MaAcRORHAMPHOSIDAR, 
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 (PI. xu, fig. 4). 
Centriscops humerosus (non Richards) McCulloch, “ Endeavour,” Fish. p. 24, fig. 5, and pl. 1x 
(1911). 
Notopogon lillie’, Regan, Ann. Mag. Nat. Hist. (8) xt, 1914, pp. 14, 20. 
Depth of body 22 in length, leneth of head 2. Distance from base of dorsal spine 
to vent 12 in that from head to caudal fin. Diameter of eye 33 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 
strongly convex. Two series of bony plates on each side of back ; only three large plates 
in each series ; ventral plates keeled in front of, spimate behind pelvic fins. Dorsal v1, 
14, the two fins continuous ; second spine strong, serrated, inserted above middle of 
anal fin, its length a little more than $ distance from opereulum 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 wenosoma, Regan (Pl. x1, fig. 5). 
Notopogon xenosoma, Regan, Ann. Mag. Nat. Hist. (8) xm, 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, ? length of snout, twice depth of cheek. Interorbital 
space flat, its width 2 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 ; ventral plates spinate ; a pair of spines at posterior end of lower jaw ; a patch of 
scales behind dorsal hump modified into short bristles. Dorsal vi, 15, the two fins sub- 
continuous ; second spine rather slender, serrated, inserted above caudal peduncle, its 
leneth # distance from operculum to caudal. Anal 17. Pectoral as long as head 
without snout. Caudal truncate.
