BRITISH NUDIBRANCHIATE MOLLUSCA. 



xm 



The second volume of Sir John G. Dalyell's f Powers of the Creator displayed in the 

 Creation' not having appeared in time to allow of our including the Nudibranchs there 

 described in our synonyms, we take the opportunity of giving a list of them here, with our 

 opinion as to the species to which they should be referred. This may be found useful in 

 consequence of the imperfect descriptions and figures of some of the species, concerning 

 which it is scarcely possible to form more than a conjecture. 



Tritonia Hombergii, Daly. — 



cervina = 



pimiatifida = 



punctata = 

 divaricata 



conifera = 



Doris verrucosa = 



argp = 



nodosa = 



cristata = 



clavigera = 



Eolis plumata = 



racemosa 



minor 



deaurata 



viridis 



sanguifer 



conspersa 

 inequalis 

 monoceros 



tenax 



histrix 



purpurea 



papillosa 



ventilabrum 



Tritonia Hombergii and T. plebeia, A. and H. Most of the 



smaller figures belong to the latter. 

 Dendronotus arborescens. 

 Doto fragilis. 



coronata. 

 May be D. pinnatifida, Mont., or a variety of the last. The de- 

 scription is not sufficient for identifying it. 

 Doto fragilis, a lusus. 

 Doris bilamellata. 

 tuberculata. 

 Goniodoris nodosa. 

 Ancula cristata. 

 Triopa claviger. 



Young of Eolis papillosa ? The branchiae are coloured green 

 in the figure, but in the description the colour is stated to 

 be " universally grayish ; tips of the branchiae clear." 

 Eolis picta ? 



Cannot be identified ; perhaps E. vittata ? 

 Eolis Glottensis ? 



viridis, most probably. 

 Cannot be identified; perhaps new, but it has somewhat the 

 appearance of a variety of E. aurantiaca we have met with 

 from deep water, with pale tips to the branchiae. 

 Eolis olivacea. 



tricolor ? 

 A lusus with the tentacles fused together at the base. Erom 

 the rings represented on the upper part of the tentacles, 

 the species is probably E. coronata. 

 Eolis rufibranchialis or E. lineata. 

 Drummondi. 

 coronata. 

 papillosa. 

 Embletonia pulchra.
