54 THE NAUTILUS. 



of Trinidad, off the coast of Brazil, in approximately latitude 

 21 S., longitude 29 W. Comparing it with the description 

 published by Dr. von Ihering, I feel certain that it is the 

 species described by him. In fact, I am not altogether sure 

 but what this may be the same specimen described by Dr. 

 von Ihering. 



Unfortunately, the figure cited above is a mere outline 

 figure, and rather poor at that, so much so in fact that one 

 would not recognize the present shell were its status depend- 

 ent upon the figure alone, but the description is positive. The 

 rareness and isolated distribution of this species justifies redi- 

 agnosis and a good photographic figure, which are here pre- 

 sented. The shell will have to be known as Bulimulus (Proto- 

 glyptus) ~brunoi von Ihering (Plate IV, fig. 7). 



Shell very elongate-ovate, dingy white. The nepionic por- 

 tion consists of not quite one turn, which is well rounded, and 

 marked by slender, slightly protractively slanting axial rib- 

 lets. The succeeding turns are well rounded, appressed at the 

 summit, and separated by a. somewhat constricted suture. 

 They are marked by almost rib-like, decidedly retractively 

 curved incremental elements and slender spiral liratious, the 

 junctions of which form feeble tubercles. Base somewhat 

 prolonged, moderately rounded, very narrowly perforated, 

 marked by the continuation of the rib-like elements and spiral 

 lirations, both of which agree in strength with those on the 

 spire, but becoming more crowded on the anterior portion of 

 the base. Aperture oval; posterior angle acute (outer lip 

 fractured at the edge) ; inner lip slightly sinuous and nar- 

 rowly reflected ; parietal wall covered by a moderately thick 

 callus. 



The specimen, which may be the type, belongs to the Na- 

 tional Museum of Brazil. It has 7.3 whorls, and measures: 

 altitude, 19.5 mm. ; greater diameter, 8.3 mm.
