 Cuming.) 



Conus tulipa. Con. testd oblongd, ventricosd, inflatd, 

 Icevi, columella basim versus leviter sulcata ; Cccruleo- 

 albd, rubido- ant purpureo-fusco longitudinaliter un- 

 datd, lineisque fuscis albipunctatis cingulatd; spird 

 brevi, obsolete coronatd, leviter canaliculatd, spira- 

 Uter striata; apice roseo, elato.acuto ; aperturd pa- 

 tente, fuuce purpureo-violaced. 



The tulip Cone. Shell oblong, ventricose, inflated, 

 smooth, columella finely grooved towards the base ; 

 bluish-white, longitudinally waved with reddish or 

 purplish-brown, and encircled with lines of white- 

 spotted brown ; spire short, obsoletely coronated, 

 slightly canaliculated and spirally striated ; apex 

 rose-tinted, elevated and sharp ; aperture open, in- 

 terior purplish-violet.

Hab. Island of Annaa, Pacific Ocean (found on the reefs) ; 

 Cuming. 



The above locality is particularized for this shell on 

 the authority of Mr. Cuming ; it is well known to in- 

 habit many other localities in the tropical regions. 



Species 129. (Mus. Cuming.) 



Conus intehmedius. Con. testd elongato-turbinatd, sub- 

 cylindraced, Icevi, columella basim versus subtiliter 

 sulcata; puniceo -rosed, maculis grandibus fuscescen- 

 tibus reticulatis interrupts bibalteatd, inter stitiis plus 

 minusve pallide reticulatis; spird convexo-elatd, spira- 

 liter striata; aperturd patente, fuuce pallide violaced. 



The intermediate Cone. Shell elongately turbinated, 

 somewhat cylindrical, smooth, columella finely 

 grooved towards the base ; scarlet rose-colour, 

 belted with two interrupted rows of large reticu- 

 lated brownish blotches, the interstices being more 

 or less faintly reticulated with the same colour ; 

 spire convexly raised, spirally striated ; aperture 

 open, interior pale violet.

I have long suspected this shell to be distinct from the 

 Conus geographus ; it differs constantly in form, in colour, 

 and in the general distribution of the brown reticulated 

 painting. These differences are unimportant however 

 compared with a character which it has in common with 

 the Conus tulipa, namely that of having the lower portion 

 delicately grooved. The base of the Conus geographus 

 does not present the slightest indication of this grooving, 

 nor indeed any inequality of surface beyond the ordinary 

 striae of growth, which pass in the contrary direction. I 

 notice this character in the Conus intermedius merely to 

 show that it cannot be a variety of the Conus geographus ; 

 the grooving must not be regarded as a specific pecu- 

 liarity, because, as already observed, it is common to the 

 Conus tulipa, as well as to another closely allied species, 

 the Conus obscurus (vide PI. XVI. Sp. 82.). 



Species 130. (Mus. Cuming.) 



Conus geographus. Con. testd oblongo-turbinaid, ven- 

 tricosd, tenui, inflatd, cceruleo et incarnato pallide 

 tinctd, rubido-fusco maculatd et reticulata; spird 

 concavd, leviter canaliculatd, spiraliter striatd, coro- 

 natd, tuberculis subcompressis, prominentibus ; apice 

 rosacea. 



The geographer Cone. Shell oblong-turbinated, ven- 

 tricose, thin, inflated, faintly stained with flesh- 

 colour and washy blue, blotched and reticulated with 

 reddish-brown; spire concave, slightly canaliculated, 

 spirally striated and coronated, the tubercles being 

 a little compressed and rather prominent; apex 

 rose-tinted.

Hab. Mauritius, Ceylon, &c. (found on the reefs). 



This well-known shell differs from its allied species 

 the Coni tulipa, intermedius, and obscurus in size, paint- 

 ing, and in the absence of fine grooves round the base. 



Species 131. (Mus. Cuming.) 



Conus lineatus. Con. testd oblongo-turbinatd, basim 

 versus granuloso-liratd ; albd, aurantio-fusco filisqut 

 traasversis numerosis tinctd, macularum albarum ir- 

 regularium fasciis tribus rc/inijuentibus ; spird d< -
