in the Manual of Concliology. It will therefore be seen that 

 much time must be devoted to this work, in order to keep the 

 collection of the Academy abreast of others able to purchase 

 freely. Among the more important accessions may be mentioned 

 a large series of land and fresh-water shells collected by Mr, S. N. 

 Rhoads in Florida and Mexico, a series of Samoan Opisthobranchs 

 collected and given by Mr. C. N. E. Eliot, and a valuable lot of 

 exotic slugs, given by the R^v. A. B. Kendig, adding greatly to 

 what is now by all odds the largest collection of slugs in America. 

 The collection made by Mr. Rhoads, obtained in exchange for 

 identification, contains the types of some twenty-five new species. 

 That of Mr. Eliot the types and figured specimens. 



Dr. J. C. Cox, Mr. H. Suter, Dr. H. von Ihering and others 

 have continued their gifts of foreign mollusks, while the American 

 series has profited by the sendings of about seventy -five persons, 

 among whom Rev. E. H. Ashmun, Prof. T. D. A. Cockerell, 

 Messrs. George H. Clapp and L. N. Frierson may be mentioned 

 as contributing material of especial value. 



The Conservator, in company Avith Dr. Montgomery and Prof. 

 Conklin, made a collection of marine invertebrates in Biscayne 

 Bay, Florida, and later made a vacation journey to the Great 

 Smoky Mountains. A very large collection of the mountain 

 mollusks was made, including some rare and new forms of exces- 

 sively restricted range. Mr. J. H. Ferriss has contributed a valu- 

 able series from mountain localities south of those visited by myself. 



The Conservator acknowledges valuable assistance received from 

 Mr. C. W. Johnson, of the Museum Committee, and has also 

 been aided throughout the year by Mr. E. G. Vanatta, Avhose 

 efficient Avork deserves high commendation.
