388 Mr. W. King on some Families and Genera of Corals. 
allowed me to examine during my short stay in London. This 
instance of a sexual glandular apparatus in the Cheiroptera does 
not however stand isolated, since the observations of the late 
Dr. J. Natterer have made us acquainted with a gland on the 
males of at least many species of Dysopes, provided with an open- 
ing, and situated on the throat.

XLITI.—Gn some Families and Genera of Corals. By Wit11aM 
Kine, F.G.S. France. 
Fam. CyatrnoruyLuipa, Dana. 
Gen. Polycelia*, King. 
A (?) simple Cyathophyllidia. Form conical. Walls solid. Pri- 
mary vertical plates converging to within a short distance of the 
centre. Secondary vertical plates reaching about half way to the 
centre. Transverse plates horizontal, at irregular distances from 
each other, and extending quite across the cavity. Chambers or 
lamellar interspaces capacious compared with those of other Cya- 
thophyllidias. Reproduction within the polypiferous cup. 
Type, Turbinolia Donatiana, King, ‘ Catalogue of the Organic 
Remains of the Permian Rocks of Northumberland and Dur- 
ham,’ p. 6. 
This genus differs from most Cyathophyllide in its struc- | 
tural characters ; but it appears to be nearest related to Cyatho- 
phyllum, taking as its type the (?) tri-areal C. plicatum of Gold- 
fuss, which is the first species described under the genus (vide 
‘ Petrefacta,’ pl. 15. fig. 12). 
Fam. FEnEsTELLip#”, King. 
Setting down as the type of Fenestella the F. antiqua of Lons- 
dale, it is proposed to place all those palzozoic genera in the pre- 
sent family agreeing with this genus in being reticulated, and 
having the cellules planted on a basal plate composed of vertical 
capillary tubuli as first discovered by Mr. Lonsdale. Besides the 
typical genus above-named, Fenestellide includes the Polypora 
and Ptylopora of Mr. M‘Coy, and the two genera next to be 
described. | 
Gen. Synocladiat+, King. 
A foliaceous or frondiferous infundibuliform Fenestellidia. 
Fronds consisting of numerous connected stems or ribs. Stems 
* Etym. zroAd’s, many ; KoiAos, a cavity. 
+ Etym. ody, with; «rddos, a branch.
