168 Part ITI.—Sixteenth Annual Report 
named species, but there are several other records of Cumaceans under 
the more general names of Cumacea, Cuma, etc., which I shall now refer to. 
The records of Cumaceans under these general names are as follows :— 
In 1890 the first is for Station V. in March; in April there are records 
for Stations III., VIII., and IX., and for Station VIII. in December. 
In 1891 the records are—one for Station VIII. in February, for Station 
I. in March, for Station VIII. in April, and for Station III in 
November. In 1892 there is a record for Station VIII. in March, for 
Station IX. in May, for Stations V. and IX. in July, for Station VIII. 
in September, and for Station IX. in December. In 1893 there are 
four records of Cumacea—viz., two in June for Stations I. and V., one in 
August for Station V., and one in October for Station IX. The only 
records in 1894 are—one for Station V.in February, and another for 
Station [X. in the same month. There are five records in 1895, one for 
Station IV. in February, one for Stations IJJ., VIII, and IX. in 
February, and one for Station VIII. in December. 
There does not appear to be any feature of special interest in the 
distribution of the Cumacea as brought out by the published records, 
except that a few of the species are rare or new in the British seas. 
(d) Isopopa. 
The next group of organisms that fall to be noticed is the Isopoda. 
This group is represented in the tow-net lists by six species, the names of 
which are as follow :— 
Gnathia (1) maaillaris (M. Edw.). Idothea emarginata (Fabr.). 
Hurydice pulchra, Leach. »,  lmearis (Linn.). 
Idothea baltica (Pallas). Janira maculosa, Leach. 
With the exception of Jdothea baltica, these Isopods were all 
extremely rare in the tow-net gatherings under consideration, and the 
records for them are as under :— 
Gnathia (1) maxillaris is recorded once in 1890, for Station VIII. in 
March. 
Eurydice pulchra is recorded in the same year for Station III. in 
November. 
Idothea baltica is recorded in 1889 for Station VIII. in February, and 
for Station IX. in January. In 1890 the same species is recorded in 
April for Stations IV. and V., and again for Station V. in October. In 
1891 it is recorded for Station I. in January and April, and for Station 
IV. in March. It is recorded again for Station IV. in May 1892. In 
1893 it is recorded in February for Station III., and in November for 
Stations I. and IV. In 1894 there is one record—viz., for Station LV. in 
April. In 1895 this Isopod is recorded in April for Stations L., IIL. IV., 
V., and VIIL, and for Station V. in September. It will be seen that nine 
out of the nineteen records of Idothea baltica, or fully 47 per cent., are 
for the month of April; and it has also further to be noted that, curiously 
enough, the whole number of the records, with only a single exception, 
are from surface tow-net gatherings.
