FISHES OF THE PHCENIX AND SAMOAN ISLANDS 23 



flattened tips, somewhat molar-shaped, especially on the vomer. The 

 intermaxillary plate has three large teeth in the midline with a row 

 of smaller ones around them; the maxillary has two rows of 

 small teeth anteriorly, the outer one about twice longer than the 

 inner row; vomer with two rows of teeth; dentary with a patch of 

 teeth anteriorly at tip or two irregular rows, the outer row^ con- 

 tinuing posteriorly and composed of about 13 or 14 teeth ; gill open- 

 ings a horizontal slit a little above the midaxis of the head. Posterior 

 nostrils above front of each eye have a raised, fringed rim, sometimes 

 white; six pairs of pores on lower jaw and five pairs of pores above 

 upper lips, two pairs of pores on front of snout between anterior and 

 posterior nostrils. 



Color plain brown; the edges of dorsal and anal fins wliite, their 

 basal three-fourths or four-fifths brown; snout either all w'hite or 

 just around the pair of pores at upper front of snout, the tip of snout, 

 including tubular nostrils, brownish; upper lip wliite broken under 

 eye with two brownish lines more or less inclosing some wliite, these 

 lines extending on the side of the lower lip to form a brownish 

 blotch, the rest of the jaw plain pale or white except for very tip, 

 which has brownish pigment on the lip; the pale lower part of the 

 head gradually changes to brown on the throat. In a specimen 

 44 mm. long there are tw^o irregular white rings on head behind eye. 

 and a pale area just in front of the gill of)enings; in a 39-mm. speci- 

 men only the tip of the snout is pale, and the edges of the median 

 fins are pale. 



Remarks. — This new species differs from all other species of eels 

 referred to the genus Echidna in coloration, chiefly the pale areas 

 around the head and the white bands around the edges of the median 

 fins. 



Named leucotaenia in reference to the white bands around the edges 

 of the median fins.

Anarchias is based on Jordan and Stark's statement that "the 

 dorsal is developed as usual, but entirely lacking the anal fin." My 

 examination of the type, however, indicates that they were in error. 

 There is no dorsal fin as shown in fig. 9, p. 205, by Jordan and Seale, 

 only a fold of skin, without rays. I have dissected this fold of skin 

 on both A. aUardicei and A. hnighti, and no rays of any sort occur. 

 If Anarchias stands it will be on another character, perhaps on the
