differs in having a larger eye, a smaller number of modified scales in 

 lateral line, and in having the vent placed more posteriorly. Distance 

 from end of mouth to tip of snout nearly \ of head; length of snout a 

 little greater than length of mandible ; width of interorbital space about 

 i snout and length of eye ; maxilla extending slightly beyond anterior 

 margin of eye ; the mandible a little behind end of eye. A few scales in 

 several series behind the eye. Mouth rather large. Teeth on the pre- 

 maxillaries and mandible in somewhat broader bands than those on the 

 maxilla; vomerine patches broad, well separated in front. Tip of tongue 

 free. Integumentary flap not extending much beyond margin of sub- 

 opercle. Branchiostegals 10 ; gill rakers 2 above, 12 below, the longest 

 scarcely half as long as eye. Distance of dorsal from tip of snout 2 in 

 head, length of base f height of body ; longest ray 2| in head and nearly 

 equal to height of body ; about 34 rows of scales in front of dorsal. Ven- 

 tral entirely in advance of dorsal, its distance from end of head (2 inches) 

 equal to distance from tip of mandible to end of head. Length of 

 ventral (f inch) about equal to that of dorsal base, or twice length of 

 eye; origin of ventral about under twenty-eighth row of scales ; distance 

 of vent from origin of the ventral greater than length of head, close 

 to anal origin ; distance from the dorsal origin to that of the anal (26 

 inches) 3 times length of dorsal base. Nine or ten enlarged scales in lat- 

 eral line in front of the ventral origin and about the same number between 

 ventral and vent. Dorsal scaly less than \ its height ; about 12 rows 

 of scales between the dorsal origin and lateral line, and only about 2 

 rows below lateral line. 



Scales silvery, the light orange-brown body color showing through 

 them ; branchiostegal membrane bluish ; inner surface of gill covers 

 nearly black; inside of mouth bluish. Three specimens known, one 

 obtained by the Blake, at Station LXX, off Guadeloupe, 769 fathoms ; 

 one at Station 2380, by the Albatross, from which the present description 

 is drawn, and another at Station 2381 by the same vessel. Station 2380 

 is in N. latitude 28 02 / 30", W. longitude 87 43' 45", from 1,430 fathoms. 

 Station 2381 is in N. latitude 28 05' 00", W. longitude 87 56' 15", 1,330 

 fathoms. This species may be identical with Aldrovandia johnsoniana, 

 Vaillant, from off the Canaries and the coast of Africa, but the types of 

 the latter species were badly mutilated. (Goode& Bean.) (gracilis, slender.)

 the Gulf Stream. (Co-type, No. 44327. Coll. Albatross.) 



911. ALDROVANDIA PALLID A, Goode & Beau. 



Head 7f ; depth 15. Head naked, with the exception of a patch of 

 scales beginning behind eye, its greatest width nearly equal to i width 

 of body. Eye midway between tip of snout and head, its long diameter 

 equal to i length of snout, also equal to interorbital width. Nostrils 

 close to front of eye, the anterior in a short tube, which ends in a little 

 pointed flap ; the posterior larger, nearly elliptical in shape ; distance 

 from front margin of mouth to tip of snout nearly i length of snout. 

 Maxillary extending to below front of eye. Teeth in broad, villiform
