58 CALYPTRiEDiE. 



15. CANCELLATA, f. 21, 22, Adams and Reeve. — Tumida 

 vel ventricosa, costellis radiantibus et liris interstitialibus can- 

 cellata ; apice retrorso vel subcentrali. — Our figure 22 is 

 of the form described in the voyage of the Samarang; f. 21 

 is a capuliform specimen in hand. The radiating ribs with 

 minute interstitial cross-bars are the same in both. 



16. ALVEOLATA, f. 23, AclatTis. — Irregularis, sub-elevata, cos- 

 tellis radiantibus acute nodosis et rugis concentricis decussata. 

 Irregular, rather raised, decussated with radiating sharply 

 notched riblets and concentric wrinkles. 



17. VANiKOROENSis, f. 17, Quoy. — Conica, obliqua, obtusa, 

 striis radiantibus, inaequalibus sculpta. — The writer does not 

 understand this species, nor does he suppose that Mr. Reeve 

 has identified it. In the Astrolabe one side figure is given, 

 which we copy, and the other figures are of distorted shells. 



18. Lataedi, f. 18, Reeve. — Hipponiciformis, radiatim 

 costata ; costis rotundis, longitudinaliter valde striatis. — The 

 sculpture of this obliquely conical species is that of fine 

 small fibres gathered up into bunches so as to form ribs. 



19. PiLEOPSis, f, 40, 41, Quoy. — Parva capuliformis 

 tenuissima, liris majoribus radiantibus et interstitialibus 

 minutis sculpta. — Small, cap-shaped, very finely sculptured, 

 with larger radiating and smaller interstitial raised strise. 

 Probably the same as figured by Reeve for C. vanikoroensid, 

 Quoy. 



20. HiPPONiciFOEMis, f. 24, 25, 26, Reeve. — Eotunda, 

 parva, oblique elevatim producta, striis minutis, subcequalibus 

 sculpta ; apice obtuso valde retrorso. — Eound, small, 

 obliquely elevated, produced, with very fine, nearly equal 

 strise. 



21. UMBO, f. 49, 50, Reeve. — Elevato-conica, rotunda, 

 distanter radiatim subnodoso-costata, interstitiis minute 

 striatis ; apice retrorso, submarginali. — Conically raised, 

 round, distantly rayed with nodose ribs ; interstices minutely 

 striated, apex bent back towards the margin. 



22. scuTULUM, f. 46, 47, Reeve. — Orbicularis convexa, 

 radiatim lirata ; liris distantibus, interstitiis minute striatis, 

 margine striato, appendice minuta, apice valde retrorso. — 

 Small and round, with equidistant radiating ribs and inter- 

 stitial strise ; apex near the margin ; margin striated.
