the development of tlie young of Echinoderms from the egg with- 

 out the intervention of a locomotive " pseudembryo." As I have 

 already stated, I cannot, on account of the unfavourable conditions 

 for carrying on such investigations under which the majority of 

 the species were procured, say with certainty that no trace of 

 pseudembryonic appendages or provisional organs exists in any 

 of these instances ; but I feel satisfied that none such occur in 

 Psolus ephippifer, in the Kerguelen species of Kemiaster, or in 

 OpMocoma didelphys ; nor am I in a position to affirm that in 

 these high southern latitudes direct development is universal in 

 the subkingdom. I believe, indeed, that it is not so ; for species 

 of the genera Echinus, Strongylocentrotus, and Amhlypneustes run 

 far south, and a marsupial arrangement seems improbable in any 

 . of these. It is, however, a significant fact that while in warm and 

 temperate seas " Plutei " and " Bipinnariae " are constantly taken 

 in the surface-net, during our southern cruise between the Cape 

 of Good Hope and Australia only one form of Echinoderm 

 "pseudembryo " occurred ; and that we regarded with some little 

 doubt as the larva of Chirodota, from the presence of calcareous 

 wheels in the skin.

Note. — Since this paper was written, several notices of these 

 Kerguelen Echinoderms have appeared, both in this country and 

 in America, in connexion with the preliminary reports of the natu- 

 ralists attached to the Transit Expedition. As, however, this com- 

 munication is only intended as a preliminary sketch of some of 

 the peculiar phenomena of their propagation, and does not pretend 

 to accuracy in nomenclature, I have thought it better to allow it 

 to remain without alteration. When satisfactory descriptions 

 and figures are published, it will be necessary to go into the wholo^ 

 question of synonymy in detail. — C. Wy. T.
