first species of this family {NotodeJphxjs ascidicola) discovered by 

 Aliman was regarded by that naturaUst as closely allied in its orga- 

 nization to the free Copepoda, although its mode of life and some 

 modifications in the buccal and natatory appendages seemed to ap- 

 proximate it to the parasitic Crustacea (Siphonostoma). He regarded 

 it as a free Copepod living in the respirator)^ cavity of an Ascidian, 

 as the Pinnotheres are true Brachyurous Decapods residing in the 

 cavitv of the mantle of the PinncB. This view is now confirmed by 

 Thorcll, who detects a nearly perfect identity between the appendi- 

 cular organs of the NotodelphyidcB and those of the free Copepoda. 



These little Entomostraca are found clinging to the inner wall of 

 the res[)iratory sac of the Ascid'ans by means of the antennae of the 

 second pair. Only one species (Boiachus cylindricus, Thor.) resides 

 between the two lamellae of this sac. Notwithstanding this parasitic 

 mode of life, they possess buccal appendages adapted for mastication. 

 They appear, therefore, to derive their nourishment, not from the 

 fluids of the Ascidian, but from the Infusoria and organic particles 

 which float in the circumambient water. The most remarkable pe- 

 culiarity of structure presented by these animals is that which gave 

 occasion to the name of Notodelphys, given to them by Aliman. 

 It consists in the presence, in the females, of a pouch situated beneath 

 the integuments of the back, and destined for the reception of the 

 ova on their emission from the ovary. This pouch therefore replaces 

 the external ovigerous sacs of the other Copepoda. 



The present memoir contains a new classification of the Copepoda, 

 which, according to the author, include the Siphonostoma. i\\ this 

 he concurs with Steenstrup and Liitken. He divides these Crustacea 

 into three series — Gnathostoma, Po^cilostoma, and Siphonostoma. 

 The second of these, establishing the passage between the masticatory 

 (Gnathostoma) and the sucking Copepoda (Siphonostoma) is of new 

 formation. It includes the Corycceidce, Eryasilidce, Sapphirinidce, 

 MirucidfB, and some other small families. It is distinguished from 

 the Siphonostoma by the want of the sucker, and from the Gnatho- 

 stoma bv the absence of mandibles. — Kongl. Vetensk. Akad. Handl.
