and Van Duzer 1980). This species has a wide geo- 

 graphic distribution in tropical and subtropical 

 waters of all three major oceans of the world. 



Melanocetus murrayi Giinther 1887 



Materia/.— LACM 36114-1, 68 mm SL, stn 66; 

 LACM 36113-1, 82 mm SL,stn 71; LACM 36115-1, 

 84 mm SL, stn 102. 



Melanocetus murrayi is represented by three 

 females in the Alpha Helix collections (Pietsch 

 and Van Duzer 1980). This species has a wide 

 horizontal distribution in the Atlantic and Pacific 

 Oceans, but is apparently absent from the Indian 

 Ocean. 



Melanocetus sp. 



Ma^ena/.— Males: LACM 36067-2, 13.5 mm SL, 

 stn 23; LACM 36116-1, 21.5 mm SL, stn 84; LACM 

 36032-4, 22.5 mm SL, stn 110. 



These male specimens could not be satisfactor- 

 ily identified to species (Pietsch and Van Duzer 

 1980).

Melanocetus Gunther 1864 



Key to Females of Species of 

 Southeast Asian Melanocetus 



lA. Anterior margin of vomer nearly straight; 

 width of pectoral fin lobe 10.7-17.8% SL; 



number of lower jaw teeth 32-78 



M.johnsoni Gunther 



IB. Anterior margin of vomer deeply concave; 

 width of pectoral fin lobe 6.1-8.99f SL; 



number of lower jaw teeth 46-142 



M. murrayi Gunther 



Melanocetus johnsoni Gunther 1864 



Materia/.— LACM 36076-3, 14 mm SL, stn 26; 

 LACM 36059-3, 15 mm SL, stn 103; LACM 

 36032-3, 15 mm SL, stn 110; LACM 36076-5, 17 

 mm SL, stn 26; LACM 36074-2, 18 mm SL, stn 120; 

 LACM 36033-2, 36 mm SL, stn 88. 



Six specimens of M.johnsoni were collected by 

 the Alpha Helix in 1975, all of which were included 

 in a recent revision of the Melanocetidae (Pietsch 



Himantolophus Reinhardt 1837 

 Himantolophus sp. 



Matena/.— Female: LACM 36038-3, 2(12.5-14 mm 

 SL), stn 87. Males: LACM 36091-4, 16 mm SL, 

 stn 142; LACM 36057-4, 19 mm SL, stn 93; LACM 

 36075-4, 4(19.5-21 mm SL), stn 121; LACM 

 36074-3, 21 mm SL, stn 120; LACM 36040-3, 27.5 

 mm SL, stn 27; LACM 36046-8, 2(29.5-33 mm SL), 

 stn 97; LACM 36124-1, 31 mm SL, stn 112. 



Thirteen specimens o^ Himantolophus were col- 

 lected by the Alpha Helix from the Banda, Coram, 

 and Halmahera Seas. The genus is cosmopolitan 

 in all three major oceans of the world (Bertelsen 

 1951), yet no adult females have been collected in 

 the immediate area. These males and larval 

 females could not be identified specifically.
