former opinion that it is preferable to keep them both in Kathetostoma. 

 Dr. Haast has proposed (Trans. N.Z. Inst., V., p. 274) to establish another 

 genus for the Cat-fish with a filament; hnt Kathetostoma was not separated 

 from Anema by Dr. Giinther on account of its having extra spines on the 

 prffioperculum, mandibula, and throat, as Dr. Haast supposes, but because it is 

 naked, while Anema jDossesses miniite scrdes. As, however, both our Cat- 

 fislies have minute scales, while one has a filament in its mouth and the other 

 has not, it seems to me impossible to keei> up this distinction. The adoption 

 of Dr. Haast's suggestion would necessitate the sepai'ation of our Cat-fish into 

 two genera, and add a third genus, where, I think, one is sufficient. I cannot, 

 therefore, agree with his views.

D. 18; A. 17; P. 17; V. 5. 

 Length three and a quarter times that of the head, which is nine times the 

 diameter of the eye ; interorbital space twice the diameter of the eye ; a 

 filament in the mouth below the tongue. 



Brown above, with large distinct pale spots on the back and sides ; pectoral 

 fins margined with white and dusky on the inside ; caudal whitish, with a 

 broad brown vertical band in the middle, and tipped with reddish. 

 General length 7 or 8 inches, sometimes reaching 11 inches. 

 The humeral and prseorbital spines are sharper and more developed than 

 in the next species, showing that it is not the young.

 D. 20 ; A. 18 ; P. 17 ; V. 5. 



Length three and three quarter times that of the head, which is twelve 

 times the diameter of the eye ; interorbital space two and three quarter times 

 the diameter of the eye ; no filament in the mouth. 



Brownish olivaceous above, with numerous small, often indistinct, pale 

 spots on the back, which are larger on the sides ; pectoral fins not margined 

 with white, and the inside mottled with olivaceous and brown ; caudal 

 reddish, marbled with olivaceous brown. 



General length about 16 inches, sometimes reaching 24 inches. 



The granulations on the cranial plates are of quite a diflerent chai'acter to 

 those of the last species, and ai-e much more obscure. The pores on the 

 inferior margin of the prseoperculum are proportionally much largei", and the
