carbon isotopic analyses of these exposed carbonates should be similar to those of 
freshwater carbonates.

Florida. M. S.. Thesis, University of Miami., Coral Gables, FL. 69 pp. 
Parasites of Synodus foetens were studied from collections taken from Buttonwood 
Canal between January 1963 and December 1964. The fish were found every month 
except July 1963. They constituted year classes which remained in the canal for 
approximately one year. The diet of S. foetens included the pink shrimp, Penaeus 
duora rum, and a palaemonid shrimp; and the fishes S. foetens, Anchoa mitchilli, 
Lagodon rhomboides, Eucinostomus argenteus, Sphaeroides sp., Cvprinodon variegatus, 
Poecilia latipina, Gobionellus sp., a cyprinodontid, an atherinid, and others too digested 
to identify. The lizardfish was infected by Oodinlum sp., Sterrhurus musculus, 
Distomum fenestratum, Stomachicola maqna, Goezia minuta, a cestode described as 
Dibothrium tortum, Opecoeloides sp., several larval cestode plerocercoids, a larval 
Contracaecum sp., a larval ascarid, and a larval acanthocephalan. All of these are new 
locality records. Oodinium sp., D. fenestratum, G. minuta, Opecoeloides sp., 
Contracaecum sp., and the acanthocephalan and tetrahynch larvae are new host 
records. Extension of the geographic ranges for infection of S. foetens are recorded for 
Sterrhurus musculus, Stomachicola maqna, the pseudophyllid, and Scolex polymorphus. 
There is an increase in number of parasitic species with length of S. foetens up to about 
11 cm. The incidence of infection was higher in 1963 than in 1964 for all but Oodinium 
sp. and Opecoeloides sp. The difference between the two years was slight for Oodinium. 
Opecoeloides infected Synodus from February through June 1964 only. The only 
parasite to infect every fish was a tetraphyllidean plerocercoid larva in the pyloric 
caeca. Several factors appeared to play a role in the intensity of infection rates. There 
is a difference in infection rates among year classes. The monthly mean number of 
Sterrhurus per fish is negatively correlated with the mean salinity when Synodus 
lengths are held constant. The mean number of body cavity cysts is positively 
correlated with Synodus length when salinity is held constant. The mean number of 
Stomachicola has an inverse relationship with salinity, and the mean number of 
pseudophyllids has a slight inverse relationship with temperature. Possible reasons for 
relationships among these and other interacting factors are discussed. There is a 
positive relationship between mean salinity and the percentage of the pseudophyllid 
located in the posterior end of the intestine. Contingency tests indicate positive 
associations between the presence of Sterrhurus and Stomachicola, and among 
Sterrhurus, Stomachicola, and Goezia. Possible reasons for the associations are given.

Florida, including a description of a new genus of Cestoda. Bull. Mar. Sci. . 18:444-470. 
The parasites of the inshore lizardfish, Synodus foetens, were studied from collections 
taken from an estuarine canal in south Florida between January 1963 and December 
1964. A new genus of Cestoda (Bothriocephalidae) has been erected with the proposed 
name Anantrum. Several larval and adult helminths and a dinoflagellate were studied 
from monthly samples of samples of Synodus. Incidence of infection, intensity of 
infection, location of parasites in the host, and associations among parasites are 
discussed. Extensions of ranges for parasites in S. foetens and parasites heretofore not 
recorded from S. foetens are noted.
