PLATE 5 



Fig. 50. Gyrodinium mclo sp. nov. Ventral view. Note the presence of both food bodies 

 and green chromatophores. Girdle is verging towards the Cochlodinium type. X 1102. 



Fig. 51. Gymnodinium puniceum sp. nov. Ventral view. Cj'toplasm is filled with food 

 bodies. Nucleus lies on the left side of the body, posterior to the girdle. X 1102. 



Fig. 52. Gymyiodinium contractum sp. nov. Ventral view. Food bodies present. Epicone 

 furrowed. X 1102. 



Fig. 53. Cochlodinium augustum sp. nov. Ventral view. Food body present. Nucleus is 

 ellipsoid near center of body. This species represents the maximum of torsion of the body in 

 the group. X 1102. 



Fig. 54. Gyrodinium capsulatum sp. nov. Ventral view. Note the double cyst enclosing 

 the body. Surface color shown only at the margins. This approaches the Gymnodinium type 

 of girdle. X 1102. 



Fig. 55. Gymnodinium lunula Schiitt. Six zooids present, only one of which shows the red 

 granule of the single mother cell. X 1102. 



Fig. 56. Gymnodinium hetcrostriatum nom. sp. nov. This shows the presence of an ingested 

 Cochlodinium. The nucleus is anterior. X 626. 



Fig. 57. Gymnodinium doma sp. nov. Ventral view. Food body present. Note the unusual 

 size of the pusule. Peripheral color shown only at margins. X 626. 



Fig. 58. Gymnodinium ovulum sp. nov. Ventral view. Large food mass nearly fills body. 

 X 1102. 



Fig. 59. Gymnodinium multiliniatum sp. nov. Ventral view. Note peripheral zone of 

 rodlets. X 626. 



Fig. 60. Cochlodinium clarissimum sp. nov. Ventral view. Note the peripheral zone of
