WEINKAUFF. Martini-Chemn. Conch Cab. Ed. II, Vol. V, Oliva, p. 30, PI. 1, fig. 9, 10; 



PI. 9, fig. 4, 7, 8, 10. 

 TRYON. Man. of Conch. Vol. V, p. jj, PI. 21, fig. 97 — 99; PI. 22, fig. 100 — 5. 



Stat. 231. Amboina. Reef. 10 Spec. 



Stat. 272. Dobo, Aru-islands. Reef. 3 Spec. 



The specimens from Dobo agree with Lamarck's description of the colour: "flavida" 

 "un fond jaunatre", those from Amboina are mainly darker. 



7. Oliva octavia Duclos. 



Duclos. Chenu. Illustr. Conch. p. 29, PI. 28, fig. 21, 22. 



WEINKAUFF. Martini-Chemn. Conch. Cab. Ed. II, Vol. V, Oliva, p. 103 [neostina pars). 



TRYON. Man. of Conch. Vol. V, p. 78, PI. 22, fig. 15 (neostina var.). 



Stat. 231. Amboina. Reef. 2 Spec. 



Perhaps this species belongs to one of the allied forms, but as the two specimens are 

 easily recognizable, I have kept them separate. 



8. Oliva laevis Marrat. 



Marrat. Thes. Conch. Vol. IV, Oliva, p. 26, PI. 20, fig. 330, 331. 



WEINKAUFF. Martini-Chemn. Conch. Cab. Ed. II, Vol. V, Oliva, p. 121, PI. 32, fig. 1—4.

Stat. 133. Lirung, Salibabu-island. Up to 36 M. Mud and hard sand. 1 Spec. 



A small specimen. Weinkauff and Tryon have much doubt about the validity of this 

 species and really its characters are far from prominent, but I do not know to which species 

 I should unite it and so have kept it separate. 



9. Oliva maura Lamarck. 



LAMARCK. An. s. vert. Ed. II, Vol. X, p. 608.

PI. 2, fig. 3, 4, 6, 7, 8, 9; PI. 5, fig. 17. 

 TRYON. Man. of Conch. Vol. V, p. 78, PI. 23, fig. 21—25; PI. 1, fig. 5; PI. 34, fig. 54.

with dead shells. 1 Spec. 

 Stat. 304. Lamakera, Solor-island. 16 AI. Coral and Sand. 1 Spec. 



One of the specimens from Stat. 131, dark grey with black ziczac-lines may be ascribed 

 to var. f:ilminans Lam. (1. c. p. 610).
