Not uncommon in Chateau Bay, in thirty fathoms. Cateau Harbor, Lone Island fifteen 

 fathoms sand. Appearing different from Bate's figures and description of A Gaknark I had 

 described it as a new species, but refer to Mr. Beck's identification of my specimen.

Haploops tubicola Kboter. 



This is quite a different genus from the foregoing, as specimens received from Dr Liitken 

 show us. Our specimens agree well with some from Denmark 



Cateau Harbor, Long Island, ten miles above Domino Harbor, in fifteen fathoms, sand 

 dredged in company with the species of Ampelisca. 



Pontoporeia femorata " Kroyer, Nat. Tidsskr. iv. p. 153 ; Voyage en Scand. pi. 23, fig. 2."

Body robust ; antennae subequal in length ; superior pair with the first joint of the flaeel 

 lum one fourth shorter than the cephalon ; whole antenna extending to the third joint of 

 the thorax ; appendiculus minute. The first pair of gnathopoda have the propodos Wer 

 than the carpus, which is not produced beneath; inferior margin of propodos curved and 

 nearly parallel with the superior margin. Second pair of gnathopoda with the propodos 

 ovate, twice as long as wide, one third shorter than the carpus, and densely frino-ed Basos 

 of the last pair of thoracic legs large, orbicular, hinder edge entire, well rounded -last pair of 

 pleopoda longer than the others. Fourth abdominal segment with a high, erect' stout very 

 prominent spine, ending in two acute spinules. Length, .40 inch. Kroyer does not 

 figure the spine in the drawing reproduced by Bate; but specimens received from Dr 

 Lutken agree in all respects with ours. Belles Amours, Straits of Belle Isle, abundant in 

 five to eight fathoms, muddy bottom.
