80 MARINE BIOLOGY OF THE SUDANESE RED SEA. 
33. CORALLINA TENELLA, Kiitz. 
Suakim. This plant was identified for me by Dr. Reinhold. 
34. LITHOPHYLLUM AFFINE, Fosl. 
Suakim. Dr. Foslie informs me that this species is probably only a variety 
of L. Kaiserii, Heydr., or both may be varieties of the Pacific species 
L. pallescens, Fosl. 
35. GONIOLITHON MYRIACERPON, sl. 
Suakim. According to Dr. Foslie this is a variable species, and he 
identified the plant I sent him with a query. 
APPENDIX. 
The following two species of Potamogetonaceze were also present in the 
collection, viz., Cymodocea nodosa, Aschers., and Halophila stipulacea, 
Aschers. ; and also Najas marina, Linn. (Naiadacez), from Suez mud-flats. 
Fragments of Salicornia jruticosa, Linn., were also present in the same

Toure are 18 species in the collection belonging to 12 genera and 4 families. 
Of a few of these species there is a considerable quantity, but most are 
represented by a few colonies only and some by but one, or by a fragment of 
a colony. They were collected from such places as the floating stage in the 
Suez docks, the quay-side at Suakim, or from the sides of a floating buoy ; 
they are growing upon seaweeds or upon each other, and some are a good 
deal overgrown by seaweeds. They range pretty well from north to south 
of the Sudan coast.
