Material.— CAS 236407 (95.2 mm SL); HEPD-021, beam trawl in 132-172 m. 
Remarks. — A common, widely distributed species in the Indo-West Pacific from southern Japan to eastern 
Austraha and east to Samoa, and Indian Ocean to South Africa and Red Sea, in depths of 80 to 100 m over 
rocky bottoms. 
Apogonidae (Cardinalfishes) 
Jaydia carinatus Cuvier, 1828 (Fig. 119) 
Material.— CAS 235746 (100.0 mm SL, DC-1452); HEPD-021, beam trawl in 132-172 m. CAS 235571 
(92.0 mm SL); CAS 235789 (88.4 mm SL); HEPD-022, otter trawl in 115-144 m. 
Remarks. — Lives over muddy bottoms; most often taken in trawls to about 50 m. Attains at least 15 cm TL. 
Known from Japan south to Taiwan, Hong Kong and the Philippines; also recorded from northwestern 
Austraha. The HEPD specimens had a totally clear A, lacking blackish distal mai'gin; the upper limb of its 
first gill arch has one or two developed rakers, although the upper of these was considerably smaller than 
the one nearest the angle. 
Jaydia cf. poecilopterus Cuvier in Cuvier aud Valeucieuues, 1828 (Fig. 120) 
Material.— CAS 236504 (2, 50.5-59.4mm SL, DC-1465); HEPD-021, beam trawl in 132-172 m. CAS 
236506 (16, 30-50 mm SL); HEPD-022, otter frawl in 115-144 m. 
Remarks. — This species lacks the fm coloration of closely related species of Jaydia (black edging on anal 
fin, black spot on soft dorsal fm of J. carinatus; dorsal half of spinous dorsal fin black and thin dark stripes 
on soft dorsal fm of J. poecilopterus). 
Ostorhinchus cf. cheni Hayashi, 1990 (Fig. 121) 
Material.— CAS 236505 (52 mm SL, DC-1511); HEPD-028 in 115-124 m. 
Remarks. — Ostorhinchus cheni is a deepwater western Pacific species that is very similar in coloration to 
CAS 236505; however, O. cheni has a fainter snout stripe and lacks a fine black margin on its caudal fin. 
We follow Thomas H. Fraser {in litt., October 2013) in recognizing Ostorhinchus and Jaydia as valid gen¬ 
era. 
Epigonidae (Deepwater Cardinalfishes) 
Epigonus ctenolepis Mochizuki aud Shirakihara, 1983 (Fig. 122) 
Material.— CAS 235796 (160 mm SL, DC-1443); HEPD-019, beam trawl in 541-636 m. 
Remarks.— This HEPD specimen is only the fourth recorded of this species and the first from the Philip¬ 
pines (others taken off southern Japan) as well as the largest known. It agrees well with characters given 
by Okamoto and Fukui (2011) with the exception of having a GR count of 6+1+15 (22 total) vs. 24-25 
total and 8 pyloric caeca (vs. 9-11).
