'Uropods very long and unusually narrow ; outer bearing very numerous 

 (twenty-five to thirty) spines on external margin, second joint about one 

 third to one half longer than broad. Inner margin of inner uropods with 

 numerous spines gradually increasing in length dis tally, and without 

 admixture of smaller spines. Length, three quarters of an inch, or 20 

 mm. The branchial appendage (?) of the second and following pleopods 

 in the male is completely coiled. 



The greatly developed rostrum at once distinguishes this species from 

 the other British representatives of the genus ; but another form from 

 the Mediterranean, Siriella frontalis, M.-Edw.,"^ bears a close general 

 resemblance, but the branchial appendages of the pleopods of male are 

 wholly different, and not coiled, and on this ground Glaus has instituted 

 a new genus — Pseudo siriella — for its reception. There are three spinules 

 at the termination of the telson in this species, and as many as fifteen 

 smaller spines are in the intervals between the larger spines on the sides 

 of the telson. 



I have examined specimens of this species from Firth of Clyde, 1865 

 (D. Robertson), Starcross, Devon, 1884 (C. Parker), Jersey, 1884 (Sinel 

 and Co.), Tarbert, Loch Fyne, 1885 (Scotch Fishery Laboratory), and 

 unmistakable drawings have been sent to me of specimens taken at 

 Plymouth (S pence Bate), and Castleton, Isle of Man (G. S. Brady). It 

 has been recorded from Torquay (Griffiths), and Weymouth (Wm. 

 Thompson). Milne-Ed wards's type was from ' Noimoutiers,' and Sars 

 took it in the Gulf of Goletta.

First sent to me as British by Mr David Robertson, who found it at 

 Helensburgh in the Firth of Clyde, and was (March 1886) taken by the 

 Fishery Board Laboratory among sand at low water, Tarbert, Loch Fyne.

 orgyarum, adque insulas Lofotenses, ubi unicum inveni exemplar' 

 (G. 0. Sars). 



It may at once be known from the other described species of the 

 genus by three oblique folds which are present down the sides of the 

 carapace. 



The above is the only species of the genus as yet known in the British 

 sea. Other closely allied forms which were included in this genus have 

 recently been separated by Sars, under the name Hemilamprops. Of 

 this restricted genus we have in Britain the following representatives. 

 ffemilamprops is a MS. genus of G. 0. Sars, which he has not yet defined. 



* Pseudosiriella frontalis, M.-Edw., is also a member of the British fauna. I 

 have a drawing made many years ago, at a time when I had no other Crustacea than 

 British, which undoubtedly represents the ? of this species, but unfortunately ho 

 locality is under the drawing. The specimen was probably one sent to me for 

 examination.
