375. ruric.inosus, Lamk, — C. C. Colubrino similis, set! maculis 

 albis minoribus, numerosis, interstitiis articulato-lineatis (f. 590). 

 — Although the spots are smaller, and the interstices marked with 

 articulated lines, I doubt the propriety of separating this from the 

 preceding. 



376. citoCATUS, Lamk. — C. oblongus, transverse leviter striatus, 

 supra convexus, medio subcontractus, infra subattenuatus ; auran- 

 tius, albo sparsim maculatus (f. 588, 589). — In one variety the 

 white is more plentiful, but the species is not difficult to identify. 



377. pennaceus, Lamk. — C. solidus, subcylindricus, albus vel 

 roseus, rubro reticulatus, maculis aurantiis rubro alboque articula- 

 tis pictus, prope angulum convexus, infra liratus ; spira brevi, 

 obtusa (f. 599-601). — The first is the typical form of this vari- 

 able species. 



378. eptscopus, Lamk. — C. elongatus, cylindricus, maculis 

 magnis fluctuatis pictus ; interstitiis late reticularis ; spira brevi, 

 obtusissima (f. 596-598). — More lengthened and cylindrical than 

 C. pennaceus, with large, fluctuating, dark, reddish-brown patches, 

 which are not marked with articulated lines, and the interstices 

 reticulated with large meshes. 



379. omauta, Bntff. — C. elongatus, cylindricus, tenuiter stria- 

 tus, lineis rubesceutibus minute reticulatus, maculis magnis arti- 

 culato-lineatis latis fuscis bifasciatus ; spira brevi ; apice subacuto, 

 roseo (f. 594, 595). — The markings are finer than in C. pcnna- 

 ceus, the shape more lengthened and cylindrical. 



380. convolutus, Sowb. — C. quam C. omaria magis angusta- 

 tus ; spira elevata, acuminata ; roseus, minute et tenuiter roseus, 

 fauce pallide aurantius (f. 504). — This very distinct species has 

 an affinity with C. omaria, but it has an elevated sharp spire, and 

 is narrower, the whorls being as it were more closely rolled up. 

 I venture to draw from Mr. Cuming's specimen, and colour from 

 that of Mrs. Deburgh. 



381. aulicus, Linn.- — C. cylindricus, subventricosus, leviter 

 striatus, albus, areis maguis castaneis irregulariter angulatis pictus ; 

 interstitiis angulation linearis; spira pyramidali (f. 593). 



382. auratqs, Lamk. — C. C. cyliudrico similis, sed angustior, 

 aureo aut roseo tinctus; maculis plus minusve punctisa Ibis linea- 

 ris (f. 591). — Of a more narrowed cylindrical form than C. auli- 

 cus, with rows of small white specks on the brown marks. The 

 golden-tinted var. (not figured) is the most common.
