3. Presented the paper, "A Gamut of Oral Neoplasms in Gunners, Tautogolabrus 
adspersus , (Osteichthyes; Perciformes; Labridae) Ranging From an Epidermal 
Papilloma to an Odontogenic Ameloblastoma," at the "Symposium on Neoplasms in 
Aquatic Animals as Indicators of Environmental Carcinogens" held in Cork, Ire¬ 
land, on 15-17 October 1974. The Symposium was sponsored by The International
