Reeve's figures 20a and c in "Conch. Icon." are of the shells of the allied species 

 Gafrarium hi7nidtiin (Roding) and not of G. pectinatiim. Good figures of the species were, 

 however, published by Rômer and Pfeiffer, thèse authors also discussed at length the disting- 

 uishing characters of thèse two closely alHed species. 



The "Siboga" shells of G. pectinatum resemble more shells from the Torres Straits, and 

 differ from the Red Sea shells in having a slightly coarser sculpture. In large séries of shells 

 from varions localities the différences in the sculpture are bridged over, and it is difficult to 

 distinguish any varieties or local races. 



Distribution : — Gafrariitvi pectinatum is a wide-spread species in the Indo-Pacific Région, 

 and has also been recorded from the Red Sea and the Persian Gulf. 



In the "Siboga" collection it is represented by shells from the Anchorage off Kawio and 

 Kamboling Islands, Karkaralong Group (St. 129) and Sanana Bay, east coast of Sula Besi (St. 193).
