I. '08. 82 



Without older intermediate specimens it is, of course, quite 

 impossible to be at all certain of the affinities of this larva ; 

 attention may, however, be drawn to the very close resemb- 

 lance between its branchial formula and that of Nematocar- 

 cinus. The only gill w^anting in the larva is the podobranch 

 at the base of the second maxillipede, and this (1906, pi. xv, 

 fig. 7) is represented by a papilla. 



This larva has been found on the following occasions : —

Family BRESILIIDAE. 

 Genus Bresilia, Caiman. 

 Bresilia atlantica, Caiman. 

 PL X, figs. 1-7. 

 Bre-silia atlantica, Caiman, 1896, Pis. i and ii, figs. 1-18. 



The specimen traw^led by the Flying Falcon expedition 

 of 1888 and described as a new species, Bresilia atlantica, has 

 hitherto remained unique and the only representative of the 

 family created for it. During the last two years four more 

 specimens have been caught off the Kerry coast ^^'hich agree 

 in almost every detail with Caiman's careful description and 

 figures. 



Caiman, when describing the species, stated that there was 

 very little doubt that the type had assumed adult characteris- 

 tics, but more recent investigations have demonstrated such 

 astonishing differences betw^een the post-larval and adult forms
