The Schizopoda collected by the Maia and Puritan in the Mediterranean. 119 
Ali but 5 Speeles on this list: Euphausia gibba^ Nyctlphanes 
norvegica^ Eucopia australis, Euchaetomem tennis^ Boreomysis arc- 
tica, must in my opinion be deleted from the Mediterranean list in 
accordance with the suggestions given above. 
Holt & Tattersall (1906) from specimens from this coUection 
kindly forwarded at the time by Dr. Lo Bianco were able to add 
Nyctiphanes coucìiii and Pseudomma ealloplura to the Mediterranean 
fauna, while the foUowing 11 species are now recorded from the 
Mediterranean for the first time: 
Euphausia brevis. 
Thysanopoda aequalis. 
Thysamessa sp.? 
Parerythrops lobiancoi. 
Euchaetomeropsis inerolepis. 
Paramblyops rostrata. 
Pseudomma kruppi. 
Calyptomma puritani. 
Mysidetes farrani. 
Siriella norvegica'? 
Mysidella typica. 
This list, together with the alterations suggested above, gives 
a total of 17 species out of 30 contained in the material, which the 
Maia and Puritan first made known from the Mediterranean. When 
we consider the small area explored by these boats and the com- 
paratively few hauls taken actually on the bottom, it would seeni 
that there is much remaining to be done in the elucidation of the 
Mediterranean fauna. 
An examination of the list of species bere recorded, shows, as 
might bave been expected, that there is a considerable resemblance 
between the pelagic fauna of the Mediterranean and that of the 
Eastern Atlantic. Ali the pelagic Euphausians noted below as well 
as Eucopia unguiculata and Euchaetomera tennis among the pelagic 
Mysidaceans are widely distributed in the Eastern part of the Atlantic 
Ocean from the waters off the British Islands as far south as the 
Azores. Of the remaining two pelagic forms, Arachnomysis leuckarti 
is at present only known from the Mediterranean, while Euchae- 
tomeropsis merolepis has so far only been found in the Indian ocean, 
outside that sea.
