from the island ot' Cyprus ; a species closely allied to the 

 former, from Asia ]\linor ; ^f. ori'eutalis, Gmel., from Nortliern 

 Persia ; M. ]'i)pHi\ Blyth, from Chorosan ; ^f. (irkal, Br., 

 from Tureomaiiia ; and M. Jhirc/ieUi, Blvth, from tlie llima- 

 layas. 



Tliis genus, in the sliape ot tlie horns, sliows an ap})roach 

 to the goats ; and the above-named species of Ammotrayus and 

 ^^yocei-os are closely allied to it. The former, being built like a 

 sheep and having horns exactly like d^/.s/»io« ry^>/v'«.s', wants the 

 lacrymal fossw 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- 

 yelaphus. The latter, besides thcAvant of the lacrymal fossae, 

 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 Musliaoii. These 

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

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

 ^S". FaUasii, 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 Avill be well to state their specific differences 

 before going on to their more detailed description.

" On the Development of the Crustacean Embrjo, and the Varia^ 

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

 thalmia." By C. Spence Baie, F.R.8. 



The author states that, although the general forms of several 

 genera of Podophthalmous Crustacea are kno\ATi, 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
