Figure 3. — Holotype of Symphysanodon maunaloae (USNM 204389, formerly HBL uncataloged) , 



69 mm. SL. 



S. maunalose, and in part to S. katayamai; dis- 

 tribution referring in part to S. typus, in part 

 to S. maunaloae, and in part to S. katayamai) . 



DIAGNOSIS 



Body slender, the depth 21.3 to 25.8 percent 

 SL. First pelvic soft ray well produced in a few 

 specimens, but only slightly produced in most 

 (not extending to anal fin). Anal fin short, 

 length of depressed anal fin ca. 24.0 to 29.2 per- 

 cent SL. Caudal fin deeply forked, both lobes 

 produced, but apparently never produced into 

 excessively long filaments. Anal soft rays 7. Gill 

 rakers 9 to 11 + 22 to 26— total 31 to 37. Pored 

 lateral-line scales 43 to 47. 



DESCRIPTION 



Maxillary extending posteriorly to about 

 middle of eye or a little beyond. Length of upper 

 jaw contained in length of mandible 0.93 to 1.09 

 times. Interorbital region flattened. No teeth 

 apparent on vomer, palatines, or pterygoids. 

 Small serrae on vertical limb of preopercle, hori- 

 zontal limb almost smooth or with a few serrae, 

 rpainly near angle; a spine or spinelike process 

 at angle (spine or spinelike process often ser- 

 rate). No scales on anteriormost part of snout; 

 apparently a few scales in midline of anterior 

 part of gular region in a specimen of 51 mm. SL 

 (no other indications of scales in gular region of 

 this specimen), scales not apparent in gular 

 region of other specimens; frequently one to 

 several scales present on membrane between the 



third and fourth branchiostegal rays, no other 

 scales apparent on branchiostegal membranes. 



Counts 



Frequency distributions for the following 

 counts are given in tables 2, 3, and 4. Dorsal-fin 

 rays IX, 10 (IX, 9 on three specimens). Anal- 

 fin rays III, 7. Pectoral-fin rays 15 to 17. Gill 

 rakers 9 to 11 + 22 to 26 — total 31 to 37. Pored 

 lateral-line scales 43 to 47. Sum of total number 

 of gill rakers on anterior gill arch plus number 

 of pored lateral-line scales of individual speci- 

 mens 76 to 81, 83. 



Measurements 



Ranges of selected measurements are presented 

 in percentage of standard length followed by the 

 value for the holotype of S. maunalox in paren- 

 theses. Length of head 32.0 to 35.6 (34.0) . Depth 

 of head 19.5 to 24.0 (21.0). Length of snout 6.4 

 to 8.2 (7.3). Horizontal diameter of fleshy orbit 

 10.3 to 14.0 (ca. 12.8). Width of suborbital ca. 

 0.6 to 1.0 (0.6) . Height of cheek 3.8 to 5.6 (4.2) . 

 Length of upper jaw 12.5 to 15.1 (14.7). Length 

 of mandible 12.5 to 15.7 (14.5). Width of bony 

 interorbital 7.3 to 9.3 (8.3). Depth of body 21.3 

 to 25.8 (23.7). Least depth of caudal peduncle 

 9.6 to 11.9 (10.5). Pectoral fin usually reaching a 

 vertical through base of first or second dorsal 

 soft ray; length of longer pectoral fin 24.3 to 

 28.1 (26.1). Pelvic fin usually not extending to 

 anal fin, but the first pelvic soft ray produced at 

 least as far as middle of anal fin in several speci-
