Pacific and iuliabitauts of mostly the coral-reef region, 

 such as CyprcBci arahica, annulus. isabella, errones and 

 oryza^ Coiius magus, arenatus, achatinus, Sfc. Oliva crueji- 

 tata, 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 Dakymple. 

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

 lity. The 3Iitras found in the Littoral zone were all on 

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

 A new 3Iurex was taken on mud at Port Curtis. Fascio- 

 laria coronata, Fusus alveolatus, mid Triton verrucosus were 

 found on the reefs at Port Dalrymple. IMauy species of 

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

 the 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 Terehra 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 Dalrymple 

 species. A Quoya lives on rocks about high-water mark 

 in Lizard Island. Several TerehrcB, including T. crenulata 

 dimidiata and a^nis, inhabit muddy sand among Pipon's 

 Islets. The well-known Stromhus luhuanus lives on sand 

 among the reefs at Eagle Island. A Cerit/iium inhabits 

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

 tomatous gasteropods inhabiting the Littoral zone, the 

 Naticce, mostly well-known species, were taken in sandy 

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

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

 midalis and mauritiana are inhabitants of the rock}^ head- 

 lands of Broken Bay ; other forms were collected at Port
