*Referenceis made in the present paper (pp. 30, el seq. and figs. 15 b-f) to several "species" of capsules 

 of Callorhvnchus; c. g., Specimen 79S3, Zool. Mus. Jardin des Plantes, Cape of Good Hope (Quoy and 

 Gaimard); Specimen 79S2, Zool. Mus. Jardin des Plantes, Cape of Good Hope (Voyage Peron); 

 Specimen 7g84, Zool. Mus. Jardin des Plantes, Chile (Martinez) ; Specimen 8823 a, Zool. Mus. Jardin des 

 Plantes, Straits of Magellan (Savatier). Also to specimens from Australia in the British Museum.

The fossils Spirangium, Paljeoxyris, Fayolia, and similar forms may prove to be the egg- 

 capsules of Chima-roids or of cestraciont sharks. From their imperfect preservation, 

 however, they may equally well be coprolites of fishes having spiral intestinal valves. To 

 a somewhat more definite category, however, belongs the following "Spirangium" ;

Cf. fig. 13. If this prove to be aChimsroid egg-capsule it is remarkable in a feature suggest- 

 ing the capsule of a cestraciont — marginal webs arranged in spiral.
