* Grube describes the tentacular membrane (as he calls the cirri round the 

 mouth} of Dujardin as being " (i-fariam laciniata, laciniis iterum incisis," which 

 does not agree ^\'ith Pallas's description of his Lumbricus phatlokhs, and which, 

 indeed, would ahnost place this species in the genu-s T/icmiste of Gray (JJcndro- 

 stormvm of Grube). The habitat, Punta Arenas in Central America, is not, how- 

 ever, very widely apart from that given by Pallas, " Shore of the island of 

 Grenada in the West Indies." 



+ Pallas refers the saccatus of Liimfeus, with a doubt, to his species L. phal- 

 loides. it only differing in the skin which covers it being rendered lax by having 

 been badly preserved in spirit.-".
