""" Of f , NATURAL **• HISTORY CHICAGO, U. S. A. FEBRUARY 12, 1931 PRINTED IN THE UNITED STATES OF AMERICA BY FIELD MUSEUM PRESS BATS FROM POLYNESIA, MELANESIA AND MALAYSIA BY COLIN CAMPBELL SANBORN tfl The following report is based upon the collections of bats made by the Crane Pacific Expedition of Field Museum of Natural History, by the Whitney South Sea Expedition of the American Museum of Natural History, and by Dr. William Mann for the Museum of Comparative Zoology. Included also are two specimens presented by John T. Zimmer. The combined collections contain 783 specimens, representing nineteen genera and fifty-three species and subspecies. Of these, nine genera and thirty-seven species belong to the Megachiroptera and ten genera and sixteen species to the Michrochiroptera. The greatest value of this material is, perhaps, what it has added to knowledge of distribution, for there are specimens from many islands never collected on before and new records from various other islands. Distribution, and especially seasonal distribution, is un- doubtedly governed by the food supply. Of seasonal distribution very little is known. That distribution is, in some cases, probably very limited is shown by the material from the Solomon Islands where twenty-one forms were taken. The Whitney South Sea Expedition has collected bats in the Solomons in every month except May, and from seventeen islands visited secured fourteen forms, ten of which are in its collection only. The Crane Pacific Expedition visited three islands in April, securing five forms of which four are not in the other collections. Dr. Mann collected six species on three islands and three of these were taken only by him. Kulambangra was the only island visited by but one of the expeditions, and no two collectors visited any island during the same month. If there was a wider distribution of the various forms there should have been more than four species duplicated by two of the expeditions. There is still much to be learned about the Megachiroptera besides distribution. Many species are known only from a type or from a few specimens. In some species there appears to be a wide range in color, and series of certain forms are needed to fully establish their status. A systematic survey of the Pacific islands would go far toward a better understanding of this group. 8 FIELD MUSEUM OF NATURAL HISTORY— ZOOLOGY, VOL. XVIII In the nine years since the publication of Mr. Knud Andersen's Catalogue of the Chiroptera, twenty-five new forms of fruit-bats have been described. A list of these is given at the end of this report. Two new species are described in this paper. The Crane Pacific Expedition was in the field from January to August, 1929. Most of the 587 bats taken were collected by Frank C. Wonder, the mammalogist of the expedition. These were secured on twelve of the islands visited by the expedition between the Fiji Islands and the Philippines. Some species are represented by large series. Eighteen of the forms taken are not represented in the other collections and three are described as new.1 The Whitney South Sea Expedition has been in the field for many years but primarily in search of birds. Its collection of 211 bats is the richest in forms and is from the widest territory. I have exam- ined specimens taken between 1923 and 1930, collected by Hollo H. Beck, F. P. Drowne, Hannibal Hamlin, and others. This collection contains nineteen forms not represented in the other collections and two have been described as new. The collection of Dr. William Mann from the Solomon Islands is small, containing but six species. Three of these, however, are not represented in the other collections although they are from islands visited by the other expeditions. I have examined twelve specimens from this collection, which was identified by Dr. G. M. Allen. I am indebted to the authorities of the American Museum of Natural History for the privilege of examining their material and for permission to include it in this report. My thanks are also due to H. E. Anthony, Curator of Mammals, and to the members of the department of mammals for their interest and cooperation. I wish to thank Dr. Glover M. Allen of the Museum of Comparative Zoology for the same favors in connection with Dr. Mann's collection. John T. Zimmer generously presented two specimens from New Guinea and the United States National Museum loaned one for comparison with them. The spelling used for the names of the various islands has been taken, wherever possible, from An Index to the Islands of the Pacific, by William T. Brigham (Mem. B. P. Bishop Mus. Ethnol. and Nat. Hist., 1, Mem. 2, Dec. 1900). 'Besides the bats covered in this report, the Crane Pacific Expedition secured specimens of Artibeus j. jamaicensis and Macrotus w. waterhousii in Haiti, and Myotis 7i. nigricans and Saccopleryx b. bilineata in Panama. 1931 PACIFIC ISLAND BATS— SANBORN LIST OF LOCALITIES AND SPECIES TONGA ISLANDS Uanukuiliahaki Island Pteropus tonganus SAMOAN ISLANDS Olosenga Island Pteropus tonganus Pteropus samoensis Tutuila Island Pteropus samoensis Savii Island Pteropus samoensfe Upolu Island Pteropus samoensis Manua Group Pteropus tonganus Tau Island Emballonura semicaudata FIJI ISLANDS Namena Island Pteropus tonganus Nairai Island Pteropus tonganus Yasawa Island Pteropus tonganus Vana Levu Island Pteropus tonganus Oyalau Island Pteropus tonganus Viti Levu Island Pteropus tonganus Notopteris macdonaldi Emballonura semicaudata Taviuni Island Pteropus nawaiensis NEW HEBRIDES ISLANDS Aurora Island Pteropus eotinus Lopevi Island Pteropus eotinus Mau Island Pteropus bakeri Nguna Island Pteropus bakeri Malo Island Miniopterus australis Hipposideros cervinus Malekula Island Pteropus geddiei Pteropus eotinus Elephant Island Pteropus geddiei Espiritu Santo Island Pteropus geddiei Pteropus eotinus Hipposideros cervinus Efate Island Pteropus geddiei Pteropus bakeri Hipposideros cervinus Penticost Island Pteropus geddiei BANKS ISLANDS Ureparapara Island Pteropus banksiana SANTA CRUZ ISLANDS Vanikoro Island Pteropus geddiei Pteropus tuberculatus Tapoua Island Pteropus geddiei Santa Cruz Island Pteropus geddiei Pteropus nitendiensis Hipposideros tricuspidatus Fenualoa Island Hipposideros cervinus DUFF GROUP Masurers Island Pteropus geddiei MATEMA (SWALLOW) ISLANDS Nupani Island Pteropus geddiei 10 FIELD MUSEUM OF NATURAL HISTORY — ZOOLOGY, VOL.

