straight below, with a tubercle and rim above, bordering and rendering narrow the sinus, and until 

 9 shorter and longer folds; interior of apertural margins more or less stained with reddish-brown. 



Alt. 13, lat. 6^3; apert. alt. sYo, lat. r/g Mill. 



Allied to the preceding species, but more ventricose, with much finer granular sculpture 

 and different colour; it is still more remote from L. spurca. The measurements are taken from 

 the largest specimen from Stat. 51 ; the largest one from Stat. 260 has a length of 9^0 Mill., but 

 otherwise agrees in every essential character ; the smallest specimen has a length of 8Y21 a breadth 

 of 3^5 Mill, and is consequently more slender. In colour it resembles some species oi Peristernia.

Stat. 47. Bay of Bima, near South fort. 55 M. Mud with patches of fine coralsand. i Spec. 



This specimen is a dead, somewhat worn shell of small size (length 5Y2 Mill.), its iden- 

 tification consequently a little doubtful.

Stat. 116. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. i Spec. 



The specimen from Stat. 116 and one from Stat. 114 have their normal length of about 

 6 Mill., the other one from Stat. 114, of 8 Mill, and approaches in this respect CI. spelaeodea Herv. 

 (Journ. de Conch. 1897, P- 9^, PI- 2, fig. 4); as the specimens are bleached, I cannot clearly 

 see the colour, but the whorls are more angular than in Hervier's figure, and agree in this 

 respect with that of Reeve.
