TRAVISIA PROFUNDI. . 387 



but little higher than the neighboring ordinary papillae occurring elsewhere on 

 the somites. These setigerous papillae decrease in size caudad, finally becoming 

 wholly obliterated, and leaving the setae sessile, arising directly from slits in 

 the body-surface. There are lateral sensory pits between the neuropodia and 

 notopodia on most somites, as in Travisia. (Plate 67, fig. 5). 



The pygidium is very small, short, and cylindrical, longitudinally weakly 

 furrowed or canaliculate, and thus divided into twelve or fourteen inconspicuous 

 lobes. Paler than the rest of the body. (Plate 68, fig. 2).

Travisia profundi, sp. nov. 

 Plate 67, fig. 1-4. 



The color of the preserved animal is grey throughout. 



The body is pointed at both ends, subfusiform, though conspicuously 

 broadest in front of the middle, being broadest and decidedly deepest at 

 about one third the distance from the anterior end. The dorsal surface strongly 

 convex, the ventral more weakly so, but not truly flattened and not at all fur- 

 rowed. The type is 27 mm. long and, at the thickest region, 5.25 mm. wide and 

 6 mm. deep. (Plate 67, fig. 1). 



The prostomium is a very small and bluntly rounded organ which is wholly 

 smooth. (Plate 67, fig. 1, 2). 



The second somite widens strongly caudad like the frustum of a cone. It 

 is distinctly biannular and is crossed longitudinally on each side at the dorso- 

 lateral level by the nuchal groove, which terminates anteriorly at the prostomium. 

 The annuli are covered densely with contiguous, nodular, pustule-like papillae, 

 of which there are five or six transverse rows on the first and four or five on the 

 second. The first of these two annuli on the ventral side is deeply notched 

 caudally, bordering the mouth in front and anteriorly at the sides, while the 

 mouth completely divides the second annulus ventrally, its ends thus forming 

 the remaining part of the lateral borders of the mouth. (Plate 67, fig. 2).
