This new generic name is to replace Grimaldia Chapman (Ann. Mag. Nat. Hist. (11), ix., April, 1942, pp. 272, 299 and 300), which is preoccupied by Grimaldia Chevreux (Bull. Soc. Zool. France, xiv., 1889, p. 283), a genus of Crustacea Amphipoda. Chapman's definition of Grimaldia constitutes the diagnosis of the new genus, Monacoa. Family Tachysuridae.

Genus Cochlefelis Whitley, 1941. COCHLEFELIS COLCLOUGHI (Ogilby, 1910) . Hemipimelodus colcloughi Ogilby, Proc. Roy. Soc. Qld., xxiii., November 7, 1910, p. 7. Croker Island, Northern Territory. Holotype (No. I., 1538) in Queensland Museum. Id. McCulloch, Austr. Mus. Mem., v., 1929, p. 61. Hemipimelodus colcloughi is evidently a second species of Cochlefelis differing from the genotype, C. spatula (types compared), in being of more robust form, having the anterior nostrils closer together than the posterior, in having a few granular teeth on palate, and a better developed vertical system, besides its smaller predorsal shield, free orbital margin, inter- orbital wider than mouth, nine gill-rakers on lower half of first branchial arch, conspicuous vent, adipose dorsal fin short and over middle of anal, and base of anal less than half Fig. 4. Catfish, Cochlefelis colcloughi. Holotype, Croker Id., Northern Territory. G. P. Whitley, del. Here figured from the holotype of the species kindly loaned by the Director of the Queensland Museum. The vomerine dentition was not men- tioned by Ogilby; he evidently had difficulty in finding it, judging from the way the type has been cut about. There appears to be a patch of granular teeth far back on each side of the palate. Cochlefelis colcloughi is also allied to Hemipimelodus papillifer Herre, 1935, from the Sepik River, New Guinea, but has fewer anal rays, more flattened head, base
