ART. 18 SYNOPSIS OF CALA.NOID CRUSTACEA — MARSH 15 



Mass.; and Wiiley (1920) from several stations of the Canadian 

 Arctic expedition. Wiiley (1923) also reported it from Miramichi 

 Bay and Kiver, Labrador, from Hudson Bay, and from contents of 

 stomachs of shad caught in Scotsman Bay, Nova Scotia,

A long slender species. 



Female. — The wings of the last thoracic segment resemble those of 

 E. affinis but extend outward less; they are pointod or mnndeil. Th-r^ 

 first abdominal segment (pi. 14, fig, 9), like E. affinis^ is laterally 

 expanded in the proximal half and is narrowly constricted at about 

 the middle ; these expansions bear on each side a small spine. The 

 third abdominal segment is armed on the dorsal side with fine spines. 



The furcal rami are ciliate on the inner margin, and on the outer 

 margin distad of the lateral seta ; the dorsal surface like that of the 

 third segment is armed with fine spines. The length of the rami is 8 

 to 12 times the breadth. The first antennae are nearly as long as the 

 cephalothorax. The fifth foot (pi, 6, fig, 5) is like that of E. affinis. 



Male. — The male is slenderer than the female, and the last cephalo- 

 thoracic segment is rounded and not expanded into lateral wings. 

 Plate 6, Figure 4, shows the male abdomen, and Figures 6 and 7 the 

 fifth feet of the male. 



Length : Sars stated that the female reaches 1.15 mm, Nordquist's 

 figures made the male larger than the female, obviously a mistake. 

 According to Esterly, the female is 1.56 mm and the male 1.15 mm. 

 DeLint (1922), who made a detailed comparison of E. affinis and E. 

 hirundoides, considered E. hirwndoides much the smaller form. 



Occurrence. — Nordquist's description was from material collected 

 on the coast of Finland. Sars found it abundant on the coast of 

 Norway, Van Breemen (1908) and DeLint (1922) reported it in 

 Holland waters. In American waters Williams (1906) reported it 

 in Narragansett Bay; Sharpe (1910) and Wilson (1932) at Woods 

 Hole; Wiiley (1923). from Labrador and Nova Scotia; Esterly 

 (1924) from San Francisco Bay; and Campbell (1929) from Van- 

 couver Island. The author found it in Big Timber Creek, Glou- 

 cester, N. J., on September 19. Big Timber Creek is connected
