he should address himself. The deliberate use of " Fischer " for " Fischer de 

 Waldheim" cannot be right, as it would lead readers to believe that Dr. Paul 

 Fischer was intended ; the contraction could serve no useful purpose, as there is 

 plenty of room at the close of the paragraph in which it occurs. The name 

 of " Fischer '' occurring after the family name on the page before would increase 

 the confusion. If it were allowable to contract the name, then the full name 

 should be printed' before the contraction and not after. If readers will refer to 

 the use of '■'■ Actcon'''' (ser. i. part 59, p. 153), they will see that it is not referred 

 to as a quotation, as Mr. Pdsbry states in error; the full sentence is, "This 

 species is the type of the genera Aiteon, Tornatella, and Speo." Really 

 Mr. Pilsbry shoukl not expect me to be lidtter acquainted with his works than he 

 is himself. I shall not carry on this controversy further, for, as he wisely 

 remarks, Ciii bono'i It is a pity that this did not occur to him earlier. — E. R. S.

MALACOLOGY IN GENERAL. 



Taylor, John W. — A Monograph of the L. and F. M. of the British Isles. 

 Part i., pp. 1-64. I ])1., 138 figs. ; Leras : Taylor Bros., Oct. 1894. 



A work on the L. and F. Mollusca of the British Isles, which would incor- 

 porate the latest views of all schools of workers, has long been wanted, and that 

 the present publication, when complete, will form a valuable aildititm to the 

 literature of the subject, there can be little doubt. 



Part I deals with the History, Classification, Nomenclature, Synonymy, and 

 Shell. 



The views of most authors are set forth in a fair and concise manner, a feature 

 which we trust will continue to characterise the work. Even should there be 

 much in the systematic portion to which we shall be unable to assent, or however 

 adversely we regard the same, we feel the amount of time and energy that has 

 been expended, the care and patience with which material has been collected, and 

 the manner in which the same is now arranged, well merit the support of all who 

 are interested in this section of the mollusca. Mr. Taylor is to be congratulated 

 upon the style of production and illustration, which leave nothing to be desired. 



We trust we shall not have to wait long for future parts, but that the support 

 given to the present issue will stimulate the author to a speedy publication.

STRUCTURE AND DEVELOPMENT. 



Babor, J. F. — Uber den Cyclus der Geschlechtoentwicklung der Stylommato- 

 phoren. Verhandl. d. Deutsch. Zool. Gesell., 1894, pp. 55-61, figs. i-io. 

 This interesting paper details some very valuable observations upon the variation 

 of the generative organs of certain molluscs. A large number of cases are reported 

 where either the male or female organs were absent, e.g., those of Bietrix 

 {H. pomatia), Giard [Pteroirackica), Fewkes and Barrois (Paliidina), Collinge 

 {H. aspersa and Arion inlermedius), Simrolh ( / 'itiina and Agr. Levis).
