* As the filamentous end of the capsules is usually defective the measurement of length includes only as far as 

 the base of the filament. This length can be estimated with fair accuracy and serves as a convenient basis ( 100 per 

 cent) of proportions. It is understood that the present estimates are approximate, but they are probably not far from 

 the mean of the species. 



f This specimen could not be identified at the Jardin des Plantes. According to Dumeril's description it is 

 smaller than the specimens there preserved, measuring but 21 cm. in length (not counting terminal filament). It has 

 also hook-like processes at the tips and sides of opercular valve. Locality unknown.
