vi. a review of the fishes of the family mu- 

 gilid.f: found in the waters of Formosa. 



By Masamitsu Oshima, Ph.D. 



(PlS. XI. XII, AND XIII, FIG. I.) 



The present paper gives an account of the species of fishes belong- 

 ing to the family Miigilidcc found in the waters of the Island of 

 Formosa. It is based on the collections of the author, preserved in 

 the Museum of the Institute of Science of the Government of For- 

 mosa, a series also being sent to the Carnegie Museum, including the 

 types of the new species. Of the ten species the four following seem 

 to be new to science: 



I. Mugil anpincnsis, 2. Liza formoscc, 



3. Liza pescadorensis, 4. Liza parva. 



I am indebted to Dr. David Starr Jordan for help in the preparation 

 of this paper. 



Family MUGILID.F:. 



(The Mullets.) 



Body oblong, more or less compressed, covered with rather large 

 cycloid scales; no lateral line, but the furrows often deepened on the 

 middle of each scale, so as to form lateral streaks ; mouth small, the 

 jaws with small teeth, or none; the teeth, if present, mostly loosely 

 attached, often ciliiform; premaxillaries protractile; gill-openings 

 wide, the membranes separate, free from the isthmus; branchiostegals 

 five or six, gill-rakers long and slender; gills four, a slit behind the 

 fourth ; pseudobranchiae large ; two short dorsal fins, well separated, 

 the anterior with four stiff spines, the last one of which is much 

 shorter than the others; second dorsal longer than the first, similar 

 to anal; anal spines usually three (two in the genus Querimana) 

 graduated ; ventral fin abdominal, not far back, composed of a stiff 

 spine and five rays; caudal forked; air-bladder large, simple; intestinal 

 canal long; peritoneum usually black; vertebrae twenty-four. Genera 

 about ten, species about one hundred, inhabiting fresh waters and 

 coasts of warm regions, feeding on organic matters contained in mud.
