HYPERIDEA. 933 



Figure 7, Plate 67, represents a young individual probably of the 

 preceding species. The head is larger in proportion, and but one 

 pair of antennae could be distinguished; these were short, and had a 

 styliform termination, which was shorter than cephalothorax, straight 

 and acute. Length, one-eighth of an inch. Colours, as in the pre- 

 ceding. Taken the following day, October 31, 1838. 



Lestrigonus fuscus. 



Thorax 7-articulatus, segmento primo fere celato. Abdominis segmentum 

 ultimum suturd discretion, penultimo dimidio angustius. Antennae 

 l?nce corporis longitudine, 2dce valde longiores ; basi ad apicem infe- 

 riorem acuto. Coxa pedum 6 posticorum apice obtusa et unguis 

 dimidio tarsi brevior. Pedes 5ti Qtis Imisve paulo longiores. 



Thorax seven-jointed, first segment nearly concealed. Seventh seg- 

 ment of abdomen separated by a suture from preceding, half nar- 

 rower than the sixth. Superior antennae as long as the body, infe- 

 rior one-fourth longer, inferior apex of basal portion acute. Coxa 

 of six posterior feet obtuse at apex, and claw less than half the 

 tarsus in length. Feet of fifth pair longer than sixth or seventh. 



Plate 67, fig. 8 a, animal, enlarged; b, base of superior antennae; c, 

 extremity of abdomen, excepting first pair of stylets. 



Atlantic ; latitude 1° south, longitude 17° to 18° west. Collected 

 at 4 A. m., November 3d and 5th, 1838. 



Length, two lines. Colour, dark reddish brown, pervading whole 

 animal, verging in some parts towards pale reddish ; but colour pro- 

 bably not constant. Greatest height of head about twice its length, 

 rounded in front, but profile slightly flattened about the antennary 

 area. Segments of thorax all very narrow, first hardly apparent. 

 Base of inferior antennae having the last joint longest. Claw of six 

 posterior legs not half as long as preceding joint ; coxa about as long 

 as width of thorax ; fifth joint rather longer than either of the pre- 

 ceding. Ciliae of natatories about twice as long as the lamellae. 

 Lamellae of stylets about one-third their whole length, subcultriform,
