82 THE DISCOBOLI. 



The Challenger specimen was also a female with ova, and measured 

 seven and a half inches in length ; it had D. 60, A. 50, P. 12 + 3. Dr. 

 Giinther says of it : " Fortunately those parts about which Collett's descrip- 

 tion leaves us in doubt are well enough preserved to confirm his supposi- 

 tion that this fish is the type of a distinct genus. The ventral disk, or 

 indeed any external trace of ventral fins, is absent, and the lower portion 

 of the pectoral fin is separated from the upper by a smooth space, without 

 any of those intermediate filaments which are shown in Collett's figure. 

 The three lower rays are connected by membrane to their tips, and form a 

 fin by themselves. The posterior part of the vertical fins is also less ele- 

 vated, the rays being directed more backwards. The vent occupies a 

 similarly advanced position as in Liparis." 



Collett's type was taken in the open sea west of Beeren Eiland, at a 

 depth of 658 fathoms. The habitat given by Giinther is " Knight Errant, 

 Station 8, 1882; depth 640 fathoms." 



There are several points in which the figures given by the authors cited 

 do not agree, but their significance can only be determined by comparison 

 of the types, or by more examples. On the Bear Island specimen as figured, 

 the caudal is subtruncate and covered by dorsal and anal for two thirds of its 

 length, the space between the two portions of the pectoral has filamentary 

 rays, the gill opening extends down a little in front of the base of the pec- 

 toral, and the distance from the mouth-cleft is greater to the orbit than to 

 the nostril. On the Challenger drawing, the fish has a long pointed tail less 

 than half of which is covered by dorsal and anal, the pectoral filaments are 

 entirely absent, the gill opening does not extend down in front of the pec- 

 toral, and the distance from the mouth-cleft to the orbit is much less than 

 to the nostril.
