GURALEUS MOROLOGUS sp. nov. 
(Plate hi., fig. 146.) 
Daphnellu brazieri Hedley, Mem. Austr. Mus., iv., 1903, p. 392, fig. 107 
(not Clathurella brazieri Angas). 
Shell thin, slender-fusiform, sub-turreted, upper whorls with a sloping 
shoulder meeting a perpendicular periphery at an acute angle. The 
radials are prominent spaced ribs, nine to twelve on the last whorl, finally 
evanescent, acutely prominent on the shoulder, and diminishing in a 
backward curve to the suture. The spirals are of two grades; first spaced 
cords that over-ride the ribs and lattice their interstices; these vary in 
size and number, about twenty may occupy the last whorl; between these 
cords ave packed from three to ten minute threads; these small spirals 
cover the whole surface of the shell, and resolve under the lens into strings 
of small and close grains. Aperture :—Month narrow; columella straight ; 
lip simple, sharp, and produced; sinus broad and shallow. Length 8 mm., 
breadth 3 mm. 
At first acquaintance I mistook this for G. brazieri, which is more 
eylindrical, and has more and slichter radials. Superficially it resembles 
G. connectens, but microscopically the fine spirals of morologus ave seen to 
carry grains not apparent in connectens. The protoconch of morologus is 
also more bulbous than that of connectens. 
Hab. N.S. Wales:—50 to 52 fathoms, off Botany Heads (type) ; 
22 fathoms, off Manning River; 41 to 50 fathoms, Cape Three Points; 
63 to 75 fathoms, Port Kembla (‘ Thetis”? Expedition). Victoria :— 
Western Port (Gabriel).
