Srh^roma tristense, Leach. 

 1818. Sphceroma tristense, Leach, Diet. Sci, Nat., vol. xii., p. 345. 

 1843. S. t., Krauss, Die Sudafrik. Crust., p. 65. 



Taken in Table Bay. Krauss says : " The two longish 

 tubercles on the terminal segment and the blunt end of the 

 pleon determine me to regard my specimens as belonging 

 to this species very briefly described by Leach ; at any rate 

 they belong to that section of the genus in which the last two 

 segments of the peraeon are shaped like the preceding ; but 

 all the segments have in the middle four very obscure 

 tubercles and on the sides a similar intumescence. The 

 branches of the uropods have smooth margins and are just 

 as long as the apex of the pleon." Length 5"2 lines. 

 1905. <S'. t., Hansen, Quarterly Journ. Microsc. Sci., vol. xlix., pt. 1, 

 p. 117. 

 Hansen bays of this and several other species hitherto 

 included \n this genus, that they " do not belong to 

 Sphceroma, but 1 cannot refer them to genera, because the 

 descriptions and figures are too defective in some respects." 



Sph^roma jurinii, Audouin. 



1825. SphcBToma jurinii, Audouin, Explication sommaire des 

 Planches, for Savigny's Egypte, pi. xii., fig. 2. 

 Savigny's figure agrees with Leach's S. tristense in having a 

 very short seventh isegment of the peraeon and the telsonic 

 segment ending abruptly in an obtuse point, but the obscure 

 elongate tubercles at its base are wanting.
