Plate III. 



Species 2. (Fig. 2 b, Mus. Cuming.) 

 Delphinula Formosa. Variety ft. Testa squamulis coc- 

 cineis, in seriebus parallelis dispositis ubique ornata. 

 Shell everywhere ornamented with small crimson-scarlet 

 scales, arranged in parallel rows. 

 This very pretty variety of the Delphinula formosa 

 (vide Plate I. Species 2.) is distinguished on account of 

 the rows of small crimson scales which cover its entire 

 surface. 



Species 3. (Fig. 3 b, Mus. Cuming.) 

 Delphinula aculeata. Variety /3. Testa superne levis. 

 Shell with the upper portion perfectly smooth. 

 It is important to observe, that the Delphinula aculeata 

 is sometimes destitute of prickles above the tuberculated 

 angle of the whorls. The most striking character of 

 thi°s species appears to be in the deep crimson or scarlet 

 painting which ornaments the back of the spines or 

 tubercles, and it is constant in all the specimens I have 

 seen. 



Species 10. (Fig. a and b, Mus. Cuming.) 

 Delphinula Peronii. Delph. testd plamlato-rotundatd, 

 spird subdepressd; peralbdjoraminibus irregularibus 

 profuse puncturatd ; anfraclibus angulato-convexis, 

 superne varicosis, varicibus obsolete bicarinatis ; aper- 

 turtefauce eximie margaritaced. 

 Peron's Delphinula. Shell flatly rounded, spire rather 

 depressed ; very white, -ofusely punctured with 

 irregular small holes, reir rkably so with a row of 

 large ones round the umbilicus ; whorls angularly 

 convex, surmounted with varices, which are obso- 

 letely double-keeled ; interior of the aperture deli- 

 cately lined with bright salmon-colour pearl.

 This is one of that curious group of Delphinula of 

 which four species are illustrated in the present plate. 

 The Delphinula Peronii is curiously punctured over, and 

 looks exactly like some baked preparation of white 

 sugar that I remember to have seen at coi.tectR.ners. 

 The whorls are strongly varicose, but only on the upper 



part, and this is a character I would notify as being pe- 

 culiar to the species. 



Species 11. (Fig. a and b, Mus. Cuming.) 



Delphinula Scalarioides. Delph. testd globulosd, 

 ulbd ; anfractibus rotundis, varicosis, varicibus ele- 

 vatis, solidis, annuliformibus ; interstitiis transversi 

 striatis, striis elevatis ; intus margaritaced. 



The Scalaria-like Delphinula. Shell globular, 

 white ; whorls round, varicose, varices elevated, 

 solid, ring- like ; interstices between the varices 

 marked across with raised striae ; interior pearly, 

 bright salmon-colour.

Hab. Island of Mindanao, Philippines ; Cuming. 



The whorls of this species, which is not punctured 

 like the former, are encircled with solid rings about 

 seven to the whorl, after the manner of a Scalaria ; the 

 shell might indeed be mistaken for one, were it not for 

 its solidity and pearly interior. 



Species 12. (Fig. a and b, Mus. Cuming.) 



Delphinula varicosa. Delph. testd angulato-globosd, 

 alba, foraminibus sparsim puncturatis ; anfractibus 

 superne angulatis, fortiter varicosis, varicibus multi- 

 carinatis et elevato-striatis ; intus margaritaced. 



The varicose Delphinula. Shell angulately globose, 

 white, punctured here and there with holes ; ribs 

 angular round the upper part, strongly varicose, 

 varices many-keeled and elevately striated ; interior 

 pearly.

Hab. Island of Corriegidor, Philippines ; Cuming. 



This species differs from the Delphinula Peronii in 

 having the spire more prominent, and varices entirely 

 across the whorls ; they are also more strongly and 

 closely set; the shell is moreover much more sparingly 

 punctured. 



Species 13. (Mus. Delessert.) 



Delphinula sph.krula. Delph. testd subdiscoided, vi 

 ridi coccineoque varie tinctd; spird depresso-pland ; 

 anfractibus superne angulatis, superficie nodoso-un-
