ENQUIRY COLUMN. 
Can any member tell me the derivation of Azmalia, Cecilioides, and Gibilinanica?— 
Lione, E. ApAms. 
Amalia (Moqg.-Tand., Moll. France, p. 19, 1855) is given without derivation, but as it is 
a not uncommon feminine proper name, it was probably chosen in honour of some friend or 
relative. —— Cecilioides is from ce@cus, blind, the animals being blind and nocturnal. The 
name was altered to Cecilianella by Bourguignat (Rev. & Mag. Zool. (2), viii., p. 378, 1856), 
on the ground that Férussac’s name (spelt by him wrongly Cecz/zoides) being an adjective, was 
inapplicable as a generic name. It is an open question whether this is an adequate cause for 
change. Férussac presumably avoided Cecilia because it was pre-occupied in Amphibia, —— 
Gibilmanica is probably a Sicilian geographical term, but I have not yet succeeded in finding 
its whereabouts.—P.K.F.
