52 REPORT OF NEW JERSEY STATE MUSEUM. 



tended frontal appendages about three times length of male 

 claspers. Sixth endites of all feet narrow and obtuse at end,' 

 gill variable in size. Color in life brilliant grass-green, with 

 nearly hyaline tint, and almost uniform throughout, except the 

 telson and last few abdominal segments, which are a deep rosy- 

 maroon color, deeping on caudal spines. Length 17 mm. 



Remarks. — This interesting species was first discovered by Mr. 

 W. P. Seal in ditches near Woodbury, where it was found abund- 

 ant. It was subsequently secured there, as late as March 27th, in 

 company with Bnbranchipus vernalis, as reported by Parkard. 



My only acquaintance with it was at Chincoteague, in Acco- 

 mac County, Virginia. On IMay 4th, 1912, I secured the ex- 

 ample described above from a little pond of fresh-water. This 

 pond was separated from a brackish-water inlet and glade by 

 only several feet of dry soil. Several fresh-water mollusks were 

 also found associated, besides Gamniariis fasciatus, Aselliis com- 

 munis, water-striders, water-boatmen, very many larval dragon- 

 fiies and a few Rana pipiens. The occurrence of this species in 

 Virginia is quite interesting, not only on account of the physical 

 location, but as indicating the most southern point at which it 

 is so far known to occur. 



According to Packard, the head of the female is simple and 

 without frontal appendages. Her egg-sac is small, short and 

 contains about a dozen very large eggs. He also gives her 

 size as slightly exceeding the male. 



The types of this species, embracing perhaps seven or more 

 individuals, are now in the Academy, but in such fragmentary 

 or imperfect condition that they cannot be used in the present 

 connection. They are labeled from, Woodbury, and bear the 

 names of J. H. Holman and W. P. Seal.
