Many of the characters of this species are implied in the foregoing 
generic description. The constriction marking the union of two ad- 
jacent cells is deep and the general shape strongly moniliform. The 
stems are usually straight, but sometimes much contorted, and a 
few instances have been noted in which branching occurs. The size 
of the individual segments is rather small, seldom exceeding 10 mm. 
The osculum is large. The ostia are also rather large and spout- 
like. They are few in number and rather uniform in size and distri- 
bution. It is difficult to determine the exact number, but there seem 
to be six or eight, arranged transversely at nearly equal intervals, 
usually along the median line. Frequently the arrangement of these 
structures is sufliciently systematic for those of several consecutive 
chambers to form longitudinal rows. 
If there is little doubt that this is the same form which Mr. Beede 
identified as Amblysiphonella prossert in the work cited above, there 
can be no question that it belongs to a different species as well as to 
a different genus from the form described by Clarke.

MA ANDROSTIA, new genus. 
This type consists of subcylindrical, stem-like, more or less bent, 
occasionally branching bodies. A central tube-like cloaca traverses 
the entire axial portion. The rather thick walls are intersected by 
vermiform chambers, which communicate with the surrounding me- 
dian through numerous circular ostia, and with each other and with 
the cloaca by means of frequent though irregular apertures. The 
partitions between adjacent chambers, between the chambers and the 
cloaca, and between the chambers and the exterior are of the same 
character, apparently structureless and imperforate. 
Though both sponges are at present preserved as carbonate of 
lime, Cwlocladia, in strong contrast with Meandrostia, retains its 
spicular mesh-like structure, while the walls of the latter are to all 
appearance solid and structureless. In this respect J/wandrostia 
agrees with /eteroca@la, and also in the general plan of construction, 
consisting, as it does, of separate though irregular chambers. 
Heterocalia is so related to other genera which are usually looked 
upon as belonging to the Calcispongie that it can pretty safely be 
regarded as belonging to the same group. On account of its re-
