ART. 19 BATS OF THE GENUS TADARIDA — SHAMEL 7 



TADARIDA INTERMEDIA, new species

 Goldman.

Diagnosis. — Skull and teeth smaller than in T. mexicana; greatest 

 length of skull 15.5-16.2 mm. instead of 16.2-17.8 mm. Ear extends 

 to end of nostril when laid forward. 



Teeth. — The molariform teeth are smaller in transverse extent than 

 those of T. mexicana or T. brasiliensis. The length of the maxillary 

 tooth row is 5.5-6.0 mm. instead of 5.8-6.5 mm. and 6.0-6.6 mm., 

 respectively, in these two related forms. 



Measurements. — Type: Head and body, 52.4; tail, 27.6; tibia, 12.8; 

 foot, 8.8; forearm, 45.0; third metacarpal, 44.6; fifth metacarpal, 26.4; 

 thumb, 6.5; ear from meatus, 16.0; ear from crown, 12.8; ear width, 

 15.2; total length of skull, 15.8; zygomatic breadth, 8.5; interorbital 

 breadth, 3.8; occipital depth, 5.8; breadth of braincase, 7.8; basal

Specimens examined. — Fourteen from the following localities: 

 Chiapas, Valley of Comitan, 11 alcoholics including the type; Guate- 

 mala, Jacatlenango, 3 alcoholics. 



Remarks. — This bat is not different from T. mexicana in outward 

 appearance or external measurements, but the skulls run smaller in 

 all their measurements, their uniformly less size being at once notice- 

 able when specimens are laid out in a series. The range is inter- 

 mediate between T. mexicana and T. brasiliensis, but the characters 

 are not.
