CONUS. 



Plate XXII. 



Species 122. (Fig. a and c, Mus. Cuming; Fig. b, Mus. 

 Wigan.) 



Conus monachus. Con. testa oblongo-turbinatd , subcy- 

 lindraced, laevigata, basi sulcata ; pallide cceruled, oli- 

 vaceo-casio nebulosd et undatd ; spird breviuscull- 

 conicd, spirattter striata, apice subobtuso. 



The monk Cone. Shell oblong-turbinated, somewhat 

 cylindrical, smooth, grooved at the base ; pale blue, 

 waved and clouded with olive-grey ; spire rather 

 shortly conical, spirally striated, apex somewhat 

 blunt.

Lamarck, Anim. sans vert., vol. vii, p. 478. 



Hab. Asiatic seas ; Lamarck. 



The Conus monuchus is very closly allied to the Conus 

 achatinus ; it may, however, be readily distinguished by 

 not having any of the interrupted transverse lines which 

 characterize that species. 



Species 123. (Fig. a, Mus. Cuming; Fig. b, Mus. 

 Stainforth.) 



Conus colubrinus. Con. testd oblongo-turbinatd, sub- 

 ventricosd, superne tumidiusculd, solic/d, inferne co- 

 arctatd, transversim subtilissime striata ; fused vel 

 aurantio- fused, maculis a/bis, elongato-cordatis, ir- 

 regularibus, sejunctis, profuse ornatd ; spird obtuso- 

 elatd. 



The snake-skin Cone. Shell oblong-turbinated, rather 

 ventricose ; upper part a little swollen, solid, lower 

 part contracted, very finely striated transversely ; 

 brown or orange-brown, profusely ornamented with 

 irregular, isolated, elongately heart-shaped white 

 spots ; spire obtusely raised.

Sowerby, Conch. Illus., f. 106. 



Hab. Island of Taheite (found on the reefs) ; Cuming. 



This is a very peculiarly spotted Cone ; the spots are 

 entirely separated from each other, and may be likened 

 in appearance to the globules into which oil separates on 

 the surface of water. 



There is a bad figure of the Conus colubrinus in Mar- 

 tini's Conch. Cab., vol. ii. pi. 54. f. 594. 



Species 124. (Mus. Stainforth.) 



Conus cervus. Con. testd majmculd, cylindraceo-ovatd, 

 subinflatd ; pallide rosaceo-fulvd, tceniis intequalibus 

 fulvo alboque promiscue articulatis cinctd; spird brevi, 

 spiraliler striatd, apice pallide rosaceo ; aperturce 

 fauce alba. 



The stag Cone. Shell rather large, cylindrically ovate, 

 a little inflated ; pale rosaceous yellow, encircled 

 with unequal fillets of promiscuously articulated 

 white and dull brownish-yellow ; spire short, spi- 

 rally striated, apex pale rose-colour ; interior of the 

 shell white. 



Lamarck, Anim. sans vert., vol. vii. p. 510. 



Conus bullatus, var., Sowerby, Conch. Illus., f. 24. 



Hab. ? 



It is related in my account of the Conus Deshayesii 

 (vide PL V. Species 2S.) how much I am indebted to 

 M. Delessert of Paris, and to his curator M. Chenu, for 

 an opportunity of examining the identical shell de- 

 scribed by Lamarck under the title of Conus cervus ; 

 and I now repeat my estimation of their courtesy, 

 because it has enabled me to correct the illustration of 

 a species hitherto unknown to English writers. The 

 Conus cervus, a magnificent specimen of which is now 

 before me, belonging to the Rev. Mr. Stainforth, is 

 nevertheless so closely allied to the Conus bullatus, that 

 I am strongly inclined to think with Mr. Sowerby that 

 it may prove to be a gigantic variety of that species. 

 It differs most remarkably in size, and it is of much 

 paler colour, but these differences cannot with propriety 

 be looked upon as specific distinctions. The difficulty 

 of uniting the Coni cervus and bullatus under one species, 

 with a proper degree of certainty, arises from our ha- 

 ving no intermediate examples. 



Species 125. (Mus. Cuming.) 

 Conus interruptus. Con. testd oblongo-turbinatd, sti- 

 pend' tumidiusculd, basim versus sulcata ; incarnatd 

 spadiceo longitudinaliter nebulosd, tu-niis frequent ibus 

 spadiceo alboque articulatis cinctd; spird concavo- 

 chihi, apice acuto ; apertura fauce purpun d. 

 Tin: interrupted Cone. Shell oblong-turbinated, 

 rather swollen at the upper part, grooved towards 

 the base ; pale rosaceous flesh-colour, clouded Ion-
