Micrographs of adult males of Profilicollis altmani from Larus belcheri (Figs. 29–33) and male cystacanth (Fig. 34) from Emerita analoga on the Peruvian coastline, Lima. 29. Anterior end of the 4 tubular cement glands interfacing with the posterior testis. Note that the unequal cement glands do not extend equally anteriorly. 30. Another example of extreme unequal anterior extension of cement glands to mid-point of posterior testis (PT) reaching anterior testis (AT). Note prominent longitudinal trunk muscles (LM). 31. Posterior part of a male reproductive system showing posterior end of cement glands (CG), cement gland duct (CGD), and Saefftigen’s pouch (SP). 32. A pre-bursal perspective showing independent cement glands’ ducts and associated fibral strands (FS). 33. The bell-shaped bursa with the cement gland’s ducts channeling into the genital orifice (GO). No sensory structures were observed. 34. Developing testes in a cystacanth posterior to the second body constriction. Note the early stages of the hypodermic cells (arrows) throughout that are more developed in adults in Figure 27.
