rather close before pectoral. Scales present on trunk and tail, very 

 small on predorsal, chest and breast, large on prepectoral and on 

 tail posteriori}'. Tvro dorsals, first of 6 slender spines of which first 

 prolonged as filament, which would reach base of last dorsal ray, 

 and soft fin with spine and 28 rays. Anal little shorter than soft 

 dorsal, with spine and 24 rays. Caudal rather large, ends posteriorly 

 in median point (now damaged). Pectoral short, low. Ventrals 

 well separated, inserted little before pectoral base, slender, moderate. 



I name this genus for an exquisite little eleotrid, with its second 

 and third dorsal spines ending in a prolonged filament ; peculiar f acies 

 of head with veiy short snout, large eye and strong jaws, and long 

 soft dorsal and anal; also a color pattern of greatly pleasing and 

 contrasted design. 



(vrina, ihTead-{-Eleotns', with reference to the elongated, filamentous, 

 first doisal spine.) 



NEMATELEOTRIS MAGNIFICUS, new species 



Depth 5; head 4%, width 2. Snout 5 in head from snout tip; eye 3, 

 greatly exceeds snout, equals interorbital ; maxillary extends below 

 first third of eye, length 2i/^ in head from snout tip; teeth strong, 

 conic, sharp pointed, about 20 in each jaw; interorbital 3, low, de- 

 pressed concavely. Gill opening restricted, lateral, length 2% in 

 head from snout tip, with rather broad isthmus exposed. 



Scales 108 + 10 in axial lateral series; 27 transversely above anal 

 origin. Scales very small and crowded on front sides of back, chest, 

 breast and belly. Caudal base scaly, otherwise fins naked. Scales 

 with 11 basal radiating striae; 8 to 12 rather large uniserial apical 

 denticles; circuh fine, obsolete apically. 



D. VI-I, 28, I, first spine prolonged filament so as to reach bas© 

 of last ray, fifth ray 11/^ in total head length; A. I, 24, i, eighth ray 

 1%; caudal 3I/3 in rest of fish, ends posteriorly in median point 

 (damaged) ; pectoral lyV in total head length, rays 17 ; ventral raj^s I, 

 5, fin 1 in total head length ; least depth of caudal peduncle 1%. 



Light brown generally, little paler to whitish on under surface of 

 head and belly. Iris gray-white. Dorsals and anals largely whitish, 

 long filament grayish. Soft dorsal with broad upper border gray 

 black, little above middle each membrane with large black blotch, 

 convex above and concave below so white of fin forms more or less 

 of ocellate ap|x;arance, also each membrane with basal whitish area 

 with 3 to 6 small dark gray round spots. Anal with lower border 

 gray black and then band made up of black ocellate spot on each 

 membrane. Caudal pale basally, blackish above and below, and 

 oblique black bar converging medially behind on each lobe. Paired 

 fins dull brown. 



The diagnosis is contained in the generic account.
