26. balteatus, Sowb. — C. breviusculus, subtrigonus, fulvus, 

 minute striatus; ad basin et interne violaceus (f. 71). — Resem- 

 bling C. citrinus or C. lividus, but finely striated. 



27. tabidus, Reeve. — C. subpyriformis, tenuis, minute sulca- 

 tus, ad basin sulcis fortioribus, distantibus; colore pallido (f. 108). 

 — A pale, rather pyriform shell, finely striated above and distantly 

 sulcated below. 



28. crepusculum, Beeve. — C. fulvus, ad basin cseruleo tinc- 

 tus, superne kevis, infra minute granulatus ; spira acuminata, an- 

 gulo minutissime nodulifero (f. 96). — Like C. lividus in the blue 

 tip, but a lighter and more angular shell. 



29. granifer, Reeve. — C. subfusiformis, granosus, pallidus ; 

 spira subcanaliculata, apice fusco (f. 109, 110). — Our second 

 figure is too darkly coloured. The shell is granulated in every 

 part, and towards the base in ridges. 



30. archithalassus, Dillw. — 0. solidus, vix ventricosus, 

 albus, flavido minutissime reticulatus, castaneo fasciatus, fasciis 

 et interstitiis maculis cordiformibus albis inspersis ; variat granu- 

 latus (f. 24, 25). — This is the "crowned admiral" of collectors, 

 and although slightly more ventricose and shouldered, I have 

 great hesitation in admitting its separation from C. ammiralis. 



31. princeps, Linn. — C. solidus, turbinatus, irregulariter coro- 

 natus, aurantius, lineis undulatis longitudinalibus tenuibus vel 

 magnis ornatus (f. 31, 32, 33). — The shorter variety (f. 33) 

 with minute lines is C. lineolalus of Valenciennes. 



32. rutilus, Menke. — C. tenuis, turbinatus, laevis, roseus. mi- 

 nute corouatus (f. 323). — I should have expected the young of 

 C. princeps to present the appearance of this smooth, pink, turbi- 

 nated, lightly coronated and thin shell, but am assured by Mr. 

 Cuming that those collected by him are quite different. 



33. Kupellii, Reeve. — C. solidus, versus basin granulatiin 

 striatus; spira obtusa, nodulis coronalibus obtusis ; ad spiram et in 

 medio albus, fusco maculatus, omnino lineis fuscis cinctus (f. 1-13). 

 — White at the top, and in a middle band speckled with brown ; 

 the other parts chestnut, encircled with dark lines, which from the 

 middle to the base are raised and granulated. 



34. Taheitensis, Bnir/. — C. subpyriformis, fusco-purpurascens, 

 maculis albis vel creruleis fluctuatis ad spiram et in medio ornatus, 

 omnino leviter striatus; spira obtuse coronata (f. 26). — This 

 purplish-brown shell is slightly striated, and is more pyriform
