9. Physcosoma dentigerum Sel. and de Man. 
Shipley. P. Zool. Soc. London, 1898, p. 471. 
A few examples taken from borings in the coral rock. 
Locality. Minikoi, Laccadive Islands, also recorded from Funafuti, Rotuma and the 
Philippines. 
10. Physcosoma lucteum Sluit. 
Sluiter. Natuurk. Tijdschr. Nederl. Ind. xiv. 1885, p. 507. 
Two specimens which, though I failed to find the area of irregularly scattered hooks 
intercalated between 80 and 30 complete rows of hooks as described by Sluiter, in other 
respects seem to belong to this species, 
Locality. Hulule, Male Atoll, previously recorded from the Malay Peninsula. 
11. Physcosoma nigrescens Kef. 
Selenka. Die Sipunculiden, 1883. 
Three examples of this coral-boring form were taken at Inafuri, Goifurfehendu Atoll. 
It is a variable species, several local varieties having been recorded. 
Locality. Inafuri, Goifurfehendu Atoll, also recorded from the Fiji Islands, Funafuti, 
the Philippines, Mauritius, and the Red Sea. 
12. Physcosoma pacificum Ket. 
Shipley. P. Zool. Soc. London, 1898, p. 470 and Willey’s Zoological Results, Part 11. 
1899, p. 156. 
One example from Minikoi was found under the same conditions as S. vastus, and 
several others were obtained under growing coral masses in the lagoon ~ sand, principally 
under branching Porites and Madrepora, also found boring into coral rocks. 
Locality. Minikoi, Laceadive Islands, from Hulule, Male Atoll and from Naifaro, Fadifolu 
Atoll, and trom Goidu, Goifurfehendu and from Maradu, Addu Atoll, in the Maldives. 
This species extends from the Red Sea through the Indian Ocean to the Pacific. 
Mr Gardiner had already taken it at Rotuma and Funafuti. Dr Willey found it at Uvea, 
Loyalty Islands and in Blanche Bay, New Britain. 
13. Physcosoma pelma Sel. and de Man. 
Selenka. Die Sipunculiden, 1883. 
One specimen, small and difficult to recognize. It was of a dense black colour which 
must have been due to the action of the preservative reagent, as it is described in 
Mr Gardiner’s notes as transparent when alive. It was found amongst the castings of a 
large species of Ptychodera on the lagoon flat. 
Locality. Minikoi, Laccadive Islands. 
The species is also recorded from the Philippines, Java and Mauritius.