(four examined), 1916. This species has been recorded from Fauro and Guadalcanar in the Solomons but this is the first instance of its occurrence on Ysabel. The forearms are 74 and 76 mm. in two males and 68.2 in a female. P1 is present on both sides in all the skulls. Andersen found that the formula for the palatal ridges in the one specimen examined was 3+4+1 but added that "some slight individual variation may occur." In the larger male the fourth ridge is divided in the median line making the formula the same. In the other male and in the female the formula is 4+3+1. Andersen found the same variation in R. leachi. Pteropus hypomelanus luteus K. Andersen. Pteropus hypomelanus luteus K. Andersen, Ann. and Mag. Nat. Hist., (8), 2, p. 362, 1908.

TERRITORY OF NEW GUINEA: Marienberg, forty miles up the Sepik River (F. M. No. 31858), juv. male, May 17, 1929. This specimen was compared with the types of Pt. h. luteus and PL h. vulcanius by Dr. W. H. Osgood, who found that it differed in many respects from both of them. It is, however, very immature. While this specimen does not have the buffy or dull whitish wash on the chest and belly, nor the intermixture of the light buffy or whitish hairs on the back, as in vulcanius, this is no doubt due to its immaturity. Its main difference is in its black throat, which in vulcanius is dull buffy. Dr. Osgood also found that the teeth appeared to be wider in proportion to their length than the teeth of either luteus or vulcanius. With but one immature specimen, however, these two differences hardly warrant the naming of another subspecies in a group already so full, and especially as Vulcan Island is only about fifty miles in an air line from Marienberg.

Pt. colonus has been known previously from Shortland and Alu Islands from two specimens. The present series of colonus and 1931 PACIFIC ISLAND BATS— SANBORN 13 solomonis agree closely with the original descriptions in color and measurements and vary in but one respect. Andersen gives the length of m1 in colonus 4.4-4.5 mm. and 5.2 in solomonis; this tooth in this series of colonus measures 3.8 (very worn)-4.5 and in solomonis 4.3, 4.5, and 4.8.

