122 ^4 Collection of Fishes from S>amoa. 



Color when fresh in alcohol, the front half of entire body is deep blackish brown, 

 hind portion white, line of demarcation very striking or exactly midway between eye 

 center and caudal base. Pectoral base and dorsal jet-black. Iris blackish-brown, 

 golden circle around black pupil. 



Length 75 mm. Pago Pago. 



Another with same locality shows: Head 3.16; depth 1.87; D. XII, 14; A. II, 13; 

 14 tubes in upper arch of lateral line; snout 4 in head; eye 2.5; maxillarj^ 3.25; inter- 

 orbital 2.25; length 60 mm. 



Concerning C. dimidialus, Jordan and Scale state; "It is very close to our Chromis 

 isonielas, but according to the figure by Dr. Giinther, and the description of Dr. Klun- 

 zinger, the posterior boundary of the black area is at the front of the anal fin." Turn- 

 ing to Giinther 's figure of Heliastes dimidiatus,^ one finds such is not the case, as 

 Giinther shows the dark anterior area extending almost to the caudal peduncle, at 

 least over a good portion of the soft dorsal and certainly over more than half of the 

 anals. No dark pectoral blotch is indicated, though Giinther says that the pectoral 

 base is black. It thus appears that his figure represents a variation of C, dimidiatm, 

 and it is quite likely C. isomelas is simply another variation. Klunzinger says" that 

 the dark anterior color extends to origin of anal, bases of pectorals and ventrals black, 

 pectoral hyaline. He mentions only one example, 60 mm. long, and states that its 

 caudal has elongate points. 



LABRIDJE. 



Platyglossus notopsis (Valenciennes). 



Tliree young examples from Pago Pago, quite unlike the adult in coloration. In 

 alcohol our specimens are generally dull brown. Five longitudinal bands, expanded 

 medially, each bordered broadly with blackish-brown so as to form 10 bands all 

 together. Bands on head much narrower and pale areas thus wider. On trunk inter- 

 vening dark areas of each pair of dark bands mottled or blotched obscurely darker. 

 Dorsals and anals black. Middle of spinous dorsal with large black ocellus, edge 

 narrowly whitish, equal to 1.5 eye diameters. Caudal base with blackish bands 

 extending short space, then end abruptly, rest of fin white. Pectoral with dusky base, 

 fin otherwise gray-white. Ventral dusky. Iris slaty-brown. Largest example 44 

 mm. Smaller examples show pale brown, general color paler or more whitish, also 

 pale bands much broader. In very young each dorsal white, with 2 black blotches, 

 side wth 2 broad longitudinal blackish bands and parallel short band on back and 

 breast. Also bands end on caudal base as black blotch to each caudal lobe. Median 

 blackish band on head above and another below upper forks at interorbital to form 

 band each side of back, and lower extends back to join abdominal band of each side 

 behind. Otherwise coloration whitish or pale. 



Also, small example from cove just south of Aua village. 



Cheilinus fasciatus (Bloch). 

 Young example from cove just south of Aua village. 



SCARICHTHYIDiE. 



Callyodon rubro-violaceus (Steindaclmcr). 



Head 2.33; depth 2.8; D. IX, 10; A. Ill, 9; scales 19 in upper arch of lateral line, 



5 in lower section to caudal base and 2 more on latter; 1 scale above lateral Une and 



6 below; snout 3 in head; eye 4.25; mouth 6.5; interorbital 3. Three rows of scales 

 on cheek, of which lower row on preopercle limb. Body elongately ellipsoid, com-
