COCCOCHLORIS. 311 



Palmella grumosa Carm., MS. P. grumosa Harv., in- 

 Manual, p. 180. 



Hah. On a rock at the sea side in a small cavity filled 

 with rain water at Appln : Captain CarmichaeL West 

 of Ireland: M'Colla. 



This species would appear to be somewhat anomalous, 

 agreeing, in the fact of the globules being immersed in a dis- 

 tinct gelatinous matrix, with the genns Pahnella, and according 

 with Hoamatococcus in the circumstance of these being sur- 

 rounded with a pellucid margin, and also in its reproduction : 

 not, however, that it is ascertained that the reproduction of 

 S. grumosa is really distinct from HcBmatococcus. It there- 

 fore connects these two genera closely with each other. In 

 diying the brick-red colour of the frond changes to a dirty 

 green, with a slight degree of gloss upon its surface. 



47. COCCOCHLORIS Spre7ig. 



Char. Frond mucous, definite, at a later period often effused, 

 in which are imbedded the globules, Jilled with matter mostly 

 green and granular, to be converted into vesicles replete 

 with globules, and producing neto fronds. 

 Derivation. From kokkos, a berry, and ■^oopo?, green. 



The following observations on Coccochloris, Avhich would 

 appear to be a tolerably well established genus, occur in ISIene- 

 ghini's " Monographia Nostochinearum," pp. 57, 58. 



" Globuli, in substrate mucoso nidulantes, matcrie granulari 

 fareiuntur. Non taraen omnes ad evectiorem evolutionem 

 perveniunt ; nonnuUi enim tantum majorcs dimcnsiones con- 

 sequuutur, eorumque interior substantia in distinctos globuloa

 ad superficiem tantum frondis reperiuntur vel inordinatas ct

 illo casu a fronde matricali facile extricantur et totidem 

 novas frondes constituunt quibus ita definita forma semper
