412 REPORT ON ZOOLOGY, MDCCCXLIV. 



OSTRACODA. 



Zaddach (ibid.) enumerates twenty species of Cypris, including five that 

 are new : C. flava, incana, reticulata, vulgaris, rulida. C. ornata, Jur., 

 Edw., is discriminated from ornata, Mull., and named C. jurinii. 



COPEPODA. 



Koch (ibid. 185) has formed two new genera, Doris (name of a genus of 

 Mollusca!) and Glaucea ; the former exemplified by Cyclops minutus, Mull. 

 (Moiwculus staphylinus, Jur.), the other to contain Cycl. rubeiis and cosrulea, 

 with which are associated the new species, Gl. cassia, hyalina, ovata. Another 

 new species is Cyclops dentatus. (Ibid. pt. 187.) 



SIPHONOSTOMA. 



Will (Wiegm. Arch. 1S44, i, 337, pi. 10, f. 1-9) has discovered in 

 Actiniae a parasite of this section, which he has distinguished as a new genus 

 under the name of Staurosoma. 



CIKRIPEDIA. 



Loven (Ofvers. Veteusk. Akad. Forhandl. 192, pi. 3 ; Horusch. Arch. 

 Skaud. Beitr. 434, pi. 3) has described a new species of Alepas, that lives 

 on the skin of Squalus glacialis and spinax, which he has named squalicola 

 accordingly. It is distinguished among the other species by its size, and 

 also by the softness not being confined to the shell, but extending also to 

 the legs and the parts of the mouth.
