248 ON THE GLOSSOPHAGINE. 
The single specimen of J/onophyllus which was available was that of a skin of an 
adult (No. 83347, 9°, U. 8. N. M.) obtained by exchange from the Berlin Museum. The 
genus is in close alliance with Glossophaga—closer, indeed, than any two genera of the 
group. The retention of the hypocone in the first and second upper molars, the presence 
of a keel on the symphysis of the lower jaw and absence of the vertical line in the inter- 
digital spaces, separate the two forms. Other characters if they existed unassisted by 
those just named would be those of relation and proportion. The presence or absence 
ot the calear could not be determined. 
Monophyllus redmani Leach. 
Auricle with blunt tip, scarcely emarginate on outer border. Wing membrane from 
basal third of the tibia: terminal cartilage of the fourth digit, spatulate. Marked rudi- 
ment of ascending process from the zygoma. Nose leaf, upper lip and membrane much as 
in Glossophaga truer. 
The auricle resembles G. truer nearer than G’. soricina. It is blunt at tip, scarcely 
at all concave on the outer margin. <A faint emargination is noted on the inner margin 
which may be exaggerated in the dried skin. The external basal lobe was everted by 
the method used in preparing the specimen. The parts do not differ from those studied in 
Glossophaga. The tragus is blunt, presenting two coarse sinuations at the outer side and 
two denticulations at the base. The nose leaf, upper lip and mentum almost precisely 
the same as in G. truei. No warts are anywhere present. 
Fur above is dark brown; the head, neck and shoulders a lighter shade than the 
back of thorax and lom. Examined with a lens, the fur has an admixture of fine gray 
hairs, which are more numerous on head, neck and shoulders than elsewhere. The fur 
beneath is gray and brown, about equally admixed. Both above and below the hair is 
unicolored. Sparse gray hairs extend below on arm to elbow and slightly over the endo- 
patagium. The legs are naked. 
There is no vertical line on the membrane of any of the interdigital spaces. The 
endopatagium exhibits a few coarse vertical lines. The fourth interdigital space is 
obscurely areolate. 
The skull was mutilated at occiput and posterior third of the base. It closely resem- 
bles Glossophaga. The fronto-temporal crest is more defined, while the fronto-maxillary 
inflation is less defined than in that genus. The posterior palatine notch, narrow. Seen 
from above, the posterior border of the infraorbital foramen appears as a blunt spine. A 
narrow but well-defined groove extends the entire length of the face, beginning at a 
foramen near the pretemporal ridge. The ascending process from the zygoma is 
greatly in excess of the same character in G'lossophaga. The external auditory opening
