the Land Isopoda of Madeira. 67 



this species must be described, I propose along with that 

 description to give a list of the other species as yet known to 

 inhabit Madeira. 



Ligia italiea, Aud. & Sav. 



Among rocks about high- water mark ; common. 



Armadilloniscus tuberculatus, A. Dollfus. 



1889. Armadilloniscus tuberculatus, A. Dollfus, " Liste supplementaive 

 d'Isopodes des Azores," Revue Biol, du France, p. 392. 



Two specimens of this species recently described from 

 types procured by Lieut. Chaves in the Azores were found 

 by me among stones below high-water mark at Gorgulho, 

 near Funchal. 



Lucastus scitus, Budde-Lund (=PorceUio scitus, Budde- 

 Lund). 



Two specimens from Madeira are in Uljanin's collection 

 {fide Budde-Lund). 



Lucasius Normani, A. Dollfus, sp. n. (PL VI. figs, 1-4.) 



This new species has been submitted to M. A. Dollfus, who 

 has decided that it is not described, and has sent me the 

 following description, together with the figures which illus- 

 trate it : — 



" Body oblong, not broad, moderately convex, covered 

 with granulations, especially on the earlier segments; dorsal 

 surface finely setiferous throughout. Cephalon having the 

 lateral frontal lobes rounded ; central lobe well developed, 

 triangular, rounded, the summit blunt. Epistome a little 

 convex, but without any true median tubercle. Eyes with 

 fourteen ocelli. Exterior antennse equalling the length of 

 half the body ; the flagellum almost as long as the preceding- 

 joint, its first articulation half as long as the terminal. Poste- 

 rior margin of the person having a slight lateral sinuosity at 

 the sides. Pleon with the lateral processes well developed ; 

 the first pleopods in the male with the exopodite broader than 

 long and somewhat obtuse. Pleotelson much longer than 

 broad, with the sides slightly incurved and the extremity 

 subobtuse. Uropods having the basal joint one third shorter 

 than the pleotelson ; exopodite lanceolate, short ; endopodite 

 reaching to or very slightly extending beyond the end of the 

 pleotelson.
