Of the 13 bottoni haunting forms in this material, no fewer than 
10 are found in the seas to the west of the British Isles, 7 of them 
extending as far north as Norway. 
Special interest attaches to the records of Pseudomma calloplura^ 
Paramblyops rostrata and Mysidetes farrani, since these species have 
only been recently described, from specimens captured off the West 
Coast of Ireland. The 3 species which are peculiar to the Medi- 
terranean, are the new ones, Parerythrops lohiancoi replacing the 
northern P. obesa ^ Pseudomma kruppi a species very closely allied 
to some of the northern members of that genus and Calyptomma 
puritani^ a species with no very near relative among described 
forms. I append two tables showing the distribution of the various 
species in the several hauls of the Maia and Puritan, followed by 
a table showing the known distribution of the species in the seas 
of the globe. 
The term "first thoracic limb" in the following notes is applied 
to the appendage formerly known as the maxillipedes and the 
remaining thoracic appendages are noted by their corresponding 
numbers only.
