Stat. 60. Haingsisi, Island Samau. Reef. 1 Spec. 



The only specimen is very dark in the interstices of the lirae, which are yellowish-brown. 

 Hedley (Proc. Linn. Soc. N.S.Wales, 1902, p. 16) suggests, that C. atropurpureus Gld. and 

 C. samoensis Hombr. & Jacq., should be the same as C. dcnticulatus Gray. As he says however 

 "appear to be synonyms", I have left Gocld's name to the species in question. It seems to 

 be rather variable in colour.

Stat. 277. Kulewatti-bay, Dammer-island. 45 M. Sand. 2 Spec. 



The specimens vary much in colour and coarseness of sculpture. The great depth on 

 which the specimen from Stat. 98 has been dredged, may be due to its being an empty shell, 

 which will have sunken to the bottom. 



2. Monodonta (s. str.J canalifera Lamarck. 



Lamarck. An. s. vert. Ed. Desh. Vol. 9, p. 177. 



KlENER. Coq. Viv. Vol. X, Trochus, p. 225, PI. 73, fig. 2, 3.

Stat. 277. Kulewatti-bay, Dammer-island. 45 M. Sand. 1 Spec. 



The specimen from Stat. 64 is the largest, being considerably larger than the measurements 

 given by Fisciier and Pilsbry (Alt. 24, diam. 20 Mill.) and surpassing even those of Lamarck's 

 shell (diam. 11 lignes), the Siboga-specimen measuring: Alt. 31, diam. 29 1 /,, Mill. lts sculpture 

 and painting is also coarser than in the specimens from the other Stations.
