258 REPORT OF THE COMMISSIONER OF FISH AND FISHERIES. 
except that the 2 tails are still short and distant from each other at their 
origin. Besides they show an extreme transparency, their degree of 
refringency being very inferior to that of the psorosperm, thus easily 
escaping search in the midst of the very similarly refringent protoplasm. 
Spore.—Characters constant; body lenticular; length, 8 to 10 y.; tail 
not merely bifureate, but double from the base, this feature, however, 
being only recognizable in a portion of the profile, as when the spore is 
seen from the face one tail exactly covers the other; capsules 2, ovoid. 
Habitat—Eneysted in the muscles of Coregonus fera. 
Remarks.—Very probably this form should be correlated with the 
preceding; but as Kolesnikoff has given no measurements and Clapa- 
rede no figures, it is thought advisable to refrain irom fusing them.

No description. If Biitschl’s figures are to be depended upon, this 
species is at once distinguished from all others of the genus by the 
posterior position of the capsules. , 
Habitat.—Kidney of Lota lota L. (ling).

Definition.—Phenocystes destitute of antero-posterior, but possess- 
ing bilateral symmetry;! capsules in 1 group at the anterior end; a 
bivalve shell, the plane of junction of whose valves is perpendicular to 
the longitudinal; ? no vacuole; type genus Chloromy.xrum. 
Vacuole.——Thélohan? is authority for the statement that this 
structure is absent from the, sporoplasm of the Chloromyxid@ as here 
constituted. My observations on C. (S.) ohlmacheri confirm this. 
Pigment.—Leydig (see p. 260) notes in the myxosporidium of C, 
leydigti a yellowish coloration which he attributed to bile-staining. 
Mingazzini*t also mentions this coloration, but does not comment upon 
its origin. 
1 Imperfect from unilateral position of sporoplasm in Ceratomyaxa. 
2An examination of C. (S.) ohlmacheri has confirmed the opinion hazarded in a 
former paper (Bull. U. S. Fish Com. for 1891, x1, p. 412), that in the Chloromyxide 
the valve-junction plane is the vertical.
