278 PROCEEDINdS OF THE NATIONAL MUSEUM. vol. xxxii. 



In front of the cirrus pouch, and at first parallel with it, the vagina 

 extends anteriorh" from the genital cloaca to about the median line of 

 the segment, thence back toward the posterior end. Behind the uterus 

 it becojnes slightly convoluted, passes toward the opposite face between 

 the two lateral ovarian masses, where it was observed in some cases to 

 expand into a seminal receptacle. It appears to receive a short duct 

 from the ovary — then the common duct passes to one side of the shell 

 gland, which it enters at the posterior end. Just before entering the 

 shell gland the common duct appears to be joined by ducts from the 

 vitellaria. The shell gland lies between the posterior extremities of 

 the two lateral ovarian masses. 



From the anterior end of the shell gland the slender oviduct passes 

 anteriorly, lying close beside the vagina, to open into the spacious 

 uterus at about the middle of the length of the latter organ. The 

 uterus lies between the anterior end of the ovary and the angle of the 

 vagina and its breadth in the maturest segments seen was equal to 

 nearly one-third the breadth of the segment. No ripe ova were seen in 

 any segments which were certainly from strobiles of this species. In a 

 few cases small spherical bodies were seen in the uterus which appeared 

 to be unfertilized cells from the germarium. The ovary lies near the 

 posterior end of the segment, and consists of two lateral masses on 

 either side of the median line, each of which is made up of a number 

 of small lobes. The vitellaria lie along the lateral margins from one 

 end of the segment to the other. Vitelline ducts were distinguished, 

 but their exact place of union with the duct leading from the seminal 

 receptacle to the- shell gland was not seen either in sections or in entire 

 segments. 



NOTf:S ON C. OCCIDENTALE MADE AT THE TIME OF COLLECTING. 



Angitd 7. — Of the 7 scoleces with strobiles the longest was 216 mm., 

 the shortest 30 mm. Aggregate length 1,4(>0 nun., average 200 mm. 

 Many free segments were found, also man}' still attached to the stro- 

 biles which separated easily from the chain. Most of these were 

 nearl}' circular in outline, with the diameter 1,5 mm.; a few were 

 slightl}' longer than broad, length 2 mm., breadth 1.5 mm. These 

 measurements were made on specimens killed in 70 per cent alcohol, 

 in which they shrink but very little. This is in marked conti-ast with 

 the behavior of the smaller form, C. i/nnus, which contracts very nnich 

 when placed in alcohol. 



Aiigiixt 10. — Length of strobiles, in formalin, 100 and 110 nnu. 



Augud l"l. — Several were found in one only of the two torpedoes. 

 There were many free segments, some of wdiich evidently belonged to 

 61 minus. In my notes I record the finding of fusiform ova in some 

 of the segments which I referred to C. occidentale. I have since 

 examined a number of these segments but have failed to find ova in 

 any segments which I could with certainty refer to this sjx'cies.
