 commenting on Lamarck's name. 



The species has not appeared before in Australian waters. 

 We dredged a few examples in 5-10 fathoms. 



GlYPHOSTOMA TRIBULATIONIS, n.sp. 



(Plate xlii., fig.81.) 



Shell small, solid, biconical, angled at the periphery. Colour 

 white or bufi". Whorls six, including a small smooth two-whorled 

 protoconch. Sculpture : about a dozen undulatory radial .ribs, 

 equal in breadth to their rounded interstices, arise at the suture,. 

 are most prominent on the shoulder, and fade on the base. 

 Ascending the spire, these radials gradually diminish. About 

 twelve small spiral threads, which traverse ribs and furrows 

 alike, are evenly distributed between the shoulder and the 

 anterior extremity. Finally, a secondary sculpture of fine close 

 grains, arranged radially and spirally, is spread over the whole 

 surface, giving a *' gritty" aspect to the shell. Aperture narrow^ 

 protected by a strong projecting varix, the outer lip with two or 

 three ill-defined tubercles within, canal short. Length 4-75, 

 breadth 2-5 mm. 



Abundant in 5-10 fathoms, at Hope Island. I found a small 

 form of it, in 15 fathoms, off the Palm Islands. The strong 

 shoulder-angle and sanded surface are the principal features. 

 Cape Tribulation is on the mainland, opposite the Hope Islands..

Hitherto this species has not been recorded as Australian. It 

 was originally described from the Loyalty Islands, and then 

 identified from Funafuti. The dark patches on the lips are use- 

 ful recognition-marks. As the original figure is vague, I have
