I have never seen Dana's species, but the others are common, 

 D. eoecinea especially. 



I am at present engaged on a review of the whole genns, 

 including its bibliography, which I hope to publish shortly. A 

 marked difference between the present species and I), eoecinea is 

 mat the latter lias a small line of branchlets projecting at right 

 angles from the main stem, while the stems of D. Uvida are smooth.

 The lumbar plexus is constituted by the three last lumbar nerves. f

* In a previous paper on the anatomy of the brachial plexus (Pro. Linn. Soc., 

 N.S.W., Vol. III. p. 409.) I omitted to mention, (1.) that the specialised 

 cutaneous muscle named expansor secundariorum by Mr. A. H. Garrod 

 is supplied by a branch from the Internal cutaneous nerve; (2) that a 

 special slender twig to the coraco-stemalis originates from the second 

 nerve of the plexus. 



1 The determination of the posterior vertebras — as lumbar, sacral or caudal — 

 is made to depend on their relations to the nerves There is a difficulty 

 in applying this test to the distinguishing of the posterior cervical and 

 anterior dorsal vertebras— the relations of the nerves of the brachial 

 plexus to the first vertebra bearing a movable rib being cpiite inconstant.
