526 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 40. 



Color in alcohol deep brown; a white stripe extending along back 

 from tip of snout to base of caudal; chin with a white spot; throat, 

 breast, and abdomen with a broad, white stripe, which is divided by 

 a dark median area of the body color ; caudal fin with two large, oval, 

 white spots on its basal third and with two narrow stripes beyond 

 these. 



In life the color is deep purple, the light stripes being brilliant, 

 orange red. The caudal is dark reddish brown, with bright orange 

 spots; the edge of the fin white. 



This description is of the type, Cat. No. 68226, U.S.N.M., a female 

 specimen 47 mm. long from Naha, Okinawa. Cotype, No. 21418, 

 Stanford University collection. 



The brood pouch of the male extends over fourteen osseus rings. 

 It is connected with the anal opening by a furrow, the edges of which 

 rise and merge into those of the brood pouch two rings in advance. 

 There is a median keel on the breast anterior to the pouch. 



Five specimens were secured measuring 28 to 48 mm. in length. 

 In swimming the movements are slow, the caudal is broadly expanded, 

 and the brilliant colors stand out in bold contrast against the gray 

 coral rocks of the pools.
