ALLEN: NOTES ON CHIKOPTEEA. 49 



The skull of No. 6803, <J adult, measures: greatest length, 20.4; basal length, 

 17; palatal length, 10.3; interorbital constriction, 5.5; zygomatic breadth, 14; 

 mastoid breadth, 12 ; mandible, 14. S ; maxillary tooth row (exclusive of incisors), 

 7 ; mandibular tooth row (exclusive of incisors), S. 



By way of comparison, I give the measurements of an adult female, P. iuklii, 

 No. 6979, from Delhi, India, collected by Mr. Thomas Barbour: head and body, 

 76; tail, 50; forearm, 56.5; thumb, 9.2; third finger, 99 ; fifth finger, 69 ; tibia, 

 22; foot, 11.5; calcar, 20; ear, 16.5. Skull: greatest length, 22.2; basal 

 length, 18; palatal length, 11; interorbital constriction, 5; zygomatic breadth, 

 15 ; mastoid breadth, 12.5 ; mandible, 16 ; maxillary tooth row (exclusive of 

 incisors), 8 ; mandibular tooth row (exclusive of incisors), 9. This specimen 

 is rather small, as the average length of the forearm of eight other specimens from 

 the Koolloo Valley and Delhi, India, is 60 mm. (59-64). In addition to the 

 greater size of the skull and teeth of kuhlii, the occipital crest shows a much 

 stronger development than in temminckii. 



Pachyotus castaneus (Horsfield). 



A single specimen, female adult, No. 6933, from Buitenzorg, Java, I have pro- 

 visionally referred to this species, although it seems a trifle larger tiian specimens 

 from the Malay Peninsula. It was collected by Mr. Thomas Barbour, and by him 

 presented to the Museum. Bonhote (Proc. Zool. Soc. London, ]900, p. 192) 

 gives the forearm measurement of continental examples as from 49 to 52 mm. 

 (average 50.7), and states that the color is a uniform chestnut all over, not lighter 

 below. Our specimen is somewhat larger than these measurements indicate, and 

 the dorsal fur, iu alcohol, is distinctly darker than that of the ventral surface. A 

 series of this bat from Java might show that the insular animal is a distinct species. • 

 The measurements of No. 6933 are as follows. External measurements : head 

 and body, 64; tail, 58; ear, 13.5; forearm, 55.6; thumb, S; 3d finger, metacar- 

 pal 52.5; 1st phalanx, 19; 2d phalanx and tip, 19; 4th finger, metacarpal, 52; 

 1st phalanx, 15 ; 2d phalanx and tip, 11 ; 5th finger, metacarpal, 47-5 ; 1st pha- 

 lanx, 10 ; 2d phalanx and tip, 8.5 ; tibia, 22 ; foot, 9.5 ; calcar, 16. 



Skull: greatest length, 21.3; basal length, 17.5 ; palatal length, 10.7 ; inter- 

 orbital constriction, 5.4; zygomatic breadth, 14.5 ; mastoid breadth, 12.5 ; man- 

 dible, 15; maxillary tooth row (exclusive of incisors), 7.5 ; mandibular tooth row 

 (exclusive of incisors), S.5. 



Chalinolobus gouldi (Gray). 



An old female, No. 745, from Hobertstown, Australia, lacks the small upper 

 premolar on both sides, and thus shows an interesting parallelism with the related 

 African genus Glauconycteris, in which these teeth are now permanently lost.
