Entima insignis, Haeckel (1879) ; Garstang (1894) ; Browne 

 (1895). 



A single specimen taken at; Plymouth on 3rd October, 1893. 



Umbrella t mm. in width and 3| mm. in length. Stomach 

 about 2 mm. long, situated on a peduncle 7 mm. long. Mouth 

 with four large lips. Four very long perradial tentacles, about 

 20 mm. in length when fully expanded, with a pair of cirri at the 

 base of each. About 30 marginal bulbs, each with a pair of cirri. 

 Eight adradial marginal vesicles, each with 2-5 otoliths. The 

 gonads are on the lower half of the peduncle along the radial 

 canals. The medusa is perfectly colourless. 



Another specimen taken at Plymouth on 7th September, 1895. 

 Umbrella 8 mm. in width and 4 mm. in length. Thirty-nine 

 marginal bulbs, which are not evenly distributed upon the margin 

 of the umbrella ; the four quadrants of the umbrella possessing 9, 

 13, 7, and 10 bulbs. The gonads are just commencing to develop 

 upon the radial canals, close to the stomach. The marginal 

 vesicles with 3-4 otoliths. In other details the specimen resembles 

 the one described above.

Saphenia mirahilis, Haeckel (1879) ; Cunningham (1891) ; Bles 

 (1892) ; Garstang (1894) ; Browne (1895). 



Cunningham obtained some hundreds of specimens off the 

 Eddystone, at night, on 16th July, 1891. The largest 12 mm, in 

 diameter. 



At the end of September 1893 I found two specimens at 

 Plymouth having the umbrella about 6 mm. in diameter, and eight 

 marginal vesicles each with three otoliths. During September 1895 

 I met with a few more specimens at Plymouth. One specimen 

 5 mm. in width and 5 mm. in length. Eight marginal vesicles 

 with 1-5 otoliths, but the majority possessed 3 otoliths. Two 

 long opposite, perradial tentacles, with a pair of cirri at the base 

 of each. Thirty-nine marginal bulbs, not evenly distributed 

 between the radial canals ; a pair ofcirri usually present on each 

 bulb. Manubrium very long. Medusa colourless. 



A very small medusa taken on 16th Sept., 1895, may possibly be 

 the earliest free-swimming stage of Saphenia (Plate XVI. fig. 5 and 

 fig. 6 a). Umbrella bell-shaped, slightly longer than wide ; about 

 I mm. in length. Manubrium about one quarter the length of 

 the umbrella-cavity. 



The stomach is not on a peduncle, but has a short conical knob 

 at its base extending into the mesogloea of the umbrella and 

 terminating in a short apical stalk, which does not reach to the 

 ex-umbrella. 



On the margin of the umbrella, two opposite, perradial tentacles, 

 with a pair of cirri at the base of each ; two opposite, perradial
