Candacia armata, Boeck (No. 13).—This species was observed 
for the first time early in February, when a single specimen was 
obtained, and it did not occur again till September, but after that 
it was noticed at odd times till near the end of the year. As 
stated by the late I. C. Thompson, in his remarks on the Copepoda 
of Valencia Harbour,* this species, though widely distributed, is 
‘‘generally rare in our seas,” and appears to some extent to be. 
affected by seasonal] influences. 
Labidocera Wollastont (No. 14) is a moderately rare species in 
the Clyde. It was represented in the collection by only two 
specimens, which occurred in a gathering collected at the end of 
~ October. i : 
Anomalocera Patersoni (No. 15).—This species is widely, but 
at times not very regularly, distributed. Sometimes it occurs 
sparingly, and at other times it may be the most common form in 
the gathering. In the present collection there was no trace of it 
till September, and from that time onwards no more specimens 
were noticed. 
Parapontella brevicornis (No. 16).—This species occurred very 
sparingly towards the end of April, and again in September, October, 
and November. | 
Cyclopina littoralis and C. gracilis (19 and 20).—These two 
species are demersal in their habits, and therefore, though frequent 
in gatherings made with the dredge, they are only occasionally 
taken with the tow-net. 
Longipedia Scotti and L. minor (21 and 22) are also demersal 
forms of frequent occurrence, especially the former (21). Till 
recently, this species has been recorded under the name of 
Longipedia coronata, Claus; but Prof. G. O. Sars has shown that 
this common British form is not the species described by Dr Claus, 
and he has therefore renamed it as above.t ic 
Microsetella norvegica (No. 23) [Microsetella (or Eetinosoma) 
atlantica, Brady and Robertson]. This minute species was obtained 
in a sample collected about the end of January, and this was the
