22 Mr. R. H. Meade on the Occurrence of 
riam rotundato ; apertura ovali, antice subproducta; plica parie- 
tali conspicua, obliqua. 
Hab. Mino-Sima; 63 fathoms. 
Subgenus Evarea, A. Adams. 
Testa elongato-conica, subturrita ; spira elata ; anfractibus transversim 
sulcatis aut striatis. Apertura ovata, antiee producta; plica parie- 
tali transversa, valida. 
The fact of many species of this genus bemg transversely 
grooved or striated is, I consider, of sufficient importance to 
keep them distinct, as peculiarities of surface and sculpture are 
great aids in determining species.

V.—On the Occurrence of Spiders and their Webs in Coal-pits. 
By R. H. Mzapz, F.R.C:S. 
EXTENSIVE masses or layers of web-like tissue have often been 
noticed in some of the northern collieries, and they have generally 
been considered as the mycelium of a fungus; in fact, some 
years back, a filamentous cottony substance, obtained in some 
of the Durham coal-pits, was submitted by Mr. Hunt (of the 
London Mining Record Office) to the examination of the Rey. 
M. J. Berkeley, and pronounced by him to be fungous matter.
