122 Dr. Carl Matzdorff: Jahresbericht 
Porenkammern und durch das distale Ende des Zoöciums, das 
durch einen Querbalken und gewöhnlich einen oder zwei senkrechte 
Verbindungsbalken in Kammern getheilt ist. 
Auf Membranipora granulifera wird als neue Gattung begründet: 
Antropora gen. nov. Zooecia triangular or subtriangular, but very irregular 
in form. Calcareous portion of the area similar to that of Amphiblestrum behind, 
but here also extending up the sides and round the front, so that the membranous 
portion is completely surrounded by it, and the calcareous portion sloping inwards 
and downwards; the membranous portion with the oral opening is situated in a 
deep hollow. On the distal margin, in the place usually occupied by the oral 
spines, a pair of avicularia, with their pointed mandibles direeted inwards in 
such a way so that their tips nearly meet in the middle. There are three pair 
of lateral pore-chambers and several (four usually) lucid spots in the hind wall. 
Für Membranipora nodulosa wird aufgestellt: 
Ammatophora gen.nov. Zooecia and ooecia depressed and flattened. Zooecia 
subovate; a calcareous erest oceupying about two-thirds of the area. Oral opening 
at distal end of the membranous portion. Walls thin, terminating at the ooecium 
in a knob. Ooecium entirely separable from the zooecium, resting on the knobs 
just mentioned; of unuswal and varied from. Surface of zoarium with raised 
nodulous processes. No avicularia. No pore-chambers. 
Auf die Bildung der Zoöcien bei den Cribriliniden wird aus- 
führlich eingegangen. Uribrilina eryptooecium n. sp. (bisher mit €. 
Punctata zusammengeworfen). ©. annulata var. spitsbergensis für C. 
annulata Waters. Microporella arctica n. Sp. 
Für Lepralia spatulifera Smitt wird aufgestellt: 
Doryporella gen. nov. Zooeeia with front wall punctated, furnished with 
a median pore, in front of which is a spine with spatulate or pearshaped head. 
Orifice somewhat horseshoe-shaped, being slightly contracted at the sides and 
the proximal margin quite straight, distal margin spined. Ooecia globose, punctate, 
Avicularia at the sides of the oral opening. 
Für L. scutulata Busk: 
Harmeria gen. nov. Zooecia ovate, thin, glassy, hyaline, with a scutiform 
or ovate space on the front, distinctly cireumseribed by a raised line, within 
which the surface is punctate. Oral aperture semielliptie; lip straight in the 
younger stage, but afterwards overhung by a suboral collar-like process with 
more or less developed rostrum. No visible ooecia. No avicularia. 
Porella princeps n. sp. 
(Genauer werden Eschara, Escharoides, Escharella, Mucronella 
u. die verw. erörtert. 
Für Smittia Hincks 1879 (z. Th.) = Escharella Smitt (z. Th.) wird, 
da 1874 Holmgren die Dipterengattung Smittia aufgestellt hat, der 
Name Smittina vorgeschlagen. 
Philipps, E. 6. Report on the Polyzoa collected by Dr. Willey 
from the Loyalty Isles, New Guinea and New Britain. (Willey, A. 
Zoological Results based on material from New Britain, New Guinea, 
Loyalty Islands and elsewhere, collected during the years 1895, 1896 
and 1897, Part 4, Cambridge, 1900, S. 439 bis 450, Taf. 42, 43.)
