the snout triangular, the next forming, over the eyes, two broad 

 bars separated by a narrow belt of ground colour, two others of the 

 same kind on the nape, then one rather narrower, a double one 

 again at the dorsal spine, extending on the pectoral fin, and so on, 

 broad double and single bands alternating to the middle of the tail ; 

 these bands in no case extend across the belly.

More than one specimen of this remarkable Ray was captured 

 by one of the authors of this paper (N". de Miklouho-Maclay) during 

 a visit to the Admiralty and Lub, or Hermit Islands, in the year 

 1879. To preserve a specimen of this fish was under the circum- 

 stances impossible, but drawings and copious notes were made on 

 the spot. A jaw was prepared, which however, was afterwards 

 unfortunately lost. 



The most remarkable feature in this fish, is undoubtedly the 

 prolongation of the cephalic fins into a triangular pointed depressed 

 snout, as represented in fig. 4. The following measurements were 

 taken from a male adult specimen. 

 From the tip of the snout to the extremity of the 



ventral fin ... ... ... ... ... ... 1130 mm. 



Length of tail from dorsal fin ... ... ... ... 640 „ 



Diameter of the disk ... ... ... ... ... 1430 ,, 



Longitudinal diameter of the Spiracle .. . ... ■ ... 50 „ 



Length of longer spine .. . ... ... -,. ... 140 ,, 



„ shorter „ ... ... ... ... ... 82 „ 



The colour of the upper surface is greenish-grey with white spots 

 of different sizes, irregularly distributed, the under surfaces dirty 

 white, getting darker on the pectoral fins. The snout is long and 

 triangularly pointed. The eyes small with a vertical oval pupil. 

 Spiracles very large. Two barbed spines on the tail, one side of 

 the longer one is flatter than the other, which is marked with 

 longitudinal furrows and ridges ; the shorter spine is rounder, both 

 are barbed alike. (Figs. 5, 5' and 6.) 



The nostrils are in a horizontal line with the eyes.
