328 H. F. BlanioYd—Gatahz/ue of Cyclones in the Bmj of Bengal [No. 4, 



Leno-th from the occipital crest to the end of the premaxil- 



laiies, 10-25, 1085 



„ from the anterior border of the foramen magnum,... 9-85, 8 55 

 „ of the bony palate from the opening of the posterior 



nares to the extremity of the premaxillaries, 4-7, 4-5 



„ of the upper molar series, 2-6, 2*85 



Breadth of palate between last molars, 1-63, 1-69 



„ between anterior premolars, 1"13, 10 



„ of the fossa between the pterygoid processes, 0-5, 075 



Greatest width of skull at posterior border of orbit, 5 3, 5*6 



Length of horns along the curve, 3575, 295 



Circumference of ditto at base, 9-0, 10 



Width from tip to tip of horns in a straight line, 16-5, 5'4 



Greatest breadth of horn at base, 2-25, 2-45 



Greatest depth of horn at base, 325, 3*25 



Width of forehead between orbits, 3-5; 3-8 



The lower part of the forehead at the nasal suture and the whole of 

 the frontals are more raised and convex than in either O. cycloceros, or O. 

 Vignei. 



The frontal ridge between the bases of the horns is less developed in 

 O. Blanfonli, and in this latter the posterior convex margin of the bony 

 palate is differently shaped, being more pointed and not nearly semicircular 

 as in O. cgcIoce?'os. 



Although this was promised me, I have not, I regret to say, as yet 

 received any skin of this sheep ; but I stould hope that the dimensions 

 above given, accompanied by an accurate drawing, would suffice to enable 

 other observers to identify this supposed new species. 



XVII. — Catalogue of the recorded Cyclones in the Bay of Bengal, up to the 

 end of l^^Q, compiled hy Henry F. Blanford, Meteorological Ee- 

 porter to the Gevernment of India. 



The following list was drawn up with a view to ascertaining with great- 

 er accuracy than had previously been practicable, what is the- distribution 

 of cyclones at the different seasons of the year, and also what parts of the 

 Bay are most liable to storms, in each season of the year. The general 

 results arrived at on these heads have been announced in my lately publish- 

 ed work " The Indian Meteorologist's Vade Mecum."
