MARINE CRUSTACEANS. 751 



of the back of most Hippidea, marked witli fine transverse ridges, is repeated in Kraussia 

 and, more coarsely, in some species of Calappa. It is such striking and quite independently 

 evolved likenesses as these which lend strength to the view that the resemblances between 

 Hippidea and Oxystomes are due to convergence only, and not genetic. 



Family Albuneidae'. Genus Albunea Fabr., 1798. 



1. Albunea microps Miers, 1879. /. Linn. Soc. xii. p. 328. 

 Dredged in Mahlosmadulu Atoll in 20 fathoms of water. 



2. 1 Albunea speciosa Dana, 1852. U.S. Expl. Expd. Crust, i. p. 40-5. 



The telson in my specimen is more oval than in Dana's figure, and is pointed. This, 

 however, may be only a sexual difference (Dana does not state the sex of his specimens; 

 mine is a male) or the species may be variable or varietal in this respect. Dana refers to 

 and figures the eye-scales as one triangular plate between the eyes. 



The Blephanpoda fauriana of Bouvier {A7in. Soc. Ent. France, 1898) seems to be allied 

 to this species. Probably the genera Albunea and Blepharipoda meet near here. 



Taken at Hulule, Male Atoll. 



Family Hippidae. Genus Remipes Latr., 1806. 



3. Remipes testudinarius Latr., 1806. De Man, Zool. Jahrb. vi. Syst. p. 476. 

 Taken at Hulule, Male Atoll, between tide-marks. 



4. Remipes pacificus Dana, 1852. De Man, loc. cit. 



Taken between tide-marks in Male and Minikoi Atolls, and dredged in Huhile Velu and 

 Mahlosmadulu Atoll in 7 and 6 fathoms respectively. 



5. Remipes granulatus n. sp. (PI. LVIII. fig. 1.) 



Definition : " A Remipes with the carapace finely granular all over and raised into little 

 irregular lumps ; the front notched but without a middle tooth in the notch ; the outer teeth 

 of the fore edge not quite so long as those of the front and passing evenly into the side 

 edge of the carapace without an angle ; the post-frontal groove fairly distinct, behind this a 

 low irregular hollow on each side of the middle line, about a third of the length of the 

 carapace from its fore edge, and behind these again two half-moon shaped cracks in the same 

 position ; about 35 pits along each side of the carapace ; the eyestalks short ; the ' flagelhim ' 

 of the 2nd antenna of one joint only ; the end-joint of the first leg as long as the propodite, 

 slightly compressed, smooth on the inside, tufted with hairs here and there on the outside, 

 fi'inged above, below, and at the end ; and the last joint in the 2nd and 3rd legs short, broad, 

 bent at an obtuse angle."
