COCCOCHLOR1S. 311 



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

 Manual, p. 180. 



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

 with rain water at Appin : 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 genus Palmella, and according 

 with Hamatococcus 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 Hcematococcus. It there- 

 fore connects these two genera closely with each other. In 

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

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



47. COCCOCHLOKIS Spreng. 



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

 in which are imbedded the globules, filled with matter mostly 

 green and granular, to be converted into vesicles replete 

 with globules, and producing new fronds. 



Derivation. From KOKKOS, a berry, and ^Xto/ooy, green. 



The following observations on Coccochloris, which would 

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

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



" Globuli, in substrato mucoso nidulantes, materie granulari 

 farciuntur. Non tamen omnes ad evectiorem evolutionem 

 perveniunt ; nonnulli enim tantum majores dimensiones con- 

 sequuntur, eorumque interior substantia in distinctos globulos 

 confirmatur ; globuli hujusmodi propagatione inservientes vel 

 ad superficiem tantum frondis reperiuntur vel inordinate et 

 sparsae in quacumque frondis regione evolvuntur. In primo 

 illo casu a fronde matricali facile extricantur et totidem 

 novas frondes constituunt quibus ita definita forma semper 

 inest; in secundo vero primordia ilia novarum frondium a
