Coryphaenoides cf. leptolepis ( Günther 1877)  

( Fig. 2 View FIGURE 2 K)

Material examined. One specimen: MNRJ 26899 (1, 302.0 mm), AG, ASTRO 2003021301.

Distribution. Collected from off Rio de Janeiro, at depths from 1071 to 1205 m. The type locality of Coryphaenoides leptolepis   is Pernambuco, Brazil ( BMNH 1887.12.7.109; 9 °05’ S, 34 ° 50 ’ W), but specimens from other localities in the Pacific were also used: Yokohama ( BMNH 1887.12.7.111), and mid-Pacific ( BMNH 1887.12.7.132). Günther (1887: 144) restricted its distribution to Brazil, reallocating the other specimens to Macrurus liocephalus Günther, 1887   , and Marshall (1973 b) designated the lectotype ( Eschmeyer 2010).

Remarks. Coryphaenoides leptolepis   is being reported from a badly preserved specimen with a broken tail, body scales lacking, and the opercular region mostly destroyed on both sides. Comparison between our specimen and data available in literature ( Günther 1887; Marshall 1973 b; Cohen et al. 1990) indicated a few meristic differences: pelvic-fin rays 7 (vs. 9), first dorsal-fin rays 11 (vs. 10), and length of pelvic-fin filament 60 % in head length (vs. 96 %). Our specimen, however, agrees with the illustration provided by Günther (1887, plate XXXI) by having the snout naked with enlarged pores. Divergence in the number of pelvic-fin rays suggests that this can be a different species from C. leptolepis   , but more specimens are needed for a conclusive identification.
