Spongilltdjj (11, 20, 22, 64, 65, 66, 69). 
Weltner (69) gives the number of known species of Spongillidce as 82. 
Weltner (69) classifies the Spongillidce as follows: — Familia Spongillidce, 
Gray. 1. Subfamilia Spongillinai , Carter; Genus 1, Spongilla , 
Lamarck. 2. Subfamilia Aleyennice , Yejdovsky ; Genus 2, Trocho- 
spongilla , Vejdovsky; 3, Ephydatia , Lam. ; 4, Heteromeyenia, Potts ; 
5, Tubella, Carter ; 6, Parmula, Carter; 7, Carter ius , Potts ; 8, £7rM- 
guaya, Carter ; 9, Patamolepis , Marshall. 3. Subfamilia Lubomir- 
skinw, Weltner ; Genus 10, Lubomirskia , Dyb. 
Tbaxler (66) finds that the fossil spicules on which Ehrenberg based 
Amphidiscus antedilumanm, clavalus, Spongolithes furca , acicularis , 
injlexa , aciculira , aspera , mesogougyla , philippensis , Lithasteriscus 
iuberculatua , and Lithosphcei'idium irreg ulcere, all belong to one and 
the same species, viz., Spongilla lacustria. 
Traxeer (64) describes and figures some Spongillid spicules from the ooze 
at the bottom of the warm H6viz lake, some of which resemble the 
remarkable Amphistrongyles of Uruguaya, a genus found hitherto 
only in the tropics (Central Africa and South America). 
Traxler (65) describes and figures some Spongillid spicules from a 
“ Kiosolguhr, ,, which originally came from Brazil (probably San 
Paulo), and refers them to two species of Tubella , and one species of 
Meyenia , two of these are recent. 
Hanitscii (10) mentions 3 American species as occurring in the West of 
Ireland. 
Buck (4) mentions 4 species from the Bodensee and a pond in its vicinity. 
Hanitsch (12) redescribes the 7 species occurring in Great Britain, and 
gives figures of their spicules. 
Weltner, Arch. Naturg. 1895, describes the following new species : — 
Spongilla biseriata , loricata , p. 138 , permixta, sansibarica , p. 140. 
Ephydatia fcecunda , p. 140, forth, subtilis, p. 141. 
Heteromeyenia insignis , p. 142, Tubella multidentata, p. 142, pottsi, p. 143. 
Pai'mula cristata, p. 143. 
Urugaya amazonica, p. 144. 
Tubella thimii , Traxler, Foldtani Kozl. xxv, p. 240.

Haeckel (9) has a note on his deep-sea Keratosa, and states that “ it 
required a very careful study before I could confirm the view of Dr. 
John Murray (stated immediately after their capture) that they were 
undoubtedly true Sponges.
