82 THE NAUTILUS. 



Arnouldia Bgt., Bull. Soc. Mai. France, VII, 1890, p. 328. 



It is doubtful whether any Japanese species really belong to 

 Euconulus. Most of them have all the shell characters of Kaliella, 

 a genus abundantly developed in India, China and indeed the whole 

 Orient. Reinhardt's Japanese " Trochoconulus " I refer to Kaliella. 

 His " Discocomdus," judging from sinapidium, the only species I 

 have seen, might belong to Yitrea. Arnouldia nahaensis of Gude is 

 a Kaliella. 



Punctum japonicum n. sp. 



Shell minute, openly and rather widely umbilicate, depressed, thin, 

 light brown. Spire convex, low ; whorls 3tt, quite convex, separated 

 by deeply impressed sutures, regularly and rather slowly increasing; 

 last whorl tubular, rounded at the periphery. Sculpture of delicate 

 spaced, irregular lamellar riblets, the intervals sharply finely striated, 

 and with close spiral stria?. Width of the umbilicus is contained 

 about 3^ times in the diameter of the shell, all the whorls readily 

 visible within it. Aperture rounded-lunate, oblique, the peristome 

 simple and acute. 



Alt. 0.7, diam. 1.25, width of umbilicus 0.37 mm.

The only other known Japanese species of Punctum is " Helix 

 (Patula) lepta" of Westerlund, described from Nagasaki. It has a 

 much narrower umbilicus than P. japonicum, the last whorl is sub- 

 angular above, and it is described as with dense riblets. 



NEW RECORDS OF NEW MEXICAN SNAILS. 



BY II. A. TILSBRY. 



August 25th last, Professor T. D. A. Cockerell collected a few 

 snails " in Chicorico Canon, near Raton, New Mexico. This is in 

 the region of Quercus gambeli and Eobinia neomexicana, at an eleva- 

 tion of about 7000 ft. There are no previous records of mollusca 

 from this region. It is quite in the northern part of the State, only 

 a few miles from the Colorado boundary." The species are : 



Vallonia gracilicosta Reinh. 



Vitrina pfeifferi Newc. 



Euconidus fulvus ( M ii 1 1 . ) .
