Counts for the ORB, OP, BR, IP, and PV 



series are as for other species of Argyripnus. 

 VAV + anterior AC: 19.5(2), 20(7). Middle 

 AC: 5(9). Posterior AC 12-14 (Table 1). 



Total vertebrae for 17 specimens (radio- 

 graphs obtained for 8 unexamined specimens) 

 ranged from 45 to 46: 15 precaudal + 30 

 caudal, 12 specimens (including holotype); 15 

 + 31, 3 specimens; 16 + 30, 2 specimens. 



McCulloch (1926) stated that A. iridescens 

 was so similar to A. ephippiatua that he sepa- 

 rated the two species with hesitation. The new 

 counts presented here for the two species indi- 

 cate that they should continue to be recognized. 



ARGYRIPNUS SVV. 



I have examined the following three speci- 

 mens of Argijnp)ius: (1) 51 mm SL, USNM 

 207984. RV Anton Bruun cruise 9, station 422, 

 Indian Ocean, lat. 6°51'N, long. 39°54'E, 19 

 November 1964, 100 m, midwater trawl. (2) 

 64 mm SL, SIO 69-19-10 (Scripps Institution 

 of Oceanography Circe Expedition, Celebes 

 Sea), lat. 06°00'N, long. 122°36'E, 21 April 

 1968, midwater trawl. (3) USNM 135402, 78 

 mm SL. This is the same Philippine specimen 

 treatedby Grey (1961). 



Measurements obtained on selected body 

 parts are given in Table 4. Counts that were 

 obtained on characters that show variation in 

 other species of Argyrip)ius are as follows 

 (values given are for the respective specimen 

 number). VAV + anterior AC photophores: 

 15, 16, 18. Posterior AC photophores: 10, 11, 

 12. Gill rakers: 4/4 + 11/11, 4/4 + 12/12, 

 2/4 + 9/12. There is no indication that the 

 right gill arch has been damaged on the third 

 specimen, but the higher count is taken to be 

 "correct." Pectoral rays: 15, 17, 15. Dorsal 

 rays: ca. 13, 12, 10. First anal rays: ca. 11, 13, 

 11. Second anal rays: ca. 9, 10, not available.
