throat of one a number of little anguilktla-like worms, which he 

 likewise did not examine. 



In all the Terrapins the flesh, liver, and other parts than those 

 above mentioned were entirely clear of parasites. Therefore, in 

 preparing these animals for food, it is easy to free them from the 

 latter by rejecting the head, intestines, and bladder ; or if it is thought 

 desirable to use the intestines, they should be slit open and cleansed 

 of the contents. 



Prof. Leidy added that he had recently found in the collection of 

 the Academy a bottle labelled "alimentary worms in terrapin." 

 These proved to be seven bot-larvse like those described and exhibited 

 at a former meeting. (See Proc, 1887, 393.)

A Cnistaceaii Parasite of the Red S)iapper. — Prof. L,eidy remarked 

 that in the examination of the fish called the Red Snapper, Lutjanus 

 Blackfordi, brought to our market from Florida, he had observed a 

 curious crustacean parasite adhering to the throat about the pharyn- 

 geal bones. It appears to be an unde.scribed species of AncJwrella^ 

 which, from its having a bundle consisting of half a dozen posterior 

 appendages, including a pair of large ^"g^ pouches, may be named 

 A. fascicnlata. The animal is milk white, though in the fresh con- 

 dition the egg pouches are slightly reddish, and it is about half an 

 inch long, including the latter. The body is pyriform, with its long 

 axis in the same line with the single su.spensory arm, and with the 

 head and neck curved outward and a little downward to one side. 

 The head is bird-head-like in shape, with beak directed upward and 

 furnished with two pair of minute maxillipeds. The suspensory 

 arm, or brachium, about as long as the head and neck together, is 

 straight and is surmounted by a button, which is sessile and inter- 

 nally .striated. At the base of the brachium on each side there is a 

 minute papilla. The posterior appendages consist of two long cylin- 

 drical egg pouches, and on each side two much .shorter sausage-like 

 pouches. The adjoining figure is an outline of the parasite magnified 

 .six diameters. Twenty-five were obtained from one fish. Measure- 

 ments of a specimen are as follows : Length of body with brachium 

 2.5 mm. ; length of brachium 1.25 ; of head and neck 1.75 ; head 

 I by 0.625 : breadth of body 1.375 ; length of egg pouches 4, thick- 

 ness 0.625 ; length of short pouches 1.625 and 1.25. Clinging to 

 the head of one of the females of the Anchorella was a minute male 

 mea.suring 1.125 mm. in length. With the Anchorellae was found a 

 single .specimen of Ca/igKs, which closely resembles the C. namis,
