 The specimens from Costa Rica referred to P. sphenoiis, one of ^^■hich is figured 

 (Tab. XIIl. fig. 2), appear to differ from P. sjjhenojjs in the greater length of the 

 anterior dorsal rays and in the presence of a dark spot at the base of the dorsal fin. 

 This species seems to be the one described by Steindachner as Girca-diiin.H enncamis.
