Hab. Island of Ticao, Philippines (under stones at low

Easily recognised by its style of painting. 



Species 52. (Mus. Cuming.)

Species 53. (Mus. Cuming.) 



Eicinula recurva. Ricin. testd abbreviato-ovatd, mea 

 gibbosd, utrinqae attenuatd, basi recurvd, anfractib

 superue unicarinatis, infra tenuiter liratis; luteo-aura, 

 tid, fascid albidd medio cingulatd. 



The recurved Eicinula. Shell shortly ovate, gibboi 

 round the middle, attenuated at each end, reciu-v( 

 at the base ; whorls concentrically plicately ribbe 

 ribs rather broad, close-set, a single keel round tl 

 upper part, finely ridged beneath ; yellowish orang 

 encircled round the middle with a wliite band. 



Hab. Lord Hood's Island, Pacific Ocean ; Cuming. 



Species 54. (Mus. Cuming.) 



Eicinula echinata. Ricin. testd ovatd, utrinque atiei 

 uatd, longitudinaliter plicato-costatd transeersim pen 

 liariter liratd, liris angustis tubulosis, costas super pit.

 vatis ; albidd, punctis crocato-rufis seriatim pictd. 



The prickle-armed Eicinula. Shell ovate, attenuate

Of a character totally distinct from that of any specie 

 that have preceded it ; the varieties of seidpture and ai 

 rangement of colour in the semi-Eicinuloid series of thi 

 genus are truly interesting.
