specimen from this locality has on the rostrum 5 dorsal teeth and 

 3 very small ventral teeth. 



With all Europe in the throes of war (August 17, 1914), this little 

 species is a fitting representative of Peace, in honour and hope of 

 which I name it. 



Gen. EXHIPPOLYSMATA, nov. 



1914. Ilippolysmata (part), Kemp, Eecords of the Indian Museum, 

 vol. 10, pt. 2, p. 112. 

 Closely allied to Lysmata, Eisso, and Hippolysmata, Stimp- 

 son. Eostrum longer, usually much longer than carapace, 

 with an elevated dentate basal crest ; telson lanceolate, the 

 acute apex unarmed. Upper flagellum of first antennae 

 elongate, its basal portion apparently composed of two 

 coalesced branches, the shorter free only at the apex. 

 Mandibles without palp, the molar comprising a broad 

 spinuliferous band and by its side a projecting dentate 

 plate. In the first maxillipeds the endopod has a small 

 conical joint at the apex tipped with a spinule, the preceding 

 joint a little wider and about two and a half times as long. 



Mr. Stanley Kemp has recently (April, 1914) given a key to 

 the Indian species of Hippolysmata, separating a new species, 

 H. ensirostris, with a variety punctata, from the rest by 

 characters of which I have made use for instituting the 

 present genus. The Indian species is said to be very 

 variable in some of its features,, so that it may be a question 

 of taste whether nearly related forms shall be treated as 

 named varieties or as distinct species. 



EXHII'POLYSMATA TUGELAE, n. Sp. 



Plate LXXXIX. 



The dorsal crest is composed of 13 graduated teeth increasing 

 in size towards the front, with a small tooth at a little distance on 

 the carapace to the rear and another at a small distance on the 

 rostrum in front ; just behind the latter tooth begins a row of 7 

 ventral teeth, at first at small then at large intervals, while above 

 all but the first the dorsal margin is perfectly smooth. The rostrum 

 measured from the base of the eye-stalk is once and a half as long 

 as the rest of the carapace ; the antennal tooth and the antero-lateral 

 are acute and pronounced. The telson is very like that of E. cnsi-
