Referring to the paper on Pulex Penetrans formerly read 

 by him, Mr. Boyd also drew attention to two papers on the 

 Chigoe, or Jigger: Pulex Penetrans in the same magazine, 

 one by Waterton, the other a translation from Pohl and 

 Kollar's work, "Brasiliens vorziiglich lastige Insecten," which 

 give good descriptions of the ravages of these little pests, 

 but do not enter fully into anatomical details. 



Mr. Boyd showed under the microscope specimens of this 

 insect, and dissections of its oral appendages. 



Mr. J. Cosmo Melvill, M.A., F.L.S., read a paper entitled, 

 "A proposed revision of the species and varieties of the 

 subgenus Cylinder (Montfort) of Conus (L.)." 



After briefly enumerating the chief characteristics of the 

 large assemblage of Mollusca included in the genus Conus, 

 containing from 450 to 500 species, he pointed out that the 

 subgenus under discussion corresponded with the 17th and 

 last Section "Texti," of Weinkauff's classification of the 

 genus — adopted in the latest issued monograph, by Mr. G. W. 

 Try on, Junr,, of Philadelphia, in his "Manual of Conchology," 

 1884 



He illustrated his paper with specimens from his collec- 

 tion, which exhibited 35 of the 89 described forms. He 

 proposed that these should be divided into five groups, as 

 follows :— Conus (L.) § subg : Cylinder (Montfort).
