in L. Catharinensis by Fritz Miiller. The stomach walls are capable of great 

 expansion, and the mouth opening is very large. Oftentimes the lips are 

 turned back, leaving the projecting tongue very prominent. When not feed- 

 ing, or when alarmed, the lips are pressed closely together, concealing the 

 tongue and closing the entrance into the stomach. The stomach walls are not 

 transparent, but contain many small pigment-dots and minute lasso-cells, 

 irregularly imbedded in their substance. 



There are two forms of tentacular appendages foimd on the bell margin. At 

 the end of each radial tube there is a tentacle which is long, hollow, and very 

 flexible. The surface of each such tentacle is covered with lasso-cells arranged 

 in rino-s surrounding the appendage. We thus have along its whole length 

 annulations of lasso-cells, alternating with smooth depressions. The correlation 

 between the stomach and tentacles is very well shown in this Glossocodon. The 

 voracity of Liriofe is mentioned by McCrady,* and in this animal it is equally 

 great. The abundant lasso-cells upon the tentacles and the lips are but neces- 

 sary to capture living food to satisfy an enormous appetite. 



In addition to the long tentacles there are four others likewise springing 

 from the bell rim. In the adult Glossocodon these appendages are wanting, 

 and in the oldest form which we found they were reduced to the mere "stump" 

 of a tentacle. We have, however, no drawing of our jelly-fish in which they 

 are not represented. Each of these appendages is situated midway on the bell 

 inargin, between two long tentacles. In the adult stage (fig. 1) they are club- 

 shaped bodies, united to the bell by means of a slender peduncle, and are 

 carried stiffly erect. They are solid, inflexible, and on their outer convex 

 surface there are clusters of lasso-cells arranged with regulai'ity. At the 

 position of union of the bell walls and the peduncle of this appendage there is 

 a slight spur or solid extension of the base on the outer surface of the bell, 

 extending upwards a short distance on the bell walls. 



The adult Glossocodon has eight otocysts, which are arranged on the outer 

 edge of the bell margin near the points from which the tentacles, long and 

 short, arise. Those which are found near the tentacular bulbs of the long 

 tentacles are placed at one side of the tentacle, and not at its very base. The 

 other set of otocysts are placed in the immediate vicinity of the origin of the 

 pedicle which bears the solid tentacle. There is but one kind f of otocyst 

 found on the bell margin, and it is a simple sac containing a single otolith. 

 The sexual organs hang like heart-shaped pouches from the four radial tubes. 

 They are sometimes so inflated that the walls of adjoining glands almost touch. 

 Their size and shape vary greatly, depending solely on the maturity of the 

 ova. Their color is white and sometimes pink. Male and female glands may 

 be found later to be distinguished by a diflerence in color, but little is known 

 of the diflerence of the sexes in Glossocodon. 



* McCrady saw L. scutigcra with its tentacles and lips seize a small fish "thrice 

 as large as itself" (op. cil., p. 209). 



t According to McCrady there are two kinds in L. scutigcra (o]}. cit., p. 208).
