 Stat. 142. Laivvui, coast of Obi-Major. 23 M. Mud. i Spec. 



The specimen from Stat. 66 is very young and accordingly of somewhat doubtful 

 identification, that from Stat. 142, though not adult, is easily recognizable. Pilsbry considers 

 this species to be a variety of the preceding species, but as the sculpture in the two specimens 

 I could compare, is rather different, I have kept them separated. The sculpture of the base in 

 this species, consists of beaded spiral lirae, with comparatively broad interstices, about twice as 

 broad as the granules, with radiating and faint spiral sculpture, while in incrassalns, the granules 

 are much larger and either nearly touch the neighbouring row, or the lirae are separated by 

 interstices, which are considerably narrower than the lirae. 



6. Trochus (Lamprostoma) sp. 



Stat. 109. Pulu Tongkil, Sulu-Archipelago. 13 M. Lithothamnion-bottom. i Spec. 



This specimen is too small for identification. I think it does not belong to one of the 

 preceding species. 



7. TrochiLS (Lamprostoma) ticbiferus Kiener.

Stat. 250. Island Kur. Reef, i Spec. 



The only specimen agrees better with Reeve's figure of T. concinmis, than with the typical 

 one of Kiener, copied by Pilsbry ; as however according to Fischer, Kiener's specimen was 

 not adult and the species is very variable, I have applied Kiener's older name.

 Stat. 301. Pepela-bay, East coast of Rotti-island. 22 M. Lithothamnion-bottom. i Spec. 



Both specimens though young and broken, are recognizable by the characteristic contour 



and sculpture.
