Length of head 13 » 21 > 



Diameter of eye 3 > 5 > 



Interorbital width 8 > 12 » 



Length of snout 5 * 7 ' 



Transverse diameter of ventral disk 7 ' '° ' 



Distance from snout to origin of anal 22.5 > 37 ' 



This fish is rather similar to Liparis steineni FiSCHER with regard to some re- 

 lative dimensions, but differs widely from the same in having simple, not tricuspid, 

 teeth and the vent situated close to the ventral disk. Concerning the situation of 

 the vent in Liparis steineni FISCHER says in the diagnose ' (1. c): "Der After liegt 

 dem Anfange der Analflosse etwas näher, als dem Hinterrande der Bauchscheibe." 

 To make sure that there was no mistake about this, I wrote to Dr. L. Reh in Ham- 

 burg and asked him kindly to reexamine the type-specimen of Liparis steineni. 

 Having done so Dr. Reh informs me that the vent of this specimen lies ''mindestens 

 I cm. hinter dem Hinterende der Saugscheibe, aber nur etwa '/^ cm- von dem Vorder- 

 ende der Analflosse". This important difference is therefore quite clear, and about 

 the shape of the teeth cannot be any uncertainty as FiSCHER declares them to be 

 "dreispitzig" in Liparis steineni. This latter form is consequently just as clearly a 

 Liparis as the present species is a Careproctns, although the dimensions of both are 

 somewhat similar. As a Careproctus, however, the present species is less modified 

 than other species of the same genus, and its disk is especially better developed. 

 The fact that the diameter of the ventral disk is only contained twice in the length 

 of the head, or twice as long as the diameter of the eye, approaches Careproctus 

 georgianiis to the members of the genus Liparis and separates it easily from all 

 species of its own genus. It appears also to be the first known representative of 

 Careproctus, not only in the antarctic waters, but on the southern hemisphere,^ and 

 forms thus a very important discovery. From South Georgia no other member of 

 Discoboli has been recorded before, e.xcept the above mentioned specimens o{ Lipa- 

 ris steineni FiSCHER, which were collected at the shore of Royal Bay. C. georgia- 

 ti7is is of course an inhabitant of deep water but perhaps less so than some mem- 

 bers of the genus, which may account for its less modified structure.

' The most southern Careproctus hitherto described was C. longifilis Gar.man (Mem. Mus. Comp. 

 Zool. Vol. XXIV Cambridge Mass. 1899) which was caught in a depth of 1.S23 fathoms lat. 2° 35' N.; 

 long. 83° 53' W. C. longifilis is, however, very different from the present species as it is a much more 

 modified and a more pronounced deep-sea fish.
