 a shower of rain had fallen. 1 or five months ]n-cvious to this 

 rain there had been no rain upon the earth. Himalaya Moun-

Stre])focej)hohis texanus, n. sp. — The male differs from S. si- 

 mih'sj Baird, from St. Domingo, to which it is otherwise closely 

 allied, in the longer branch of the inferior antennae being much 

 longer and slenderer at tip (according to Baird's figure), while 

 the shorter branch is mucii narrower. In the female the ovisac 

 reaches to the penultimate segment of the abdomen, while ac- 

 cording to Baird's figure it scarcely reaches to the end of the 

 fourth segment from the end ; and the second antenn£e are repre- 

 sented as being much larger than in our species. The male 

 organs arise from the eighth segment from the telson and the 

 fifteenth of the body, and are simple, unarmed, slender, cylin- 

 drical, very long, and curled around (in alcoholic specimens) so 

 as to touch at their insertion. Total lengtli (male) '65 ; length 

 of longer appendage of second antenna; '17 inch ; caudal stylets 

 •13 ; length of male organs when extended -13 : female -55 long, 

 caudal stylet -11, ovisac "20 inch. " Waco, Texas. Found in 

 the summer in the same pool as the Limnadia was taken. The 

 pool was formed by the summer rain, and as it had passed a con- 

 siderable time in a dry condition, I suppose this species appears 

 much later, or at least not at the same time as the Limnadia^ 

 (G.W. Belfrage.) It also occurred in April, the females having 

 eggs, like those found in the summer of the year previous.
