GENUS ENTOMACRODUS — SPRINGER

was not noted, nor was sexual dimorphism of dorsal fin ray counts 

 noted in specimens from other localities, but I do not consider my 

 data conclusive. 



Nomenclature. — Bleeker based his description of Salaiias decussa- 

 tus on four specimens, 51-128 mm (total length?), from Biliton and 

 Sangir Islands. There are only four specimens, RMNH 4778, from 

 Biliton and Sangir Islands in the Leiden museum. These specimens 

 are approximately 40, 51, 105, and 127 mm SL, which indicates a 

 possible discrepancy in the measurement of the largest specimen 

 (a specimen 40 mm SL would be about 52 mm total length, 128 mm 

 SL, about 155 mm total length). All four specimens are in poor 

 condition. I here designate the 105 mm (approximately 128 mm 

 total length) specimen from Sangir as lectotype. The lectotype, a 

 male, in better condition than the other specimens, has 16 predorsal 

 commissural pores; the paralectotypes have 10, 12, and more than 

 30 pores. The 127 mm paralectotype has two pores before each 

 anterior nostril; the lectotype and other paralectotypes have one pore 

 before each anterior nostril. 



Salarias aneitensis was described by Gunther from two dried speci- 

 mens, seven inches long, in the British Museum. These specimens are 

 no longer extant in the BMNH collections, apparently having been 

 lost during World War II when the BMNH types were removed from
