Shell rather soliil and tall, lanceolate. Colour uniform yellow. Whorls 

 seven remaining. Scul[)ture : — Large deep meshes are formed on the 

 body of the shell by the.iutersect.ion of the main sculpture; the ribs are 

 nine on the penultimate and eleven on the last whorl, elevated, perpen- 

 dicular, alternating from whorl to whorl, twice their breadth apart, 

 vanishing on the base and below the suture ; spirals sharj), elevated cords, 

 thirteen on the body whorl, three on the penultimate, over-riding the ribs ; 

 on the snout the ribs only survive as nodules; along the fasciole area the 

 spirals are entirely different, being three or four closely-packed threads. 

 Aperture wide; varix taller and broader than the ribs; seven small 

 denticules within the outer lip; sinus small and semicircular; canal short 

 and wide. Length 11 mm., breadth 4 mm.

The type from the " Chevert " collection, an immature shell, has been 

 compared with the s[)ecimen from Murray Island figured here. An earlier 

 misidentification of this Australian shell as P. tessellata was based on 

 material received from Pere Hervier so named. Both colour varieties, 

 that with black and that with orange spots (var. luteopicta Hervier), occur 

 in Queensland. A figure of a shell from the Red Sea is so like ours that 

 I venture to include C. dichronia as a probable synonym. If C maculosa 

 Pease should prove, as I suspect, to belong heie rather than to C. felina, 

 as Tryon indexed it, his name would take precedence.
