THE FISHES OF SAMOA. 203 



color; many of these streaks formed somewhat like an inverted Y; snout dark; a black spot at angle 

 of mouth; gill-opening not black; markings on head more diffuse; black folds along side of neck; 

 belly yellowish, marbled with brownish; fins colored like body, the anal with a narrow yellowish 

 margin; tip of tail with a narrow pale edge. 



209. Gyrnnothorax berndti Snyder. Hawaii. 



STR0PHID0N McClelland. 



210. Strophidon brummeri (Bleeker). East Indies. 

 Recorded by De Vis, Proc. Linn. Soc. X. S. W. 1884, 157, New Hebrides. 



ECHIDNA Forster. 



211. Echidna nebulosa (Ahl). Pus!. Tahiti; Wahia; Tonga; Borabora; Hawaii; Samoa; New 



Guinea; Shortland I.; Nukahiva (Seale); East Indies. 

 This widely diffused species is very common about Samoa, where about 40 specimens were taken. 

 It is relatively scarce about Hawaii. 



212. Echidna zebra (Shawj. Samoa; Hawaii; East Indies. 



This species, of a rich brown color, with narrow golden rings, is common at Samoa, where about 

 30 specimens were taken. It is rather scarce about Hawaii. 



213. Echidna polyzona (Richardson). Tahiti; Nukahiva (Seale); East Indies. 



214. Echidna zonophpea Jordan & Evermann. Hawaii. 



This species is close to Echidna polyzona, but with the other nominal species from Hawaii it seems 

 to differ in having the ground-color broken by mottlings. It may prove identical with Echidna 

 zonata. In Echidna polyzona, as figured by Bleeker, .the ground-color is plain dark brown as in 

 Echidna zebra, covered by rings of clear yellow. 



215. Echidna zonata Fowler. Hawaii. 



Echidna zonata Fowler, Proc. Ac. Nat. Sci. Phila., 1900, 496, Hawaii. 



Echidna vincta Jenkins, Bull. U. S. Fish Comm., xxn, 1902 (1904), 429, Hawaii. 



Echidna polyzona Fowler, Proc. Ac. Nat. Sci. Phila., 1900, 496, Hawaii; not of Richardson. 



Dr. Jenkins found this species rather common at Honolulu. We see no difference between the 

 species called zonata and vincta. 



216. Echidna psalion Jenkins. Hawaii. 



This species is known from a single example, evidently very close to E. vincta, if indeed vincta 

 and zonophiea and possibly obscura and trilor be not all color variations of the same species, Echidna 

 tritor. 



217. Echidna tritor Vaillant & Sauvage. Hawaii. 



218. Echidna obscura Jenkiits. Hawaii. 



219. Echidna leihala Jenkins. Pusi ' ai' aiuga. Hawaii. 



Numerous specimens taken recently at Hawaii leave little room for doubt as to the identity of the 

 nominal species, Echidna zonata, vincta, psalion, zonophsea, leihala, obscura with Echidna tritor. The 

 variations in the bands are very great, scarcely any two specimens being alike. 



220. Echidna trossula Jordan & Starks, new species. Samoa. 

 Munena nigra, Seale, Bishop Museum, 1901, 62, Guam; not o£ Day. 



Head 7.5 in entire length; depth 2 in head; snout blunt, 6.5 in head; eye 1.5 in snout; tubes of 

 anterior nostrils scarcely as long as diameter of pupil; cleft of mouth from tip of snout to angle 3.33 

 in head; teeth slightly movable except those in roof of mouth behind vomerine teeth; teeth in upper 

 jaw in a single row on each side, anteriorly rather blunt and conical, posteriorly sharper and smaller; 

 the one sort giving place to the other abruptly; a median row of two teeth anteriorly similar to those 

 of anterior outer row; behind these and remote from them, extending back in the roof of the mouth
