 : TREHBLINO Olive. Shell somewhat elongately 

 i-yliudrical, whorls sliglitly contracted posteriorly 

 and before the middle, apex exserted, front colnmel- 

 lav plaits rather strong ; carnelion-white, sometimes 

 three-banded with dark brown, and painted longi- 

 tndinaUy with blue-clonded streaks very much con- 

 fused, sometimes dark brown throughout, interrupted 



here and there with carnelion-white, columella and in- 

 terior of the aperture whitish, generally tinged with 

 flesh-red.

This well-known species has mostly a carnelion-rouge 

 tinge, but not a positive red interior as in O. erythrostoma. 

 The specimens figured at 6 c, d, e, represent the ordinary 

 state of it, densely clouded throughout with blue-shaded 

 streaks and obscurely three-banded with dark-brown 

 blotches. In Fig. a, b, the shell is entirely brown except 

 in a few scattered patches, in which state it passes into 

 the variety represented in the preceding plate at Fig. 5 c. 

 This last variety, of which M. Duclos represents a cha- 

 racteristic specimen at PL 11. f. 8 of his monograph, is 

 generally of larger size and of more solid growth, pre- 

 senting almost sufficient character to be regarded as a 

 tUstinct species.
