EEGAN— MARINE PISHES. " 223 



lobes more or less produced and pointed in the adult. Reddish brown ; edges of scales 

 lighter ; a bluish-white stripe from below eye to base of pectorals ; fins yellowish. 



This species was originally described from a small specimen of 47 mm. from. 

 Haddumati. Another of about the same size has since been received from Cargados 

 Carajos, and also some adult specimens (85 to 100 mm. in total length) collected l)y 

 Mr. F. W. Townsend at Kurrachee. These are included in the amended description 

 given al)ove. The relations of A. cooj^teri to its nearest allies may be shown thus: — 



Snout, iaterorbital region, and maxillary scaly ; lateral line curved, not forming an angle below 

 the hinder dorsal rays. J? to 52 scales in a longitudinal series, 5 or 6 between first dorsal 

 spine and lateral line, 4 between middle dorsal sjjines and lateral line. Dorsal X 15-17. 

 Anal in 7. 



I. Dorsal spines subequal from the third or fourth, the third not produced. 



A. Length of head 3 to .3^ in the length of the fish. 



Maxillary extending to below middle of eye (adult) ; fourth dorsal spine 5 



the length of head ; 44 to 46 scales in the lateral line A. hijpselosoma, Blkr. 



Maxillary extending to below posterior part or posterior edge of eye (adult) ; 

 fourth dorsal spine ?. (adult) or 5 (young) the length of head ; 47 to 49 

 scales in the lateral line A. cooperi, Regan. 



B. Length of head 3^ in the length of the fish ; fourth dorsal spine ? 



the length of head (young) ^1. tosniatus, Klunz. 



II. Third dorsal spine produced into a short filament A. pleurotcenia, ^Ikr. 



XENANTHIAS, gen. nov. 



Body compressed ; scales large, smooth, ciliated. Lateral line incomplete, ending 

 below the soft dorsal ; tube straight, extending nearly the whole length of the exposed 

 part of the scale. Mouth rather large, protractile ; no siipramaxillary ; jaws with 

 villiform teeth and a few small canines ; narrow^ bands of teeth on vomer and palatines ; 

 tongue smooth ; head scaly, except snout, lower jaw, and lower part of maxillary ; 

 prceopercle, subopercle, and interopercle serrated ; three opercular spines. Gill- 

 membraues separate; 6 or 7 branchiostegals ; pseud obranchise present; 3| gills. Two 

 dorsals connected at the base with X, 14-1.5 rays, the spinous dorsal a little longer than 

 the soft. Anal short, with III 6-7 rays. Caudal probably subtruncate. Pectoral 

 subsymmetrical, pointed ; rays 14, all simple, not branched. Ventrals below pectorals, 

 close together, with I 5 rays. 



Evidently closely allied to Bactijlanthias, Blkr., which lias the dorsal fin undivided, 

 From Bleeker's figure of D. liaplodactijlus it would ajjpear that the lateral line may be 

 only vestigial on the caudal peduncle in that species, 



41, Xenanthias gardineri, sp. n. (Plate 28. fig. 1.) 



Depth of body 2f to 2| in the length, length of head 2| to 2§. Snout a little shorter 

 than eye, the diameter of which is 3J to 3| in the length of head and twice the inter- 

 orbital width. Lower jaw slightly projecting; maxillary extending beyond the vertical
