FAMILY, I— PERCHLE. 101 



commencement as it is long. Colours — silvery, with a dark margin to the dorsal and anal fins, and a spot on 

 each spine and ray of the dorsal fin about its middle. 



Habitat. — Seas of India. The type specimen at Paris is 4f inches in length, and from it the above 

 description has been taken. I obtained a specimen 5 inches in length at Madras. It much resembles G. litcidus 

 but is destitute of the dark blotch on the dorsal fin. 



Genus, 30 — Pentaprion, Bleeker. 



Clafa, Gill. 



This Genus differs from Gerres in having the inferior pharyngeal tones separate: 14 to 15 rays in the dorsal 

 fin : 5 anal spines, and 13 or 14 rays.

Length of head 4J, of caudal 4J, height of body 3f in the total length. Eyes — diameter 2| in the 

 length of head, 2/3 of a diameter from end of snout, and 1 apart. Body of a long oval shape : dorsal and anal 

 profiles equally convex. Snout slightly swollen. The posterior process of the premaxillary reaches to opposite the 

 first third of the eye. No spines or serrations around the orbit. The maxilla reaches to below the front edge 

 of the eye. Mandible not concave inferiorly. Lower preopercular edge serrated. Teeth — villiform in the jaws, 

 vomer and palate edentulous. Fins — dorsal spines weak, the first very short, the second one-third the height of 

 the third which equals 4/7 of the length of the head. Pectoral equals the height of the body. Ventral reaches 

 two-thirds of the distance to the anal. Second anal spine the longest and equal to 1/3 of the height of the body : 

 caudal forked, upper lobe the longer. Free portion of tail rather higher than it is long. Scales very deciduous, 

 they extend forwards over the back to opposite the middle of the eyes. Colours — silvery, with a silvery stripe 

 from the eye to the base of the caudal fin. 



Cantor erroneously gave 4 spines instead of 5 to the anal fin, in this he appears to have been copied by 

 Dr. Giinther. The specimen is much mutilated but 5 spines are still visible. 



On mentioning this fish to Dr. Bleeker he at once showed me his types of Pentaprion gerroides, 

 which are identical. 



Habitat. — Madras, where I procured several specimens, to the Malay Archipelago. Cantor observes that 

 "in the Straits of Malacca this species is very abundant at all seasons, and quantities, both fresh and dried, are 

 consumed by the natives." 



ADDENDA AND CORRIGENDA. 



Page 18. Serranus lanceolatus. 



After this portion of my work had been printed I went over to Leyden to examine the types of S. Jwrridus 

 and S. geographicus. 8. horridus (K. and v. H.) Cuv. and Val. ii, p. 321 is 9^ inches in length ; S. geographicus 

 (K. and v. H.) Cuv. and Val. ii, p. 322 is much larger; both are stuffed, painted and varnished, and I consider 

 are forms of S. lanceolatus, Bloch, and not of S. fuscoguttatus, under which they are placed at p. 22.

Having seen Valenciennes types I have no doubt but that they represent this species as stated by 

 Klunzinger. One specimen still shows traces of longitudinal bands.

This fish is identical with A. Bankanensis, Bleeker, whose name has the priority. Dr. Bleeker showed 

 me specimens of his fish with the markings as well seen as in Dr. Giinther's specimen and figure. The follow- 

 ing references have to be added : —
