The author here describes and figures certain curious structures found in the 

 skin of different species of Hyalinia, to which the name of phylacites is given. 

 Each phylacite is enclosed in a parent-cell or phylacoblast, and consists of a 

 transparent body composed of a transparent and more or less granulose substance, 

 enclosing a round, ovoid or sometimes fusiform vesicle, in which are a number — 3 to 

 21 — of round or ovoid refractive spherules. The phylacoblast at first closely 

 resembles ordinary connective tissue cells, but when the development of the 

 phylacite is complete, the prostoplasmic contents and nucleus disappear. The 

 expulsion of these bodies is very rapid. In certain features they resemble 

 nematocysts and are probably defensive. The chemical composition remains 

 uncertain,

EDITOR'S NOTES. 



In the March issue (p. 32) we stated that a specimen of Plcurotomaria 

 adansoniana, Cr. & Fisch., obtained in Barbados by Surgeon-Col. .S. Archer, had 

 been presented by him to the Manchester Museum. We find, however, that we 

 were wrong in stating that this was presented by the finder. The Museum is 

 indebted, for this valuable specimen, to the generosity of Mr. K. D. Darbishire.
