variety of B. succinoides (Petit). The only specimen I have seen 

 belongs to the National Collection at South Kensington.

Testa imperforata, ovato-conica, tenuis, nitens, carneo-albida vel 

 luteo-straminea, plerumque maculis parvis nigro-fuscis p7'o- 

 miscue conspersis picta, ad apicem carnea ; spira acute conica ; 

 anfractus 6, convecciusculi, longitudinaliter Icevissime irregu- 

 lariter striati ; sutura leviter impressa ; anfractus ultimus 

 subventricosus, ^ longitudinis fere cequans, bast rotundatus ; 

 apertura subovalis, leviter obliqua, latiuscula, intus albida, 

 maculis anfractus ultimi transmeantibus ; peristoma tenue, 

 rosea marginatum ; marginibus callo tenuissimo junctis. 

 Long. 25, diam. maj. 15 millim. 

 Hob. Bogota, 



A pretty little shell, varying considerably in form and colour, but 

 the lip appears to be always thin and prettily edged with red. Of 

 the two specimens lent me for description by Mr. Da Costa, one is 

 nearly white, profusely sprinkled with small brown spots, while 

 the other is of a yellovvisli straw-colour (more decided yellow 

 towards the apex), with only a few pale spots. I have as yet only 

 seen very few specimens, but these exhibit considerable variations in 

 their proportions. One apparently abnormally inflated specimen 

 measures nearly 15 millimetres in width and only about 20 in 

 ength ; while the narrowest specimen measures scarcely more than 

 1 1 millimetres in width to 2 1 in height. 



BuLiMULUs DA-COST^, H. sp. (Plate XXIII. figs. 15, 16.) 



Testa anguste sed profunde umbilicafa, elongata, nitida, irregu- 

 lariter striata, pallide fulvo-carnea, longitudinaliter fusco 

 undulatim strigata, maculis parvis nigro-fuscis hifasciatim 

 picta ; sjnra convexo-conica, apice acuto ; sutura leviter im- 

 pressa ; anfractus 6, convexiusculi, ultimus spiram suhcequans, 

 basi attenuatus ; columella obliqua, reflexa ; apertura subver- 

 ticalis, intus rosea, maculis perlucenfibus ; peristoma simplew, 

 leviter reflexum. 

 Long. 26, diam. maj. 1 1 millim. 

 Hab. Bogota (Mus. Da Costa). 



I have as yet only seen a single specimen of this species, which 

 may be found to vary as much as the last. It seems, however, to be 

 distinct from any hitherto known. 



BULIMULUS ftLANDINIFORMIS, n. sp. (Plate XXIII. figs. 13, 14.) 



Testa anguste perforata, oblonga, tenuissima, nitida, pellucida, 

 stramineo-albida, longitudinaliter ruguloso- striata ; spira 

 turrita, apice obtuso ; anfractus 7, convexiusculi, sutura anguste 

 cunaliculata sejuncti ; anfractus ultimus i, longitudinis vix 

 cequans, basi leviter attenuatus ; apertura subovalis, fere ver- 

 ticalis ; columella rectiuscida, reflexa, perforationem fere 

 tegente ; peristoina simplecv, acutum.
