Pacific and inhabitants of mostly the coral-reef region, 

 such as Cyprcea arabica, annulus. Isabella^ errones and 

 oryzciy Conus magus, arenatus, achatinus, Sfc. Oliva cruen- 

 tatci, tremuUna and ericinus, those of the last named genus 

 often living in sand. Sulla cylindrica occurred in sandy 

 pools on the reef at Claremont Isles. Of Volutes, V. 

 Turneri lives on coral blocks at Port Essington, and V. 

 undulata partially buried in sand banks at Port Dahymple. 

 Conus maculosus is an inhabitant of the last-named loca- 

 lity. The Mitras found in the Littoral zone were all on 

 the north-east coast, and well known Indo-Pacific forms. 

 A new Murex was taken on mud at Port Curtis. Fascio- 

 laria coronata, Fusus alveolatus, and Triton verrucosus yvere 

 found on the reefs at Port Dalrymple. Many species of 

 Nassa, all known forms, were collected, mostly on mud in 

 tlie Littoral zone, chiefly in the north-eastern province. 

 Phos cyanostoma lives on muddy sand in the Trinity Bay 

 islets, where also in similar situations is Terebra maculata 

 and Pyramidella maculosa. Pyramidella auriscati is a 

 littoral shell among the reefs of the Claremont Isles. 

 Several Purpurce were taken on reefs and rocks at low 

 water ; among them was P. textiliosa, a Port Dahymple 

 species. .A Quay a lives on rocks about high-Avater mark 

 in Lizard Island. Several TerebrcB, including T. crenulata 

 dimidiata and affinis, inhabit muddy sand among Pipon's 

 Islets. The well-known Strombus luhuanus lives on sand 

 among the reefs at Eagle Island. A Cerithium inhabits 

 mud-flats at Port Molle and Pipon's Islets. Of the holos- 

 tomatous gasteropods inhabiting the Littoral zone, the 

 Nat'iccs, mostly well-known species, were taken in sandy 

 localities on the north-east coast, and the Neritce in the 

 same province, mostly on rocks or reefs. LiUorina pyra- 

 midalis and mauritiana are inhabitants of the rockv head-
