compressed, and reaches the plane of the anterior border of the single 

 molar. A lobule in the position of the basal convolution of other Phyl- 

 lostomines lies between the first and the third plates, and resembles in 

 general appearance a separate endoturbinal. The second endoturbinal 

 is small and concealed. The third and fourth plates are in general 

 appearance much as in other Phyllostomines. The lobes of the first and 

 third endoturbinals are conspicuous. 



Carollia brevicaiula (Plate V. figs. 3, 5). — The first ectoturbinal is 

 inflated, with no trace of the concavity marking the plate in the Vesper- 

 tilionidte. It is two thirds the length of the first endoturbinal. The 

 last-named plate is narrowed anteriorly, but not acuminate, since the tip 

 is truncate. Its lower border is concave. The lobule at the summit of 

 the plate is broader in front than behind, and equals the free portion in 

 length. The third plate is concealed. The foui-th is of the same size 

 and shape as the foregoing. The fifth is triangular in form, open be- 

 neath, and presents the appearance of having a large lateral convolu- 

 tion equal in length with the main plate. The maxilloturbinal is 

 rudimentary and free from the ethmoturbiual. 



Lonchoglossa. — The general plan in this genus is as in other Phvl- 

 lostomines. The ectoturbinal is minute, compressed, not more than one 

 half the length of the first endoturbinal The latter is thiu, straight, 

 with a long falciform lobe, which is concave inferiorly. The basal lobule 

 is well developed, and lies at the lower border of the median surface of 

 the ethmoturbiual. The remaining eudoturbinals as in other Phyllosto- 

 mines, but less obliquely inclined. 



PhyUostoma hastatum (Plate V. fig. 2). — The foramina of the septo- 

 turbinal and the ectoturbinal surfaces on the encranial aspect form a 

 continuous arch. The depression for the main plate is large, and the 

 space behind it is occupied by numerous openings arranged without 

 apparent order. 



Schizottoma. — The ectoturbinal is moderately inflated, but less so 

 proportionally than in Dermanura. The narrow and acuminate first 

 endoturbinal projects about one third of the length of the ectoturbinal 

 Its lobule is inconspicuous. The second endoturbinal is concealed, and 

 presents a Blightly inflated upper border. The third plate 

 a large anterior lobule, which is convex forward. The parte are 

 contiguous upon the median surfl 



Maerotut Waterhourii. — The ectoturbinal is small, a little Less than 

 one half the length of tlic first endoturbinal. Its upper border La hori- 

 zontal, and its lower OOncave. The extreme tin of the lobule extends as
