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 E vale a, A. Adams. 



Testa elongato-conica, subturrita ; spira elata ; anfractibus transversim 

 sulcatis aut striatis. Apertura ovata, antice producta ; plica parie- 

 tali transversa, valida. 



The fact of many species of this genus being 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. Meaoe, 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 Rev. 

 M. J. Berkeley, and pronounced by him to be fungous matter.
