250 CONUS. 



A very neatly marked shell, allied to C. mahogani, ximines, 

 tornatus, &c., but perfectly distinct. The type, at present 

 unique, is now in Mr. Melvill's collection. It was found in 

 the collection of Sir Edward Belcher, labelled ' Panama,' but 

 as the labels of that collection were many of them misplaced, 

 the habitat is uncertain, 



450. GRACILIS, Sowerhy (f. 655). — C. testa elongata, fusca, 

 raaculis albidis irregulariter aspersa, sulcis angustis subdis- 

 tantibus crenulatis cincta ; spira elata, acuta, subgradata ; 

 apice papillari ; anfractus 9, leviter concavi, spiraliter bisul- 

 cati ultimns supra angulatus, basin versus multo attenuatus ; 

 apertura angusta. Long. 31, maj. diam. 10 mill. 



A narrow elongated species, peculiarly produced at the 

 base ; of a darkish brown colour, with an irregular sprinkling 

 of whitish patches. The unique specimen is now in the col- 

 lection of Mr. Melvill, by whom it was purchased from the 

 collection of the late Dr. Prevost. This is not (as supposed 

 by Mr. Tryon) a variety of G. aculeiformis, differing very 

 materially from that species in sculpture, and style of 

 painting. 



451. SUPERSCRIPTUS, Sowerhij (f. 656). — C. testa breviter 

 ollonga, solidiuscula, angulata, turgidula, Isevi, antice valide 

 sulcata, albida, caeruleo tincta, maculis grandibus fulvis irre- 

 gulariter ornata, fasciis numerosis angustis maculatis et quasi 

 literatis cincta ; spira abbreviata, fulvo strigata ; anfractus 

 concaviusculi, spiraliter sulcati ; apice acuto, roseo ; apertura 

 subangusta, fauce purpureo-fusco tincta. Long. 27, lat. 14 



mill. 



The specimen is in the collection of the Marchioness 

 Paulucci in Florence. Its bluish tinge of colour, and delicate 

 letter-like markings are remarkable. 



Hab. Madagascar. 



452. Paulucci^, Sowerhy (f. 658). — C. testa elongata, 

 solidula, obsolete striata, obtusissime angulata, antice atten- 

 uata albida, aurantiaco late interruptim fasciata, fasciis 

 castaneo-fusco longitudinaliter strigatis, aliter lineis auran- 

 tiacis eximie trigono reticulata ; spira pyramidali ; anfractus 

 planiusculi, leviter spiraliter sulcati ; apertura angusta, alba. 

 Long. 60, maj. lat. 20 mill. 



A beautiful species bebnging to the Gijlinder group, 

 somewhat resembling G. gloria-maris in form, and G. aureus
