or bands from the apex of the shell to the base, but are only distinctly 

 visible by means of a lens, and are more distinct on the two inferior 

 than on the two upper whorls. 



2. Melania fraseri, V. d. Busch. 



Testa tu)'rito-subidata, tenuis,.nitida, apice decollato ; anfracti- 

 bus 7\ subconvexis ; sutura mediocris j anfractus inferiores oli- 

 vacei et cum flammuUs fuliginosis ornati, superior es autem so- 

 lummodo fuliginosi, basis striata ; apertura ovata, effusa. 

 Long. 14'", diam. 3'" ; apertura longa 3'", lata 2'". 

 Hab. Ecuador. 



This Melania, which was also found by Mr. Fraser in Ecuador, 

 and which I dedicate to him, is distinguished by the coloration of 

 the shell ; the inferior whorls are of olive-yellow colour, upon which 

 appear dark-brown flames ; the upper whorls are, however, of a 

 uniform dark-brown colour. 



3. Ampullaria solida, V. d. Busch. 



Testa oblongo-conoidea, solida, Icevis, haud nitens, imperforata, 

 anfractibus 4 convexis, olivacea, fasciis fuscis obsoletis cir- 

 cmndata ; apertura ovato-oblonga, alba, intus cceridea ; labrum 

 crassum ; columella subcallosa, alba. 

 Altit. 18-19'", latit. 13'"; apertura 9'" longa, 6"' lata. 

 Hab. Ecuador. 



This Ampullaria, found also by Mr. Fraser in Ecuador, seems to be 

 in every respect like the A. spencei. Reeve, figured under 124 of his 

 ' Monograph of the Genus Ampullaria,' and is perhaps only a 

 variety of it. 



4. Ampullaria modesta, V. d. Busch. 



Testa globosa, solida, imperforata, haud nitida, apice eroso ; 



fusca sine fasciis, sed costulis Icevibus sparsim circumdata ; 



anfractibus 4 ; spira brevis ; apertura ovata, intus ccBsia ; 



labrum solidum, luteum. 

 Altit. 16'", latit. 10'" ; apertura 9'" longa, 6'" lata." 

 Hab. Ecuador. 



A mean-looking species, somewhat solid, distinguished by some 

 dispersed fore ribs upon the last whorl, visible with the naked eye. 



5. Ampullaria quitensis, V. d. Busch. 



Testa globoso-ventricosa, solida, profunde et anguste umbilicata, 

 spira exserta, anfractibus 5 convexis ad suturam impressis ; 

 virescens, obscure fasciata ; apertura ovata, intus cinereo 

 striata ; labrum vivide aurantio-rufum. 

 Altit. 17"', latit. 14'" ; apertura 9'" longa, 7'" lata. 

 Hab. Ecuador. 



Distinguished by the fire-red lip. On the interior of the aperture 

 are visible the indistinct bands of the exterior of the shell, as more 

 or less distinct grey bands.
