handle, from the Latin cafuhis. Var. giblosa is more swollen in 

 appearance, and var. stricta has the sides more compressed or 

 restricted. 



The next genus Acroloxus (from two Greek words which, in combin- 

 ation, mean slanting at thetop)has the species lacustris inhabiting lakes. 

 Its var. 7iioquifiiana was so named by Bourguignat, after the great French 

 conchologist, Moquin-Tandon. 



In the genus Lhn/icEa the species auriadaria is named from 

 the supposed likeness of its large mouth, with widely reflected 

 outer lip, to the human ear. The var. reflexa has the outer lip more 

 reflected than usual. The species peteger, i.e., wandering, a good 

 name for a shell found practically over the whole of the Eastern 

 Hemisphere ; or it may be named from its almost amphibious habits. 

 Var. obtusa, blunt. Stagnaliformis is like Liiiivaa stagvalis in shape. 

 Vulgaris is a name that should be given, if at all, to the type. 

 Maritima=-{oviv\di near the sea. Microstoma, i.e., small mouth. 

 Diaphaiia, i.e., transparent, from the thinness of the shell. Pida, 

 painted, i.e., marked spirally by alternate bands of brown and white. 

 Labiosa, i.e., with a large lip, expanded and reflected, so as to resemble 

 auriadaria. Buruetii is named after its discoverer, a Newcastle 

 naturalist. Involuta is supposed to convey the information that the 

 spire is enveloped by whorls. The species falustris (marsh-inhabiting) 

 has the vars. corva, i.e., a crow (not that corvus has a female form), 

 from its dark purple colour : ohesa, i.e., fat ; iincta, i.e., dyed, from 

 the mouth being purplish; lanawsa, i.e., with flattenings, depressions, 

 and protuberances, making lacuuce or gaps in the surface. 



Z. truiicahila, i.e., somewhat truncated. Var. veniricosa, from 

 ventruj/i, a belly, having the whorls tumid. 



L. stagnalis, i.e., inhabiting swamps. Var. vatiegafa, i.e., with 

 whorls varigated with white growth markings. Leptolimnxa is named 

 from AeTTTos trim. Glabra, i.e., smooth. Aviphipeplea, i.e., covered 

 with a mantle — when young. Glutitiosa indicates that to the touch 

 it is glutinous from the expansion of the mantle over the shell. Var. 

 mucronafa, i.e., pointed like a sword. 



Planorbis is a coined compound, a non-classical word, meaning a 

 flat coil. Its species cortieus is horn-coloured. Gyraulus is from the 

 Greek words for round and a tube. Its species albus has the var. 

 sulcata, i.e., furrowed ; C7'ista has the ridges of the epidermis exagger- 

 ated into crests, while the var. Icevigafa (which should be spelled with 

 an ^ not an ce) is smoothed, i.e. without ridges ; dilatatus, i.e., expanded 

 (as to its mouth). Cariiiatiis, i.e. keeled, with its var. discifortnis, i.e. 

 disk-like, which is flatter ; uwbilicaius, i.e., with an umbilicus ; 

 rhonibea, i.e. four-sided, refers to the appearance of a section of the
