AMPHIPRION 11 



Dorsal X, 15 to 17; anal II, 12 to 15; scales in lateral series 

 45 to 52 ; with tubules 33 to 42 ; between lateral line and origin 

 of dorsal 8 or 9; between lateral line and vent 19 to 23. 



Body oblong, the dorsal and ventral outlines equally elevated, 

 the latter more evenly arched, the deepest part of body at origin 

 of dorsal fin 1.9 to 2.1 in length; head 3 to 3.3; depth of caudal 

 peduncle 5.6 to 6.5. The evenly convex interorbital 2.7 to 3.1 

 in length of head; the circular eye 3.1 to 3.6; the rounded 

 snout 2.8 to 3.2, shorter than maxillary, which is contained 2.5 

 to 2.8 in head. Mouth very oblique, lower jaw slightly pro- 

 jecting, the maxillary ending posteriorly below front edge of 

 orbit. Preorbital terminating in a strong spine, which is pre- 

 ceded by a shorter one; orbital serrated; opercle with radiating 

 ridges which end in spines. 



Head naked on snout, orbital ring, interorbital space, and 

 posterior limb of preopercle; base of vertical fins covered by 

 a low sheath of scales. Third and fourth dorsal spines highest; 

 the last spine higher than the one preceding but lower than 

 first dorsal ray. Caudal lunate; both pectoral and ventral fins 

 extending to vent. 



Alcoholic specimens either brownish or blackish, very much 

 darker posteriorly and above toward the fins, with three milk 

 white, black-edged transverse bands; the first from nape to 

 interoperculum, touching hind edge of orbit ; the second from the 

 last two dorsal spines and the first two dorsal rays to origin 

 of anal, not extending upward into margin of dorsal fin; the 

 third on posterior half of caudal peduncle. Caudal, anal, ven- 

 tral, and pectoral yellow, and in some cases the last three fins 

 edged with black. In other specimens the anal is chocolate 

 brown, narrowly edged with white. 



Here described from thirty-three examples, varying from 19 to 

 89 millimeters in length. They were collected at the following 

 places: Calapan, Mindoro; Tablas Island; Guindulman, Bohol; 

 Dumaguete, Oriental Negros; Cagayan de Misamis and Zam- 

 boanga, Mindanao; and Bungau, Sibutu, Sitankai, and Tango 

 Islands, Sulu Archipelago. Three females, each 79 millimeters 

 in length, collected at Calapan in January, 1923, are about ready 

 to spawn. The Bureau of Science collection has two examples, 

 collected by Mr. Alvin Seale at Hongkong. 



This species has been previously reported from the Philip- 

 pines by Bleeker. Cartier's account of a specimen from Bohol 

 reveals the identity of his species with Amphiprion polymnus.
