REPRODUCTIVE SYSTEM. 57 



head then enlarges, like the bud of a tulip on a footstalk ; 

 becomes globular; shows traces of dividing, and at last 

 splits into three, four, or five egg-shaped balls, which 

 finally separate as perfect ova. Within the peduncle, 

 the ovarian tubes branch out in all directions, and within 

 the footstalks of the branches (differently from what 

 takes place round the sack), ova are developed, as well 

 as at their ends. Close together, along the rostral 

 (i. e., ventral) edge of the peduncle, two nearly straight, 

 main ovarian tubes or ducts may be detected, which do 

 not give out any branches till about half way down the 

 peduncle, where they subdivide into branches, which in- 

 osculate together, and give rise to the mass filling the 

 peduncle, and sometimes, as we have just seen, sending up 

 branches round the sack. These two main unbranched 

 ovarian ducts, followed up the peduncle, are seen to 

 enter the body of the Cirripede (close along side the 

 great double peduncular nerves), and then separating, 

 they sweep in a large curve along each flank of the pro- 

 soma, under the superficial muscles, towards the bases of 

 the first pair of cirri ; and then rising up, they run into 

 two glandular masses. These latter rest on the upper 

 edge of the stomach, and touch the caeca were such exist ; 

 they were thought by Cuvier to be salivary glands. They 

 are of an orange colour, and form two, parallel, gut- 

 formed masses, having, in Conchoderma, a great flexure, 

 and generally dividing at the end near the mouth into 

 a few blunt branches. I was not able to ascertain 

 whether the two main ducts, coming from the peduncle, 

 expanded to envelope them, or what the precise con- 

 nection was. The state of these two masses varied 

 much ; sometimes they were hollow, with only their 

 walls spotted with a few cellular little masses ; at other 

 times they contained or rather were formed of, more or 

 less globular or finger-shaped aggregations of pulpy mat- 

 ter ; and lastly, the whole consisted of separate pointed 

 little balls, each with a large inner cell, and this again 

 with two or three included granules. These so closely
