STENHELTA LONGIROSTRIS, Norman & T. Scott, (Pis. XL fig. 4; 

 XII. fig. 3 ; XIV. fig. 3 ; XV. figs. 3, 13 ; XVI. fig. 2.) 



1905. Stenhelia longirostris, Norman & Scott, Ann. & Mag. Nat. 

 Hist. ser. 7, vol. xv. p. 288. 



It resembles Stenhelia veflexa, T. Scott, in its general appear- 

 ance and in the structure of its appendages, but is distinctly 

 smaller. 



The specimen represented by the drawing (PI. XII. fig. 3) 

 measures about '88 mm. (about 5 V of an inch). The body 

 is subcylindrical and the forehead is produced into an elon- 

 gated and rather slender rostrum. 



The antennules of the female are composed of eight joints; 

 the first joint is slightly longer than the second and nearly 

 twice as long as the third joint ; the fourth joint, which 

 is rather longer than the third, has the upper distal angle 

 produced forward to the end of the next joint and bears 

 a long sensory filament : the fifth, sixth, and seventh joints 

 are small and about equal in length, while the ultimate one 

 is nearly twice as long as that which immediately precedes it 

 (PI. XV. fig. 3). The annexed formula shows approximately 

 the proportional lengths of the various joints :

The secondary branches of the antennas are three-jointed 

 and of moderate length. 



The second maxillipeds are furnished with t\vo moderately 

 long setae on the distal extremity of the first joint ; the second 

 joint is narrow and subcylindrical, with a longitudinal row 

 of spinules on its inner aspect, a small seta springs from 

 near the middle and another from near the end of the inner 

 margin ; the slender spiniform terminal claw springs from 

 the end of a narrow and moderately long basal part, as 

 shown in the figure (PI. XV. fig. 13). The other cephalic 

 appendages are nearly as in S. reflen-a. 



The first four pairs of thoracic feet are all moderately 

 slender, and both branches are three-jointed. In the first 

 pair the first joint of the inner branch is about as long as 

 the entire length of the outer branch, the second joint is 

 small, being only about half the length of the third joint, 

 while the second and third are together about equal to two- 

 thirds the length of the first joint. The joints of the outer 

 branches are subequ;il in length (PL XVI. fig. 2). The 

 next three pairs are each similar to the same pair in Stenhelia 

 reflexa (PL XIV. fig. 3). Each of the fifth pair has the
