On two sides of this hollow there are dark transverse lines rather more distinct on one side than on the other, indicating the com= mencement of the transverse rugae of the neck, mentioned in the description of this part in the perfect animal, in which the laminated earthy bodies are contained. About the central part of this projection there is an ill-defined oval space having a granular appearance, & containing some minute spherical particles of a dark colour, consisting apparently of a highly refractive material. See Plate 4, fig: 3. In this condition of the entozoon there is nothing in this space which has the slightest resemblance to the parts which are there about to be developed, namely, the hooklets, suckers, & earthy concretions; & it is only by the comparison of these obscure appearances with other specimens in which the development of the hooklets is a little more advanced, that their true significa= tion is to be learned - See Plate 4, fig: 4 & 5. Of these parts I will first describe the development of the hooklets, there being the most remarkable & charac= teristic organs of a Cysticercus. By comparing the preceding specimens with one in which some of the hooklets are in progress of development, & suf= ficiently advanced in their formation to
