MATUTA BANKSII, 115 



of the iuferior margin : quite a similarly shaped granular 

 line is found in the females of Mat. banksii and Mat. picta. 

 Under surface of this finger somewhat granular like in the 

 two latter species. Ridge upon the immobile finger obsolete. 

 3Iat. granulosa appears to be very rare , our large 3fa- 

 <wto-collection containing but one single specimen of it. 

 It is found in the Eastern Seas , and may be distinguished 

 from the allied picta Hess and banksii Miers by the 

 characteristic ridge on the outer surface of the hand being 

 divided in both sexes into five acute ttiberdes , the second 

 of which is the largest. The female of our species differs 

 from the females of these two species by the fourth tubercle 

 of this ridge being no spine and by the acute tubercle at 

 the external angle of the inferior margin being ivanted. The 

 length of the carapace of our specimen measures 25 mm., 

 the distance of the ends of the lateral spines 35 mm.

The Museum contains, besides some typical specimens 

 without locality , rather very fine examples of the follow- 

 ing localities : 



1". Eleven specimens from the island of Amboina, en- 

 tirely agreeing with the above-mentioned figure, having the 

 carapace marked with numerous pink spots , that are crowded 

 together anteriorly and form large compound spots with paler 

 centre at its posterior portion. Last and penultimate joints 

 of the ambulatory legs marked with a large pink blotch. 



2*^. A female from the shores of the island of Ceram , 

 similar to the preceding specimens. 



3". A fine male from the Timor seas, also quite similar 

 to the Amboina specimens and presented by Dr. Wienecke. 



4". Four beautiful specimens, collected near the island 

 of Sanghir by Mr. Hoedt, wholly agreeing with the pre- 

 ceding but having the carapace otherwise marked, the 

 spots forming small curved lines and circles, that are lar-
