Apel (61) and Scharff (64) have contributed to our knowledge of the 
anatomy of Priapulns and Halicryptus ; the course of the peripheral 
nerve-fibres is especially described. 
The new genus Golfingia (63) is allied to Aspidosiphon , but differs in 
the possession of a “ scleropyge ” and a “ sclerorhynchus,” in the arrange¬ 
ment of the retractors, and the character of the oral tentacles. G. macin- 
toshi, sp. n., off the E. coast of Scotland. 
Caldwell (62) makes the development of Phoronis the text for some 
general morphological considerations.
