of South America, probably 'Surinam,' which may be con- 

 sidered as the type region of P. hastatus of modern authors. 

 Assuming that specimens from the Island of Trinidad and 

 eastern Venezuela (Cuidad Bolivar and Suapure) represent 

 this form, P. h. panamensis is readily distinguishable by its 

 much larger size. In six adult specimens two from Trini- 

 dad and four from near Cuidad Bolivar the skull ranges in 

 total length from 35-37 (36); in zygomatic breadth, 19.5- 

 20.3 (20); mastoid breadth, 18-19, an d one old male 19.6 

 (18.5); width of rostrum, 8.2-9 (8.7). In nine specimens 

 from the same localities the length of the forearm ranges 

 from 80-82 (81); third metacarpal, 73-76 (74.6), as com- 

 pared, respectively, with an average of 88 and 82.5 in P. h. 

 panamensis. 



The series of true hastatus includes both phases of colora- 

 tion, the red and the dark; the dark specimens are similar in 

 color to the panamensis series. 





 Phyllostomus hastatus cau/ae, subsp. nov. 



Type, No. 14473, $ (?) a d-, Cali, upper Cauca Valley, Colombia; 

 J. H. Batty. 



Larger than Phyllostomus hastatus panamensis, but apparently not 

 otherwise different. 



Type, deep rufous brown, lighter and more golden on shoulders, 

 and sides of neck; ventral surface lighter than back. Of nine other 

 specimens (topotypes) eight are in the red phase several are like the 

 type and others somewhat darker and two in the dark phase, or 

 very dark seal brown without rufous. 



Measurements (type, from dry skin). Forearm, 93 mm.; third 

 finger: metacarpal 84, first phal. 20, second phal. 42, third phal. 23; 

 tibia, 32; foot, 24; calcaneum, 21. Upper toothrow (c-m 3 ), 14.6. 

 In ten specimens the forearm measures 90-94 (92); third metacarpal, 

 82-86 (84.5), against 86-90 (88) and 80-83.5 (82.5), respectively, in 

 panamensis. 



The skulls are too imperfect to measure, all but one (a young adult) 

 lacking the occipital portion. The dentition in both jaws is slightly 

 heavier, and the rostrum is slightly broader than in panamensis, indi- 

 cating a considerably larger skull. 



Compared with true hastatus, the difference in size is 

 strikingly marked, the forearm being fully one eighth longer,
