46 THE NAUTILUS. 



Strikingly like Cl. Mweruensis, Smith (Proc. Zool. Soc. London, 

 1893, pi. lix, fig. 10), but smaller, differently colored and more regu- 

 larly lirate. The locality is very distant from lake Mweru, although 

 belonging to the same geographical region. 



For this and numerous other interesting shells collected during his 

 journeys in Central Africa I am indebted to the Fath. M. Guilleme. 

 The material collected by him will be reported upon in the near 

 future. As a species of Cleopatra was already named after him, I 

 am respectfully dedicating this new species to E. A. Smith, Esq., of 

 the British Museum. 



3. Pisidium planatum, Anc. 



Concha minuta, lenticularis, parum inflata, compressa, nitidula, 

 tenuis, pallide cinerea, striis concentricis exilibus crebre sub lente

 rotundata, postica fere duplo major, regulariter arcuata. Umbones 

 late depressi, obtusissimi, inermes, Icevigati. Dens cardinalis parvus, 

 laterales debiles. Ligamentum parvum, lineare. 



Diam. 3, alt. 2^, crass. 1^ mill. 



Hab. Andriba, Central Madagascar (teste Dautzenberg). 



A more depressed form than P. Madagascariense Smith, the 

 only other species of the genus described from the island. 



NOTES. 



ON THE HABITS OF PRATICOLELLA JEJUNA : In the vicinity of 

 St. Augustine, Florida, I found this species locally only west of the 

 city in the white sandy, scrub oak section, near the pines, under boards 

 and leaves, in fact this was the only shell found there. They were 

 undersize, and very thin, probably due to the unfavorable condition 

 for molluscan life. Mr. A. G. Reynolds writes me from Disston 

 City, Hillsboro county, Fla. : " It is found under dead leaves and 

 trash, occasionally under boards, and more rarely on pine stumps." 

 Mr. Charles T. Simpson in his valuable paper, " Contributions to the 

 Mollusca of Florida," (Proc. Davenport Acad. Nat. Sci., v, p. 66, 

 1886), says : " The only mollusk ever found in high, dry pine woods 

 in Florida. I have seen it crawling on barren dry sand near 

 Braidentown, and around my dwelling, and along the road in 

 Fogartville." C. W. JOHNSON.
