HADRA. 281 



in the Proc. Linnean Soc. N. S. Wales, (2), vi, p. 321 (May 23, 

 1892). He includes as synonyms of GULOSA Gld. 1846, the fol- 

 lowing : H. coriaria Pfr. 1847, H. morosa, Morel. 1853, H. mona- 

 cha Pfr. 1859, H. mastersi Cox 1864, H. scotti Cox 1864. 



To this list I am disposed to add H. lessoni PFR., Symbolse iii, p. 

 71 (1846) ; Conchyl. Cab. p. 363, pi. .138, f. 9. 10.? REEVE, 

 Conch. Icon. f. 754. Not H. lessoni of Cox (Mon. Austr. L. Sh.), 

 of Pilsbry, (Manual vol. VI) or of authors generally,=if. semini- 

 gra Morelet. The H. duralensis Cox, is probably a stunted form of 

 gulosa. 



H. JERVISENSIS Q. & G. 



H. gulosa intergrades by imperceptible degrees with H. grayi 

 Pfr. (Manual vi, p. 130), as Dr. Cox has written me, and demon- 

 strated by a set of shells showing the intermediate stages (no. 62,413 

 of the Academy collection.) 



The synonymy of the grayi type of shells is believed by my friend 

 Dr. Cox to be as follows ; H.jervisensis Q. & G. 1832, H. gilberti Pfr. 

 1845, H. grayi Pfr. 1848, H. exocarpi Cox 1868, H. bednalli Braz. 

 1871. I am in full agreement with this synonymy. Dr. Cox also 

 suggests that the lighter, thinner forms, corneovirens Pfr. 1851, and 

 mulgoce Cox 1868, may prove to fall into this series. 



It may not be out of place to correct here the references given 

 under H. grayi Pfr. in the text (p. 130). They should stand as 

 follows: Helix (GRAY, New Zealand, t. 1, f. 8, 9.) 



PFEIFFER, Symbolse ad Historiam Heliceorum, iii, p. 68, (1846). 

 Helix grayi PFR., Monogr. Hel. Viv. i, p. 134 (1848.) 



The reference given by Pfeiffer to Gray relates to some unpub- 

 lished plates sent to him by Gray. These plates have never, I 

 believe, appeared in print. The name " grayi" dates from 1848.
