Ampullaeia. Castelloi, n.sp. Plate IV. Fig. 22. 



Testa sub-ovata, crassa, angustissime umbilicata, luteo-viridula ; 

 plus miQusve rufo-fusco fasciata, longitudinaliter irregulariter plicata ; 

 spira conica, elatiuscula ; anfractus 5, convexi, rotundati ; sutura 

 angusta ; anfractus ultimus obtusissime angulatus, supra angulum 

 Icvissime concavus, infra angulum convexiusculus ; apertura lata, 

 vix obliqua, fauce aurantiaca, vel rufo-puii)urea, plus niinusve 

 fasciata; columella crassiuscula, levitcr rcflexa, vivide ruf o-marginata ; 

 labrum acutum baud reflexum. Long. 65, maj. diam. 53 mm. 

 Apertura longa 45, lata 28 mm. Operculum tenue, nigrum, extus 

 leviter conca\iim, laminatum, intus nitens. Hah. — River Meta, 

 S.E. Bogota. 



A ratber solid sbell, witb a very narrow umbilicus, in some 

 specimens completely closed. The spire is conical, and tbe top of 

 the body whorl very slightly concave, the sides being somewhat flatly 

 convex. The columella is bordered with bright red. The above 

 dimensions are those of the largest specimen, most of them being 

 smaller, and presenting some variation in colour and form. (Named 

 after a relative of the discoverer.) 



Ampullaeia peetusa, n.sp. PI. IV. Fig. 23. 



Testa sub-ovata, solida, anguste umbilicata, luteo-viridula, longi- 

 tudinaliter irregulariter plicata, punctis numerosissimis minntissimis 

 pertusa; spira conica, elatiuscula; anfractus 5, convexi, rotundati; 

 sutura angusta ; anfractus ultimus sub-humerosus ; apertura latiiiscula, 

 vix obliqua, fauce rufo-pur[)ureo fasciata ; columella leviter reflexa ; 

 labrum acutum, baud reflexum, album. Long. 68, hit. 52 mm.

This species very closely resembles A. Castelloi, but differs from 

 it in the absence of the red colouring on the columella lip, and in the 

 presence of a fine sculpture consisting of rows of minute punctures. 

 The typo specimen (the only one I have seen) was wrongly labelled in 

 the Cumingian Collection A. Linnei, Phil.,' a species which it does 

 not at all resemble, and I have to thank Mr. E. A. Smith for this 

 opportunity of describing it.
