MELVILL : ON LATIRUS ARMATUS AD. 11'/ 



The true Latirus cariniferus Lm. from the Pacific is quite distinct. 

 In this the shell slopes away immediately below the very prominent 

 median spiral angulation at the last whorl. Indeed the abundant 

 L. polygonus will remind one more of the typical L. armatu^ but the 

 whole texture being so different, no one could for an instant sup- 

 pose that they were identical. 



California, given by Adams as the habitat of the Cumingian type, 

 must be erroneous. I see no reason for altering the sequence of this 

 species in the catalogue of Latirus and Peristemia, with L. distinctus, 

 L. cariniferus r and L. polygomis as nearest allies.

 The "Report on Mollusca," by R. Standen (pages 218-226) contains a list of 

 sixty- two land and freshwater species, together with many interesting notes on 

 habitats and distribution of some of them, e.g. Geoitialacus maculosus ; Helix lamel- 

 lata; H. sericea, a very local shell in Ireland; H. caper at a, the occurrence of which 

 is interesting, because of its being one of the four Helices belonging to the section 

 Xenophila, specially quoted by Dr. Scharff in his " Origin of the European Fauna," 

 as not occurring in this particular district of Ireland ; Succinea oblonga, taken in 

 considerable numbers under seaweed, a singular habitat for this excessively rare 

 species ; and Lir?ina , a involuta. An account is also given of an expedition to the 

 Cromaglaun, with descriptions of the Crincaum Lake and its remarkable inhabitant, 

 about both of which many erroneous statements have been made. A reprint of Mr. 

 Standen's paper is sent to each member of the Conchological Society, along with 

 the current issue of the Journal].
