Dr. A. Philippi's Zoological Notices. 95 



noticed another differently formed, and short ciliated lamella, 

 fig. g. I moreover found three pairs of falcate palpi or foot- 

 jaws with long cilia, fig. c. I did not, however, succeed in ob- 

 serving the other cibarian organs. 



Notwithstanding the imperfection of these observations, 

 they still sufficiently prove the independence of this genus. 

 It differs from Cypris; 1. by the incision of the shell; 2. 

 by the existence of two eyes; 3. by the broad hook-bearing 

 tail ; 4. by having only two pairs of foliaceous feet ; 5. by pos- 

 sessing peculiar organs for bearing the eggs, which function 

 in Cypris is performed by the third pair of feet. Asterope is 

 distinguished from Cypridina; 1. by the incision of the shell; 

 2. by the presence of only two pairs of foliaceous feet; 3. by 

 its simple tail (in Cypridina it consists of two lamellae), &c. 

 Cytherina differs from Asterope ; 1. by the want of the incision 

 of the shell; 2. by the presence of four pairs of feet, as quite 

 correctly stated by O. F. Muller; 3. by the tail consisting, as 

 in Cypridina, of two lamellae. *(I have observed about eight 

 species of Cytherina near Naples.) 



The generic characters were accordingly as follows : — 



Testa bivalvis, corpus abscondens, antice subtusque incisa. An- 

 tenna duse simplices, apice penicillatae. Oculi duo ! Pedes 

 quatuor compressi, subfoliacei. Fila peculiaria ad retinenda 

 ova. Cauda compressa uncinis pluribus terminata. 



The species might be characterized in the following man- 

 ner : — 



Asterope elliptica. A. testa exacte elliptica, nitida, sublente for- 

 tiori, punctis opacis albis adspersa. 



Plate III. Fig. 9. Asterope elliptica, Phil. Magnified. 



A. Its natural size. 



Fig. 10. The left shell, inside view, moderately magnified. 

 Fig. 11. The animal magnified sixty times. 



B. One of the four lamellae attached to the base of the feet, still 



more highly magnified. 



C. One of the three pair of lamellae, which are situated near the 



cibarian apparatus. 

 g. The lamellae between the feet and tail. 



4. Short characteristic of several new Genera of the Family 

 of the Copepoda. 



During the great heat of the summer months I have occu- 

 pied myself in Sorrent in examining the minute animals which 

 live among the small Algae. Here dwell, only to speak of the 

 Crustacea, especially Caprellce, some Dynamene, Janira, Jassa, 

 Juera, which latter three appear to be very rare ; numerous
