eyes than 5. obtusata. In the number of scales in the lateral line it approaches 

 Sphyraena sphyraena (L,.), more commonly known as Sphyraena vulgaris, which has 

 one hundred and fifty scales in the lateral line against one hundred and forty-four 

 in the new species ; the new species is a deeper fish than 5. sphyraena and possesses 

 larger eyes. From all the recently described species of the genus it differs consider- 

 ably. From 5. af ricana, Gilchrist, 1 it differs in the character of its teeth, in possessing 

 a smaller eye and a shorter maxillary, in having the pectoral fin not ending below the 

 origin of the spinous dorsal and not having the ventrals in advance of the origin of 

 the first dorsal, besides other differences. 5. ensis, Jordan and Gilbert, 2 has a longer 

 head, a less deep body, a larger eye and longer maxillary. 5. goodingi , Seale, 5 is 

 much less deep, possesses short gill-rakers (gill-rakers are absent in the new species) 

 and differs in the position of the fins. S. pelleri, Jenkins/ has longer eyes and is 

 much less deep than the new species and differs in the number of rows of scales on 

 the cheek. 5. putnamiae , Jordan and Seale, 5 differs in the length of the maxillary and 

 also in the character of the teeth, in the proportions of the fins and in colouration. 



The new species differs from 5. pinguis, Günther, in the character of the tip of 

 the lower jaw, in the position of the fins and in the number of scales in the lateral 

 line. 5. snodgrassi, Jenkins, 1 has a larger eye, longer maxillary and a smaller num- 

 ber of scales in the lateral line. 5. tome, Fowler, 8 differs in the depth of the body, 

 in the number of scales in the lateral and transverse lines, in the width of the head 

 and in the depth of the caudal peduncle, etc. 5. waitii? Ogilby, differs in every 

 particular except in the height of the body and the length of the head. 



The type-specimen was collected at Satpara in the outer channel of the lake. 

 The period of its capture is not noted. Evidently the species is an occasional visitor 

 to the part of the lake that is nearest to the sea. The type is 210 mm. in length 

 without the caudal fin and is entered in the register of the Zoological Survey of India 

 under No. F. 9453/1.
