about one half the height of the cell; edge with a raised rim, with 
numerous small notches in its inner edge, each ending in a pore; surface 
of the coral scattered with minute simple pores and vesicular tubercles. 
The structure of the cell of this genus is very particular ; for in 
Fungia, Cary ophy Ilia, and many of the allied genera, the cell is com- 
pletely divided into several cells by numerous radiating plates. In 
Porites the internal parietes of the cells are furnished with longitudinal 
laminae, and the centre is filled up with perpendicular columns, whilst in 
Pocillopora the cells have the longitudinal fold of the last genus but the 
centre is simple and hollow, and in this the internal parietes of the 
cells are smooth, with the centre half filled by a long protuberance, and 
instead of the laminae round the parietes the margin is rounded, and 
furnished with pores, each communicating with the cell by a slit. 
This coral has very little affinity with the genus Oculina, with which 
it has been always placed, as that genus has the same kind of cell as the 
Caryophyllcei; it must be nearly allied to Stylophora, but the centre column 
is not produced beyond the surface of the coral, which is also differently 
formed. Two species may be referred to this genus. 
Oculina rosea. Rose coloured, with the cells scattered on the whole 
surface. 
Oculina Jiahelliformis. Pale yellowish red. The coral fanshaped, 
the branches compressed, with the cells forming series along each side. 
In Oculina hirtella the laminse of the star occupy nearly the whole of 
the cells, while in Oculina virginea and its allies the cells are very deep, 
the laminse funnel-shaped, leaving a cavity, while another Oculina in 
the Museum has very shallow laminse like those of Poccillopora,

Hardwiche's Rhinopome. Rhinopoma Hardwickii. Dark brown, 
rather paler beneath; tail longer than the body, more than two-thirds 
free. Inhab. Bengal. Gen. Hardwicke’s collection; the collection of 
the British Museum. 
Gen. IsTioPHORUS, Pit-nose Bat. Vesper tiUonid(E. 
The nose-plates extended behind into a lanceolate leaf, with a deep pit 
in the centre of the front part between the nostrils ; tragus lanceolate, 
toothed; interfemoral membranes only margining the legs; tail none; 
rest like Megaderma. 
Pale Pit-nose Bat. Istiophorus flavescens. Pale yellowish, the hairs 
long, irregular and silky. Length of body and head 1 9, of fore-arm bone 
18 lines, expanse 10 inches. In the collection of the British Museum. 
Gen, Hipposideros. 
Nose plate like Rhinolophus but shorter in front with rounded nostrils 
and with an elevated cross ridge behind, over which is produced a reflexed 
nose-leaf attached to the cross rib by three longitudinal membranaceous 
ridges. This genus is separated from Rhinolophus in not having any 
longitudinal caruncle, and in the nose-leaf being more complicated. It 
contains eight species, two of which have a pore on the forehead, as
