their margins in the deep fnrrow in the first segment of 

 the triincus and of the epistoma, most accuratel}'. Also the 

 split hind corner of the first segment of the trunciis encloses 

 exactly the even split epimer of the second segment. 



The articnlar face of the segments, pronotum, is ver}'^ 

 short, almost linear. In all the examined species has the 

 first pair of pleopods in the female most often a well developed 

 area opercnlaris; the uropods with their appendices are ex- 

 tremely short and minute. 



Here I record the following species: 



a. Epistoma supra sulco transverso deletiore. 



Seg-inentum primuni trunci sulco luargiuali angustiore, ante minus 

 profundo et leviter curvato. 



b. Superficies Isevis. nitida, punctatissima.

 Armadillo officinalis Dum. — B.-L, Crust. Is. Terr. 16. 

 Patria: South Europe, Asia minor, North Africa. 



2. Armadillo erythroleucus. 



Arm. officinali statura et habitu persimilis, indicibus 

 sequentibus maxime differt: 



Sulcus transversus epistomatis subdeletus. 



Lamina interior epimeri segmenti primi trunci major; 

 lamina interior epimeri segmenti secundi minus crassa 



Telsum supra in medio basis fovea perparva, oblonga. 



Uropodum scapus longior; exopoditum ab apice scapi 

 magis remotum. 



Color albide rufescens. 



Patria: Crimea. (Mus. Varszava). 



bb. Superficies opaca, minutissime et densissimc squamata. 

 c. Lacinia interior segmenti prinii trunci manifesto longior quam 

 lacinia exterior.
