 xv., p. 82, fig. 1474, $. 1848. 



Flagellum. Basal enlargement very high, rotundate, the whole 

 upper margin elevated in the form of a very high and thin laminar 

 keel. Procurrent portion very long, longer than the lamina, the 

 anterior bend near the apex of the jaw and farther forward than the 

 first large tooth. Eecurrent portion very long and slender, gradually 

 tapering towards the apex, cylindrical and almost straight, reaching 

 back beyond the eyes and passing high above the basal enlargement ; 

 the apex not needle-pointed but somewhat blunted by a very minute 

 dilation of the upper edge (fig. 266). 



Upper jaw of mandibles in $ with three teeth near the apex, 

 followed by a long, slightly concave or nearly straight, toothless 

 interval ; the first tooth very small and weak, the second and third 

 straight and strong ; first tooth of the basal series small, the second 

 strong and straight and as large as the distal pair. Terminal fang 

 curved downwards at the tip, the upper surface flattened and dilated 

 inwards under the bend of flagellum, the dilated part ending ante- 

 riorly in a minute tooth but scarcely elevated along the inner edge, 

 the inner keel of the upper surface being practically obsolete ; the 

 procurrent portion of the flagellum occupies almost the entire width 

 of the fang in the region of the anterior bend. Upper side of the 

 fang on a level with that of the rest of the jaw and therefore not 

 at all depressed, its under side with a convexity at the base, which 

 bears the two large teeth. Lower jaw with a pair of large teeth and a 

 small tooth between them, just in front of the hind tooth ; the upper 

 surface not sulcate laterally, its outer edge rounded off in the toothed 

 region. 



? and young with only one small tooth between the second and 

 third large tooth in the upper jaw and between the two large teeth 

 in the lower jaw.
