dorsal (PI. xxxi, Fig. 3, cr. sc). These appear to consist of 

 squarish masses whose broad sides are applied to the similar 

 masses in front and behind, while the narrower sides look 

 outward and upward. There seem to be about three or four 

 of such masses for each median scale. 



All the specimens are from Hajula. The species is named 

 in honor of Professor Alfred Ely Day, of the Protestant 

 Syrian College at Beirut, who made the collection which is 

 described in this paper. 



Rhinellus delicatus, sp. nov. 



The type of this species is a small and probably young fish. 

 Its number is 4530 (3661). The total length is only 32 mm.; 

 from the snout to the base of the caudal fin is 26 mm. It is 

 also quite slender, the greatest depth being only 2.5 mm. 

 The head is injured, so that little except the upper and lower 

 jaws remains. The whole head seems to have been 7 mm. 

 long. The jaws are slender and are 4 mm. long, but it is not 

 certain that the extremities are not broken off. No teeth are 

 to be seen. Pectoral, ventral, dorsal, anal, and caudal fins 

 are all present. The pectorals have a length of 4 mm. The 

 ventrals are inserted 4.8 mm. behind the base of the pectorals. 

 The number of the rays cannot be determined. The origin of 

 the dorsal fin is about 2 mm. behind that of the ventrals. The 

 rays are delicate, and those that can be counted are 8 in 

 number, but these probably do not represent the whole num- 

 ber originally present. The anal fin is placed halfway be- 

 tween the dorsal and the caudal fins. The number of its rays 

 cannot be determined. The caudal fin is deeply forked. 



There appear to be 43 vertebrae. These, especiahy the 

 more anterior ones, are somewhat longer than deep. No ribs 

 are seen. Scales are present, but their boundaries are indis- 

 tinguishable. 



This fish differs from others of the genus in having the 

 origin of the dorsal fin much nearer the occiput than to the 

 base of the caudal fin. 



This species comes to us from Hajula.
