FISHES— REGAN. 15 



EXOCOETIDAE. 



8. Exocoetus spilonotopterus, Bleek. 



Macrorhamphosidae. 



Notopogon, Regan. 

 Notopogon, Regan, Ann. Mag. Nat. Hist. (8) xm, 1914, p. 14. 



This genus is distinguished from Macrorhamphosus by the deeper form, the dorsal 

 fins continuous at the base, the strong second spine followed by five nearly 

 equidistant and gradually decreasing in length backwards, and by the development of 

 a patch of bristles on the nape in the adult fish. From Centriscops it differs in the 

 last character and in having only three well-developed plates in each dorso-lateral series. 



9. Notopogon lilliei, Regan (PL xn, fig. 4). 



Cfiilrisciipx hiuiu'rosus (non Richards) McCulloch, "Endeavour," Fish. p. 24, fig. 5, and pi. ix 



(1911). 

 Notopogon lilliei, Regan, Ann. Mag. Nat. Hist. (8) xm, 1914, pp. 14, 20. 



Depth of body '2f. in length, length of head 2. Distance from base of dorsal spine 

 In vent L| in that from head to caudal fin. Diameter of eye 3g in length of snout, 

 a little more than postorbital part of head, twice depth of cheek. Interorbital space 

 convex, with blunt median ridge ; width •] diameter of eye. Back slightly, belly more 

 st rongly convex. Two series of bony plates on each side of back ; only three large plates 

 in each series; ventral plates keeled in front of, spinate behind pelvic fins. Dorsal vn, 

 14, the two fins continuous; second spine strong, serrated, inserted above middle of 

 anal fiu, its length a little more than ^ distance from operculum to caudal fin. Anal 19. 

 Pectoral as long as head without snout. Caudal truncate. 



A single specimen, 125 mm. in total length, from New Zealand, caught by 

 fishermen ; the species is also known from the south coast of Australia ; it is named 

 after Mr. D. G. Lillie. 



10. Notopogon xenosoma, Regan (PI. xn, fig. 5). 



Notopogon xenosoma, Regan, Ann. Mag. Nat. Hist. (8) mi, 1914, pp. 14, 20. 



Body elevated, the distance from base of dorsal spine to vent a little greater than 

 that from head to caudal fin. Head 2^ in the length. Diameter of eye a little longer 

 than postorbital length of head, f, length of snout, twice depth of cheek. Interorbital 

 space flat, its width -£- diameter of eye. Upper profile with a moderate hump ; belly 

 convex. Only three large plates in each dorso-lateral series ; last of dorsal series bearing 

 a spine ; venf ral plates spinate : a pair of spines at posterior end of lower jaw ; a patch of 

 scales behind dorsal hump modified into short bristles. Dorsal VII, 15, the two fins sub- 

 continuous ; second spine rather slender, serrated, inserted above caudal peduncle, its 

 length | distance from operculum to caudal. Anal 17. Pectoral as long as head 

 without snout. Caudal truncate.
