44 THE NAUTILUS. 



mens of Nautilus pompilius thrown up in Edeu Bay. It is difficult 

 to conceive how they get there ; it is an enormous expanse to be 

 drifted away from any of the Pacific Isles. Can it be possible that 

 they are eaten by whales and that the shells is extruded as excre- 

 ment ? I make this suggestion because great schools of whales 

 come in there, it is said, to rub themselves on the coarse gravel 

 bottom of the bay. Dr. J. C. Cox, in letter to Editor. 



PARTULA : NOTES AND CORRECTIONS. Partula eximia Hartm. 

 P. macgillivrayi. 



P. Brazieri Pse. is a good species. 



The type example of Partula neweeaitiarum was lost with the ves- 

 sel on its return to Mr. Garritt at Tahiti. W. D. Hartman. 



A NEW SPECIES OF HEMPHILLIA. In examining the slugs 

 referred to Hemphillia glandulosa in the collection of the Academy 

 of Natural Sciences, we found that two species have hitherto borne 

 this name. The true H. (jlandulosa is a small slug, with distinctly 

 papillose mantle ; the pedal line hardly rises at the tail, and the 

 caudal gland is surmounted by a conspicuous horn. The other 

 form, which we call H. camelus, is much larger, the mantle is not 

 papillose, and the pedal groove rises abruptly and conspicuously 

 at the tail, and there is no noticeable horn there. Types from 

 Old Mission, Idaho, collected by Hemphill. The species are easily 

 separated by external characters, but the internal anatomy shows 

 even more important differences, which will be described and figured 

 in the second installment of our " Revision of American Slugs," now 

 in preparation. H. A. Pilsbry & E. G. Vanatta. 



RECENT PUBLICATIONS RECEIVED. 



An apparently very thorough monograph of the Cephalopoda of 

 the Gulf of Naples, by Guiseppe Jatta, has appeared in the " Fauna 

 and Flora des Golfes von Neapel " (23d monograph). The illus- 

 trations are incomparably magnificent. 



Mr. Felix Bernard 1 has detected a stage of shell-growth in bi- 

 valves earlier than the prodissoconch, which be proposes to call pro- 

 tostmcum. He finds the protostracum on the summit of the prodis- 

 soconch. The Glochidium stage in Uuionidre is its equivalent.
