Stat. 66. Bank between islands of Bahuluwang and Tambolungan, South of Saleyer. 8 M. 



Dead coral, Halimeda, Lithothamnion. 4 Spec. 

 Stat. 90. i°i7'.5N., n8°53'E. Celebes Sea. 281 M. Coral, sand and stones. 1 Spec. 

 Stat. 99. North-Ubian. 16 — 23 M. Lithothamnion-bottom. 6 Spec. 



Varying much in sculpture, one of the young specimens from Stat. 66 has the nodules 

 at the suture much more developed than those from Stat. 99.

Stat. 104. Sulu-harbour, Sulu-island. 14 M. Sand. 1 Spec. 



Probably only a variety of the preceding species ; the only specimen is young and conse- 

 quently the identification rather uncertain ; in accordance with the figure of Reeve, the spire is 

 more acuminate than in C. articulata.

Kobelt, whose figures are not very characteristic, especially not in the shape of the canal, 

 says: " Aus dem indopacifischen Ocean ist sie meines Wissens noch nicht bekannt geworden, 

 wenn nicht etwa Cerithium graniferum Pease hierher gehort". Dunker (Index Molluscorum 

 maris Japonici, p. 108) has recorded the species from Japan, and has observed specimens with 

 brown lines in the interstices of the lirae, more rarely whitish ones, agreeing with Philippi's 

 figures. Previous to this record is that of Lischke (Japanische Meeres-Conchylien, Band I p. 72, 

 Band III p. 49); v. Martens (Moll. Mauritius p. 280) quoted by Kobelt, prefixes an "I" to 

 the species, meaning that it lives also in the Indian Ocean (Nicobaren, Ceylon, Malaischer 

 Archipel). In the majority of the specimens, the interstices of the lirae have distinct brown lines, 

 where they are wanting, this seems to be caused by fading, in dead specimens. The canal, if 

 intact, is by no means so straight as in Kobelt's figures, so I have left the species in the 

 genus Clava = ] T crtagus.
