28. Bulimulus (Pleuropyrgus) lima Reib. 



Habitat. — Chatham Island (Wolf). Rare; occurring with P. tcre- 

 bra; only two exani])les (letcctcd, one of tlicsc possibly a junior. 



Judjjiiif? by his figure, 1 should regard the above as a dwarfed or 

 iidohisecnit form of chemnitzioides. 



{{(■ibiscli observes tluit tiiis group, I'leiiropyrf/u.s, seems to be restricted 

 to (Jiiatham Island. With our present limited knowledge of the land 

 moUusks of the Galapagos group it would a])i>ear so, but much more 

 liglit is needed to make generalizations of any great value. 



29. Bulimulus (Pelecostoma) canaliferus Reib. 



Habitat. — (Ihatliam Island (Wolf). Abundant in moss at an ele- 

 vation of 1)00 toli,000 feet. Four mature individuals. 



This may prove to be a valid species; the figure is unsatisfactory; it 

 suggests relationshii) to rugi/era and may be a dwarfed variety of that 

 si)ecies. 



30. Bulimulus (Pelecostoma) cymatoferus licib. 



IIaihtat. — Chatham Island (Wolf). "Inunature examples" seem to 

 have been regarded as a sufficient foundation for this species, of which 

 the soft parts are unknown, and the genus must rest on shell charac 

 ters only. 



The above is figured in pi. ii, 7, of Eeibisch's pnper; it is Dall's Lep- 

 tinaria chathamcnsis,* a subgenus oi Stenoyi/ra in the family iStenogyridoe. 



II. BUI.IMINUS EbKMiberg. 



31. Buliminus (Rhaphiellus) achatinellinus Forbes. 



Habitat. — CJalii])agos ((-nming), Chatham Island (Wolf), on mossy 

 rocks at an elevation of !)00 to U,00() feet; api)arently rare; no good live 

 examples dete(;ted. R(;ibisch says the sole example figured differs in 

 several particulars from that given in Pfeiffer. 



II. PUPA l>r!ii)!iriiiiud. 



32. Pupa (Leucochila) munita li<ib. 



Habitat. — Albemarle Island (Wolf), "on ])uslie8 near the shore," 

 close to /'. Wolji, wliich is abundant in the province of Guayaquil, 

 Ecuador. 



33. Pupa (Leucochila) clausa h'eib. 



Habitat. — Indefatigable Island (Wolf). 



On bushes near the shore. Ueibis(;h implies that this is a more de- 

 veloi)ed form of /*. Wolji.
