LEPTOMEDUS.E — EUCOPE. 237 



Eucope dissonema. 

 Saphenella dissonema, Haeckel, 1879, Syst. der Medusen, p. 169, taf. II, fig. 5. 



Bell pyriform, with pointed apex, 5 mm. wide, 7 mm. high. The exumbrella is thickly 

 besprinkled with nematocysts. This maybe an indication of immaturity ( ?) Two radially 

 placed tentacles 180 apart. These have large, pyriform, basal bulbs and long, slender, 

 tapering shafts. 8 adradial lithocysts, each with a single concretion. Velum well-developed. 

 4 slender radial-canals. Manubrium spindle-shaped, about half as long as depth of bell-cavity, 

 and provided with 4 short recurved lips. Gonads sac-like, folded, and upon middle halves 

 of the 4 radial-canals. There is a short, conical, apical canal above stomach. Color ( r) 

 Development (?) Pacific Ocean, near the Hawaiian Islands. (See text-figure 123.) 



Eucope hyalina von Lendenfeld. 

 Eucope hyalina, von Lendenfeld, 1884, Proc. Linncan Soc. New South Wales, vol. 9, p. 920, plate 42, figs. 16-18. 



Bell flat, watch-glass-shaped, 6 mm. wide. Gelatinous substance thick at center. 8 ten- 

 tacles with conical basal bulbs, about as long as half the bell-diameter. 8 large adradial 

 lithocysts, each with 3 concretions. Lithocysts spherical and mounted upon sensory pads which 

 bear hair-like bristles. 4 large oval gonads on distal thirds of the 4 radial-canals, near ring- 

 canal. Stomach half as long as bell-radius and wider than long. Gonads and stomach pale 

 yellow, other parts colorless. Found in Sydney Harbor, New South Wales, Australia, in 

 September. 



Eucope annulata von Lendenfeld. 



Eucope annulata, von Lendenfeld, 1884, Proc. Linnean Soc. New South Wales, vol. 9, p. 602, plate 28, figs. 53—57. 



Medusa. — Bell ovate, evenly rounded, 2.5 mm. high, 2 mm. wide. 8 short, thick ten- 

 tacles one-third as long as bell-height. Basal bulbs small and without entodermal cores pro- 

 jecting into gelatinous substance of bell. 8 large, adradial lithocysts, each usually containing 

 2 concretions. Velum well-developed. 4 straight, wide radial-canals. Manubrium 4-sided, 

 prismatic, with a slight constriction in lower third; wide at mouth with 4 simple lips, narrow 

 at base. 4 oval gonads on distal thirds of the 4 radial-canals. Each gonad about one-fourth 

 as long as radial-canal upon which it is placed. Gonads yellow, other parts colorless. 



Irregular medusae with 5 radial-canals, produced by the forking of one ot the main 

 radial-canals, are common. 



Hydroid. — Stems 12 to 16 mm. high and arise from a creeping, reticulate, anastomosing 

 hydrorhiza. Stems are profusely and irregularly branched, the branches diverging at 

 acute angles, so that the general outline of the colony is pyramidal. The branches are 

 annulated throughout, the annulations being deeper near base than at ends of stems. The 

 hydrothecae thin, conical, and with simple, entire, unnotched lips. The hydranths have 

 a single verticil of 30 to 35 filiform tentacles and a wide mouth at the extremity of a flaring 

 neck. The gonothecae are club-shaped, elongate, with rounded outer ends, and are produced 

 at or near the axils of the stems. They have no annulated pedicels. Many medusa; are 

 produced in each gonangium. Perisarc light-brown. Entoderm of gonophores light and 

 dark-brown. 



Found on the coast of New Zealand, at Lyttleton. Medusae produced in June and July. 



Eucope falklandica. 



Phialella falklandica, Browne, 1902, Annals and Mag. Nat. Hist., ser. 7, vol. 9, p. 282. 



Bell 17 mm. wide and 1 1 mm. high, semiglobular, with thick walls. 60 to 70 tentacles with 

 large basal bulbs. 8 adradial sense-organs, each with 2 or more concretions. Stomach short 

 and quadrangular. Mouth with 4 lips with fringed margin. Gonads occupy nearly the whole 

 length of the 4 radial-canals. They hang down in wavy folds, not touching either bell-margin 

 or stomach. Found at Stanley Harbor, Falkland Islands, by Vallentin, and described by 

 Browne, who studied 8 specimens.
