What's the difference between perisome and peristome?
Perisome
Definition:
(n.) The entire covering of an invertebrate animal, as echinoderm or coelenterate; the integument.
Example Sentences:

(2) Examination of P14 lurchers by transmission electron microscopy indicates that the olivocerebellar fibers form synapses on Purkinje cell somatic spines and that the basket cell axons fail to form their typical perisomal nests around Purkinje cells.
(3) An analysis of this defect in lurcher may reveal how the normal transformation of olivocerebellar fibers, from perisomal to dendritic terminals, is achieved.
(4) It terminates mostly in perisomal endings in unpolarized fields throughout the LSO, though most heavily within the (high frequency) medial and middle limbs and less heavily in the LSO's (low frequency) lateral limb.
Peristome
Definition:
(n.) The fringe of teeth around the orifice of the capsule of mosses. It consists of 4, 8, 16, 32, or 64 teeth, and may be either single or double.
(n.) The lip, or edge of the aperture, of a spiral shell.
(n.) The membrane surrounding the mouth of an invertebrate animal.
Example Sentences:

(3) The specific properties of Stomahesive tested in 116 stomal and 20 fistulous patients render it really useful in stomatherapy where it increases the comfort of the patients: 1. it offers an excellent peristomal skin protection whatever the nature of the stoma or origin of the fistula; 2. it promotes rapid healing of skin lesions, even in ileostomy, transverse colostomy, ureterostomy and fistula patients; 3. it ensures an effective degree of impermeability; 4. it provides a large base for adhesion of the collecting bag; 5. it can be kept on for about 6 days in most cases; 6.
