20 CYPR^A. 



little hesitation in attributing to this species. One or more 

 additional adult specimens are now believed to exist. 



A*. Group 4. Ovate and ■pyriform. 



58. adeora, Soland., (f. 7, 8). — C. testa ovata, ventricosa, 

 dorso aurantia, lineis albis subtilissiniis transversis striata ; 

 extrernitatibus niarginatis incrassatis, pallidis ; basi rotunda, 

 pallide fulva ; apertura subsinuosa, sulco coluniellari lato 

 acute dentato, plica terininali tortua antice triplicata, ; den- 

 tibus columellas circa 41 brevissimis, labii 41, interstitiis 

 aurantiis ; labio antice excavate 



Note. — This celebrated species is still rare, and specimens 

 in good condition are still sought for. The curious white 

 collar-like margin, at each extremity, adds to the beauty of 

 the shell, and increases the singularity of its character. 



59. Tigris, Linn., (f. 172-1 75).— C. testa ovata, crassa, ven- 

 tricosa, griseo vel fusco vel aurantio varie nebulata, maculis 

 magnis rotundis irregularibus fuscis aut nigrescentibus satu- 

 ratis dorso et ad latera picta ; extrernitatibus obtusis, labii 

 postica elevatiuscula ; spira subdepressa, linea dorsali sub- 

 laterali ; columella subrotunda ; dentibus circa 22 brevibus, 

 rotundis, obtusis, 5 ad 6 anticis majoribus, terminali crasso 

 distanti, sulco columellari subplanulato ; labii dentibus circa 

 26. 



60. pantherina, Sol., (f. 69-71). — C. testa pyriformi, tenui- 

 uscula, ventricosa, griseo vel fusco vel aurantio varie nebu- 

 lata, maculis numerosis rotundis fuscis aut nigrescentibus 

 saturatis dorso et ad latera picta ; extrernitatibus productis, 

 anticis attenuatis ; dentibus columellas ch'ca 26, terminali 

 elongato subtortuo, labii 30 ; labio subattenuato ; spira sub- 

 umbilicata. 



Note. — Tigris and pantherina. Perfectly distinguishable 

 by the graceful form, more numerous teeth, produced ex- 

 tremities, and smaller spots of the latter. Both species are 

 subject to the deep mahogany variation, as well as the 

 overlaid yellow found in so many Sandwich Island shells. 

 The large and very ventricose varieties of G. tiyris are 

 much thinner than the smaller ones, which would seem to 

 indicate their having attained large dimensions before com- 

 pleting their growth ; the former have exhausted their se- 

 cretions, so as to have little calcifying power left for the 

 thickening process.
