Manual of Conchology, Second Series, Pulmonata, part 42, by Henry 

 A. Pilsby, Philadelphia, pp. 55-144, pis. 14-25. 



In this instalment, the section Bulimus proper, is brought to a finish. 

 Rhiiius is also completed, while a fifth section Hyperaulax (created by Mr. 

 Pilsby in 1897 for B. ridleyi, E. A. Smith) is added to the four (given ante, p. 

 29), into which Mr. Pilsby breaks up his second division of the genus 

 BuUmulus, or those species " with nepeonic whorls sculptured with waved, 

 zig-zag, or irregular subvertical wrinkles, or with the wrinkles dislocated 

 and broken more or less into granules or a netted pattern." Furthermore, 

 the third division, in which the sculpturing of the nepeonic whorls is regular, 

 is attacked — the forms belonging to the division are geographically and by 

 general appearance divided into sub-genera, viz. — Protoglyptiis from Eastern 

 and Northern America, Trinidad, etc., Naesiotus from the Galapagos Islands, 

 and Orthotomum from Central and Northern Mexico, Lower California, and 

 Southern United States. The work on the first is finished, and the present 

 part breaks off during the consideration of Orthotomum.
