 VARUNA ALTIMANA, new species. 



Type-locality. — Point Jamelo, Luzon; river, in 20-foot seine; 

 July 13, 1908; 1 male. 



Type.— Cat. No. 44558, U.S.N.M. 



Dimen^ons. — Male type, length 20.7 mm., width 21.8 mm. 



Surface uneven; H-depression deep; a groove either side of the 

 intestinal region; a transverse groove runs inward behind the second 

 and behind the third tooth; frontal and hepatic regions depressed; 

 surface finely punctate and covered with still finer reticulating lines 

 formed by flattened, confluent granules. Front broad, prominent, 

 feebly bilobed, its lateral margms making an obtuse angle with the 

 anterior margin. Upper border of orbit strongly S-shaped, forming 

 at its union with the front a closed fissure ending in a triangular 

 sinus. Antero-lateral margms moderately convergent, 3 teeth acute, 

 with straight sides and separated by deep, narrow sinuses. Postero- 

 lateral marguis subparallel, shghtly smuous; a granulated fine, 

 begiiming a little ways from the margin and considerably behind 

 the last lateral tooth, forms the upper boundary of the very short 

 and broad obUquely-vertical section of the branchial region. 



Antennules obliquely folded; nasal lobe triangular. Sides of 

 ischiognath parallel; in the male the exognath is large and much 

 swollen; reaching nearly to the end of the merognath and one and 

 three-fifths times as wide as the ischiognath; in the female the 

 exognath is much flatter and narrower, being not quite so mde as the 

 ischiognath. 



Chehpeds stout in male; a fringe of hair on upper and inner edges 

 of merus; carpus with a long spine which is triangular at the base, 

 the tip acuminate, a tubercle at base of spine, just below anterior 

 margin of segment; palms high, postero-inferiorly much swoUen, 

 posteriorly rugose; upper margin compressed and elevated in a flat 

 lobe occupying the proximal two-thirds; fiiigers very broad and flat, 

 narrowly gaping; immovable finger horizontal, with a blunt longi- 

 tudinal ridge continued almost imperceptibly on the palm, and a
