510 Mr. C. V. Burke on the Cyclogasteridse. 



(1898) indicates his uncertainty concerning the specific 

 individuality of C. reinhardi and C. micropus. However, he 

 lists a number of specimens as Liparis micropus, and figures 

 a specimen of what he considers to be Liparis reinhardi. 

 Collett (1905) lists a number of specimens as Liparis rein- 

 hardi^ and presents two figures (pi. ii. figs. 7, 8). The two 

 specimens represented by these figures doubtless belong to 

 different species. 



1 have examined but one of these three species, C. ranula, 

 but after studying the specific characters of the Pacific species 

 of the genus I feel convinced that both Liitken and Collett 

 are mistaken in their identifications. The two specimens 

 figured by Collett (1905, pi. ii. figs. 7, 8) certainly represent 

 two species. The specimen represented by fig. 8 apparently 

 belongs with the species described and figured as Careproctus 

 reinhardi by Collett in 1880 (pi. ii. figs. 15, 16). This 

 species appears to be the one described by Kroyer (1862, 

 p. 252) as Liparis reinhardi. The specimen figured as no. 7 

 appears to represent an undescribed species. It differs from 

 C. reinhardi in the much longer lower pectoral lobe and the 

 deeper body. The specimen figured by Liitken (18y8, pl.iii. 

 figs. 3, 3 aj as Liparis reinhardi belongs with this sj)ecies. 

 Liitken's specimen is here designated as tiie type of a new 

 species, Careproctus longipinnis. 



Careproctus longipinnis , Burke, sp. n. 



Type. 'Ingolf,' St. 139, north of the Faroe Islands; 

 depth 702 Danish fathoms. Figured by Liitken as Z. rein- 

 hardi in " Danish 'Ingolf ' Expedition," vol. ii. pt. i.. The 

 Ichthyological Uesults, pi. iii. figs. 3, 3 a. 



Distribution. Arctic Ocean ; Faroe Islands to Beeren 

 Island. 



Relationships. C. longipinnis differs from all the other 

 species of the genus from the same region in the deeper body 

 and the lower lobe of the pectoral being longer than tiie head. 

 The disk of C. longipinnis appears to differ from that of the 

 other species in being more deeply cupped, and the posterior 

 margin is folded over so that the disk becomes somewhat 

 triangular. The vent is next the disk. 



Description of type. The following notes are taken from 

 Liitken's description and figure : — 



Pectoral 31 ; caudal 10 ; head 4*9 in tlie total length ; eye 

 5 in the head ; disk l-G. (CoUett's specimen has dorsal 53 ; 

 anal 41 ; pectoral 30.) 



From the figure : — Body somewhat gelatinous ; depth of
