Panopeus is a larg-e genus with many species closely resembling 

 each other, and three of them are found within the city limits. 

 They are all small and have similar habits, being, as their name 

 indicates, mud-inhabiting forms. In muddy localities they are 

 found in considerable numbers, under stones below high water mark, 

 and extend from there out into deeper water. They are very com- 

 mon on the oyster beds, and many are brought up by the tongers
