MATUTA LUNARTS. 113 



described males. Distance from the ends of the lateral mar- 

 ginal spines 35 mm. Also belonging to the typical luna- 

 ris Herbst. 



4". A nearly adult male and two young female speci- 

 mens , without locality , belonging to the variety Uneifera 

 mihi. Carapace rather more finely granulated , antero-la- 

 teral tubercles somewhat more distinctly marked, those of 

 the surface less faintly developed, but those of the pos- 

 tero-lateral margins as faintly marked as in the typical 

 form. Lateral marginal spines slightly directed forward in 

 the male , quite straight in the females. For the rest loholly 

 agreeing with the true lunaris Herbst. 



5. Finally five specimens (2 cTi 3 9)i presenting the 

 characters of the Mat. circulifera Miers: Front distinctly 

 emarginate , with the lobes formed as in the variety Unei- 

 fera. Anterolateral and postero lateral tubercles , like those of 

 the surface nearly as- much marked as in the latter va- 

 riety; lateral marginal spines rather long, straight in the 

 male, a little directed backward in the female. Carapace 

 rather more coarsely granulated than in the preceding va- 

 riety, marked with strongly defined complete distinct cir- 

 cles, which however can also be distinguished in the male 

 specimen (N°. 4) that belongs to the variety Uneifera^ though 

 they are here very faintly defined by threadlike lines which 

 are as delicate as the other lines with which the carapace 

 is marked. For the rest entirely agreeing with the pre- 

 ceding specimens. 



It may be allowed to add a very striking character 

 to those given by Mr. Miers , by which the Mat. hi- 

 naris Herbst may be distinguished at first sight from the 

 closely allied Mat. victrix Fabr. In the latter species the 

 external angle of the palm at the end of the inferior mar- 

 gin is armed both in the male and in the female with a 

 conical spine, that is somewhat smaller than the strong 

 conical spine at the base of the oblique ridge on the outer 

 surface of the hand: in the Mat. lunaris Herbst however, 

 the fii'st-mentioned smaller spine at the external angle of the
