This species is no. 877 of Dr. von Ihering's register. It has 

 much the general appearance of Urosalpinx cinereus (Say), which 

 has about the same contour. The comjnon Antillean Sistrum nodu- 

 losum is more abbreviated, with far stronger tuberculation and a 

 short anterior canal. It extends southward to Rio Janeiro and Cabo 

 Frio, Brazil {Cf. Hidalgo, Mol. Viaje al Pacifico, p. G7, as R. tuber- 

 culoid Blv. var. ?). 



A NEW GUATEMALAN GLANDINA. 



BY HENRY A. PILSBRY. 



Glandina Iheringi n. sp. 



Shell obesely fusiform or biconic, the diameter half the altitude ; 

 pale brown, with occasional dark chestnut or purplish-brown variceal 

 stripes, inconspicuously bordered on the left side with whitish. 

 Surface shining, finely and evenly striated throughout, excepting the 

 smooth apical whorls ; spire conic, with nearly straight lateral out- 

 lines, the apex rather acute. Whorls 7^, a little convex, the earlier 

 2^ smooth, separated by a simple suture, the rest very distinctly mar- 

 gined below the suture by ait impressed line which defines a narrow 

 band of bead-like tubercles. Last whorl obese, its latter half not 

 rapidly descending, the last suture being consequently nearly parallel 

 ■with the others, in a dorsal view. Aperture somewhat over half the 

 shell's length, narrow ; older lip regidarly arcuate; columella subver- 

 tical, concave above, then sinuous and abruptly truncated and ex- 

 cised. Alt. 25, diam. 12^; longest axis of aperture 14^, greatest 

 width 5§ mm.
