants those on the two preceding ones, belongs to the same category. In the worms from Nanga raoen there are but 3 pairs of papillae visible on segments XIX — XXI (g). A few specimens (A) have only 2 pairs of papillae on segments XIX and XX ; and in one individual (i) only a single pair of them on segment XIX is present. The papillae have a transverse oval shape and are situated just in front of the circle of setae, which sometimes are pushed from their place ^). The spermathecae lie in segments VI and VII ; in most specimens there are more than one pair in each segment, I) For an account of their structure, as also for more details of the inter- nal anatomy, see my paper ,.on the earthworms of the Dutch Scientific Expedi- tion to central Borneo." Notes from the Leyden JVIuseuixi, Vol. XX- ON PERICHAETIDAE, 209 and usually the number of them at the right side is not the same as that at the left. The largest number, observed in segment VI, was 29: at the right side 17, at the left 12; it was in a worm from Sintang, with only a single pair of papillae. In a couple of specimens I found only two spermathecae in this segment, one on each side. In segment VII the number of spermathecae usually is larger than in the preceding; in one specimen T observed 30 of them, 15 at the right and 15 at the left side. The smallest number I met with was 3 on each side. It is not always in the largest specimens that the greatest number of sper- mathecae is to be found. A specimen, 300 mm. long, showed a single pair of them in segment VI, while in segment VII there were 12, at the right side 7, at the left 5; on the contrary one individual, 115 mm. in length, had in segment VI five spermathecae, 3 at the right and 2 at the left, while the following segment showed 5 pairs of them.

Two specimens, one of which carrying eggs, from the Sugut river , North Eastern Borneo, collected by Mr. Prakke. Both specimens have the same size and measure about 18 millim. from the tip of the rostrum to the end of the telson ; they are somewhat smaller than the Atjeh speci- mens described 1. c, the largest of these being 28 millim. long. Though both individuals are only provided with the larger chelipede , they ought , however , to be referred to the variety quoted above. The rostrum which reaches about to the distal extremity of the first joint of the antennular peduncle, scarcely extends backwards to the middle of the cephalothorax ; the upper margin of the interocular com- pressed portion of the rostrum appears slightly concave. In both specimens the basal joint of the outer antennae is armed with a very small spine on the anterior margin of the inferior surface, not visible when looked at from above. In both individuals the larger hand fully agrees with that of the Atjeh specimens , and this is also the case with the carpal joints of the 2ud pair of legs. The five joints of the carpus of these legs are respectively 1,9 — 0,76 — 0,44 — 0,44 and 0,7 millim. long, the first joint is a little shorter than the four following together and 2'/2 times as long as the second joint; the hand, measuring 1,6 millim., is as long as the third , fourth and fifth joint together. The following legs also agree with the Atjeh-specimens. The globular eggs of the female have a diameter of 0,5 mm. lerseke, June 1898, ^Notes from tlie Leyden jMuseuna, Vol. XX.
