fathoms: Mus. Nor. Galley Head, Co. Cork; off Skilligs 

 and off Bull Rock, S.W. Ireland {A. 0. W.) ; 70-80 miles 

 off Spurn Head {T. S.) ; Loch Fjne {Sir J. Murray). 



Distrih, Floro and Hardanger Fiord, Norway, down to 

 150 fathoms; Vadso, East Finmark ; Fosse de Cap Breton, 

 Bay of Biscay, 30-60 fathoms (A. M. N.) : Mus. Nor. Sars 

 speaks of it as one of the commonest Lysianassidae of the 

 Norwegian coast. Denmark {Meinert) ; west coast of France 

 {Chevreux) ; Mediterranean [Sars (& Delia Valle). 



Genus 19. Schisturella *, gen. nov. 



Allied to Tryphosa and Uristes, and in the structure of 

 the niaxillipeds agreeing with the latter in having the 

 masticatory lobe scarcely reaching to the end of the ante- 

 ])enultimate joint of the palp, which is elongated, its terminal 

 joint claw-like. Epimera of first segment of mesosome rudi- 

 mentary and almost entirely concealed by the epimera of the 

 second segment. Antennules and antennse without calceolse. 

 Eyes well developed. First gnathopod with oblong hand, 

 the palm very oblique. Telson divided to the very base, so 

 that it consists of tioo pieces. 



42. Schisturella pulchra (H. J. Hansen). 



1887. Tryphosa pulchra, H. J. Hansen, (141) p. 78, pi. ii. figs. 6-6 e. 



Hah. ' Porcupine,' 1869, a single specimen taken, Stat. G-j, 

 lat. 61° 10' N., long. 2° 21' W., 345 fathoms. This is to the 

 N.W. of Shetland and exactly on the line which I have pro- 

 posed should form the limit of the British area. 



Distrib. Four examples are in the Copenhagen Museum 

 which were taken on as many different occasions in the Green- 

 land seas in 15-100 fathoms. 



The ' Porcupine ' specimen agrees closely with Hansen's 

 description and figures. The figure shows a dorsal sinus on 

 the fourth segment of the metasome; there is no such sinus 

 in my specimen, and Hansen in his description says " Seg- 

 mentum quartum caudai dorso integro, non carinato." Of the 

 third segment Hansen writes, " Angulus infero-posterior 

 segment! tertii caudae rotundatus incisura perparva supra 

 angulum in margine posteriore adest." 1 should have rather 

 described it as a spine-point placed rather above the angle 

 (iSars's figure of the same segment in Calliopius Rathkei 

 gives an idea of it, the spine-point, however, being a little 



* o-x'fToj, divided, ovpa, tail. I have adopted the form Schisturella, 

 because Schistura is in use, as is also Scissiirella.
