Neatypus, gen. nov. 

 Family Scorpidid^e. 



Head and body compressed, completely scaled. Scales moderate, 

 finely ciliated and irregularly arranged ; lateral line complete. 

 Mouth small, transverse, slightly protractile. Maxillary small ; a 

 broad band of trilobed movable teeth in each jaw : vomer and 

 palatines toothless. Gill membi'anes united, free from the 

 isthmus. Seven branchiostegals. Gill-rakei-s long. A single 

 dorsal with ten spines and about twenty-two rays, the spinous 

 portion well developed but shorter than the soft ; anal with three 

 spines, the second long and sti'ong, and about eighteen rays. 

 The bases of the spinous portion and the whole of the soft 

 portion of both fins, densely covered with small scales. 

 Caudal scaled like the vei'tical fins. Pectoral with fifteen rays, 

 the upper of which are longest, the tip rounded. Ventrals 

 inserted close togethei', behind the base of the pectorals, spine 

 strong. 



The genus is allied to Atypichthys, Giinther", difftning by the 

 character of the teeth and the scaly base of the spinous portion 

 of the vertical fins. The greater vertical development of these 

 fins at once distinguishes it from Scorpis, and possibly also from 

 Farascorpis. The small mouth prevents any confusion with 

 Atypoiioma, and the general habit with other two genera included 

 by Dr. Boulenger**, Psetttis and Henoplosus ( Enoplosns). 



It has much the habit of Chmtodon, but differs therefrom by 

 the nature of the teeth and by the gill membranes l>eing free 

 from the isthmus. Of this last character Boulenger writes under 

 Chcetodoiitido'^ : — " Closely allied to and evidently derived from
