ZOOPHYTOLOGY. 



Shetland Polyzoa. Collected by Mr. Barlee. (Continued.) 



2. L. Barleei, n. sp. PI. XXVI, figs. 1, 2. 



L. cellulis ovoideis, convexis, superficie granulosa ; orificio orbiculari infra 

 sinuato, peristomate simplici elevalo ; ovicell/dis decumbentibus adnalis, ad 

 marginem supra perf oralis. 



Cells ovoid, convex ; surface granular ; orifice orbicular with a sinus 

 below, peristome thin, raised ; ovicells adnate, decumbent, punctured round 

 the border above. 



Hab. Shetland, Barlee ; on shell. 



3. L. canthariformis, n. sp. PL XXVI, figs. 3, 4. 



L. cellulis late ovoideis, superjicie granulosa, punctata, nitidd ; orificio 

 tnagno, suborbiculari sett irregular/, peristomate produclo, stepitm infundfbuli- 

 f'orn/i, integro. 



Cells broadly ovoid, surface granular, punctate, shining ; orifice large, 

 suborbicular, oblong, or irregular ; peristome much produced, often infundi- 

 buliform, entire. 



Hab. Shetland, Barlee ; on shell. 



4. L. umbonata, n. sp. PI. XXVII, fig. 1. 



L. cellulis oblougis, seriatis, lined elevate sejunctis ; ad latera perforatis, 

 medio umbonatis, et juxta orificium medio avieularium mandibulo semieirculari 

 horizontali gerentibus ; orificio suborbiculari, infra paullulum conslricto, 

 peristomate simplici spiuis 4 ; supra armato ; ovicellulis umbonatis villamque 

 parvam utrinque osleiidentibus. 



Cells oblong, serial, parted by a narrow raised line, punctured on the 

 sides, and sometimes in front, with smaller pores ; furnished with a central 

 umbo, and having a prominent avieularium with a semicircular horizontal 

 mandible immediately below the orifice; orifice suborbicular, or sometimes 

 contracted below ; peristome simple, with four spines above ; ovicell large, 

 rounded, umbonate, with a small vitta or depressed area placed obliquely ou 

 each side below. 



Hab. Shetland, Bartee; on stone. 



The only species with which this can well be confounded is 

 L. verrucosa, which possesses a similar suboral avieularium, 

 but always wants, I believe, the central umbo on the cell and 

 on the ovicell, as well as the vittse on each side of the latter, 

 which are not unlike those on the ovicell of L. figularis, only 

 smaller. In L. verrucosa, also, the ovicell is punctured,
