legs 3 and 4 with a spine under ischiopodite. Abdominal segments without keels or 
spines. Telson nearly as long as uropods, which have exopodite and endopodite equal, 
and a blunt tooth at end of outer edge of exopodite. 
Length of longest specimen, 45 mm. 
Three specimens were taken at Station 96.

Sub-family PANDALINAE. 
Genus PANDALUS. 
Sub-genus PANDALUS. 
The name Dichelopandalus (Caullery, 1896) has been proposed for those members 
of this sub-genus in which the first leg is minutely chelate, and that of Stylopandalus 
(Coutiere, 1905) for those in which it is simple. Until, however, it is shown that the 
groups of species thus designated are in other respects natural divisions of Pandalus, 
it will be well to retain the type-subgenus intact.

The gill-formula of this species is that of P. montagui, and the first leg 
chelate.

The specimens agree perfectly with the descriptions of Pfeffer and Caiman, but the 
rostral formula may be higher than is stated by them. In a surprising number of the 
specimens the rostrum is damaged,* but several of the specimens show that the formula 
may reach p r There is no constant relation between the numbers of teeth above and 
below the rostrum, and their spacing shows a good deal of variation. There is more 
often one than two teeth near the tip. The rostrum is usually a little longer, but may 
* This appears to have been the case with that figured by Pfeffer.
