86 THE NAUTILUS. 



the slides investigated, but it was again a hurried journey. The 

 next year with the assistance of L. E. Daniels the work was 

 thorough. 



Oct. 17th, a month and a half from Tucson, the collector, 

 snails, snakes and ferns were on the train homeward bound, 

 and Cole wending his way over the toll road Tucson-ward. 

 Theodore, that splendid thirty- dollar horse, and also one of 

 Cole's, ate too much of a dry, short, delicate, mischievous 

 grass, and died at the end of the trip. 



A NEW OPISTEOSIPHON FEOM CUBA. 



BY WILLIAM F. CLAPP. 



Opisthosipfion berryi sp. nov. Plate VII, fig. 14. 



Shell longitudinally, finely plicate, ochraceous buff, encircled 

 with a broad chocolate-brown band on the periphery of the last 

 whorl and on the lower half of the earlier whorls; slightly shin- 

 ing; decollated; suture deep, crenate; four or five spiral ridges 

 appearing in the umbilical region; whorls (remaining) four, very 

 convex; aperture vertical, circularly oval, peristome white, 

 double; the inner, a brief continuation of the whorl; the outer, 

 on the right side, smooth, slightly expanded, at the suture 

 broadly expanded and excavated over the breathing tube, ad- 

 nate to the penultimate whorl; columellar margin expanded 

 horizontally above in a broad flange adnate to the penultimate 

 whorl, a large lobe curving over and nearly covering the umbil- 

 ical region, interrupted below by a broad sinus where the lip is 

 abruptly reflexed and attached to the whorl, a smaller lobe ex- 

 panded horizontally below. A minute breathing hole within 

 the aperture near the posterior angle, connects with a tube, 

 somewhat concealed in the expanded and excavated lip, which 

 curving back to the suture, descends and ends in the narrow 

 space between the ultimate and penultimate whorls. Numerous 

 strong raised lamellae mostly originating on the inner lip but 

 occasionally extending along the parietal lip, cover that portion 

 of the tube visible within the lip. Operculum as in Opistho- 

 siphon pupoides.
