yellow or darker, with a peripheral band of white more or less ob- 

 scurely and narrowly margined above and below with chestnut, and 

 with dark chestnut maeulations between the ribs. Columella bear- 

 ing four plaits which are continued as cords on the short anterior 

 canal : above these cords are one or two obscure, slightly nodulose 

 ones. 



The type, U.S.N.M. No. 517056, measures : Height, 10 mm., breadth, 

 4.7 mm. It was collected in 3-6 fathoms at Santa Rosa on the north 

 coast of Pinar del Rio, Cuba, during the Tomas Barrera Expedition. 

 Three paratypes were collected at the same place, and one specimen was 

 found at La Esperanza, Pinar Del Rio, Cuba. 



Genus FENIMOREA Bartsch, 1934 



FENIMOREA MOSERI BRUNNESCENS, new subspecies 



Plate 20. Figure •"> 



Similar in shape and nature of axial and spiral sculpture to typical 

 Fenimorea moseri (Dall) from the lower west coast of Florida, but 

 of a uniform light vinaceous-cinnamon color (Ridgway's Color 

 Standards), except for the two glassy white nuclear whorls. 



Type. U.S.N.M. No. 517055. measures: Height, 23 mm.; breadth, 

 8.4 mm. It was dredged in 14 fathoms off Fort Walton, Okaloosa 

 County, Fla., by Maxwell Smith. 



This is an interesting race from the coast of the "panhandle" of 

 Florida, a conchologically little-known region. 



Genus CRASSISPIRA Swainson, 1840 



CRASSISPIRA (CRASSISPIRELLA) MESOLEUCA, new species 



Pjlate 20, Figure 15 



Shell solid, elongate-ovate, with a narrowly conic spire. Nucleus 

 low, rounded, of almost 2 smooth whorls. Postnuclear whorls axially 

 ribbed, the ribs crossed by spiral cords, which on the later whorls 

 become slightly nodulose and whitish where they cross the axial ribs ; 

 fine threadlike striae are found in the spaces between the stronger 

 spiral cords and between the shoulder of the whorls, where the axial 

 ribs end, and the suture; in this space there is also a rather strong 

 subsutural keel. The color is usually of varying shades of chestnut, 

 becoming occasionally almost blackish and rarely yellow; the ends 

 of the ribs at the shoulder are decidedly whitish and the subsutural 

 area may be lighter in color. Aperture narrow, outer lip with a 

 dee]) sinus Between the subsutural keel and the shoulder. Anterior 

 channel rather broad and rather shallow; a trace of a stromboid 

 notch is evident, Basal fasciole weak, closely spirally corded.
