1. Murcena monostigma. 



Tall as long as or shorter than the body ; length of head 

 3;^ to 3| in that of the trunk. Anterior nasal tube short ; 

 ])03terior nostril with edge raised to form a distinct but short 

 tube ; eye situated above middle of mouth, its diameter less 

 than ^ the length of snout ; cleft of moutli ^ the length of 

 head or a little more; jaws equal anteriorly ; teeth with 

 serrated edges, uniserial, canine-like on the sides of the jaws ; 

 12 to 16 teeth forming the mandibulary series on each side. 

 Dorsal origin above gill-opening ; fin low, above the vent 

 measuring less than \ the depth of the body. Brownish, 

 sometimes with irregular yellowish spots; a single deep- 

 black spot immediately behind the eye ; posterior nasal tube, 

 2 or 8 pores below the eye and sometimes pores on the lower 

 jaw situated in white spots. 



Three specimens, 450 to 550 mm. in total length, from 

 Tahiti and Raiatea [Godeffroy Mas.). 



Allied to M. moluccensis, Bleek., in which the posterior 

 nostril is not tubular, the teeth on the sides of the mandible 

 are smaller and more numerous, forming a regular series, 

 and there is no black spot nor white pores on the head. 



2. Gymnomurana poJt/spila. 



Tail slightly longer than body; length of head 11 in the 

 total length. Posterior nostril not tubular; eye nearer to 

 angle of mouth than to end of snout, its diameter ^ the length 

 of snout ; cleft of mouth ^ the length of head ; jaws equal 

 anteriorly ; teeth in jaws biserial ; gill-opening on middle of 

 side. Reddish, with large dark brownish or purplish spots 

 forming 2 or 3 irregular series on each side ; snout and 

 anterior half of lower jaw pale yellow. 



A specimen of 182 mm. from Tahiti [Godeffroy Mas.). 



A much larger fish (720 mm.) from Zanzibar {Play/air) 

 probably belongs to this species. It is labelled G. tigrina, 

 but differs from that species in the less slender form and 

 in having the tail nearly equal in length to the body. The 

 rim of the posterior nostril is raised. The colour is faded, 

 but apparently the spots and red ground-colour ceased just 

 behind the eye and in the middle of the lower jaw. 



3. Gymnomurcena fasciolata. 



Tail longer than body ; length of head 8^ in the total 

 length. Posterior nostril tubular, the tube longer than that
