which can only be ascertained by a direct comparison 
of the Sydney fish with my description*, the specific name 
fulvipes would be superseded by cribrosus Kner, an alter- 
native name given by that author to his fish, and in that 
case the synonymy of the species would stand as follows :— 
EXONAUTES CRIBROSUS. 
Exocetus unicolor’? C.V.; Kner, Reise Novara, Fische 
p- 325, 1867: Sydney. 
Exocetus cribrosus Kner, ibid., p. 326. Suggested new name 
should the species prove distinct from EF. wnicolor. 
Exocetus dovi Ogilby, Mem. Austr. Mus., No. 2, Lord 
Howe Island, p. 71, 1889. Not H. dowti Gill, 1863= 
E. rufipinnis Cuvier & Valenciennes, 1846. 
Exonautes rondeletii Waite, Rec. Austr. Mus., v, 1904, pp. 
156 & 195: Admiralty Islets. Not Hxocetus rondeletii 
Cuvier & Valenciennes, 1846. 
Exonautes unicolor Jordan, Study of Fishes, i, fig. 226 
& u, p. 213, 1905. Not Hxocetus unicolor Cuvier & 
Valenciennes, 1846, which is a Cypsilurus. 
Exonautes fulvipes Ogilby. Supra. 
PTENONOTUS gen. nov. 
This genus is proposed for the accommodation of 
Exocetus cirriger Peters,t and differs from Cypsilurus 
and Hxonautes, between which it should be placed. in the 
elongated hemirhamphiform body, the permanency of the 
submental appendage, which is of great size and divided 
distally into numerous fine cutaneous filaments, and in 
the high, pointed dorsal fin, which extends, when depressed,. 
far beyond the base of the caudal. (rrpvés, winged ; 
votos, back.) 
Hab. China Sea. 
* Tf, as I presume, Kner’s Novara specimen from Sydney is deposited’ 
in the collection of the Imperial Museum, Vienna, Dr. Steindachner might. 
set at rest for ever the identity of Hxonautes eribrosus by making the: 
suggested comparison.
