Schwarz, E. H. L. — The descent of the Octopoda. Journ. Mar. Zool., 1894, 

 vol. i., pp. 87-92. 



The author proposes " the division of the Cephalopoda into the Endocochlia 

 and the Ectocochlia ; the first including the Belemnitidce, Sepiadic, Teuthida, and 

 Spiralidic, while the second includes the Nautiloidea, Ammonoidea, and the 

 Octopoda." [The names are not very convenient as Entoconcha and Ectoconcha 

 have already been used in divisions of the Opisthobranchiata.\

This paper and ensuing discussion contains much to interest Conchologists, 

 though likely from its position to escape their notice. In the warm waters of the 

 Gulf of Mexico the growth of 7eredo is observed to be more rapid than in 

 the Eastern States or North Europe. Three months' exposure suffices there 

 to riddle an 18 in. pile. The creosote with which piles are saturated was found 

 to be washed out in time. As the best protection for piles a concrete shell 

 is recommended.
