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

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

 lostomines lies between the first iiud the tbird plates, and resembles in 

 genei'al appearance a separate endoturbinal. The second endoturbinal 

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

 appearance much as in other Phyllostomiues. Tlie lobes of the first and 

 third endoturbinals are conspicuous. 



CaroUla hrevkauda (Plate V. figs. 3, 5). — The first ectoturbinal is 

 inflated, witli no trace of the concavity marking tbc ])late in the Vcsper- 

 tilionidse. It is two tliirds 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. Tlie fouiih is of the same size 

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

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

 tion equ:d in length with the main plate. The maxilloturbinal is 

 rudimentary and free from the ethmotui'binal. 



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

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

 half the length of the first endoturbinal. The latter is thin, straight, 

 with a long falciform lobe, which is concave inferioi'ly. The basal lobule 

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

 the ethmoturbinal. The remaining endoturbinals as in other Phyllosto- 

 miues, but less obliquely inclined. 



Phyllontoma hastatuin (Plate V. fig. 21. — 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. 



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

 proportionally than in Dermarmra. 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 slightly inflated upper border. The third ])late possesses 

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

 contiguous upon the median surface. 



Macrotus Waterhouaii — Tlie ectoturbinal is small, a little less than 

 one half the length of the first cndotinl)inal. Its U])per liorder is hori- 

 zontal, and its lower concave. The extreme tip of the lobule extends as
