both sides but better developed on the left. The rightuterua had one egg, 



the left 2. The right egg and one of the left ones had perfect shells, with 

 chalaza-like twisted and crumpled ends enclosing yolks with emhryos in 

 the early selachian stage. The other e^ r in the left uterus had the shelly 

 material equatorially girdling and somewhat constricting it. 



In the fourth ray both uteri were pregnant, hut the left was twice as 

 large as the right. Dissection being impossible at the time, both uteri 

 were preserved but have since unfortunately been lost. 



From all this data it seems not improbable that Pleroplatea maclura is 

 intermediate in stage between those rays having perfect bilaterality of the 

 reproductive organs, and those like Dasyatis say having complete 

 asymmetry in favor of the left side only. 



Aetobatus narinari (Euphrasen). 



SPOTTED STING-RAY. 



The specimens of this ray taken by Coles at Cape Lookout during the past 

 summer are chiefly remarkable for their great size and for their beautiful 

 markings. Three giants were taken : the first, a female, was 9 feet 6 inches 

 long over all, 7 feet 2 inches wide, and 18 inches thick; the second, a 

 male, measured 10 feet overall, 6 feet 11 inches wide, and 17 inches thick; 

 the third and largest, a female, was 12 feet in extreme length, 6 feet 11 

 inches wide, 20 inches thick, and was estimated to have weighed approxi- 

 mately 500 pounds. 



Mr. Coles was fortunate in getting some excellent photographs of the 

 second of the rays noted in the preceding paragraph, and these have been 

 finely reproduced in his 1913 paper. These rays were beautifully marked, 

 the hinder half of the body of each being covered jnot with white spots 

 hut with white ocelli with dark centers. 



In Mr. Coles' 1910 paper it is noted that the mother gives birth to the 

 young while leaping in the air. None of these young however were 

 secured. In 1912 Coles had the good fortune to catch a large female 

 (number 2 above) which gave birth to 4 young which were evidently near- 

 ing the time when they would have naturally been set free. In the photo- 

 graphs of the just spawned young the heads are very light in color, but in 

 that made of a young one preserved in formalin the head is as dark as 

 the body and the spots are few and rather indefinite. This change in 

 the ground color is due to the action of the preserving fluid. One of 

 these young was 286 mm. wide, 171 nun. long, and had a very slender 

 tail 634 mm. long. These are the first and only figures which have 

 ever been made of the young of AHobatus narinari.

EAGLE RAY. 



Dr. Smith (1907) gives but brief data for this ray, noting that it is 

 apparently not common in North Carolina waters. At Cape Lookout in 

 1909 Coles captured a female which gave premature birth to six young. 

 In 1912 (Coles 1913) he took 11 specimens, one being a female with 6 

 young. One of these young was 203 mm. wide, 124 mm. long, with a
