Description of Two New Phyllopocla 27 



thread-like manner, but is of the very same appearance as in 

 the other legs. 



The caudal part (see PI. V, fig. 3) does not exhibit 

 any essential difference from that in the female, either in 

 form or armature. 



Inner Organs. 



Though I have not had an opportunity of examining 

 the present Phyllopod in a living state, yet it has been 

 possible to study rather well the chief inner organs in situ 

 by rendering the body sufficiently pellucid in an artificial 

 manner. This is best accomplished by transferring the body 

 to oil of cloves, aftt,r it has been previously immerged 

 in absolute alcohol, and very slightly stained with some 

 colouring matter (hœmatoxyline or carmine) The body 

 may then be examined, either at once, or after having been 

 mounted in Canada balsam. 



The intestine (see PI. II, fig. 3; PI. V, fig. 3) forms 

 a cylindric tube extending through the axis of the body, 

 and terminating in the caudal part with a short muscular 

 rectum, that opens out between the caudal claws. Its 

 anterior part, in the region of the adductor muscle of the 

 shell, is suddenly bent downwards, and, immediately in 

 front of the mandibles, joins the short æsophagus, which 

 passes straight forwards from the oral orifice. Within the 

 head, a complicated secretory apparatus is contained, appended 

 to the foremost part of the intestine. This apparatus (see 

 PL III, fig. 1; PL V, fig. 4), which is generally regarded 

 as a kind of liver, consists of 2 symmetrical halves, eacli 

 debouching by a short duct into the intestine somewhat 

 laterally. The greater part of the organ occurs in the
