regard any of the forms of the invertebrate animals as mature, 

 unless that form had been detected in the parent state. 



Dr. Gould gave verbal notices of a number of the Pro- 

 ceedings of the American Philosophical Society — also, no- 

 tices of Thesaurus Conchyliorum. No. 1, by G. B. Sower- 

 by, Jr. 



He gave the latter work high praise, particularly remarking 

 upon the excellence of the figures. In respect to the reduced 

 figures, all on the same page are reduced in the same ratio, so as 

 to give a correct comparative view. The genus Helicina was 

 remarked upon as having been much increased of late with new 

 species. Lamarck enumerated 12 ; J. E. Gray added 16 ; this 

 writer makes 77 ; and yet has mentioned none from the islands of 

 the Pacific, from which source, numerous species have recently- 

 been brought. About one third of the species found in the Boston 

 cabinets are not found in this work, showing how much the num- 

 ber of actual species is yet to be extended.
