PLATE 2 



Fig. 13. Amphulinium pacificum sp. uov. Colored by 0. Swezv. Ventral view. Note the 

 refractive granules, probably the products of metabolism, and chromatophores in the body. 

 X 626. 



Fig. 14. Gymnodinium hicorne sp. nov. Camera drawing by Miss Ruth Merrill. Lateral 

 view. X 1102. 



Fig. 15. Cochlodinium vinctum sp. nov. Viewed from left side. Note the food body closely 

 embedding a superficial mass of oil droplets, the whole surrounded by a vacuole. Other products 

 of metabolism, vacuoles and oil droplets, are present. X 1102. 



Fig. 16. Cochlodinium vircscens sp. nov. Ventral view. The pusules are connected by a 

 long canal. Food bodies and other products of metabolism present. X 1102. 



Fig. 17. Gymnodinium translticens sp. uov. Ventral view. Surface striate, ej'toplasm filled 

 with food body and spherules. X 626. 



Fig. 18. Amphidinium fastigium sp. nov. Viewed from right side. Surface marked by 

 ridges, nucleus slightly posterior to the center, cytoplasm filled with food bodies and products of 

 metabolism. X 626. 



Fig. 19. Gymiiodinium gracilc Bergh. Ventral view. Nucleus is posterior, cj'toplasm 

 showing vacuoles, rodlets and refractive granules. X 626. 



Fig. 20. Gymnodinium auratum sp. nov. Colored by 0. Swezy. Ventral \Tiew. The 

 coarsely granular cytoplasm is nearly free from its products of metabolism. Cyst has been 

 recently formed. X 1102. 



Fig. 21. Cochlodinium pulchellum Lebour. Encysted individual with division nearly com- 

 pleted. Note the proximity of the anterior pore of the posterior daughter individual and the 

 posterior pore of the anterior daughter. X 1102. 



Fig. 22. Amphidinium scissum, sp. nov. "S'entral view. Camera drawing by iliss Inez 

 Smith. Nucleus is posterior without -visible chromatin, two large colored food masses near center 

 of body. X 1323. 



Fig. 23. Cochlodinium lehourac sp. nov. Sinistroventral view. Both pusules joined to form 

 single canal, food bodies present in cji:oplasm. Organism enclosed in thin-waUed cyst. X 1102. 



Fig. 24. Gymnodinium hcterostriatum nom. sp. nov. Ventral view. Surface heterostriate, 

 food body and other products of metabolism present in cj'toplasm. X 1102. 



Fig. 25. Cochlodinium faurei sp. nov. Dextroventral view. Note abundance of food bodies 

 and oil droplets in cytoplasm, products of metabolism. X 1102.
