fact all the other genera belonging to this suborder are wanting, 

 although their absence is unexplained*. 



Page 6. In looking at the catalogue of Sepiola we miss at least 

 three names which have been proposed for so-called species of the 

 genus, and three species are assigned to '■'■Pels " (whoever that may 

 be) which were described by Pfelfer. 



Proceeding to the Heteropoda, p. 13, we find Janthinn, Reduzia, 

 and Macgillivrariia included in this group. The two former genera 

 have long since been properly classed with the Ptenoglossa among 

 the Gastropoda, and the species of Macc/iUivra)jia are known to be 

 merely the larval forms of Gastropods. None of the shell-less 

 Heteropods are quoted, and the lists of the Atlantidae and Carinarice 

 are full of omissions, both in the species and the synonymy. Five 

 species, at least, of the latter are wanting, and about the same number 

 of Atlanta, besides which the names of three species are wrongly 

 spelt — namely, gihba, heliconokles, andQuoyi, which should be gihhosa, 

 helicinoides, and Qaoyana respectively. 



Proceeding to the Gastropoda we may take as a test of accuracy 

 the first page (p. 57) of the familj^ Pleurotomidce. This extensive 

 group occupies no less than forty pages. In examining p. 47 we 

 have noticed that ten names are omitted which should have been 

 included in the alphabetical list of species between abbreviata and 

 alterum ; nor are they to be found under any of the other sections- 

 of the family on the subsequent pages. 



Thinking that possibly the work might have improved in the later 

 parts we have examined one genus, Cyliclma, p. 621. Here again 

 gx'eat omissions occur, over thirtt/ described species being unrecorded ! 



The names of localities are greatly abbreviated, and in some 

 instances almost beyond recognition ; for instance, many might fail 

 to guess what was meant by C. b. sp., Puert Porter, M. pers., Dieg. 

 Srz., C. Espbg., &c. 



With regard to the references which are given it may bo pointed 

 out that several of them are ridiculous and others are scarcely 

 recognizable or only to be guessed at. 



As a specimen of the ridiculous kind we would mention " Ad. gen." 

 This abbreviation occurs throughout the volume and of course refers 

 to the work by Messrs. H. and A. Adams on the Genera of Recent 

 MoUusea. As, however, merely lists of the names of the species are 

 given under their respective genera we gain no information by turning 

 to the work mentioned. 



Samples - of those which are scarcely recognizable or only to be 

 guessed at are, "Petit," "A. Ad. Moll. Jap."t, " Mrts. Peitr.," 

 " Shell Afr. Sow.," " Proc." $, " Grdlr. Vz.," " Binn. Amer.," " Tapp. 

 C," " Brgt. Etud. Pal.," '* Beau 17, G.," &c. &c. 



* The fact of these forms possessing no shells may account for their 

 omission. 



t A, Adams has never published any work entitled 'MolluscaJaponica;' 

 but some of his papers on Japanese shells in these ' Annals ' are probably 

 referred to. 



X This reference is given to A. Adams, Forbes, Jeffreys, and may refer 

 to the Proc. Zool. Soc, London.