This series greatly increases the range of Pt. geddiei as known by Andersen, and shows geddiei to be a wide ranging form of fairly uniform color with a forearm of from 150 to 170 mm. When I first examined this large series I came to the conclusion that Pt. geddiei MacGillivray should be a synonym of Pt. vanikorensis Quoy and Gaimard. After a conversation with Mr. Ellis Le G. Troughton of the Australian Museum, who has not only made a thorough survey of Vanikoro Island but who has lately examined the type of vani- korensis in Paris, I agree with him that vanikorensis is really a synonym of Pt. tonganus Quoy and Gaimard. The reasons for this conclusion will be given by Mr. Troughton in a future paper. Pteropus sepikensis sp. nov. Type from Marienberg, forty miles up the Sepik River, Territory of New Guinea. No. 31855 Field Museum of Natural History. Adult male. Collected May 22, 1929, by Frank C. Wonder. Orig. No. 303. Diagnosis. — A member of the melanopogon group and about the size of Pt. melanopogon but much darker throughout. Size very large, forearm 204 mm. Color. — Top and sides of head, from in front of eyes to in front of ears, belly, flanks, lower breast, and chin covered by very dark brown hairs, some of which have light, almost straw-colored tips, most prominent in center of belly, lower breast, rump, anal region, and sides of head. There are a few silver hairs throughout the dark brown parts. The bases of all the hairs from a line in front of the ears and down the top of the neck to the back, are close to Cream Color. The tips of the hairs of the mantle and the whole length of the crinkly hairs on the sides of the neck are close to Ochraceous Orange. Some of the crinkly hairs are scattered across the throat and mingle with the light-tipped hairs of the lower breast. Back and tibia naked. The under side of the membrane along lower forearm covered with dark brown hairs. Skull. — Long and narrow with a well-developed sagittal crest extending the full length of the braincase. Coronoid heavy and sharply ascending. Teeth long and narrow. Measurements. — Forearm 204; pollex, total length c. u. 76; pollex metacarpal 18.5, first phalanx 44; second digit, metacarpal 111, 1931 PACIFIC ISLAND BATS — SANBORN 15 first phalanx 22, second and third phalanges c. u. 22; third digit, metacarpal 132, first phalanx 101, second phalanx 153; fourth digit, metacarpal 130, first phalanx 85, second phalanx 83; fifth digit, metacarpal 139, first phalanx 64, second phalanx 58. Ear 24, flat 16; lower leg 93; foot c. u. 61; calcar 29. All measurements from dried skin. Skull: Total length to gnathion 90.9; palation to incisive foramina 45.5; front of orbit to tip of nasals 32; width of brain case at zygomata 29; zygomatic width 49; width across m1 externally 23.2; lachrymal width 19; width across canines externally 17.9; postorbital constriction 12.2; width of mesopterygoid fossa 9; width between p*-p4 internally 14.8; orbital diameter 17.1; mandible length 73; coronoid height 35.8; upper teeth c-m2 35; lower teeth c-m3 40.7. Remarks. — The type, and only known specimen, is very old. The teeth are worn smooth and there are no characters left in them. They are, undoubtedly, very much as in true melanopogon which, from Andersen's measurements, is nearly the same size as sepikensis. Its very different color will readily distinguish sepikensis from the other members of the group which are found in the Amboina group, Bunda Islands, Timor Laut, Key, and Aru Islands, all west of New Guinea, and one species on Johanna Island, Comoros, between Madagascar and the mainland. The type was brought in by a native and other specimens were seen later but were flying so high that they were out of the range of a twelve gauge shotgun. In the skull of the type the zygomatic arch shows that it had been broken in three places but had healed and grown together again. Pteropus cognatus K. Andersen. Pteropus cognatus K.

No. 79941, 79947), male, female, Sept. 7, 1927, (F. M. No. 31562), male, April 17, 1929. This species was formerly known from Alu and Bougainville Islands. This series shows a fairly constant color pattern throughout but the males have a slightly lighter back than the females. As Andersen suspected, the females do not have a glandular neck tuft, nor does a young male in the series. The specimen from Choiseul Island has an extra tooth in the lower jaw behind molar three. The distribution of the rayneri group in the Solomon Islands as it is now known is: Pteropus cognatus, San Christoval 4, Ugi 1. Pteropus rayneri, Guadalcanar 8, Malaita 1.

