Explanation of Plate XXIV. 



Figs. 1-5. Appendages of Ceplmiodcs hylas, L. (India). 



Fig. 1. Seen from left side, x 8 diam. Shows relative size and form 

 of left and of ri^ht clasps. 

 ,, 2. Same from right side showing right clasp, x 8 diam._ 

 ,, 3. Extremity of ledosagtts showing spine beyond opening, x 

 140 diam. 

 4, 5. Lateral and dorsal views of tegumen to show twist, x 9 

 diams. 

 ,, 6. Left clasp of CepJi. hylas 1 (Africa?) showing somewhat 

 different form, x 12 diam. 

 Torn end at separation shows want of definite articulation. 

 ,, 7. Left clasp of C'ejjh. kingii, Macl., from within, x 7 diam. 

 ,, 8. Ri£;ht 



„ 9. ^^\limgus oi „ ,, ,, ,, x .36 diam. 



The g&docagus is shorter, more robust, and with the opening 

 much further from the extremity than in Ceph. hylas, 07 

 m.ni. instead of OB. In this, in the form of clasps, and 

 in the trifling, if any, asymmetry in the tegumen, Ceph. 

 kingii is much nearer to Hciimris than it is to Ceph. hylas.

Fig. 10. Shows hook which passes across dorsum to left side. The 

 figure accurately follows preparation pressed on glass slide, 

 in which the hook has been forced from its somewhat 

 close apposition to the margin of the tube, x 15. 

 11. The same to show eversible membrane extended with its two 

 apparently asymmetrical chitinous filaments attached, 

 X 12. This figure is rather from above, than a lateral 

 view. Fig. 10 rather from below, but both are from 

 flattened specimens.
