 Dr. Pilsbry contiuues the list of species of Urocoptis of Jamaica. Follow- 

 ing this the undermentioned subgenera and sections ai'e dealt with, viz., 



Sub-genus Autocoptis, Pils., dealing with the Haitian forms. Type U. 

 iiwiiilifera, Pfr. Subgenus Arangia, Pils. & Van. Type U. sowerbyana 

 Pfr. The variety montetoronis is new. Sub-genus Idiostemma, Pils. 

 and Van. Type U. uncata, Gundl. Section Maceo, P. and V. Type and 

 sole species U. interrupta, Gundl. Sub-genus Cochlodinella, P. and V. Type 

 U. poeyana, Orb. The variety lacteofhia from Cuba, is new. Sub-genus 

 Gongylostoma, Albers. Type U. elegcnis, Pfr. A key to the following sections 

 is then given : Fibricutis, Pils., Sectilutnen, P. and V., Esochara, P. and V., 

 Pyc7ioptychia, P. and V., Paracallonia, Pils., Callonia,Cr. a,nd Fisch., Liocal- 

 lonia, Pils. U. kumboldtiana, Pfr. variety peraffinis is a new variety from 

 Western Cuba. It is similar to U. kumboldtiana, but somewliat more solid, 

 less shining, and the striae are widely spaced, especially on the spire. U. 

 oligomestis is a new species from Cuba. It is near to U. saxusa, Poey, but 

 differs from that species chiefly by the mucli reduced median axial lamella.

Dimon, A. C Quantitative study of the effect of Environment upon the 



forms of Nassaobsoleta and trivittata from Cold Spring Harbour, Long 

 Island. Biometrika, 1902, vol. ii, pp. 24—43. 

 The authoress has studied in some detail the variation and correlation of 

 these two species of Nassa. She discusses the influence of density and stillness 

 of tlie water on depauperization. 



Hoyle, W. E Notes on the Type Specimen of Loligo eblanae, Ball. Mem. 



and Proc. ]\Ianchester Lit. and Phil. Soc, 1903, vol. 47, No. 9, pp. 10, i pi. 

 A a result of an examination of the type of this Cephalopod, described by 

 Robert Ball in 1841, Mr. Hoyle confirms the opinion, which liad been formed 

 by others as well as himself, that this species is not distinguishable from the 

 Todaropsis veranyi of Girard. The distinctive characters of the genus are 

 given, and of the Irish specimen as fully as its state of preservation permits, 

 accompanied by figures of some of the more critical parts, also a table of the 

 synonymy, witli references to the descriptions and figures.

 From an examination of the type specimens of this genus, Mr. Pace con- 

 cludes that the affinities are with the Mangilinae ; but so little is known as
