Murex laminatns, Tate & May, Proc. Linn. Soc. N.S. Wales, xxvi., 

 1901, pp. 352, 4.5.3, pi. xxiii., f. 3. 



Stations 13, 37, 49. 



Judging from an apparently adult example, 7-5 mm. in length 

 and 3-5 in breadth, this species seems to me more suitably placed 

 in Trojyhon than in Murex. 



A few examples occurred in 63-75 fathoms off Port Kembla; 

 off Botany Bay in 50-52 fathoms; and one in 41-50 fathoms off 

 Cape Three Points. 



TROPHON SIMPLEX, sp. nov. 



(Fig. 93.) 



Stations 13, 35, 37, 49, 55, 57. 



Shell small, I'egularly fusiform. Colour cinnamon-brown, paler 

 at the apex and canal. Besides the two-whorled protoconch there 

 are three adult whorls which are rather long and rounded. 

 Suture impressed. Sculpture : on the spire are 

 — first two then three— strong spirals which on 

 the last whorl increase to about eight. The 

 longitudinals commence on the antipenultimate 

 as close, bold ribbing, imitating varices ; in 

 some individuals the radial sculpture fades away 

 on the later whorls ; in other instances, as in 

 the shell figured, strong longitudinals cross the 

 spirals, producing nodules at the junction. 

 Behind the aperture a strong outstanding varix 

 occurs. Aperture oval, neither ridged nor 

 furrowed within, inner lip projecting a narrow 

 rim free from the body whorl. Canal long, 

 straight and open. Length, 8 mm. ; breadth, 

 3*8 mm. 



One or two examples each from 63-75 fathoms 

 off Port Kembla (type); 41-50 fathoms off Cape Three Points; 

 50-52 fathoms off Botany Bay; 54-59 fathoms off Wata Mooli; 

 11-15 fathoms of Crookhaven Eiver; and 22-38 fathoms oft' Port 

 Hacking. Also taken by Mr. G. H. Halligan and myself in 100 

 fathoms sixteen miles east of Wollongong.
