development of the hook of the first maxilla and in the great inequality in the length 

 of the two seise, arming the distal joint of the second maxilla. 



The shape of the body has been considerably altered, presumably by the method of 

 preservation. The segments are more or less separated from each other, and the whole 

 body considerably distended, so that it is impossible to get a fair idea of the normal 

 form. As it is, the specimen has not the compact, broadly oval, rotund form of the other 

 members of the genus. The body is nearly three times as long as broad, and the 

 epimeral plates seem to be more in evidence in dorsal view than in the figures of other 

 species of the genus. The length, moreover, is almost twice that of any other 

 species. The largest described form is L. Gardineri, Stabbing (1904), which is 7 mm. 

 long, while females of L. rotundicauda, with young in the brood-pouch, measure only 

 5'25 mm. The present specimen is 12 mm. long. 



The body is provided with setse only on the fourth and fifth segments of the 

 mesosome and the whole of the telson. In this respect it is more setose than 

 L. Gardineri and L. rotundicauda, but less so than in L. zeylanicus. 



The broadly oval inner branch of the uropods bears seven spines at its extremity, 

 and the outer branch, which is just slightly shorter than the inner, bears three spines. 



I prefer to leave the identity of this species an open question till more specimens, 

 not deformed or mutilated in any way, are available. In the meantime, the genus has 

 not, so far as I am aware, been recorded from South Africa previously.

This specimen agrees very closely with the specimens described and figured by 

 HANSEN (1895). I would point out, however, that both HANSEN'S specimen and my 

 own show four well-developed teeth on the dactylus of the first thoracic legs. 

 SCHIODTE and MEINERT (1879-84) show only three well- developed teeth and ;v 

 rudimentary one for G. linearis, but four well-developed teeth for (1. laticauda. In this 

 character, therefore, and in the shape of the eyes the present specimen approaches more 

 closely to G. laticauda (M.-Ed.), a Pacific species. On the other hand, this specimen 

 agrees so well with HANSEN'S specimens, and is so obviously the same species, that I 

 accept his decision as to the name it should bear.
