f. 4?—S. Ducatis, Chenu, Il. C. Spon. t. 8, f. 2. Purplish brown 
with elongated and rather distant white lamine; the lineation only 
commencing at the margin. 3. Philippines. The lineated style of 
painting, rather than the sculpture, appears to be the permanent

obsolete.

Small, scarlet, not variegated, armed with radiating costelle and 
several intervening minutely imbricated raised strie ; the half dozen 
principal riblets notched by imbricated rudimentary scales, which 
near the margin become strap-shaped and truncated. 13. China. 
Lamarck’s species, for which Knorr, yi. t. 12, f. 3, was doubtfully 
cited, is ill-defined. '

squamiferous raised radiating strie. 2. W. Indies.

that hue, and the ground white with chocolate-coloured spots near 
the beaks: rayed with numerous narrow little elevated ribs (none 
peculiarly prominent), that are armed with elongated moderately 
distant spines: interstices smooth, slightly concave, not sculptured. 
4. Sechelle Islands. The 8. AtBus of Chenu (Con. Il. Sp. t. 28, 
f. 5) may possibly prove a colourless variety. Z

8. Nicoparicus, Sow. (as of Ch. 7, f 469, 70) Th. 1, p. 428, t. 88, 
f.48. Small, white, with radiating rows of blackish chocolate-coloured 
spots; surface bristling with most numerous radiating rows of very 
delicate crowded spathulate spines (or elongated concave scales), which 
are not seated upon ribs, but upon slightly elevated strie. Var. 
Spots scarlet with dark centres: strize further apart and armed with 
most slender lamellar spines: interstices delicately shagreened. 14. 
Philippines. Not improbably the young of the next species.

27, 60. . Usually white, with chocolate-coloured spots near the 
beaks, and the lamime of a lilac colour: rayed with extremely 
numerous ribs, which are depressed, of nearly equal breadth (those 
towards the centre being rather the larger), and most thickly set
