498 Mr. K. Andersen on Hippositleriis diaclema 



Remarks. — 8 adult and 5 j'oung specimens *, from all the 

 above-named islands of the Philippine gronp, have been 

 examined. They all agree closely in cranial and external 

 characters. In the general size of the skull and teeth, as well 

 fis in the anteorbital width, there is scarcely more than an 

 average difference between this and the foregoing race, but 

 the forearm is longer. Such at least is the case in all the 

 specimens just referred to. But one adult example, from 

 Zamboanga, collected by A. Everett, is quite extraordinarily 

 small, the forearm measuring only 77"5 mm., the tail 35'8 

 (in all the others 43-54). The gap between this specimen 

 and the whole of the other series (the young individuals 

 not excejjted) is so great that I can hardly believe it to be- 

 long to the same form. We find in the Philippines, in the 

 same island, Bhinolojjhus arcvatiis and subrvfvs, two distinct 

 species differing in no important respect but size ; in Java 

 Rh. minor and aciiminatus, differing much in the same way ; 

 in the Solomon Islands H. d. oceanitis and IJ. dinops, a small 

 and a large representative of the same type of bat ; it is 

 therefore not improbable that in the Philip})ines there occurs 

 a small and a large form of H. diadema. But to decide tl is 

 more ample material is necessary. 



Technical name. — The type of " Rhinolophvs p'iseus" 

 was from S. Matheo Cave, Luzon f- The figure (half 

 natural size) gives a tolerably good representation of a 

 //. diadema ; the dimensions, as derived from this figure, are 

 quite as in the Philippine series examined by me. 'J he fur 

 is stated to be " ganz aschgrau,^^ which is certainly not the 

 case in any specimen or any race of diadtma I have seen; 

 the ears are far too small, the supplementary leaflets not 

 indicated. Notwithstanding these discrepancies there can, 

 in my opinion, be no doubt as to the identification of 

 Meyen^s species. 



Ilipposideriis diadema pullatus, subsp. n. 



Diagnosis. — Anteorbital width 9-2-9'5 ; upper teeth IPS- 

 12-5. Forearm 75-5-81. 



Details. — The anteorbital width is slightly larger than in 

 the foregoing forms, but there is no sharp line of separation, 

 the maximum of gi'iseus being equal to minimum oi pullatus. 



* Five of these thirteen specimeus were kindly sent me for inspectiou 

 by Mr. Gerrit S. Miller, Washington.

 p. 316), the type specimen has been lost.
