141,092. Collected January 15, 1905, by Dr. W. L. Abbott. Original 

 No. 3944. 



Diagnosis. — Like Taphozous melanopogon, but decidedly larger, with 

 much larger skull. Lower lip more distinctly grooved above and in 

 front. 



Color. — Head, nape, and fore part of back, bister; posterior upper- 

 parts darker, slightly mixed with blackish-brown, the underfur every- 

 where broadly buffy-white. Throat and breast dark blackish-brown; 

 belly and sides light drab, mottled with pale drab-gray, the underfur 

 broadly buffy-white as on back. 



Skull and teeth. — Skull like that of Taphozous melanopogon, but much 

 larger, especially broader and with higher braincase. Teeth larger. 



Measurements of type. — Head and body, 93; tail, 23; forearm, 65. The 

 forearm of an adult 9 topotype in alcohol measures 66. 5. Skull of type: 

 Condylobasal length (without prem axillary), 19.4; total length (without 

 premaxillary), 20.6; zygomatic breadth, 13.3; breadth braincase, 10.6; 

 mastoid breadth, 11.4; interorbital breadth, 6.0; postorbital breadth, 5.1; 

 length upper tooth row, entire, 9.3; mandible, 16.2; mandibular tooth 

 row, entire, 11.3. 



Remarks. — Externally this species agrees with T. melanopogon in every 

 character except the large size and the more pronounced lip grooves. 

 Doctor Abbott has written in his field catalogue: " These two bats were 

 brought me by a native who said he caught them in a large hole or cave 

 in the rocks by the sea shore." The paratype is preserved in alcohol.
