Turbonilla (Pyrgiscus) cascoensis new species. 
PI. 12, figs. 29, 40. 
Shell elongate- conic, milk white (nuclear whorls decollated). Post- 
nuclear whorls evenly moderately rounded, with appressed summits; 
marked by moderately strong, low, broad, rounded axial ribs. Of 
these there are about 24 upon the fourth remaining turn; 28 upon the 
5th, 6th, and 7th ; 36 upon the 8th ; on the latter part of this whorl 
they become much enfeebled while on the penultimate they are very 
ill defined. In addition to the axial ribs the whorls are marked 
between the sutures by five strong spiral rows of pits and 13 faint 
lines of different strengths which pass across the intercostal spaces, 
up on the sides of the ribs, but do not cross them. The detail arrange- 
ment is as follows: between the first (peripheral) and the next line 
of pits, there is one line of moderate strength ; between the second and 
third, there are a fine, a strong, a moderately strong, and another fine 
line; between the third and fourth there are a strong and a very fine 
line ; between the fourth and fifth one strong line occurs ; while poste- 
rior to the fifth are three very fine fines then a space followed by two 
more fine lines. Of the lines of pits the fourth is the strongest, the 
fifth next, while the three others are of equal strength. Periphery 
and base of the last whorl well rounded, the latter crossed by the 
continuations of the axial ribs anfl about 14 fine wavy spiral striations,
