The 35 specimens taken in the Cobb pelagic 

 trawl at station 90.90 indicate that this species 

 may occur in large schools at least in certain areas. 

 It has been identified from a large number of rou- 

 tine CalCOFI plankton-tow stations, but only one 

 or a few specimens had been taken in a single tow. 

 Lestidium elongatum Ege is undoubtedly a junior 

 synonym of this species (E. H. Ahlstrom and 

 R. R. Rofen, personal communications). The 

 specimen reported as Macroparalepis sp. by Harry 

 (1953 : 186, fig. 5) is a young stage of L. ringens.

This species has generally been designated under 

 the name of Notolepis coruscans (Jordan and Gil- 

 bert) (R. R. Rofen, personal communication). 

 Our relatively small and mostly damaged speci- 

 mens have lower numbers of anal fin rays (a max- 

 imum of 26 or 27) than other eastern Pacific 

 specimens that have been reported (A. 29 to 33) 

 (Harry, 1953:210).

 72 mm. ; 90.150, C6208, (73) ca. 61-82 mm. ; 90.200, H6204, 

 (1) ca. 27 mm. 



This species is more widespread in the eastern 

 Pacific, and perhaps more gregarious, than pre- 

 viously shown. The larvae have been taken in 

 offshore plankton-net collections, but most catches 

 had only one or two individuals. Most of the 

 records reported by Ege (1957:94-95) are of 

 single specimens ; the maximum at one station was 

 nine. The 73 specimens taken at station 90.150 

 in September by the Cobb pelagic trawl indicate 

 that the species is at times locally abundant. 



The above records extend the known range of 

 the species. Previously Ege (1957:68) had re- 

 corded it from northeast of the Galapagos Islands. 

 Harry (1953:231) placed this species in the 

 genus Stemnosudis Harry, but our specimens, 

 and apparently those of Ege, possess characters 

 more like those of Macroparalepis. The 135-mm. 

 specimen, one of the largest specimens of the species 

 to be recorded, has the anterior lateral line scales 

 only slightly higher than long (1.17X) , the nostrils 

 well in advance of a vertical line through the 

 posterior end of the maxillary, D. 8, A. 38, verte- 

 brae 96 total and 33 prehaemal, and the anterior 

 peritoneal pigment spots coalesced (about 14 were 

 present) .

Chapman (1939:530) described this species in 

 the new genus he proposed, Neoscopelarchoi-des. 

 Marshall (1955:314) used this generic name rather 

 than Benthalbella. Zugmayer 1911. These two ge- 

 neric names, however, are synonymous, and under 

 the current International Rules of Zoological 

 Nomenclature, Benthalbella has priority (E. H. 

 Ahlstrom, personal communication).
