ZOOLOGY OF THE BERMUDAS (continued). 



MOLLUSCA. 



The species of mollusks enumerated in the following pages, 

 although probably far short of the actual number found in 

 the region, give a good idea of the character of the mollus- 

 can fauna of the archipelago. Somewhat more than 170 

 marine forms, and 30 terrestrial species, are catalogued ; before 

 our visit barely more than one-half of this number had been 

 officially recorded from the Bermudas. The general relation- 

 ship of this fauna has already been discussed in Chapter V, 

 and it is, therefore, not necessary to enter here into any further 

 details connected with the subject. 



CEPHALOPODA. 



Cuttle fishes are said to be abundant in the Bermudian 

 waters, but we were not very successful in our search after 

 these animals. Two moderately large octopods, which we 

 could only see, but not obtain, may possibly be the common 

 West Indian Octopus vulgaris, or one of the forms that have 

 been separated off from it as a distinct species. We made 

 considerable efforts to capture one of these, but all our at- 

 tempts to dislodge the creature from its hold upon the interior 

 of a rock-crevice were unvailing. The following species 

 (Octopus chromatus) was obtained beneath a stone on the beach 

 of Flatts Village,
