8.5 mm. long, carpus 7 mm., palm 7 mm., fingers 6,5 mm., palm 



2.6 mm. broad. 



The other female measures 81 mm. The rostrum hardly reaches 



2 mm. bevond the scales aud is rather little upturned distally, 



so that the apex is situated in the same horizontal line as the 



7 + 1 

 2^ tooth of the upper margin ; it is — - — dentate, the 3^1 tooth 



immediately before the orbital margin and the 2d one and a 

 half as far from the !«' as from the 3^. Distance between the 

 foremost tooth and the apex little more than Y3 the length of 

 the rostrum. Third tooth of the lower margin situated immedia- 

 tely before the foremost tooth of the upper and just before the 

 penultimate joint of the antennular peduncle. 



The antennular peduncle extends hero also to the distal quarter 

 of the scaphocerite and is 13 mm. long; the shorter ramus, 11,5 

 mm. long, appears a little shorter than the peduncle, exactly as 

 in the typical L. serratus from the coast of Belgium. T/ie shorter 

 ramus, fused f o the long er onhj for one-fifth lts length, extends hg 

 four-sevenths, viz. 0,5 mm., begond apex of rostrum. 



The mandibular palp (Fig. 5) resembles that of the ova-bearing 

 female, the 2*^ joint being also l,7-time8 as long as thick: the 

 Ist or basal joint is namely 0,9 mm. long, the 2<i 0,51 mm. 

 long and 0,3 mm. thick, the 3^ 1,16 mm. long and 0,24 mm. 

 thick at base, being almost 5-times as long as thick at base. 



The external maxillipeds extend by half the terminal joint 

 beyond the antennal peduncle. 



The legs of the l^t and of the 5^^ pair reach as far forward 

 as the terminal spine of the scaphocerite. 



The 2<l legs reach by hardly more than the fingers beyond the 

 scales: merus 7,5 mm. long, carpus 7 mm., palm 6.25 mm., 

 fingers 6 mm., the palm being 2,4 mm. broad. 



As follows from these observations, the two specimens differ 

 from those that have been referred to the typical L. serratus 

 1" by the somewhat different form of the mandibular palp, 2'^ by 

 the shorter ramus reaching, in the adult species, considerablg
