ENDEAVOUR SCIENTIFIC RESULTS. 



Gladius (sepiostare) elongate-oval in outline (Figs. 58-59), 

 broadest just back of the anterior third, thence narrowing 

 to a rounded-off angle in front, the posterior region less 

 rapidly tapering and more truncate ; dorsal surface marked 

 by numerous curved rows of coarse, granular, more or less 

 confluent tubercles, the rows corresponding in position to 

 the underlying lines of growth, and further ornamented by 

 three low, longitudinal ridges separated by shallow fossae of 

 about the same width, the median ridge rendered more 

 distinct than the others by traces of a faintly incised bounding 

 line ; ventral surface not greatly elevated ; striated area 

 with a broad central excavation boinided by diverging 

 lateral elevations, the lines of growth projected sharply 

 forward in the median line ; last loculus with an index of 16 ; 

 inner cone tapering rather sharply to a rounded point 

 behind, forming a somewhat broader, but still narrow, 

 callovised wall across the terminal part of the inner cavity ; 

 iSpine short, stout, blunt, the region separating it from the 

 shell margin, ventrally, thickened and very rugose. 



Radula (Fig. 61) with simple, sharply conic rhachidian and 

 first and second lateral teeth, very similar in general appear- 

 ance, thovigh differing slightly in detail ; marginals only a 

 little longer than the other teeth, slightly falcate in outline, 

 their points bluntly rounded.
