"114 MATUTA GRANULOSA. 



palm is totally wanting in both sexes; Mr. Miers does not 

 make mention of this character. 



Matuta lunarls Herbst with its two remarkable varieties 

 occurs in the Indian and Pacihc Oceans, the Malayan Ar- 

 chipelago as far as the shores of N. W. Australia , and ap- 

 pears to be a rather rare species.

A very beautifully colored female specimen , collected on 

 the shores of the island of Amboina, was presented 

 by Mr. Ludeking some years ago. It belongs without any 

 doubt to Mat. granulosa Miers , though presenting a remark- 

 able variety as regards the coloration of the carapace, the 

 simple^ minute, dark red spots being disposed in symme- 

 trically reticulating strings which surround spotless places 

 that are smaller and more crowded anteriorly. In our speci- 

 men the carapace is also rather finely granulated , but 

 the granulation of the cephalothorax is known to be va- 

 riable in the species of this genus , as we have seen in the 

 Mat. victrix Fabr. The antero-lateral obtuse tubercles are 

 nearly equally developed as in Mat. hanksii Miers , but in 

 ,some less degree than in Mat. picta Hess. Tubercles of the 

 surface of the carapace , like those of the postero-lateral 

 margins very faintly marked. 



Lateral spines short , obtuse , slightly directed forward. 

 Front obtuse, very indistinctly emarginate, with the lobes 

 rounded. Ridge upon the outer surface of the hands with 

 five acute tubercles (no spines) , the second of which is the 

 largest , the fourth being also a little larger than the three 

 remaining. Lower part of the hand granulous ; close to the 

 inferior margin occurs a granular line , which proceeds on the 

 immobile finger, and is formed by some large round de- 

 pressed tubercles in the middle, that diminish gradually 

 towards the immobile finger and towards the external augle
