above under ¢), one with a few, the other without bands, but agreeing otherwise with 
King’s description and Reeve’s figure. A specimen in Paetel’s collection (measurements d) 
is still smaller, otherwise similar. Philippi? drew his fig. 3 from one of Cuming’s 
specimens, this figure being very near c in size, but remarkably narrower, diam. only 
184 millim. ; his fig. 2 has a very low spire, with flat suture, and it probably represents 
the young condition of another species. The measurements under 0 are taken from a 
specimen from Panama, given to me by H. Dohrn, this agreeing very nearly with 
Reeve’s figure. 
In the collection of the late Dunker there are also some eggs of this species, these 
measuring 4 millim. in their largest diameter. 
19. Ampullaria conoidea, sp.n. (Tab. XXIV. figg. 10, 11.) 
Testa elate conoidea, vix rimata, solida, verticaliter plicato-striata et lineis subtilissimis spiralibus sculpta, 
pallide fulva, fasciis nonnullis angustis fuscescentibus picta; anfr. 6, convexi, sutura sat profunda, 
ultimus globosus; apertura pro ratione generis parva, 3,7, longitudinis occupans, oblongo-elliptica, 
peristomate leviter expanso, albo, margine externo valde arcuato, margine columellari crasso, appresso, 
rimam umbilicalem pene prorsus claudente, superne in callum distinctum parietis aperturalis abeunte, 
fauce albida, fasciis pellucentibus.

Hab. Costa Rica (Van Patten, in Mus. Berol.). 
This is a very remarkable species; it agrees with A. oblonga, Swains., and some 
allied forms in having the umbilicus nearly or quite closed by the thickened columellar 
margin, but differs from them in the high spire and the globose (not oblong) form of 
the last whorl. In one of our specimens, the larger one (a), the outer margin of the 
aperture is not expanded and unicolorous white; in the other (0) it is distinctly 
expanded and marked with the continuation of the bands. ‘These are the only 
examples known to me.

Differs chiefly from the allied forms (A. cumingi and A. conoidea) in the shorter 
spire; the bands are very pale, scarcely visible; the apex, which is somewhat worn 
in the only specimens seen of A. conoidea, is here well preserved, shining, smooth,
