pale yellow. Whorls five, separated by an impressed suture. 

 Sculpture most elaborate; numerous small spiral keels, amounting 

 to thirteen behind the aperture, encircle the shell, wider apart 

 and more prominent at the periphery and growing weaker and 

 closer as they retreat from it. Crossing the spirals, so as to form 

 rhomboidal meshes, are longitudinal ribs of the same calibre, 

 amounting on the last whorl to thirty-two. At the point of 

 intersection the latter rise into small vaulted prickles. This 

 sculpture gradually fades away on the earlier whorls, the longi- 

 tudinals outlasting the spirals. The first three whorls are smooth. 

 At the edge of the umbilicus the cancel! ate sculpture ceases 

 abruptly. The base is rounded, about one-fifth of its diameter 

 being occupied by an open, funnel-shaped umbilicus. Aperture 

 oblique, oval, angled above. Outside the incrassate lip is less 

 massive than in southern species of the genus, on the base it is 

 not thickened at all. A smooth callous ridge is spread on the 

 preceding whorl. Major diameter 5, minor 4, height 3 mm. 



Hob. — Off Cape York, Queensland; one specimen, dredged by 

 Mr. J. Brazier. 



Type to be presented to the Australian Museum. 



The novelty is related to L. calliglypta, Melvill, from the same 

 district, but is of less height, greater breadth and has more 

 developed spiral sculpture. The slight development of the 

 thickened lip agrees with the latter and with Cyclostrema cingu- 

 lifera, A. Ad.

It was pointed out last year by Prof. Tate* that under this 

 name Tryon had described and figured another species. As the 

 real Rissoa angeli has yet been left unfigured, I now give a 

 drawing of an example received from the late Mr. C. E. Beddome. 

 This specimen measured *8 mm. long; -54 mm. broad.
