The following shells were dredged off Port Jackson Heads at 

 a depth of 45 fathoms, and were handed to me for description 

 by Mr John Brazier, C.M.Z.S. 



TEREBRA LAURETANiE, N. S. 



T. parva, pyramidata, turrita, opaca, liaud nitente, albida, 

 maculis latis, quadratis, fulvis tesselata (in ult. anfr. maculis 2 

 lin. distinct, zonatd); anf. (nucl. excluso) 8, planatis, Uneis incre- 

 menti undulatis rugoso-striatis, superne valtde spiraliter canalicu- 

 latis supra canalem obsolete granulans ; nucleo (\\ anfr?) natici- 

 formis nitente, basi maculata, convexa, striata labro acuto, colu- 

 mella nitente, exacte definita, canali recurvo, brevi, sutura acute 

 impressa. Long. 20, lat. 6J mil. 



This Terebra resembles a good many of our Australian and 

 Tasmanian forms in the distinct groove in the upper 3rd part of 

 the whorls. It is most like T. Brazieri, Angas, but that shell is 

 always longer, and has acute shining ribs. Until we are better 

 acquainted with the younger forms of this and similar shells its 

 specific value must remain doubtful. 



TURRITELLA INCISA, N. S. 



T. parva, pyramidata, turrita, spira acuta, subpellucida, pallide 

 fulva ; anf. 13, utrimque late marginatis margine elevata, striata, 

 albo fulvoque eleganter tesselata, intra margines bi-liratis ; 5 anf 

 apicalibus translucidis et roiundatis; basi concava, lirata; apertura 

 quadrata, labro acuto, sinu angusto, profunde insignito. Long. 11, 

 lat. 3 mil. 



This remarkable little Turritella is distinguished by the narrow 

 and very deep sinus in the outer lip. It has a raised tesselated 

 margin above and below on each whorl, and the intervening 

 space has two distinct lirae. The colour is pellucid, golden red- 

 dish, aud the tesselations are red and white. We have one or