PL bakeri was compared by Thomas with anetianus and unfortunately not with eotinus. Baker (Ann. and Mag. Nat. Hist., 1928, (10), 2, p. 295) quotes Thomas as saying: "My Pt. eotinus, from Espiritu Santo, may be subspecifically different from the type specimen from Maewo; but 18 FIELD MUSEUM OF NATURAL HISTORY— ZOOLOGY, VOL. XVIII there are not sufficient specimens from Maewo to determine the point." The collections under consideration contain one topotype of eotinus which is immature and agrees rather closely with the descrip- tion of the paratype; also the skulls have been mixed and the skull may not belong to this specimen. There are also one topotype of bakeri in alcohol and two other specimens, one in alcohol and one skin with skull, from islands close enough to the type locality to be considered typical bakeri. There are six specimens from Espiritu Santo, Malekula, and Lopevi Islands, which, while they show marked color differences from the description given for eotinus, also show a wide range of color in themselves. The skulls, however, do not show any marked differences which could not be attributed to age. In view of the limited material for comparison of the three species already de- scribed, it seems better to refer these last six specimens to eotinus until better material can be secured, rather than add another species of this group to the New Hebrides. Pteropus banksiana Sanborn. Pteropus banksiana Sanborn, Am. Mus. Nov., No. 435, p. 1, 1930. BANKS ISLANDS: Ureparpara or Bligh Island (A. M. No. 79986), male, Nov. 16, 1916. Skin in alcohol, skull removed. Pt. banksiana is the most northern representative of the samoensis group and is also its smallest member. It is about the size of anetianus but has a shorter forearm, 117.5 mm., and is of an almost uniform shade of brown. The type is the only specimen known. Pteropus tuberculatus Peters. Pteropus tuberculatus Peters, M. B. Akad. Berlin, p. 393, 1869. SANTA CRUZ ISLANDS: Vanikoro Island (A. M. No. 79955, 79959), male, female, Sept. 24, 1926, (A. M. No. 79896), female (ale.), Sept. 21, 1926, (A. M. No. 79898), juv. (ale.), Aug. 25, 1926. These are the only specimens of this species in the United States. Besides the few specimens in Paris, there are eight in the Australian Museum collected by Troughton in 1926 (Rec. Aus. Mus., 1927, 15, p. 355). So far the species is known only from Vanikoro Island.

Formerly woodfordi was known only from New Georgia and Guadalcanar Islands. Pteropus mahaganus sp. nov. Type from Tunnibuli, Ysabel or Mahaga Island, East Central Solomon Islands. No. 31563 Field Museum of Natural History. 20 FIELD MUSEUM OF NATURAL HISTORY — ZOOLOGY, VOL. XVIII Adult male. Collected April 17, 1929, by Frank C. Wonder. Orig. No. 247. Diagnosis. — Similar to and about the size of Pt. scapulatus from Australia, but lighter in color. Skull with wider palate posteriorly and much larger m2 and m3. Front of orbit above anterior half of m1. Forearm 131.8 mm. to 143.6. Color. — Type: Back close to Tawny Olive of Ridgway, inter- spersed with dark brown hairs; mantle and foreneck Light Buff darkened by grayish bases of hairs; a narrow strip of Warm Buif on foreneck; well-developed neck tufts between Tawny and Russet; sides of face and chin sparsely covered with long dark brown hairs; throat Antimony Yellow; breast and belly Warm Buff. In the four other specimens, three males and one female, the back and rump is Prouts Brown, heavily intermixed with silver gray hairs, less so in the female. The mantle and upper parts are all darker throughout than in the type. Skull. — Type: Brain case deflected; rostrum normal, ascending rami of premaxillae heavy, sagittal crest low, coronoid weak, low and sloping, condyle of mandible on level of alveolar line. Palate wide anteriorly, its edge being nearly parallel. Teeth very weak and nar- row, being but slightly larger than in scapulatus, with the exception of m2 and m, which are much larger. Pt. woodfordi, although much smaller, also has these teeth larger than in scapulatus but smaller than in mahaganus. Upper incisors separated from each other by a space equal to i1; lower middle incisors separated by a wide space; i2 slightly larger than i1. Upper canines long with many grooves, an especially deep one on the anterior face reaching almost to tip, and a narrow internal basal ledge; lower canines with a very narrow internal basal ledge. P1 about the size of i2; px about the size of m2 ; m2 about twice the size of m3. One skull has an extra tooth, a mere spicule, on the right hand side behind m2. Measurements. — Skin of type (minimum and maximum of five specimens given in parentheses): Head and body 223 (201-223); foot 46 (43-48); forearm 143.6 (131.8-143.6); ear 23 (23-25).

