The specimens from Stat. 47 and 311 are young and bleached, in consequence their 

 identification is not quite safe. The largest specimen from Stat. 164 is very characteristic, but 

 the violet colour of the base is wanting; the brown lines of the base are less numerous or 

 even nearly wanting in young specimens. It appears that if the figures of Kobelt, I.e. PI. 15, 

 fig. 3 — 6, are correct, they belong to some other species. This species seems to be variable, at 

 least I have seen some specimens agreeing in many respects, but differing in other particulars; 

 I describe them as: 



var. ornata n. var. PL XI, fig. 11. 



Stat. 33. Bay of Pidjot, Lombok. 22 M. Mud, coral and coralsand. 12 Spec. 



Differing from the type in being more painted with yellowish-brown. The spotted band 

 below the suture is broader; base with six white lirae, with small brown spots; the interstices 

 of the lirae are spirally striate, as in the type. 



Though at a first look differing considerably from the type, the sculpture is really the 

 same, so I have not ventured to describe a new species on the slight differences recorded 

 above. The majority of the specimens is still young. 



5. Turritella (Haustator) sp. 



Stat. 299. Buka-bay, South coast of Rotti-island. 34 M. Mud, coral and Lithothamnion. i Spec. 



This specimen is still very nearly allied to var. ornata of the preceding species, especially 

 by the colour-pattern of the base, but the whorls are strongly flammulate, and the articulated 

 band below the suture, if present at all, is not conspicuous. 



6. Turritella (Toraila) concava v. Martens.

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



Only one young specimen has been collected, it exactly agrees with the description, 

 however I can find no traces of the small reddish dots, which I have detected on a fossil 

 specimen from Celebes (Samml. des Geol. Reichsmus. Leiden, Ser. I, Vol. VIII, p. 190) which 

 were also present, though much less conspicuous on a typical specimen, received for comparison, 

 from the Zool. Museum in Berlin. 



Moreover a number of small specimens has been collected, they are probably young, but 

 could not be identified, as the upper whorls of adult specimens are nearly invariably wanting 

 and consequently cannot be used for comparison.
