Genus INGLISIA Elaskeli.

Genotype. — Inglisia patella Maskell. 



^e/erewce.— Fernald, Cat. Cocc. World, 1903, pp. 162, 163. 



Inglisia was first described by Maskell in 1879, and originally in- 

 cluded only the single species patella., which consequently stands as 

 the type. 



This species is represented in the Maskell collection by a single 

 slide of " rostrum, antennae, foot, and spiracle, June, 1881," and by 

 a very few unmounted specimens under No. 46. There is thus no 

 indication that Maskell retained in his collection the specimens he 

 studied when describing the species and genus, and it seems probable 

 that they are no longer in existence. The species is so distinct in 

 certain structural characters, however, that there would seem to be no 

 question as to the identity of the later material with that originally 

 described. 



Adult female. — The glassy external covering, as described by 

 Maskell, that is limpet-shaped; body indistinctly eight-sided, anal 

 cleft very short, derm clearing completely in potassium hydroxide, 

 convex above, but flattening without injury on mounting; antennae 

 small and short, indistinctly 7-segmented; legs small, short, normal, 

 joint between tibia and tarsus somewhat indistinct, tarsal digitules 

 slender, knobbed, but one larger than the other, claw digitules en- 

 larged, both swollen at tips, claw small and stout, without denticle; 

 mentum 1-segmented. small; spiracles small, not strongly constricted 

 in middle; marginal spines small, short, of two distinctly different 

 sorts, one stout, clavate, the other slender, tapering, straight, both 

 set in cup-shaped sockets and normally alternating ; spiraoular spines 

 not differentiated, their location indicated only by a slight marginal 

 indentation and a few quinquelocular pores; both dorsally and 

 ventrally with a few tiny, slender setae, especiall}^ near the margin, 

 and with a transverse row of the same some distance anterior to the 

 anal plates; with only slender tubular ducts, mostly along the 

 margin, probably dorsally and with a few tiny quinquelocular pores, 

 all of one size, between each spiracle and the body margin, and 

 around the anal plates; dorsally, just behind the conical apex of the 

 body, with a pair of large somewhat quadrate compound cribriform 

 plates; submarginal tubercles apparent^ wanting; anal plates small, 

 short triangular, the inner face of each from a little anterior to the 

 middle to the apex with five large " pores," presumably the in- 

 sertions for short spines, with a similar pore dorsally about a third
