The venti-ivl ray is bifurcated in its terminal half. The two 

 branches lie close together. The anteiior branch is thinner than 

 the posterior. 



The three lateral lays have a common origin. The j^osjtero- 

 lateral ray branches before the other two i-aj^s. All three r;xys 

 lie close to each other throughout their entire course. Their 

 terminal third is folded inside the bursa. 



Tlie externo-dorsal ray is slender, and pursues a curved course. 

 It does not reach the edge of the bursa, but ends by a, jxipilla on 

 the external surface. 



The dorsal ray is unique in virtue of its enormous length. It 

 measures 1"67 mm., and divides high up within "15 mm. of 

 its origin. After a short coui-se each primary division gives off

a long and a short branch lying close to each other. The 

 longer branch is '12 mm. and. the shorter -05 mm. in length. 

 These branches appear as oflshoots from the main stem, which 

 continues a straight course, parallel and close to the corre- 

 sponding ray of the other brnnch. Both end in a sharp point. 



Genital cone. — The cloacal opening is placed near the apex of 

 an elongated genital cone. The cone projects fiom the roof 

 of the bursa between the pre-bursal papilte. It is placed 

 ventrally and caudally, and is 'IS mm. in length and '04 miri. in 

 breadth. The cloaca! canal traverses its centre. Its opening 

 is overlapped by its projecting anterior lip, which forms the 

 apex of the cone.
