Upon my request Prof. Döderlein of Strassburg lias been so 

 kind to send me for examination two of the 7 specimens from 

 Oran, which Dr. Ortmann (1. c.) has described under the name 

 of L. Edwardsii (Heller). These two specimens, middle-sized 

 females without eggs, 58 mm. and 61 mm. long, are unfortunately 

 much mutilated though, as Prof. Döderlein wrote, they are the 

 best preserved of the seven : no wonder, for these specimens have 

 been collected 80 years ago. In the smaller specimen the 2<1 legs 

 are wanting and of most ambulatory legs the propodi and dactyli 

 also and only in one specimen the shorter ramus of the outer 

 antennular flagellum is still preserved. 



The rostrum of the larger female that is distinctly trending 



upwards and extending 2 mm. beyond the antennal scales, is 



6+2 



— , — dentate, a formula which was also observed in a dutch 

 4 



specimen ; the 2'^ tooth of the upper margin is one and a half 



as far distant from the l^t as from the 3^. While in the typical 



species the shorter ramus of outer antennular flagellum measures 



invariably two-thirds the length of the peduncle, it appears in 



this specimen distinctly longer, the peduncle measuring 9,5 mm., 



the shorter ramus 7,5 mm.; the coalesced portion is 2 mm. long. 



The shorter ramus reaches by the whole free portion beyond 



the tip of the antennal scales and it extends 3,5 mm. beyond 



apex of rostrum, i. e. almost by half its length. Tiie 2^^ legs 



that are equal, project already by the chela and one-quarter of 



the carpus beyond the antennal scales. Merus 7,25 mm. long, 



carpus 8 mm. long, 0.9 mm. thick at the distal and 0,54 mm. 



at the proximal extremity, chela 8,25 mm. long (palm 4,75 mm., 



fingers 3,5 mm.); these numbers demonstrate that the carpus has 



a more slender shape than in the typical species and that it is 



hardly shorter than the chela, the difference being only 'z^,. The 



ambulatory legs, especially the propodi, are apparently also of 



a somewhat more slender form.
