Order Mysidacea.

The depths at the 12 stations wbere this species was found, 
varied from 900 metres (492 fathoms) at St. 32 to 2600 metres 
(1420 fathoms) at St. 58, while the nets were fishing from 1000 metres 
(547 fathoms) to 2500 metres (1366 fathoms). The species is, appa- 
rently, by no means rare in the deeper waters of the Medìterranean, 
so that its absence from the collections of the Maia is rather sur- 
prising as several gatherings were made over suitable depths du- 
ring that emise. 
Dr. Lo Bianco has given some interesting notes on the colours 
of this species in bis paper on the results of the Puritan gatherings. 
Family Lophogastridae. 
13. Lophogaster typicus M. Sars. 
L. typicus^ Lo Bianco (1901 and 1903). 
The specimen from station 29, 1902, is a male (15 mm long) 
and agrees with the same sex from the Challenger collections in 
having the median fork of tbe rostrum equal to the two lateral 
forks though the rostrum as a whole appears somewhat longer than 
in Sars' figures, since it extends quite half way along the terminal 
joinfc of the antennular peduncle. There are 6 teeth on the outer 
margin of the antennal scale in addition to the streng terminal spine. 
The lateral spines on the carapace, immediately behind the eye 
and in front of the gastro-hepatic groove appear to be more acute 
than I bave ever observed them in females. 
The lateral margins of the telson are armed with 4 spines, the 
additional pair being placed anterior to those figured by Sars in 
bis Challenger work. There are 5 teeth on the apex of the telson 
between the streng lateral spines. On the sterna of the 2. to the 
7. thoracic segments and on the first 5 abdominal segmenta there 
is a rather long very acutely pointed and somewhat forwardly di-
