The Scliizopoda collected by the Maia and Purltan in the Mediterranean. 141 
slenderDess of the thoracic legs separates the present examples from 
S. jalteìisis and there remains only 8. norvegica io which they can 
be referred. In other respects they agree equally well with adult 
8. clausii or young 8. norvegica^ two species extremely closely allied. 
If the character of the apical spines of the telson can be relied 
on, there can be no doubt that the specimens belong to 8. norvegica 
but it is not beyond the bounds of possibility that extended Obser- 
vation would show this character to be variable enough to allow of 
the merging of the two species under one name, 8. norvegica. 
It should be mentioned bere that Dr. Lo Bianco himself seems 
to bave been in doubt as to whether these specimens should be 
referred to 8. norvegica or 8. clausii^ since the bottle in which they 
reached me contained two labels with the former name on one of 
them and the latter on the other. 
8. norvegica does not appear to bave previously been recorded 
from the Mediterranean proper though Norman (1892) records a 
specimen from off Gibraltar at the entrance to the Mediterranean. 
27. Saplostylus normani (G. 0. Sars). 
Gastrosaccus normani^ Lo Bianco (1901, 1903). 
The specimens agree with Sars' originai description of the 
species in being without lobes on the hinder margin of the carapace. 
The species is common in the Mediterranean. 
28. Anchialina agilis (G. 0. Sars). 
Anchialus agilis^ Lo Bianco (1903). 
Norman has recently (1906) substituted the name Anchialina for 
Anchialus Kröyer, which was preoccupied for a genus of Coleoptera. 
The species is widely distributed in the Mediterranean. 
29. Boreomysis arctica (Kröyer). 
B. arctica^ Lo Bianco (1903). 
No difference could be noted between the Mediterranean spe- 
cimens and those from the west coast of Ireland, with which they 
were compared. Dr. Lo Bianco has given some iuteresting notes 
on the Variation in colour of these examples. 
The depths at the stations at which it was captured varied 
between 950 metres (520 fathoms) and 1900 metres (1040 fathoms). 
AH the specimens were caught on the bottom with the exception
