Cristigibba T.-C., Ann. Mus. Civ. Genov. xix, 1883, p. 161. 



With the general appearance of Planispira, these shells differ in 

 having a crest or swollen ridge behind the lip, or a strong swelling 

 on the base immediately behind the constriction preceding the lip. 

 The spire is flat, a little concave in the middle. Type P. eorniculum. 

 (See pi. 12, fig. 13-15, C.macgregori Hedley.). 



The group is characteristic of New Guinea, but a few species range 

 as far north as Ceram, Batjan, and even Borneo and Sumatra.
