posed in longitudinal lines ; sides of the snout, pectorals and ventrals in 

 some tinged with carmine ; beneath whitish. Iris golden ; pupil trans- 

 versely oval, black. (Bloch-Schneider. — Russell, X. — Far. 2, Miiller 

 und Henle.) 



Far. 3. Muller und Henle. — With numerous round spots on the 

 snout, head, back, tail and pectorals. (Rhinobatus djeddensis, Riippell.) 



(Adult.) Either uniformly coloured, or with indistinct spots ; but 

 without spots at the point of the snout, and without bands on the 

 upper eyelid. 



Habit. — Sea ofPinang, Malayan Peninsula, Singapore, 

 Indian Ocean, Bay of Bengal, Red Sea. 



Total length : 5 feet. 



Spiracles with two denticulations at the posterior margin. The 

 length of the snout is a little less than T of the total. The distance of 

 the nostril from the lateral margin is \ of the length of the nostril. 

 The distance between the anterior extremities of the nostrils is double 

 the length of each nostril ; the distance between the posterior extre- 

 mities is a little less than the length of each nostril. The anterior 

 dorsal commences a little behind the commencement of the ventrals, 

 and extends a little farther back than the latter. The extent of the 

 base is less than one half of the anterior margin. The posterior dorsal 

 is smaller ; its distance from the caudal is a little more than one half of 

 the distance from the anterior dorsal. Both dorsals are similar, ter- 

 minating in an attenuated point, but the posterior is much the smaller. 

 The extent of their base is less than one half of their anterior margin. 

 The pectorals appear triangular. The ventrals terminate in an attenu- 

 ated point, which extends to the opposite point of the anterior dorsal. 

 The posterior margin of the caudal is very concave ; the lower lobe 

 but little smaller than the upper. The lateral keel commences a little 

 above the termination of the ventrals. The scales are very minute 

 subrhomboidal or orbicular and imbricated ; they carry from 3 to 6 

 keels. A number of small recurvous spines are at intervals distributed 

 J n lines. One such, the supraorbital, surrounds the anterior part of 

 the orbit, and extends backwards to above the spiracle. Another, the 

 dorsal, extends along the spine to the posterior dorsal. As in Rhina 

 ancylostomuSy there appear two conspicuous pores a little in front of 

 the dorsal line. In young individuals these pores are less distinct. A
