nent eyes. The dorsal surface of the head also bears scattered tubercles 

 which are denser on the ventral surface. The eyes normally bear 13 or 

 14 round photophores on the ventral surface of the bulbus and around 

 the iris, somewhat in the arrangement found in Liocranchia reinhardti. 



The funnel is large and well developed and reaches to the level of 

 the midpoint of the eyes. The funnel organ is indistinguishable in 

 the present specimens, but according to Sasaki (1929) the dorsal 

 member is inverted V-shaped, with one large central lamella and one 

 on the middle section of each branch. The ventral pads are figured as 

 short, half-moon members. 



The arms are short, in the order 3.4=2.1, I very short. All the 

 arms possess dorsal and ventral protective membranes. The suckers 

 are globular, in two rows, with small smooth apertures. 



The tentacles are short, rounded in cross-section, stout at the base, 

 and tapering distally to the small, slightly expanded club. The 

 tentacle stalk bears small smooth-ringed suckers, somewhat widely 

 spaced and alternating on the distal half of the stalk. The club has 

 two protective membranes, one on each side, originating at the carpus 

 and extending to the tip. On the outer surface of the club a strong 

 swimming membrane originates at the middle of the club and extends 

 to the tip, expanded on the dorsal side. The tentacular suckers, 

 arranged in four rows, are small in the carpal region, large in the mid- 

 part of the hand, abruptly changing to small suckers in the distal 

 portion of the club, and terminating in a distinct group of four large 

 suckers on a circular pad. The hand suckers are round, those of the 

 median rows are about equal in size to those of the marginal rows and 

 bear about 20 sharp separated teeth on the cu"cumference of the 

 horny ring. 



The buccal membrane has seven supports and seven lappets. 



Measurements and indices of a female of Cranchia scabra Leach 

 from off southern Luzon are: 



Type. — British Museum (Natural History). 



Type locality. — Off the Congo, Africa. 



Discussion. — Despite the many hauls made by the Albatross, this 

 is the only specimen obtained by the expedition. This species is 

 among the commonest of all cranchiid squids. 



Distribution. — Cosmopolitan in all warm and temperate seas, 

 apparently living mainly in the upper layers of the sea.
