182 MEMOIRS OF THE CARNEGIE MUSEUM 



Head 2.5 in length ; depth 2.75 to 2.9 ; eye 3 in head, 8.5 to 9 in length to 

 hase caudal ; snout 4.7 to 4.9 in head ; interorbital 4.2 ; dorsal VI-I, 9 ; anal II, 

 16 or 17 ; scales 3-25-5. 



Body noticeably more elongate and thinner than in Archamia macropterus 2 

 (Bleeker) ; depth of caudal peduncle 2.3 in head ; profile straight to a point over 

 front of eye, the tip of the snout a very little upturned ; mouth large, upturned ; 

 maxillary 2.2 in head ; maxillary extending to nearly under middle of eye ; upper 

 lip on level with middle of eye; tip of lower jaw slightly projecting when mouth is 

 closed ; minute villiform teeth in jaws and on vomer and palatines ; no canines ; 16 

 gill-rakers on lower limb of outer arch, longer than the corresponding filaments, the 

 longest about 2 in eye ; preopercle finely denticulated about angle on both hinder 

 and lower margin ; operculum with a thin flat point, even with middle of eye, 

 and a little above it a second less prominent point ; scales ctenoid ; lateral line 

 apparently complete (some scales missing in all specimens) ; cheeks scaled ; origin 

 of spinous dorsal half-way between axil of soft dorsal and front of eye ; longest 

 dorsal spine 2.7 in head, first dorsal spine f second ; origin of anal a little in front 

 of that of soft dorsal ; ventrals 1.8 in head, their origin slightly in front of base of 

 pectorals; pectorals 1.4; caudal weakly emarginate. 



Color in spirits light straw, rather sparsely and faintly punctulated above on 

 head and body ; lower parts of sides and belly nearly plain ; a small but very dis- 

 tinct blotch at base of caudal, its diameter less than one-half that of pupil ; tip of 

 lower jaw dusky ; dorsals, caudal, and anal tinged with dusky ; no fin with dark 

 tip or edge ; no spot on shoulder. 



Described from six specimens from Takao, two to two and one-half inches long. 



This species seems to be well distinguished from Archamia macropteroides by its 

 slenderer form, smaller eye, different coloration, fewer punctulations tending to 

 form no pattern, and the prominent but very small caudal spot. The first 

 dorsal spine is little shorter than the second, which is also the case in Archamia 

 bleekeri Gunther (= Apogon macropterus Bleeker, not Kuhl & Van Hasselt). In 

 Archamia macropteroides the first spine is scarcely more than half the length of the 

 second. In Archamia bleekeri there is a distinct black blotch on the shoulder, as 

 well as at base of caudal. In Archamia macropteroides the caudal spot is much less 

 distinct, and the shoulder spot indistinct or absent. Archamia facata (Cantor) 

 has a smaller mouth and most of the other nominal species have fewer rays in the 

 anal fin. 



2 The specimen from Samoa called Archamia lineolata by Jordan & Seale should probably stand as Archamia 

 macropteroides. Archamia lineolata from the Red Sea with fourteen soft rays in the anal and with twelve dark cross 

 streaks must be different and also distinct from the present species.
