ENQUIRY COLUMN. 
Can any member tell me the derivation of Gzb7manica?—LIoNEL E. ADAMS. _ 
The name Gibz/imanica clearly refers to some mountain, ‘‘ gibel” being the Arabic “* Jebel,” 
and recalling the occupation of the Saracens. I find ‘‘ Gibelliformi ” a hill close to Palermo, and 
“‘ Gibellina” a larger hill in the western corner.of Sicily.—H. R. M. 
All the specimens of /ivifara wivipara which I have taken, amounting to many hundreds, 
have contained young. As it is stated that the animals are dicecious it would appear that the 
males must be very rare. Can any reader inform me whether any season or any mode of capture 
is more likely to be favourable for taking them than another?—R., C; 
Can any member tell me whether Acicu/a ¢ineata (Drap). is viviparous or not?—W. J. FARRER.
