Among eelgrass and algae along shore and swim- 

 ming freely at the surface; taken in a dredge 

 lowered to 25 fathoms, though probably caught 

 on the way up. Smith. This writer gives 

 records for its local occurrence during winter, 

 spring, and summer. 



Recorded from stomachs of summer flounder,

 Sound; surface to 18 fathoms; sometimes 

 abundant, hidden within a dead shell of 

 Spisula or other bivalve. Smith. Vineyard 

 Haven and eastern end of Vineyard Sound* 

 (identified by M. J. Rathbun.) 



All the specimens examined by Smith were 

 taken in August and September and a large 

 proportion of these were females carrying eggs 

 and young. 



Michtheimysis stenolepis (Smith).

stenolepis, sp. nov.); S. I. Smith, 1879, p. 103

 Vineyard Sound, Buzzards Bay, Woods Hole, 



"shallow bays and coves about Vineyard 



Sound;" abundant locally among eelgrass; also 



dredged in a few fathoms among algae; recorded 



for January, April, May, July, September, and 



December. Smith . 

 " Ovigerous sacs" filled with eggs and young in 



December, January, and April. Smith. 



Schizopoda undetermined. 



Fish Hawk stations: 7572 (i), 7583 (i), 7718. 

 Phalarope stations: 3, 83. 



Great numbers of schizopods, doubtless representing several species, have for many years past 

 been taken by Mr. Edwards in the tow at the local pier. It has thus far been impossible to find 

 anyone willing to identify these. 



Order DECAPODA.a
