II. Retiferi. 



C. retifer Menke (= solidus Sowb.). — Amply characterised by 

 its pyriform outline, spiral striation, great solidity, and coarse wide- 

 spread reticulation. Hab. Philippines and other eastern islands. 



III. Textilia. 

 (a) Vera. 



C. textile L. and eight varieties. — The type may be characterised 

 thus : — Shell white, banded twice or thrice spirally with interrupted 

 yellow-brown or chestnut blotches, longitudinally lineated with zigzag 

 or undulating blackish-brown pencillings, nearly enclosing triangular 

 or crescent-shaped white spaces of larger and smaller dimensions. 



The forms and limitations of this very widely-spread and common 

 eastern species are difficult to define; certain, still undescribed, are evi- 

 dent when a series of what is still called typical C. textile is examined, 

 but many of these undoubtedly run into each other. However, the 

 following seem fairly distinct and recognizable when once learnt, with 

 the exception perhaps of the aptly-named C. concatenatus Kiener : — 



1. tigrinus Sowb. — To a great extent destitute of the brown bands, 

 the pattern, therefore, seeming less involved. 



2. vicarius Lam. — Form more pyramidal, pattern coarser and larger 



in detail, with greater preponderance of the white triangular 

 patches. 



3. verricuhim Reeve. — Shorter and thicker than the other varieties, 



markings as in vicarius, but with a greater amount of yellow 

 blotching. 



4. concatenatus Kien. — Hardly distinguishable from vicarius, in my 



examples, exhibiting a much more open reticulated net-work, with 

 the orange blotches smaller in proportion. It can scarcely be 

 doubted, however, that intermediate forms occur, and I do not 

 consider it a very satisfactory variety. 



5. script us Sowb. — A beautiful species, closely reticulated with pale- 



brown lines. The finest example I have seen of this was shown 

 me some years ago by Mr. F. P. Marrat, and was about 63 mm. 

 in length ; it is undoubtedly nearly akin to the next form. 



6. canonicus Hwass. — Differing in its mostly darker reticulations, 

 with but little orange blotching, the form being conically pyra- 

 midal, rather solid ; in some examples a pale-pink suffusion 

 overspreads the whole surface. My largest specimen is 78 mm. 

 long. 



7. condensus Sowb. — Pink tinge always constant ; a dwarf form, 



with pale markings, as in scriptus. 



8. dalli Stearns. — Of lighter build; spire convex, mouth roseate. 



From California. I have never seen this species.
