Lar sabellariiiii. 



Diagram showing an irregular arrangement of the lobes of the stomach 

 and of the radial canals. 



specimens a variatiou occurred in the number of the canals which 

 leave the stomach ; normally six are present. Two specimens 

 possessed five canals : one belonged to the first stage and had five 

 tentacles ; the other belonged to the second stage and possessed ten 

 tentacles. 



Another specimen showed the union of two lobes of the stomach 

 to form one canal (fig. 7, p. 822), with an abnormal branching of 

 the canal near the margin of the umbrella. 



A specimen with seven canals showed that some of the canals 

 had less than the normal number of branches (fig. 8, p. 822). A 

 curious A'ariation of the normal star-shaped stomach is shown in 

 fig. 9 (p. 823). 



Laodice caLCabata. (Plate XLIX. fig. 4.) 



Laodice calcarata, L. Agassiz (1862); Haeckel (1879) j Brooks 

 (1895) ; Browne (1895). 



Lafoea calcarata, A. Agassiz (1865). 



According to Haeckel there are four species belonging to the 

 genus Laodice, viz. L. cruciata, L. ulothrix, L. calcarata, and L. sali- 

 narum. 



I have already briefly criticised (see P. Z. S. 1896, p. 482) the 

 numerous synonyms and references placed under the name oi Laodice 

 cruciata by Haeckel, and think that Medusa cruciata of ForskSl, and 

 the references connected with it, may be safely placed on an obso- 

 lete list, as neither the descriptions nor the figures are of any use for 

 even determining correctly the genus to which they really belong.
