MORPHOLOGY OF CYPRINODONT FISHES. ZO 



structures developed in the intermuscular septum, and I feel 

 this opinion strengthened as the result of my work on the

Skeletons of Fhallostetlius dunckeri (A) and Neostethits lankesteri (B), 

 reconstructed ; A 6 and B 5 times the actual size.

Neostethus lankesteri. 



A. Transverse section tlirougli anterior part of seminal papilla and adjacent portion 



of glandular groove (X 130). e., glandular epidermis lining folds and 

 pockets on surface of papilla; p., papillary' bone; sp., mass of mucus con- 

 taining spermatophores, Ij'ing in the vas deferens, where this opens into the 

 glandular groove {g.) ; a., process of axial bone. 



B. Transverse section through glandular groove and pulvinulus at base of pul- 



vinular appendage (X 130j. g., glandular groove; i., infrapulvinular groove; 

 is., anterior infrasulcar bone ; pvb., cartilaginous terminal process of inner 

 pulvinular bone, for articulation of pulvinular appendage {pva.).
