QUARTERLY CHRONICLE. 217 
Annelid is certainly a very useful deus ex machind, but since 
he has never been seen, nor anything like him, the appeal to 
his powers is rather an unsatisfactory way of accounting for 
a phenomenon. No Annelid has at present been described 
which bores a gallery in shells or limestones, with the single 
exception of a vague reference by some authors to such a 
habit in a species of Leucodore. Mr. Hancock further con- 
tends that the dendritic form of the Cliona-galleries is unlike 
anything done by worms. The connection between the 
Foraminifera and Spongiade through the excavating Clione 
is of considerable importance. Mr. Hancock points out the 
great similarity of the form of the sarcode substance in the 
one and the other, and alludes to the genus Carpenteria, a 
Foraminifera which exhibits spicules as further illustrating 
their relationship—Cliona celata, Gorgonioides, Northumbrica, 
vastifica, corallinoides, gracilis, Howsei, Alderi, lobata, 
vermifera, Mazatlanensis, globulifera, and Carpenteri are de- 
scribed and their characteristic spicula figured—the last four 
being new foreign species. 
‘* Remarks on the Falces and Mazille of Spiders,” by 
John Blackwall, F.L.S. “ Much careful investigation is yet 
required,” says the eminent arachnologist, “‘ to complete our 
knowledge of the various minute appendages connected with 
the external organs of spiders and of the purposes to which 
they are subservient.’ Miss Staveley recently described in the 
Annals a row of minute teeth on the outer margin of the 
maxillee of numerous species of spiders which induced Mr. 
Blackwell to examine the species of Mygalide, in the expec- 
tation of finding a somewhat different arrangement. ‘The 
inferior surface of the base of these organs were found to be 
thus armed in Mygale, Cteniza, and Atypus. Figures of 
these structures are given. The late Mr. Richard Beck 
accumulated some valuable microscopic observations on 
spiders and acari, which might perhaps be published with 
advantage. 
June.—‘ Notes on Pelonaia corrugata,” by W. Carmichael 
McIntosh, M.D., F.L.S.—This paper contains a description 
of the anatomy of this interesting tunicate molluscoid, illus- 
trated with a good plate. Dr. McIntosh communicated a 
short description of the same animal to Section D at Notting- 
ham, when he considered the creature as new. 
** On the Dentition of the Common Mole,” by C. Spence 
Bate, F.R.S.—The investigation of the early condition of the 
teeth of mammalia is most important as bearing on the homo- 
logies of those teeth; and in such researches the microscope 
has necessarily to be largely used. Mr. Bate’s observations
