Chamalycaeus celebensis (E. von Martens, 1891) Fig. 10A

Alycaeus celebensis E. von Martens, In: Weber, 1891: 217-218.

Alycaeus (Chamalycaeus) celebensis - Kobelt 1902: 354.

Type locality.

"Celebes: Luwu".

Material examined.

Luwu, Celebes, M. Weber, ZMB/MOLL 44738 (photographs of a shell [possible syntype] were examined).

Remarks.

Protoconch elevated, no spiral lines visible, although the suture is filled with dirt and the photographs are not of high quality. R1 with strong widely spaced, ribs with a fine spiral striation; R2 with denser, straighter ribs, although this part of the shell was somewhat corroded. This species is placed in Chamalycaeus due to the colourless shell and biogeographic location. A closer examination of the protoconch would be important to rule out its affinity with Metalycaeus , although the occurrence of that genus in Celebes would be surprising.