Length m2 2 (1.7-2), width m2 1.7 (1.3-1.7); length m3 1.4 (1.2-1.4), width m3 1.2 (1.1-1.2). Remarks. — Pteropus mahaganus is the third member of the scapu- latus group, the other two being scapulatus from Australia and woodfordi from Kulambangra, New Georgia, and Guadalcanar Islands in the Solomons. It is distinguished by its very narrow cheek- teeth, wide palate, moderately long, rounded ears, and light-colored mantle. It has the largest m2 and m3 of the three members of the group. The type and four others collected with it have been examined. The type is the only adult specimen with a sagittal crest, the others being younger. They were shot at night feeding on young green coconuts. A poor skin without skull or sex (A. M. No. 79822), collected Jan. 9, 1928, on Bougainville Island, which has a forearm of 137.6 mm., is provisionally referred to mahaganus. Acerodon jubatus mindanensis K. Andersen.

All these specimens from Colombo Cave were taken with a few shots fired simultaneously. The roof of the cave was about sixty feet high and in the dark no idea could be gained of how many bats were hanging there. Besides those saved, the natives took some home to eat.

In an adult female skull, one of five removed from the Field Museum alcoholic series, p3 is in the toothrow and is visible from without, instead of being internal and in the angle between p1 and p4. Likewise p3 is less crushed between pt and p4. In a very young skull the molars are about half through and, on one side, the canine and p1 and p4 are just appearing in the upper jaw. In the mandible the incisors and mt have the greatest development. The specimens from Koragu and Nyomonga were found in pots, drums, and other utensils in the native houses. A few miles down the river at Marien- berg they were not seen. This seems strange when they were collected on Nissan Island, although the season might account for it. Myotis muricola (Gray).

Records of this species from New Guinea are few. Besides these two specimens there is one in the Australian Museum from East Cape, Port Moresby, collected by Kendall Broadbent in December 1878. Thomas (Ann. Mus. Geneva, 1897, p. 609) records twenty-seven specimens from Kamali, close to the mouth of the Kemp- Welch River, and one from Aroma, collected by Loria. These localities are east of Port Moresby near the coast. Mr. Zimmer's specimens compared with one from Lincoln, North Territory, Australia (U. S. N. M. No. 237973), are much smaller in both skin and skull measurements. A larger series might show some subspecific differences. Miniopterus australis Tomes. Miniopterus australis Tomes, P. Z. S.

Type from Marienberg, forty miles up the Sepik River, Territory of New Guinea. No. 31802 Field Museum of Natural History. Adult male. Collected May 17, 1929, by Frank C. Wonder. Orig. No. 284. Diagnosis. — Much larger and darker than typical M. schreibersii from Europe; the largest and daikest subspecies known. Color. — Upper parts uniform Mummy Brown of Ridgway and under parts close to Bone Brown of Ridgway. 1931 PACIFIC INLAND BATS— SANBORN 27 Measurements. — Skin of type (minimum and maximum of twelve skins and ten spirit specimens in parentheses) : Forearm 51.4 (48.4- 51.4). Skull of type (minimum and maximum of eleven specimens in parentheses): Condylo basal length 17 (16.5-17.1); zygomatic width 10.1 (9.7-10.1); upper toothrow, c-m2 7 (6.8-7.1); across m'-m1, externally 7.9 (7.6-7.9). Specimens examined. — Total twenty-seven, twelve skins, ten alcoholics, and five skulls only, all from the type locality. Remarks. — This appears to be the first series of these bats received from northern New Guinea. Dobson lists one specimen and Jentink (Nova Guinea, 5, liv. 2, p. 364, 1903) one. Jentink's speci- men, however, had a forearm of only 40 mm. so it may have been M. pusillus. The closest named form is M. s. blepotis Temminck from Java which has a forearm of 42-44 mm. Compared with a series from Nodoa, Hainan, China, questioningly called blepotis by Dr. G. M. Allen, magnater is darker, and the skulls average larger, the minimum measurements equaling the maximum in the series from Nodoa, but the forearms are the same. Its large skull and dark color will identify magnater. The specimens were collected by a native in a cave about ten miles from Marienberg. Kerivoula hardwicki (Horsfield).
