The form, outline, and articulation of the dorsal rays and 

 the interneural spine, as well as the same characters of the anal 

 rays and interhsemal spines, are shown in text fig. 5. 



The interneural spines (44) of the anterior abdominal region 

 are illustrated in Plate I, and in Plate XIV they are disarticulated. 

 Dorsal ray (45). In Plates I and XIV this number indicates 

 the 8th dorsal ray, shown from the left side. 



Dorsal ray (116). This is the second, and is seen in Plates 

 I and XIV. 



The 6th ray of the dorsal fin (121) is indicated in Plates I 

 and XIV. In the latter plate it is exposed from the posterior 



side, while in Plate I it is 

 still articulated and is in 

 the natural position. 



The interhsemal spine 

 (57) is in the posterior 

 abdominal region. The first 

 spine in this series is 

 almost straight, with a 

 condyle at its ventral ex- 

 tremity to articulate with 

 the anal ray. In the others 

 there is an anterior vertical 

 fossa, while the posterior 

 portion is lamellar. No. 

 117. This is illustrated 

 in Plates I and XIV. In- 

 terhasmal spines (117). 

 The 19th and 20th spines are indicated by this number in Plates 

 I and XIV, being situated in the posterior abdominal region. 



Rays of the anal fin (58). This number in Plates I and XIV 

 represents one of the anal rays from the posterior side, showing 

 the two lateral portions and the cartilaginous nodule between 

 their distal ends. 



Interneural spines (82) . The spines indicated by this number, 

 82, in Plates I and XIV are in the posterior abdominal region. 

 In Plate XIV the dorsal rays in this region are not represented, 

 but they are present in Plate I. 



Anal ray (118). The 3d anal ray in Plates I and XIV bears 

 this number. 



The 24th anal ray is labeled 119 in Plates I and XIV. 

 Anal rays 4 to 11 are indicated by number 120 in Plates 

 I and XIV. Those in Plate XIV are viewed from the posterior

 interhaemal spine, and cartilaginous nodules. The 

 nodules are seen between the rays and spine.
