from the island of Cyprus ; a species closely allied to the 

 former, from Asia Minor ; M. orientalis^ Gmel., from Northern 

 Persia ; M. Vignei^ Blyth, from Chorosan ; M. arkal, Br., 

 from Turcomauia ; and M. Burchelli, Blyth, from the Hima- 

 layas. 



This genus, in the shape of the horns, shows an approach 

 to the goats ; and the above-named species oi Anmotragus and 

 ^goceros are closely allied to it. The former, being built like a 

 sheep and having horns o.'s.n.ciXjWke.Musimon cypn us jWants the 

 lacrymal fosste of the goats in front of the orbit in consequence 

 of the small development of that bone ; there is also no ridge 

 on the nose. The only species inhabiting Africa is the tra- 

 gelaphus. The latter, besides the want of the lacrymal fossas, 

 differs also in its structure, being built like a goat, in the short 

 skull and the beard which is found on male specimens ; in the 

 shape of the horns only does it resemble j\[usimon. These 

 latter are almost smooth, in which this form differs from the 

 sheep as well as from the goats ; it is the Caucasian species 

 u^. Pallasii^ Rouill. Another species, which also possesses a 

 beard and ovine horns, occurs in Cabul (Journ. Asiat. Soc, 

 of Bengal, 1840, p. 440 ; Wagn. Fortsetz. v. Schreb. 1844, 

 Suppl. iv. p. 540, note). 



Having in this way fixed (by help of comparative diagnosis) 

 the position of the Turkestan sheep in systematic classifica- 

 tion, I think it will be well to state their specific differences 

 before going on to their more detailed description.

" On the Development of the Crustacean Embryo, and the Varia- 

 tions of Form exhibited in the Larvae of 38 Genera of Podoph- 

 thalmia." By C. Spence Bate, F.R.S. 



The author states that, although the general forms of several 

 genera of Podophthahnous Crustacea are known, yet the details 

 of their structure have been so unsatisfactorily figured and de- 

 scribed, that the value and importance of hereditary elements are 

 incapable of being studied and appreciated. 



Through Dr. Carpenter he received from Mr. Power an offer of 

 a considerable number of larva? of exotic species, together with
