miniaceum, Pall. ? and of a species of Volsellu evidently the same 

 as the smooth variety mentioned ahove, but partly white (long. 5-i m., 

 alt. 3|m.). 



I have not noticed any internal laminse, but there is a very feeble 

 median coluinellar lira. The colour verges towards a dull ochreous 

 in many specimens, and the grey tinge of the preceding is very 

 feeble. It differs not more in size from the latter than the indivi- 

 duals of this group do mutually. 



Var. Q. ebenea (Thylacodus). 



T. solitaria, substantia dura, ebenea, nitidida, spiraliter torta ; 

 anfr. contigui, liris parvis remotis, rugis incrementi obsoletis- 

 simis, remotis, punctis asperis irregularibns in intersectionibus ; 

 anfr. ultimus prcelongus glaber, zonis pallidis ; columella lira 

 mediana acuta. 

 Diam. aperturse 3 m.

 pi. iv. f. G (sed specim. paululum majora quam nostra). 



Hab. Ins. Phihppin. ; two agglomerated specimens, one of which 

 has a very long apertural tube. 



This shell is perhaps more allied to var. y ; but I put it here on 

 account of the solid substance of the shell and the dark colour ; the 

 first whorls approach strikingly to one of the specimens of the last 

 group. 



Var. I. picea (Thylacodus). 



T. solitaria, spiraliter torta,lateraliter affixa; anfr.graciles,j}arvi, 

 liris validis circiter 4-5, striis incrementi acutis, inde liris sub- 

 tiliter cremdatis ; anfr. ultimus porrectus repens (corrodensl) 

 pentagonus (?) substantia crassa. 

 Diam. aperturse vis 1 m. 

 Vermilia subcrenata, Chenu, 111. tab. ix. f. F (simillima). 



Hab. ? Four or five specimens on a young Ostrea cumingii, 



Dkr., which is found at the Philippines. 



I cannot decide whether it is partly overgrown by the oyster, or 

 corroding, which is less probable (Mus. Cuming). 



Var. K. indentata (Thylacodus). 



T. succinea, hucilluc badia ; anfr. graciles, contigui, irregulariter 

 spiraliter torti, liris validis 4-5, interstitiis plerumque Icevius- 

 culis ; liris transversis cequidistantibus {in locis oecultis forti- 

 oribus), i7ide quadratim reticulata ; apertura circularis. 



Diam. fere 2 m. 



Hab. Ins. Philippin. {Mus. Cuming), specimen solitarium. 



This form corresponds to forma 1 of V. variaiis, D'Orb. 



Var. X. moniltfera (Thylacodus). 



T. lateraliter affixa, irregulariter spiraliter torta, pallide auran- 

 tiaca; anfr. graciles, contigui, liris 3-1. pidcherrime moniliferis,
