Neohythites onacrops, Giinther, 'Challenger' Deep-sea Fishes, p. 102, 



pi. XX. fig. A. 

 NeohytJiites macrops, Alcock, Anu. & Mag. Nat. Hist., No^^. 1889, 



p. 38.5. 



Twenty specimens, varying in length from 4 to 8^ inches, 

 were taken at Station 115, 188 to 220 fathoms. 



18. Neobythites pterotus, Alcock. 



Neoh/thites pterotus, Alcock, Ann. & Mag. Nat. Hist. Sept. 1890, 

 p. 210, and Oct. 1890, p. 297. 



A very fine male specimen, 1 foot long, from Station 117, 

 1748 fathoms. It differs from the large female captured last 

 year in the Laccadive Sea in having the pectoral fin-rays very 

 much more prolonged — reaching to the tenth anal ray — and 

 spatulate at the ends. In the female the pectoral fin-rays 

 reach only to the first anal ray. 



Saccogaster, Alcock. 



19. Saccogaster maculata^ Alcock. (PI. VII. fig. 3.) 



Saccogaster macvlatus, Alcock, Ann. & INIag. Nat. Hist., Nov. 1889, 

 p. 389. 



An adult male specimen, just over 3^ inches long, from 

 Station 120, 240 to 276 fathoms. The male has a large 

 bilobed postanal papilla, and into the sulcus between the 

 lobes the seminal duct opens. The female, it now appears 

 from a reexamination of the type described in 1889, has the 

 distended ovaries full of developing embryos, so that we now 

 know Saccogaster maculata to be a viviparous fish ; and we 

 may conclude that the postanal papilla is an intromittent 

 organ of copulation.
