ludiiig C. fraguin, C. svhrugosum, and C. unedo ; Saii- 

 guinolaria rvgosa at Dunk Island ; species of Mesodesma 

 in sand, and Mactrca and TeUince in mud ; a new Psam- 

 mohia at Port Essington as also a new Pholas that bores 

 into coral. Other species, members of the same genera, 

 are cast on shore dead. 



Eegion of Weeds equivalent to the Laminarian 

 Region of the Eiu'opean Seas. Some seventeen or eighteen 

 locaHties in this Bathymetrical province were explored by- 

 means of the dredge, varying in depth from one to seven- 

 teen fathoms. In the south-east Australian province the 

 principal Gasteropoda procured were Bulla brevis, at Port 

 Jackson, in 6 fathoms ; Cyprea oryza, at Port PhiUip, in 5 

 fathoms ; Calyptrcea connata, in 6 fathoms, Port Jackson, 

 with Nassa suturalis, and another, a new Terebra, Mono- 

 tigma casta, Mitra sordida, a Marginella, a Columbella, and 

 Struthiolaria oblita. A Phasianella was dredged in from 

 3 to 5 fathoms on sandy mud, at Port Phillip, with Elenchus 

 rutilus, Marginella fornicata, and Cerlthiuin granarium. 

 In the North-east Australian province, a different set of 

 shells was dredged in similar depths, such as a Sigaretus, 

 possibly new, Fissurella calyculata, Mitra obeliscus, a Tur- 

 ritella, a Murex, Columbella versicolor, and a new species 

 off Cape York, Ranella pulckella, new, several Nasscs, 

 Phos senticosa and Blainvlllei, and sculptilis, in 3 and 

 5 fathoms, off Cape York ; Strombus Campbelli, in mud off 

 Cape Upstart; Cerithiiim obeliscus, and a new species of the 

 genus Obeliscus. In the deeper localities CyprcBu fimbriata 

 occurred, dead, off Cape Capricorn ; and two species of 

 Ranella, one being R. pusilla, in 17 fathoms, off the Percy 

 Isles. The univalves dredged among the Louisiade Islands 

 in this region of depth were mostly known forms, such as 

 Conus betulhms, Oliva sanguinolenta, Mitra exasperata, 

 Terebra maculata, consors and labiata ; these were all 

 taken in less than six fathoms water.
