Pacific and inhabitants of mostly the coral-reef region, 

 such as Cypraea arahica, annulus. Isabella, errones and 

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

 tata, tremulina 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 Essiagton, and V. 

 undulata partially buried iu sand banks at Port Dalrymple. 

 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 weve 

 found on the reefs at Port Dalrymple. Many species of 

 Nassa, aU 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 Terebrce, including T. crenulata 

 dimidiata and affinis, inhabit muddy sand among Pipon's 

 Islets. The well-known Strombus luhuanns Hves on sand 

 among the reefs at Eagle Island. A Cerithium inhabits 

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

 tomatous gasteropods inhabiting the Littoral zone, the 

 NaticcB, 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. Littorina pyra- 

 midalis and mauritiana are inhabitants of the rocky head- 

 lands of Broken Bay ; other forms were collected at Port
