Order MYSIDACEA 



The order Mysidacea falls naturally into two clearly distinct groups which differ so profoundly from one 

 another that they have been given the status of suborders under the names Lophogastrida and Mysida. 

 The Lophogastrida show the following primitive characters which are absent in nearly all the 

 Mysida: 



(1) Large foliaceous gills present on the thoracic appendages. 



(2) No statocyst on the endopod of the uropod. 



(3) Pleopods of both sexes biramous, multiarticulate, natatory and unmodified. 



(4) Marsupium composed of seven pairs of imbricating brood lamellae. 



(5) Well-developed pleural plates present on the abdominal somites. 



(6) A more or less well-marked transverse groove encircling the last abdominal somite and marking 

 the incomplete fusion of the sixth and seventh abdominal somites of the embryo. A pair of lateral 

 teeth immediately in front of this groove marks the postero-ventral angle of the sixth abdominal 

 somite of the fossil forms and of the embryo.
