Subfainily 2. FERWPHTiiALirryjE. 



Eyes close together, prominent, erectile ; base of pectoral 

 fin very muscular. Pectoral radials elongate, inserted on a 

 broad laminar ridge ot" tlie cleitlirum ; hypocoracoid and 

 cleitluum enclosing a large foramen. Vertebrae 25 or 26 

 (10-11 + 14-16). 



Periopldltalnuis, Boleophthahnus. 



Family 3. Psammichthyidae. 



Tlie little fisii from the Seychelles which I named 

 Psiiinmichllitjs nudus "^ and placed in the family Trichonotidte 

 agrees better with the Gobioids in tin-structure and in the 

 number of vertebrje, and may provisionally be referred to 

 this suborder. The body is elongate, naked; the eyes are 

 very small and close together ; the mouth is oblique, with 

 the lower jaw prominent, pointed, and with narrow bands of 

 teeth in the jaws; the gill-openings are wide, but tlie gill- 

 membranes are narrowly joined to the isthmus. The 

 vertebra?, judging by the myotomes, number 24 or 25. The 

 dorsal fin is single, of 19 rays, the tirst live spinous, the last 

 spine rather distant from the fourth and from the first soft 

 ray ; the anal has 1-4 rays, the first a feeble spine, the caudal 

 11 principal rays (9 branched), the pectoral 8 rays. The 

 pelvic fins are separate, close together, a little in advance of 

 the pectorals, each of a spine and 5 soft rays.
