dorsal and pectoral origins and a little less than one-fourth of standard length. Nasal rosette 

 round. Three (4) AOp over anal base. 



Five to 7 supracaudal and 4 to 6 infracaudal luminous glands are evident on specimens of 

 about 20 mm SL. 



Size: To about 40 mm. 



Least depth of capture: At surface at night. 



Distribution: The range of C. breuirostris, known primarily from the northwestern Pacific, 

 extends in a narrow band from about the North Tropical Convergence to the southern bound- 

 ary of the North Pacific Drift (Fig. 74). 

 Discussion 



C. breuirostris is so very similar to C. nigroocellatus of the North Atlantic Ocean that it 

 may be at best only a subspecies. Until a more detailed comparison is made I feel it best to 

 retain Becker's species. 



Centrobranchus nigroocellatus 



(Gunther, 1873) 



Fig. 76 — Centrobranchus nigroocellatus. From Becker (1964a, p. 59, fig. 24). 



Description 



D. 10 (9-11); A. 18 (17-19); P. 15 (14-17); AO 5 (4-7) -H 9 (8-11), total 15 (13-17); vertebrae 

 36 (35-37) (based on Atlantic specimens). 



Snout length about equal to least depth of caudal peduncle, over half the orbital diameter. 

 Greatest body depth a little less than one-fourth of standard length. Nasal rosette round. 

 Three or 4 AOp over anal base. 



Six (5-7) supracaudal and 5 (3-6) infracaudal luminous glands evident on specimens as 

 small as 20 mm. 



Size: To about 40 mm. 



Least depth of capture: At surface at night. 



Distribution: The range of C. nigroocellatus appears to lie in the Indian Ocean, with one 

 occurrence noted in the southwestern Pacific at 29°52' S, 172°00' W (Becker, 1964a). It has not 

 yet been reported from the eastern Pacific (Fig. 74).
