Stat. 315. East of Sailus Besar, Paternoster-islands. Up to 36 M. Coral and Lithothamnion. 1 Spec. 



The specimen is still very young, uniformly red. 



4. Aquillus (Lampusia) gemmatus Reeve.

KÜSTER. Martini-Chemn. Conch. Cab. Ed. II, Triton, p. 220, PI. 61, fig. 7, 8.

Stat. 47. Bay of Bima, near South fort. 55 M. Mud with patches of fine coralsand. 1 Spec. 



Stat. 240. Banda. Reef. 1 Spec. 



Stat. 304. Lamakera, Sulor-island. Reef. 1 Spec. 



The specimens from Lamakera and Bima are quite typical, corresponding to Reeve's 

 figures 60a and b. That from Banda is yellowish, with a few brown bands, calling in mind 

 some varieties of the preceding species, but there the dark colour occupies the interstices of 

 the spiral lirae, whereas in the specimen of gemmatus the dark colour runs over the lirae. In 

 sculpture I see no difference with the other specimens. 



5. Aquillus (Turritriton) laóiosus Wood, var. orientalis Nevill. 



Nevill. Journ. Asiat. Soc. Béng. Vol. 43, 1874, p. 29. 



KÜSTER. Martini-Chemn. Conch. Cab. Ed. II, Triton, p. 261, PI. 69, fig. 8.

Stat. 60. Haingsisi, Samau-island. Lithothamnion-bank. 1 Spec. 



Stat. 240. Banda. 9 — 45 M. Black sand, coral. Lithothamnion-bank. 1 Spec. 



Stat. 285. South coast of Timor. 34 M. Lithothamnion. 1 Spec. 



Some of the specimens are too young, to decide with certainty if they belong to the 

 variety oi-ientalis Nev., as however the larger specimens are not doubtful, I think they ought 

 to be all placed here.
