_Foliis ovatis, obtuse-acuminatis, caule volubili ramosissimo, ramulis diffusis, deflexis,_ a new species, discovered in Java by Dr. Horsfield, who has distinguished it by the above specific character. He informs me the natives give it the name of _Kakas-rambat_, which last word signifies twining or trailing. In the inflorescence and fruit it differs not from _G. racemosa_. * * * * * Pl. 17 [Illustration] BULIMUS zonatus. _Zoned Bulimus._ * * * * * GENERIC CHARACTER.--See Pl. 4. * * * * * SPECIFIC CHARACTER. _B. testa laevi conica; spirae anfractibus quinque; ultimo aliquantulum distorto; albis duabus fasciis ferrugineis inaequalibus; anfractu basali rufo duabus albis fasciis; apertura alba._ Shell smooth, conic, of five volutions, the last somewhat distorted; white, with two unequal ferrugineous bands; body whirl rufous, with two white bands. Aperture white. * * * * * A small though very elegant shell, seldom seen in Collections; nor do I find such a description of it as will identify the species. One figured by Martini, at _tab._ 134, _fig._ 1215, comes near it, but differs sufficiently for a specific distinction. Its precise locality is unknown: a fine specimen exists in my father's collection, who thinks it came from the East Indies; and this is the only one I have yet seen. The aperture is more round than ovate, and is less than one half the total length of the shell; the outer lip much reflected, and the transverse bands on the spiral whirls nearly obsolete. * * * * * Pl. 18 [Illustration] MITRA contracta. _Contracted Mitre_--upper figure. * * * * * GENERIC CHARACTER.--_Pl._ 23. * * * * * SPECIFIC CHARACTER. _M. (Div. 3.) testa sublaevi; margine superiore anfractuum prominente, anfractu basali in medio contracto_ Shell nearly smooth; upper margin of the volutions prominent; basal whorl contracted in the middle. * * * * * An undescribed species, for the loan of which I am indebted to Mr. G. Humphrey, of Leicester-street, whose knowledge as a collector, and integrity as a dealer, have gained him respect and confidence through a long life: and it is no less singular than true, that many genera of modern authors, now universally adopted, were formed by him near twenty-five years ago (under different names) in the _Museum Calonianum_, printed in 1797.
