Col. Tickell figured two varieties of a species of this genus taken at Saddle Island, off 

 Kyouk Phoo. He gave the D. 22, A. 13-14, and stated that the scales -were large. The 

 one he termed Malacocantlms coccinicauda being of dark burnt umber colour, becoming a 

 little purplish below. Pins pale brown. Dorsal rays vermilion. Anal with a pale red 

 band along its centre. Caudal deep carmine. The second, M. hicolor, had the anterior half 

 of its body yellow olive-green, its posterior half superiorly including eyes, dorsal, caudal, 

 and anal fins sepia, upper and lower margins and angle of caudal whitish gray. Pectoral 

 and ventral yellowish. A row of small irregular spots of a smalt colour along the middle 

 of the posterior half of the body. 



Page 278. Add Genus 2— Trigla, Artedi. 

 Hoplonotus, Guichenot. 



BrancMostegals seven : pseudohrancMce present. Head parallelopiped, with its superior and 

 lateral surfaces bony. Villiform teeth in both jaws, and usually on the vomer, btit none on the 

 palatines. Tivo dorsal fins, the first being of less extent than the second: three free filaments 

 at the base of the pectoral fin. Air-hladderivell developed, generally provided with lateral 

 muscles, and sometimes partially divided internally by partitions. Pyloric appendages few or 

 in moderate numbers. 



Geographical distribution.— Coa,sts of Europe, and one species extending across the North 

 Atlantic to the western shores of North America. To the south it passes round the west 

 coast of Africa from the Atlantic to the Indian Ocean, and one species has been obtained 

 in the Persian Gulf on one hand, and also in Japan ; consequently it is here inserted as 

 Indian.

Length of head about 3, of caudal fin 5|, height of body 5| in the total length. Eyes— 

 li diameters from the end of the snout, and 1} apart. Profile from upper edge of orbit to 

 the snout scarcely concave. Preorbital produced anteriorly into a flattened spine ; two 

 spines on the preopercle, the upper the larger. Opercle ending posteriorly in a strong 

 spine equalling the diameter of the orbit ; shoulder bone with two spines. Teeth— 

 villiform. Fins — dorsal spines strong, the third and fourth the longest. A bony plate along 

 the base of the dorsal fin, wider in small than in large examples. Pectoral reaches to above 

 the third anal ray, three free appendages. ,S'ca/es— small. Colours — upper part of body 

 rosy, witli numerous small rounded or oblong black spots : lower half of body white. 

 First dorsal with a large black oblong blotch and a row of small round black dots along 

 the middle of the second dorsal: inter-radial membrane of pectoral bluish-black. 



Habitat. — An example 9 inches long has been obtained from Muscat, the species has like- 

 wise been brought from Japan. 



Page 278. Genus 3 — Peeistethus, Kaup. 



Brancliiostegals seven : pseiidobranchim present. Bead parallelopiped in shape, the sides 

 and upper surface cuirassed with bone : the preorbital prolonged aideriorly into a flat 

 projecting 2n-ocess. One or more barbels on the lower jaw. Teeth absent. One or two dorsal 

 fins, the posterior of which is most developed. Tivo free pectoral appendages. Body covered 

 ivith bony, scale-like plates. Pyloric appendages feiv, or in moderate numbers. Air-bladder 

 present. 



Geographical distribution.— Vrom the south coast of Britain to the Mediterranean, also 

 from the Atlantic and Indian Oceans to China. It has likewise been obtained at the Sand-
