XIV. — Descriptions of two new Sponges from the Philippine 

 Islands. By H. J. Caetee, F.R.S. &c. 



The two following Sponges, obtained at Cebu, one of the 

 Philippine Islands, by Dr. A, B.Meyer, and now the property of 

 the British Museum, are herewith described at the request of 

 Dr. J. E. Gray, pending their further description and future 

 illustration elsewhere. 



1. Meyerina (nov. gen.) claviformis, Gray. 



Specif c character. — Sarco-spiculous. General form long, 

 conical, cucumber-like, slightly bent upon itself. Colour now 

 (that is in its dried state) light sponge-yellow. Cylindrical 

 at the base, where the yellow colour ceases, and the structure 

 is extended by bundles of long, colourless, glassy spicules, 

 which were continued downwards for several inches into the 

 sandy mud in which the sponge grew, while they pass upwards 

 in an oblique network, longitudinally, to the middle of the 

 body, whence they are continued on, by repetition, to terminate 

 at the apex in short naked tufts round the cloacal orifice of 

 the sponge, like those at the root, to which they thus bear a 

 miniature resemblance. Surface even towards the base, be- 

 coming angular in the middle third by the projection of long 

 ridges, which, uniting longitudinally, leave lozenge- shaped 

 intervals as they gradually subside towards the apex. Vents 

 chiefly on the ridges, in large circular network, and here and 

 there in the intervals, which, on the other hand, are occupied 

 by a small rectangular network, in the interstices of which are 

 the pores. Internal structure rigid, reticulate, largely canalo- 

 areolar, especially towards the surface, interwoven with the 

 longitudinal spicules before mentioned, and surrounding a long, 

 fusiform cloacal cavity, which commences about four inches 

 from the base, and, increasing gradually in size to about the 

 middle of the body of the sponge (where it is an inch in dia- 

 meter), then diminishes again towards the apex, where it ter- 

 minates in an orifice about one sixth of an inch wide ; per- 

 meated on all sides by tlie canals of the areolar structure, which
